Introduction
Complexities of Construction
The modern construction project is so marvelously complex that it is amazing that anything ever gets built. Projects have a multitude of players, including owners, architects, engineers, the government, the general contractor, and a multitude of subcontractors and material suppliers. “Differing conditions” can impact the start, middle or end of a project. An excavator never knows how much solid rock will be beneath the surface until they start digging. In renovation projects, we never know what is behind the walls until they are torn down. Unrelated third parties, not involved in the construction process, can delay a project, including labor union strikes, war, terrorism, or trade embargos. Acts of God, including severe weather or earthquakes, can occur that are no one’s “fault.”
The beauty of this process—and the problem—is that all of these players are human beings that can misjudge and make mistakes. A material supplier that simply forgets to place an order, orders the wrong material or is unable to produce on schedule can delay a multimillion-dollar project. A masonry subcontractor cannot build walls until the concrete footings are in the right place and finished. An electrical subcontractor cannot pull wire until the wall studs are properly in place.
The general contractor is responsible for coordination of all these subcontractors. Variance in experience or competence in this coordination can dramatically impact a project.
The owner must similarly coordinate with the general contractor and architect. An owner can simply decide to change the scope of work in a project. Owners can dramatically impact project schedules by failing to respond to requests for information, failing to respond to change orders or making decisions on material selections. Funding problems from the owner or its bank can obviously impact progress, as subcontractors and suppliers may slow down or stop performance if they are not being paid. Defects in plans and specifications can easily stop a project and then change the scope of work, leaving contractors idle while design professionals decide on a solution and all players on the project fight over who will bear the costs.
Federal environmental protection laws can delay the start of a project, while discovery of toxic wastes on site can implicate federal regulations that can stop a project at any time and create much more work in remediation. A project cannot even start until local government entities approve plans and issue permits, while one overzealous or incompetent building inspector can change the description or work or create delays and inefficiencies throughout a project.
With so many individuals involved, it is amazing any project ever is completed. Construction project are almost always eventually completed, however, because of the experience, hard work, tenacity and perseverance of all the people involved.
Risk Allocation
Things are going to happen. The only thing we know with certainty is that the unexpected will occur. We just do not know what, when and who is going to pay the cost.
Changes in scope and project delays can create great costs to all players in the project. The process of risk allocation for these costs begins in contract negotiation. Owners, contractors and other players in the construction process decide who will pay the costs of problems when they negotiate a contract or when they simply decide to sign whatever contract form has been handed to them.
Clients call their lawyers constantly, telling detailed stories of problems on a construction project and asking for “the answer.” What happens? Who will bear the costs? What should I do? Most of the time, these questions are answered with another question: What does your contract say?
Most of the questions regarding claims on a construction project are answered in the contract documents. This is sometimes referred to as the “Big Boy Rule.” The parties to a construction contract are sophisticated business professionals. They are familiar with the construction process and the risks involved. They are capable of reading risk allocation provisions in their contracts, and a court will generally require them to live up to their contract. This is particularly true in a “strict construction” state such as Virginia.
The parties generally agree to what the “law” will be on this construction project when they negotiate contract terms. There are very few laws or “statutes” passed by the legislature that will relieve a contractor or owner from their agreed contract terms. One exception is “consumer” or home improvement contracts, where there is unequal experience and sophistication in construction matters. Most states have Board of Contractors regulations that restrict a contractor’s ability to enforce “unfair” contract terms on a consumer owner. Another exception is public procurement. Public owners are sometimes restricted in their freedom of contract, particularly in the bidding process. General contractors who wish to perform public work also are often restricted, in order to protect the taxpayers paying for the project and to protect the subcontractors and suppliers on the public project.
Private owners and contractors, however, have few statutory restrictions. Some states have a “Prompt Pay Act” that restricts a contractor’s ability to withhold payment from subs and suppliers.1 In Maryland, a waiver of mechanic’s lien rights in a construction contract is “void as a matter of public policy.”2 Other than these limited statutory provisions, a contractor can only hope to rely on “Implied Duties,” discussed in greater detail below. These Implied Duties generally involve some sort of bad faith, fraud, gross negligence or active interference in a contractor’s ability to perform work. The court case law on these Implied Duties are somewhat unpredictable, conflicting and inconsistent, but they are a possibility to avoid the general rule that you will be bound to or protected by the agreed contract terms.
“Changes” or “Claims” provisions in a contract will often control whether a contractor is entitled to additional time or money on a project and will dictate the procedure to follow in order to obtain that time or money. “Conduit” clauses in a subcontract will often “incorporate” the general contract terms into the subcontract, requiring the subcontractor to follow the changes, claims and dispute resolution procedures in the general contract to get additional time or money resulting from owner action. A “pay when paid clause” in a subcontract can control when or even whether a subcontractor can collect extra money for changes. “Differing” or “Concealed condition” clauses allocate the risk of unknown conditions on a construction site. These are all “risk allocation” contract provisions discussed below.
Preventing Problems
Communication and coordination are critical to prevent problems on any construction project. The need for communication and coordination drive many of the contract terms requiring notice of claims and complete information on the cost and time impact at an early stage. These notice provisions will be strictly enforced as a general rule. Sometimes this seems very unfair to a contractor that has incurred extra expenses or been delayed. An owner or general contractor, however, is entitled to know and has good reason to require clear communication that an event has occurred and exactly what the time or cost impact will be. Communication may enable an owner to alter course by rescheduling or redesigning. There are often good faith disputes about what is in the scope of the contract. One person’s change is another person’s clarification.
Most changes on a project are a “zero sum game.” One party benefits and the other has an equal amount of additional costs. A defect in the plans and specifications should mean that the contractor receives additional time and money, including profit. The owner has additional costs that the owner will try to allocate to or force on the design professional. Of course, the pushing and shoving that occurs once a problem arises may mean that both sides lose. The parties also may agree to share in the costs.
Some changes are actually a “win-win” situation. An owner may decide to enhance the project by adding new features. The contractor is entitled to additional costs and profit. The owner gets a better building.
It is important to recognize that delays are a “net loss game.” Everyone loses and there are usually no winners. No player in the construction process benefits from project delays. The project is disrupted. There are a variety of costs to all the various players. Even the player that caused the delay will suffer from disruption, costs, and delay claims against them. The innocent party is theoretically entitled to receive all costs of the delay and profit, but this rarely happens in reality. Since this is a net loss game with costs and no benefit, the parties will almost always try to push and shove the costs somewhere else. If a contractor is lucky, it will get some, but not all, of the costs. If a dispute is not resolved, the litigation costs will mean that there are no winners, except the lawyers involved.
All parties will benefit from preventing delays with careful schedule planning, communication and coordination. Good schedule planning starts with the owner and architect, and is amplified and expanded by the general contractor, subcontractors and material suppliers. Communication is critical during the bidding process, in preparations to proceed with the project and during construction. Communication regarding problems must flow in all directions: between the owner and architect, from them to the general contractor, on to subcontractors and suppliers and to or from third party participants. All contractors and suppliers must be vigilant to report problems as soon as they are apparent; that information must flow back through the general contractor to the owner and architect to minimize delays. Suppliers and subcontractors also must communicate with each other through the general contractor. Coordination among all of the contractors and suppliers on the project is possible only with prompt and clear communication.
Time is Money
We are all familiar with the adage that “Time is Money.” We experience this truth in many aspects of life, particularly business affairs. Never is this truer than in the modern construction project.
Subcontractors experiencing project delays incur costs from idle forces and idle equipment. Hourly construction workers may not get paid at all. Salaried supervisors and workers will be idle or inefficient, resulting in unrecoverable cost. Rental charges continue on equipment even if it is not being used, and use value is lost for equipment owned. Scheduling and resources available to other projects are impacted. Home office overhead costs also increase.
Often, projects are not completely shut down by delays. Partial delays result in labor and equipment inefficiencies. Forces cannot be moved to another project and increased costs result in a loss of profit. A delay on one project can mean a subcontractor is delayed in beginning another project, placing a subcontractor in an unavoidable breach of contract on the second project.
General contractors can be similarly impacted. Delays on one project can cause delays on another. General contractors also have staff, equipment and home office overhead expenses that rise on a delayed project, resulting in a loss of profit. General contractors also are responsible, however, for the coordination of and scheduling of all subcontractors on a project. If one subcontractor delays completion of a project for any reason, the other subcontractors and the owner may have claims against the general contractor for that delay.
The owner has the carrying costs for the project, including construction period interest. On a large project, an owner also will have its own staff costs for supervision and management. There are architect and engineering costs for inspection. A planned tenant for the completed building will have damage claims against the owner for delayed occupancy. If an owner plans to occupy the completed building itself, there will be lost profits and delays in opening a new business location and additional rent in their old location.
Documenting Claims
When delays or other problems occur, notice should normally be in writing, through letters, electronic mail and progress meeting minutes. Written notices promote clarity and allow all parties to pass on more complete information to all the players in the project. Written notices also are normally required pursuant to most construction contracts in order to preserve rights to time extensions or additional funds.
When projects are delayed or other claim costs are incurred, the players with the most complete documentation will have a tremendous advantage. This starts with written notices describing the time and place that problems occurred. Regularly kept daily reports will corroborate the circumstances surrounding the problem, show the personnel and equipment impacted, help establish the impact on the schedule as planned and evidence the costs incurred. Constant and consistent photographing is invaluable as an easy, inexpensive and thorough method of describing conditions.
In addition to sending your own notices, it is often important to respond to notices received. Likewise, it is often important to visit the site to view and photograph the condition before another player “cures” the alleged defect. You should review progress meeting minutes and object to entries that are inaccurate. In the event of litigation, having “the facts on your side” is certainly important. It is equally important, however, to have good evidence to support your facts.
In the event of serious problems and large costs, it is important to get independent third party witnesses and experts involved as problems occur. Experts can help show conflicts or defects in plans, help get a project back on schedule or limit damages. Any independent third party witness, including experts, can be very helpful as witnesses in litigation to establish the causes and costs of changes.
Litigating Claims
A good understanding of claims and defenses will help any contractor know when it is important to send notices of problems and how to preserve evidence of costs. We hope that these materials will be helpful toward that end.
Because of the potentially significant costs of project delays and other problems, owners and contractors try to shift risks and costs to others. The process of risk allocation takes place in contract negotiation. A good understanding of contract clauses impacting claims issues will help contractors negotiate a contract avoiding undue risk of delay and other claim costs.
Once a delay or other change occurs, owners and contractors also quickly engage in cost shifting. This often starts with the “blame game” and sometimes ends in litigation. By this time, the players are normally stuck with the contract provisions they agreed to, but there is often a great deal of legal maneuvers in attempts to avoid notice requirements, liquidated damages, no damage for delay and other contract clauses. A good understanding of contract clauses will help players protect their insulation from claims and to support claims that they may have against others.
Good lawyers and experts also are critical in delay and claims litigation. Claims litigation is very complex, and experience is essential. Good experienced lawyers and experts, however, also are very expensive.
Any player considering pursuing a delay or other claim should carefully evaluate the costs relative to any possible recovery. Better knowledge of contract clauses and claim litigation will better enable you to preserve your rights and defenses to claims, but you also will be in a better position to evaluate whether a claim is worth pursuing.
Delay claims are particularly “fact intensive.” Large construction projects can take months or years to complete. Delay claims can involve an analysis of events occurring daily for all of those months or years, involving an evaluation of schedules, correspondence and daily reports from the owner, general contractor and all of the subcontractors. It may be necessary to pay a lawyer and an expert hundreds of dollars an hour to acquire, review and evaluate boxes of documents—and then organize that material for a clear and cogent presentation to a court or arbitrator. In arbitration, you also pay an arbitrator hundreds of dollars an hour to go through the same process.
The reality of most construction projects is that much of this documentary evidence is missing or conflicting. All parties in the litigation will develop evidence that leads to different results. Sometimes contract clauses also conflict. Legal theories sometimes allow litigants to circumvent what are otherwise clear contract provisions. All of this results in uncertainty, risk and cost in claims litigation.
People often forget that there are three “essential elements” or “parts” to a contract claim: You must prove the contract, prove breach and prove your damages. Many clients tell compelling stories of increased and unexpected costs, but they are not recoverable unless the client can prove that someone else had the risk of these problems.
In some disputes, the claimant will fail on the first element. If a landscaper plants beautiful trees on the wrong lot, without the owner’s knowledge or agreement, the landscaper will fail to recover. There is no contract, even though there are damages. Subcontractors will usually fail to recover from an owner for problems caused by the owner. There is no “privity of contract.” The sub has a contract with the general contractor, but the problem caused by the owner may not be a risk that the general contractor agreed to assume in the subcontract. A general contractor can agree to pursue a subcontractor’s claims against the owner, but now we have to look at the contract between the owner and general. Can the general recover this claim under its contract with the owner? On construction projects, there is usually no question that there is a contract. The issues will be what is within the scope of that contract and what are the limitations of liability or risk allocation.
Once you establish the terms of the contract, you must prove that the defendant breached the contract and that the problems are the defendant’s “fault.” No contractor in history has ever built a project exactly according to plans and specifications or exactly according to schedule. No set of plans is ever perfect, and there are often conflicts or ambiguities in the contract or in the plans. The parties can spend much time arguing over exactly what any of the contract documents say and who caused or contributed to the problems.
Even if you can clearly establish problems caused by another player that are a breach of this particular contract, it is still necessary to prove your damage “with reasonable certainty.” Even if it is clear that the owner caused a problem that is a breach of this contract, the plaintiff still must prove exactly what damage was caused by that problem. It is particularly difficult to prove damages caused by delay. There are various methodologies to establish damages from delay. These methodologies will often result in radically different calculations of damage. Some methodologies are more favored by various courts or arbitrators. It is often difficult to predict which methodology your court or arbitrator will use. Experts can often earnestly support or discredit any methodology in a particular factual situation. All of this again results in uncertainty, risk and cost in litigation.
Even if it is clear that a claimant has been delayed and has suffered damage, the exact cause of that delay or the proper calculation of damages often is not at all clear. The proper calculation of delay damage may lead to a damage recovery lower than the contractor earnestly feels was incurred. Recovery is often less than the damage actually incurred.
When a contractor is in litigation, it is often tempting to add a delay claim to other damages. If you are “going to court anyway,” why not “go for everything we can get.” This strategy can often backfire, however. The delay and other claims often unnecessarily overcomplicate a case and increase costs dramatically, with a limited chance of recovery because of limited documentary evidence, limiting contract clauses or difficulties in proving actual damage.
CONTRACT CLAUSES AND THEORIES
The guidepost in determining the legal responsibilities of the parties is the contract itself. The contract constitutes the law that governs the parties’ relationship.3 Where sophisticated business professionals enter into an arms-length transaction, a court will enforce the terms of the agreement absent some compelling reason that enforcement would be unreasonable or unjust.4 When an agreement is plain and unambiguous in its terms, it will be given full effect.5 Legal clients often want to tell their lawyer a story and then ask, “What is the answer?” The “answer” usually is that “we need to read your contract to know.” Construction industry buyers and sellers are sophisticated business professionals. They will be held to the terms in their contract documents. The construction industry generally works with sophisticated and detailed contract form documents that determine the result of most events on a construction project.
Conduit or Pass Through Relationship
Many construction subcontracts state that the provisions of the general contract will bind the subcontractor or supplier. Such contracts sometimes state that the subcontractor or supplier shall be bound to the general contractor to the same extent that the general contractor is bound to the owner. Such provisions have become very common in the marketplace and are generally enforceable. Conduit or pass provisions can impact or even control a subcontractor’s right or ability to collect for changes, delays and other claims.
A conduit clause or incorporation of the general contract can create duties in the general contractor and give a subcontractor rights.6
A subcontractor should obtain a copy of the general contract during the bidding process or before executing a subcontract. It is often more difficult to obtain any information once a dispute exists. Most general contractors are willing to provide copies of their general contract, although they may wish to “black out” the financial terms and may make the general contract available for review only at the general contractor’s office.
It is, of course, the best practice for a subcontractor to review the general contract to determine the risk in agreeing to be bound. Even if a subcontractor will not have time to review the entire general contract, it will still be important to have it on hand in the event of future changes in work, claims or disputes. A subcontractor will have a harder time getting a copy once there is a dispute.
A subcontractor will want to pay special attention to time deadlines in the general contract for making claims for extra time or change orders to the owner. As discussed below in Claims Procedures, the general contract may have specific restrictions on when contractors can make such a claim or how they must make such a claim. A subcontractor also should look at the dispute resolution procedures. A subcontractor may be bound to arbitration or bound to let the architect decide on a claim before filing suit.
Payment Terms and Pay When Paid
“Pay When Paid” clauses are an important feature of most conduit or pass through relationships and have become very common in the marketplace. If the subcontract clearly states that payment by the owner is a “condition precedent,” then the general contractor is not obligated to pay unless and until the general contractor has been paid.7 Condition precedent pay when paid provisions can obviously impact a subcontractor’s right or ability to collect for changes, delays and other claims.
This essentially shifts the credit risk of project failure or owner insolvency to the subcontractor. Subcontractors obviously would prefer to eliminate this term from the contract if possible. In any event, however, it is important to recognize this situation when analyzing risks. A subcontractor now must analyze the creditworthiness of the owner and the quality of that project. If the owner of the project becomes insolvent or if this project fails, the general contractor will have no obligation to pay subcontractors.
If a condition precedent pay when paid clause is in your contract, you will want the same term in lower tier subcontracts. If the credit risk has been shifted to you, you want to keep passing it down the line. In modern construction contracts, the cost of a payment problem usually ends up with the contractor down the line who was handed the hot potato and failed to throw it to the next contractor.
One party to the contract cannot prevent occurrence of the condition precedent and then take advantage of the nonoccurrence to excuse performance. If a general contractor prevents or hinders payment from the owner, the condition may be waived or excused.8 This is known as the “prevention doctrine,” which is discussed in more detail below under Implied Duties.
If a pay when paid clause says only that the customer will pay “within five days after receiving payment,” this may not be a condition precedent. Courts have held that such a “pay when paid” term simply defines the time for payment and does not eliminate the need to pay eventually.9 This type of pay when paid clause is found in AIA contract documents, for example, and is not as big a concern to subcontractors as the condition precedent pay if paid clause.
Some states do have laws that limit the effectiveness of “pay if paid” condition precedent clauses. See the appendices of the Construction Law Survival Manual for a 50-state survey of statutory protections against pay when paid clauses.
Change Orders
Most construction contracts state that there will be no payment for changes in the work unless ordered in a signed writing. These clauses are generally enforceable and can obviously impact a contractor’s right or ability to collect for changes, delays and other claims. If the contract has a written change order clause, the contractor may not get paid unless there is a written change order.10 It does not matter how much work was done, how much it cost or who ordered the work. Written change order clauses are actually required by many state licensing statutes or regulations.11
Owners, general contractors and other upstream contractors are entitled to know if extra charges are involved before the work is performed. One person’s change order is another’s clarification.12 An owner or general contractor may order work, thinking they are only providing instructions on details already included in the contract price. The most important function of a written change order is that it requires both owner and contractor to slow down and agree on whether this item is covered by the contract and what the compensation will be. Whether or not the contract has a written change order clause, field representatives should stop work, request a clear understanding and a change order (or at least a written directive) before change work is performed.
The most important thing to establish in writing is that the work is a change and will result in additional time and money. Establishing the precise price or time adjustment is not as difficult. A sample Change Order form is provided as an appendix. The sample form allows a fixed sum or a cost plus agreement. If you can’t agree on anything else, a contractor should carefully describe the work being performed and get the form signed. This means that there will be payment for the work at a price to be established, considering the reasonable value of the labor and materials. Establishing the exact price later will not be as difficult as establishing that the work was a change.
Contractors should be sure to establish an extension of time for the change, as well. Changes to a contract scope will generally entitle a contractor to additional time,13 but many contracts require notice or additional procedures to preserve that right. Many contractors remember to get a written change order but forget about the contract time. It doesn’t do you any good to get an extra $500 for a change if the additional work means that the contract is completed four days later and you are assessed $1,000 in liquidated damages. The Change Order form in the appendix has a default mechanism stating the contract time will be adjusted “by an equitable amount of time, if no time estimate is available.” The form also allows the contractor to verify funding for the change.
If it is impossible to get a signed change order or work must begin immediately, the contractor has a “claim.” The claims provisions in the contract become important, particularly written notice requirements. This is discussed in greater detail below in the subsection on Claims Procedures. Needless to say, the most important thing is to document claims. Normally, a contractor must perform the work “under protest” or at least make it clear in writing that the contractor considers this work to be a change under the contract. Written notice is normally required before, or soon after, beginning change work, followed by pricing data soon after the work is complete. Promptly sending a proposed change order complete with pricing data and time extension will normally satisfy these claim requirements.
The fact that a contract contains no provision for extra work does not prevent recovery for the fair value of work performed beyond the scope of the contract. This fair value would include reasonable overhead and profit.14
Claims Procedures and Notice Requirements
To properly preserve claims, it is very important to read your contract, review any general contract incorporated into your contract, review any state or municipal procurement statute that may be applicable and make sure that you are following the claims procedures, particularly requirements for notice of claims for additional time or money. A court will enforce these procedures. If you fail to follow all required steps, you will not be able to collect the extra money or the extra time that was lost.
Most general contracts and subcontracts provide detailed procedures to make any claim for extra time or money. You may not have an opportunity to change the claims procedures in either the general contract or your subcontract. It is very important to understand the procedures, however, and make sure that you comply. Claims procedures may require “written notice of any claim within 48 hours of the event giving rise to the claim.” Courts will enforce this type of clause. If a subcontractor does not give sufficient notice to the general contractor (within the time and in the manner required by the general contract), then the general contractor will not be able to compel payment by the owner. This is the nature of the conduit relationship. If you fail to provide such written notice, you may not have a claim, no matter who caused the problem or how much it cost.15
The American Institute of Architects (AIA) Document A201-1997 (General Conditions of the Contract for Construction) states:
4.3 Claims and Disputes
4.3.1 Definition. A Claim is a demand or assertion by one of the parties seeking, as a matter of right, adjustment or interpretation of Contract terms, payment of money, extension of time or other relief with respect to the terms of the Contract. The term “Claim” also includes other disputes and matters in question between the Owner and Contractor arising out of or relating to the Contract. Claims must be initiated by written notice. The responsibility to substantiate Claims shall rest with the party making the Claim.
4.3.2 Time Limits on Claims. Claims by either party must be initiated within 21 days after occurrence of the event giving rise to such Claim or within 21 days after the claimant first recognizes the condition giving rise to the Claim, whichever is later. Claims must be initiated by written notice to the Architect and the other party.
Project managers should have a procedure to send written notice about any events that may later give rise to a claim. It is often best to have a regular policy of sending weekly or biweekly “status” or “progress” letters. Owners and general contractors generally appreciate a contractor that is organized and keeps them informed about the status of the contractor’s work, their anticipated schedule going forward and problems caused by others. This also is an opportunity to describe all problems or events encountered that may give rise to a claim.
If a contractor later finds that it failed to provide written notice of a claim in the precise manner required by the contract documents, they may be able to “piece together” adequate notice from a variety of sources. Courts may enforce an oral agreement or find a waiver of written notice requirements.16 Written notice, however, will always be better than verbal. Witnesses are often unavailable later or their memories will fade, and witnesses will disagree on exactly what was said and when. Progress meeting minutes, emails and other correspondence, however, can provide adequate written notice that a claim was made or at least that an owner or general contractor was made aware of a condition.
There is no question your chances of recovering a claim will improve if you send clear written notice in compliance with the contract documents.17 Your ability to use alternate methods will depend on the court or arbitrator deciding your case and the “fairness” or other circumstances on the project. Important factors include how clear it is that there has been a change in the scope of work or schedule, how clear it is that the owner had actual notice of the condition, and whether the owner could have modified the work or schedule on receipt of notice to avoid the costs of the condition.
Many claimed “changes” result in a dispute over the actual scope of work, because of ambiguities or conflicts in the contract documents. If it is arguable whether there is a “change” at all, the notice requirements will be more important. If there is clear evidence that an owner is aware of a condition or aware that a contractor is performing a change, contractual notice may be less important. Notice to the architect, however, may not qualify as notice to the owner.18 The owner bears the costs of changes and is entitled to make decisions that impact costs.
Owners are entitled to notice of a potential claim, particularly if they could have done something to avoid the costs if they had received notice. If you are delayed because the owner left equipment in the way, you may not have a claim unless you provide notice that the equipment is in the way and you are delayed as a result. If the owner received the notice, they may be able to simply move the equipment. In this context, an estimate of the anticipated costs or time impact in a notice can be as important to an owner as notice of the condition.
Claims procedures often require detailed cost or time impact information within a certain period of time. If costs are continuing or if you will need more time to document your costs, it is still important to send a letter reiterating that you are incurring ongoing costs, explaining what you do know about the total costs and stating that a complete claim will be submitted when work is complete and information is available.
It does seem the initial “notice” requirement of the contract will be more strictly enforced by the courts than the “claim” or final cost requirements. Often, it is impossible to know the full cost or time impact of a condition until work has progressed or been completed. The owner or general contractor also is better able to avoid problems if they receive timely initial notice of the adverse condition. The final claim and final cost are less likely to impact behavior, because it is often too late. A claimant should provide accurate cost and time impact data as early as possible, however, especially if it is required by the contract, it is possible to make a prompt cost or schedule computation, or there would still be time to decide on another course of action if costs are higher than expected.
Initial notices or final claims may have to be submitted to the architect or the general contractor first. It may then be necessary to send a second notice of the claim if the architect fails to respond or gives a negative response. Contractors must follow all of these procedures if they are required by the contract.
If a contractor is delayed in performance, some contracts limit the remedy to a time extension. The contractor will be unable to claim the extra costs incurred as a result of the delay. Delay costs can be considerable, especially if you must keep your personnel on the job throughout the delay or if delays on one project keep you from performing on another. You could incur large liquidated damages on a project, for example, if delay on another project leaves you short of manpower. Contractors would obviously prefer to preserve rights to these costs by striking out language in a contract that limits remedies to time extensions.
Conduit claims procedures in subcontracts often state that subcontractors will receive extra time or money only if the general contractor receives the same from the owner. This is understandable in the sense that a general contractor would not want to cover out-of-pocket expenses for labor or material if an owner can successfully show that the event was not a change under the general contract. Subcontractors should be careful, however, to preserve rights if the event is caused by the mistake or omission of the general contractor.
Dispute Resolution Procedures
Many general contracts and subcontracts also provide procedures to resolve any disputes. A conduit clause in a subcontract can require a subcontractor to follow the dispute resolution procedure in the general contract, particularly for disputes involving the owner. You may need to submit disputes to the architect or some third party before you are allowed to demand arbitration or litigate. You must be aware of these dispute resolution clauses, so that you do not waste time and money using the wrong procedure. Even worse, you can forfeit your right to many claims if you follow the incorrect procedure, particularly in government projects with administrative claims procedures.19
Arbitration clauses are a particular problem in many cases.20 In Maryland mechanic’s lien cases, a claimant has no lien until a court hearing establishes the lien.21 If the court stays your lien action because of an arbitration provision, your lien rights may be cut off by a bankruptcy or a sale of the property while you are off in arbitration.22
Arbitration clauses also can be a particular problem for subcontractors in bond claims. They may be unable to arbitrate with the bonding company, because that bonding company did not agree to an arbitration provision in the bond. This can leave a subcontractor in the position of litigating the same case twice.
Monitoring and Verifying Funds for the Project
Change orders, delays and cost overruns are often the cause of a project’s failure. An inexperienced owner or architect and a bad set of plans can cause terrific overruns. Contractors often view this as their very objective, but this is often shortsighted. If the project fails or there is not enough money to finish, a contractor may not collect for change order work performed. This is particularly a problem for subcontractors with a “pay if paid” clause in their contract.23
An owner may begin ordering changes because of a bad set of plans or because he wants to build the Taj Mahal, but has the lender agreed to fund these changes? The owner may even keep the lender in the dark because the owner does not want the lender to know there are problems. Toward the end of the project, there is another $300,000 worth of work to do, $200,000 in retention held and no money left on the construction loan. The owner then begins defaulting on payments to the contractors and to the lender.
Delays and accelerations present the same problem. These are, in effect, change orders. Is there enough money to pay for the acceleration or to compensate for delays? A contractor should continually monitor the financial health of the project as much as possible. This is especially important with a cost plus contract or when substantial change orders are requested.
The most important term would include the right to verify adequate funds to complete the project before the project begins and at various later stages of the project. At a minimum, the contractor should have the right to verify funding for change orders in excess of a certain dollar amount. In the case of a cost plus time and materials contract, the seller should be able to verify funding once the original budget is surpassed.
In any event, the seller should have the contractual right to refuse to perform any further work if adequate funding cannot be established. This term appears in AIA Document A201-1997 (General Conditions of the Contract for Construction), which reads:
2.2.1 The Owner shall, at the written request of the Contractor, prior to commencement of the Work and thereafter, furnish to the Contractor reasonable evidence that financial arrangements have been made to fulfill the Owner’s obligations under the Contract. Furnishing of such evidence shall be a condition precedent to commencement or continuation of the Work. After such evidence has been furnished, the Owner shall not materially vary such financial arrangements without prior notice to the Contractor.
It also is helpful to have the right to consult persons who may have knowledge concerning the health of the project, funding, scheduling, expected changes and other matters. You also may consider the right to run credit checks on the general contractor or owner.24
Defects in Plans and Specifications
An owner that had plans and specifications prepared is generally responsible for defects in those plans and specifications.25 An owner is entitled to make changes, but where the change is necessitated by defective plans or specifications, the owner must pay the entire resulting damage. When the owner provides the plans and specifications, it implicitly warrants that compliance with the specifications will result in satisfactory performance.26
A construction contractor who has followed plans and specifications furnished by the owner that are defective or insufficient will not be responsible to the owner for loss or damage, which results solely from the defective or insufficient plans and specifications in the absence of negligence on the contractor’s part, or any express guarantee or warranty that the plans and specifications are sufficient or free from defects.27 A contractor who bids for work has the right to rely on the plans and specifications submitted to him for bidding purposes. The rights of the parties are to be measured by them. It is only through the plans and specifications that he can make an intelligent bid. Burdens other than those contemplated by the contract may not be placed on the contractor without additional compensation.28
The owner also is responsible for delays caused by faulty plans and specifications, including the failure to recognize the need for revisions in the plans and failure to make those revisions in a timely manner.29
When a general contractor supplies a subcontractor with plans prepared by the owner’s design professional, the general contractor impliedly warrants those plans to the subcontractor. Absent open and obvious design defects, which should be apparent to a prudent contractor and called to a prime contractor’s attention, the party who furnished plans and specifications impliedly warrants them to be fit for their intended use.30
Differing or Concealed Site Conditions
In general terms, if a contractor agrees to construct an improvement for a stipulated sum, the contractor bears the risk and costs of concealed conditions. The contractor will not be excused or be entitled to additional compensation when unforeseen difficulties are encountered.31 If a contractor agrees to erect a structure on a particular site, the contractor ordinarily assumes the risk of subsidence of the soil.32
The risk of concealed conditions would normally cause a contractor to add large contingency amounts in a fixed price contract. As a result, owners would pay increased prices for projects, even if differing or concealed conditions are not encountered. To reduce the risk, the contingency and the price to the owner, many contracts include a differing or concealed site condition clause.
AIA Document A201-1997 (General Conditions of the Contract for Construction) removes the risk of differing or concealed site conditions from the contractor. It states:
4.3.4 Claims for Concealed or Unknown Conditions. If conditions are encountered at the site which are (1) subsurface or otherwise concealed physical conditions which differ materially from those indicated in the Contract Documents or (2) unknown physical conditions of an unusual nature, which differ materially from those ordinarily found to exist and generally recognized as inherent in construction activities of the character provided for in the Contract Documents, then notice by the observing party shall be given to the other party promptly before conditions are disturbed and in no event later than 21 days after first observance of the conditions. The Architect will promptly investigate such conditions and, if they differ materially and cause an increase or decrease in the Contractor’s cost of, or time required for, performance of any part of the Work, will recommend an equitable adjustment in the Contract Sum or Contract Time, or both. If the Architect determines that the conditions at the site are not materially different from those indicated in the Contract Documents and that no change in the terms of the Contract is justified, the Architect shall so notify the Owner and Contractor in writing, stating the reasons. Claims by either party in opposition to such determination must be made within 21 days after the Architect has given notice of the decision. If the conditions encountered are materially different, the Contract Sum and Contract Time shall be equitably adjusted, but if the Owner and Contractor cannot agree on an adjustment in the Contract Sum or Contract Time, the adjustment shall be referred to the Architect for initial determination, subject to further proceedings pursuant to Paragraph 4.4.
This contract provision splits concealed or unknown conditions into two “Types.” A “Type I” condition concerns “subsurface or otherwise concealed physical conditions, which differ materially from those indicated in the contract documents.” This type of claim depends on an inaccurate representation in the plans, specifications, test borings, soil reports or other contract documents.
A “Type II” condition is “unknown physical conditions of an unusual nature, which differ materially from those ordinarily found to exist and generally recognized as inherent in construction activities of the character provided for in the contract documents.” This type of claim does not depend on an inaccuracy in contract documents, but does require a physical condition that was unknown and of an unusual nature.
U.S. government contract documents and Federal Acquisition Regulations generally describe differing site conditions in the same manner.33 Accordingly, differing or concealed conditions are generally split up into and described as Type I and Type II conditions in the construction industry.
Even in the absence of a differing site conditions clause in the contract, a Type I condition claim based on defects in the contract documents can be brought under a theory of “misrepresentation” by the owner34 or based on the owner’s “implied warranty of the accuracy of the plan and specifications.”35
To avoid being bound to soils reports and other contract documents, owners sometimes include explicit disclaimers. The effectiveness of these disclaimers seems to vary.36 The Virginia Supreme Court has upheld a disclaimer from an owner that provided a soils report “solely as a matter of convenience and general information,” and expressly disclaimed “any responsibility for the data as being representative of the conditions and materials which may be encountered.”37
By definition, a Type II condition is not described in the contract documents. It must be an unknown physical condition of an unusual nature. If the condition is shown on any contract documents or discussed in any pre-bid conference, it cannot be unknown and a Type II condition claim will be denied.38
Type II condition claims also must be for physical conditions. Claims will not be allowed under these differing site condition clauses for non-physical conditions such as labor disputes, governmental, political, economic or weather conditions.
Differing or concealed conditions provisions in a contract normally have notice requirements similar to those for changes or delays. This allows the owner or architect to inspect and verify the condition, formulate the best method of proceeding and perhaps alter the work to avoid excessive cost increases.39 If the contractor fails to strictly follow the notice requirements, however, courts may allow the claim anyway if the owner had actual notice of the condition and can prove no prejudice or damage due to the late notice.40
The ability to obtain a time extension or make a delay claim for a differing or concealed site condition will depend on all of the same requirements for making a claim for additional compensation.
Site Investigation
A construction contract often includes an obligation by the contractor to fully investigate and inspect the site prior to signing the contract. A site investigation provision may read as follows:
The contractor represents that it is fully qualified to perform the work required by this contract and acknowledges that prior to the execution of this contract it has by its own independent investigation: ascertain the conditions involved in performing its work, including but not restricted to: the location of the work; accessibility and character of the site; quality and quantity of surface and subsurface water; materials or obstacles to be encountered; the character and extent of existing work within or adjacent thereto; other work being performed thereto; transportation, disposal, handling and storage of materials; availability of labor and labor scales; location and availability of utilities and access roads; equipment and facilities needed for the prosecution of the work; uncertainties of weather or physical conditions at the site; and any other matters which can in any way affect the work or the cost thereof.
On its face, this provision places a significant responsibility on the contractor to investigate the proposed construction site and conditions. There are limitations to the responsibility and risk placed on a contractor by such a provision. As described in the prior subsection, most construction contracts contain a Differing Site Conditions or Concealed Site Conditions clause. As described above, the contractor is not responsible for the consequences of defects in the plan and specifications.41 This responsibility of the owner is not overcome by a clause requiring contractors to visit the site, to check the plans and to inform themselves of the requirements of the work. The contractor should be relieved if misled by erroneous statements in the plan and specifications.42
AIA Document A201-1997 (General Conditions of the Contract for Construction) does not attempt to shift the risk of differing or concealed site conditions or defects in the plans and specifications to the contractor. It states:
3.2 REVIEW OF CONTRACT DOCUMENTS AND FIELD CONDITIONS BY CONTRACTOR
3.2.1 Since the Contract Documents are complementary, before starting each portion of the work, the Contractor shall carefully study and compare the various Drawings and other Contract Documents relative to that portion of the Work, as well as the information furnished by the Owner pursuant to Subparagraph 2.2.3, shall take field measurements of any existing conditions related to that portion of the Work and shall observe any conditions at the site affecting it. These obligations are for the purpose of facilitating construction by the Contractor and are not for the purpose of discovering errors, omissions, or inconsistencies in the Contract Documents; however, any errors, inconsistencies or omissions discovered by the Contractor shall be reported promptly to the Architect as a request for information in such form as the Architect may require.
Clauses requiring the contractor to perform its own pre-bid site investigation are enforced to varying degrees.43 If the conditions would have been obvious to a “reasonably experienced and prudent” contractor examining the site, however, the risk is probably with the contractor.
Schedule Preparation and Updating
Contract documents often assign schedule preparation and updating duties to one or more of the players on the project. As a practical matter, this also will assign “fault” if the schedule is unrealistic or incorrect. AIA Document A201-1997 (General Conditions of the Contract for Construction) states:
3.10.1 The Contractor, promptly after being awarded the Contact, shall prepare and submit for the Owner’s and Architect’s information a Contractor’s construction schedule for the Work. The schedule shall not exceed time limits current under the Contract Documents, shall be revised at appropriate intervals as required by the conditions of the Work and Project, shall be related to the entire Project to the extent required by the Contract Documents, and shall provide for expeditious and practicable execution of the Work.
Subcontract documents will typically state that the subcontractor must similarly provide its schedule before or soon after the award of the subcontract to enable the general contractor to complete a realistic schedule for the owner.
The requirements for development of a schedule will assist in preparation of a realistic schedule for the project. A contractor is in a better position than the owner or architect to know exactly how long various tasks will take for this particular contractor in this particular market.
Schedule updates are often required at the time of any delay or potential delay and are often referred to as a “time impact analysis.” This provides full notice of the impact any change or delay will have on the project schedule as a whole and enable the owner to adjust as necessary to avoid unnecessary delay.
Contract Schedule Unilateral Amendments
Many contracts also provide that the owner or general contractor can unilaterally modify the schedule. Such a scheduling provision may read:
Should the contractor provide the Subcontractor with progress schedules or any kind of time analysis for the performance of the work, it is understood and agreed that said schedules are offered as an aid to the Construction process only. However, it is further understood and agreed that such schedules are not guarantees that the Subcontractor’s work will be performed within the time periods or durations or in the sequence set forth therein and such schedules may accordingly be changed or revised by the Contractor, in its sole discretion, from time to time as circumstances may require. Such schedules, if any, do not relieve the Subcontractor of the obligation, as set forth herein, to follow the progress of the work and the directions of the Contractor. Nothing herein will be construed as requiring the Contractor, either expressly or impliedly, to furnish the Subcontractor with progress schedules for the Subcontractor’s work.
The Subcontractor will proceed with the work in a prompt and diligent manner, in accordance with the Contractor’s schedules as amended form time to time. The Subcontractor will be liable to the Contractor for failure to adhere to the Contractor’s schedules, including amendments, even if such schedules differ materially form schedules set forth in the Contract Documents or the time of completion called for by the Contract Documents. TIME IS OF THE ESSENCE.
This may put a contractor in an unavoidable default. The contractor will be in default, for example, if the production time is cut in half or the length of a project doubled. A contractor may not have the manpower to complete production in less time and may not have a claim for overtime or other costs. Project extensions also can be troublesome if the contractor has already committed to other projects.
A contractor may know that it needs a certain amount of time to mobilize on a project, to order materials or to take measurements to begin work. If so, a contractor wants to make sure the contract says so. Contractors also generally prefer a definite starting date in their contract, rather than a need to mobilize immediately on a “notice to proceed.” Then, if the start of the project is delayed, the contractor may have a claim for overtime or disruption of their schedule on other projects.
It is a good policy for contractors to attach an actual projected contract schedule as an exhibit to the contract or to reference an actual schedule in existence at the time of the contract and eliminate any terms allowing changes to this schedule without consent or at least disallowing “unreasonable” changes. A defined schedule will cut both ways. If the actual projected contract schedule is attached as an exhibit, then the contractor will probably need to keep up with this schedule. If possible, contractors want to allow for some flexibility in their own scheduling.
Responsibility for Coordination
AIA Document A201-1997 (General Conditions of the Contract for Construction) states:
3.3 Supervision and Construction Procedures
3.3.1 The Contractor shall supervise and direct the Work, using the Contractor’s best skill and attention. The Contractor shall be solely responsible for and have control over construction means, methods, techniques, sequences and procedures and for coordinating all portions of the Work under the Contract, unless the Contract Documents give other specific instructions concerning these matters.
This contract provision, very common in all types of construction contracts, gives the general contractor the right and the responsibility to coordinate all forces on the project in order to complete the project in a timely manner.
In the event there is work performed by the owner’s own forces or the owner’s separate contractors, the AIA Document A201-1997 (General Conditions of the Contract for Construction) states:
6.1.3 The Owner shall provide for coordination of the activities of the Owner’s own forces and of each separate contractor with the Work of the Contractor, who shall cooperate with them. The Contractor shall participate with other separate contractors and the Owner in reviewing their construction schedules when directed to do so. The Contractor shall make any revisions to the construction schedule deemed necessary after a joint review and mutual agreement. The construction schedules shall then constitute the schedules to be used by the Contractor, separate contractors and the Owner until subsequently revised.
Without such a contract provision, an owner may not have a duty to schedule and coordinate multiple prime contractors.44
Contract Duration and Schedule
Most contracts provide a specific delivery schedule. This will leave the contractor in default and liable for delay damages if the completion date is not met.45 The completion date also provides the contractor a specific time to complete its work and an owner may not shorten this time.46 A delay in the completion date can result in a contractor claim for price increases.47 Delay by a general contractor in accepting a bid may release the subcontractor from a bid.48
When a contract does not specify a time for performance, the law implies a reasonable time.49
Time of the Essence
Most construction contracts will state that “Time is of the Essence.” As in most contracts, this means what it says in a construction contract. In the absence of an “excusable delay” or “force majeure” term in the contract, a time is of the essence clause can leave a contractor liable for damages in the event of delay, even if the contractor did not cause the delay.50 If the contract does not make time of the essence and there is no required completion date, the work must be complete within a reasonable time.51 A purchase order with a definite delivery date can make time of the essence for a material supplier.52
Force Majeure and Excusable Delays
Most contracts state that a contractor is not responsible for delays from causes beyond the contractor’s control. In fact, some state contractor’s regulations require such an explicit “force majeure” clause in contracts.53
AIA Document A201-1997 (General Conditions of the Contract for Construction) states:
8.3 Delays and Extensions of Time
8.3.1 If the Contractor is delayed at any time in the commencement or progress of the Work by an act or neglect of the Owner or Architect, or of an employee of either, or of a separate contractor employed by the Owner, or by changes ordered in the Work, or by labor disputes, fire, unusual delay in deliveries, unavoidable casualties or other causes beyond the Contractor’s control, or by delay authorized by the Owner pending mediation and arbitration, or by other causes which the Architect determines may justify delay, then the Contract Time shall be extended by Change Order for such reasonable time as the Architect may determine.
This type of force majeure clause entitles a contractor to a time extension only. The contractor is protected from liquidated damage or other claims for delays beyond the contractor’s control, but the contractor’s affirmative claim for compensation for the delay will be controlled by other contract provisions. The ability to get even a time extension is dependant on the terms of the contract, especially timely notice requirements. A time extension clause in a contract does not necessarily provide an exemption from damages for delay.54
In order to obtain even a time extension under a force majeure clause, the contractor usually must prove that the delay was truly beyond the contractor’s control and that the delay was unexpected, unusual or out of the ordinary. The essence of an excusable delay is that the cause is unforeseeable, beyond the control of the contractor and without his fault or negligence.55
If extensions of time are authorized only for “adverse weather conditions not reasonably anticipated,” a contractor must be ready to prove that the adverse weather conditions were extraordinary.56 Unforeseeablity is often a difficult element to establish, particularly when delay is caused by a subcontractor or supplier.57 A subcontractor must sometimes prove that it took all practicable efforts to over come a delay to establish that the delay was beyond the contractor’s control.58
Material Supplier Deliveries
A material supplier must deliver goods within a “reasonable time” if the parties have not agreed on any other schedule.59 This is vague, but it does mean something. In most markets, it is not reasonable for a lumberyard to deliver two months after an order.
What is reasonable will vary depending on such factors as the nature of goods to be delivered, the purpose for which they are used, the extent of seller’s knowledge of buyer’s intentions, transportation conditions, the nature of the market and so on.60 A court would look at 1) the course of dealing between the parties; 2) trade usage in the industry; and 3) buyer’s notification to seller of time concerns.61 A purchase order with a definite delivery date can make time of the essence for a material supplier.62
Liquidated Damages
As discussed above in the Introduction, delay damages are often very difficult to prove. The rule that damages must be proven with reasonable certainty63 can mean that it is impossible for a claimant to recover damages, even if it is clear that a claimant has been delayed and has suffered damage. To avoid this difficulty, parties to a construction contract often agree in advance on the damage to be assessed in the event of delay. These “liquidated damages” clauses are normally expressed in a “per diem” or a certain dollar amount per day of delay.
Generally, liquidated damages provisions in a contract are enforceable.64 Parties to a contract may agree in advance about the amount to be paid as compensation for damage, which may result from a delay when the actual damages contemplated at the time of the agreement are uncertain and difficult to determine with exactness and when the amount fixed is in proportion to the probable loss.65 However, when the damages from a breach can be definitely measured or when the agreed amount would be grossly in excess of actual damages, courts usually construe such an agreement to be an unenforceable penalty.66
The fact that a contractor agrees to a contract containing a liquidated damages clause does not prevent that contractor from later litigating the validity of the clause. The party opposing the imposition of liquidated damages is entitled to conduct discovery and present evidence that the damages resulting from breach of the contract are susceptible of definite measurement or that the stipulated damages are grossly in excess of the actual damages suffered. Upon proof of either of these elements, a liquidated damages clause becomes an unenforceable penalty.67
If the party seeking to enforce a liquidated damages provision is responsible for or contributed to the failure to perform, the liquidated damages provision may not be enforceable.68 A party that prevents performance of a contract waives liquidated damages.69 This is true even if the contract requires written notice for extensions of time and the contractor failed to provide the notice.70
The rule is often stated that the damages must be uncertain and in proportion to the probable loss at the time the parties made the agreement. At the same time, however, it seems that a liquidated damages provision will be an unenforceable penalty if damages are certain or out of proportion to actual loss incurred at the time of the dispute. A liquidated damages clause will be an unenforceable penalty when the damage resulting from a breach of contract can be definitely measured or where the liquidated amount is grossly in excess of actual damages.71 Also, if it is apparent that no actual damages were incurred, a liquidated damages provision may be an unenforceable penalty.72
It is possible in a contract to waive the right to claim that a liquidated damages provision is an unenforceable penalty.73
It also is important to remember that a liquidated damage provision can be a double-edged sword. In order to recover, an owner will not need to prove that actual damages were as high as the liquidated amount, but the owner also will be limited to that liquidated amount, even if actual damages were higher. A liquidated damages provision both establishes the amount of damages an owner may claim and limits the contractor’s exposure.74 If a contractor abandons a project, however, this can be a repudiation of the contract, and the owner may not be limited to the liquidated damages in that contract.75
Accordingly, a contractor should review a liquidated damages provision before signing a contract to determine if it is a reasonable amount relative to the actual damage that an owner will incur in the event of delay. If the liquidated amount is low, a contractor should readily agree. If the amount is disproportionately high, the provision may be an unenforceable penalty in a later dispute, requiring the owner to prove actual damage.
Subcontracts often allow a general contractor to pass on to subcontractors any liquidated damages assessed by an owner. Subcontractors would prefer to state that they are liable for liquidated damages only to the extent that their own breach on contract caused any delay. This term appears in the AIA Document A401-1997 (Standard Form of Agreement Between Contractor and Subcontractor). It is common for general contractors to attempt to assess all subcontractors liquidated damages equally or pro rata according to their subcontract amounts.
As discussed above in Claims Procedures, it is important for any contractor to provide notice of any delay caused by others on the project, in order to obtain a time extension, even if no claim for money is allowed or necessary. This is equally true in the case of a liquidated damages clause or the possible assessment of actual delay damage.
No Damage for Delay
AIA Document A201-1997 (General Conditions of the Contract for Construction) expressly allows recovery of delay damages. It states:
8.3. Delay and Extensions of Time
8.3.1 If the Contractor is delayed at any time in the commencement or progress of the Work by an act or neglect of the Owner or Architect, or of an employee of either, or of a separate contractor employed by the Owner, or by changes ordered in the Work, or by labor disputes, fire, unusual delay in deliveries, unavoidable casualties or other causes beyond the Contractor’s control, or by delay authorized by the Owner pending mediation and arbitration, or by other causes which the Architect determines may justify delay, then the Contract Time shall be extended by Change Order for such reasonable time as the Architect may determine.
8.3.2 Claims relating to time shall be made in accordance with applicable provisions of Paragraph 4.3.
8.3.3 This Paragraph 8.3 does not preclude recovery of damages for delay by either party under other provisions of the Contract Documents.
It is certainly possible to waive rights to damages in a contract, if the waiver is express and clear.76 Owners and then general contractors will often require a waiver of delay damages against them. These “no damage for delay” clauses are generally enforceable.77 Such clauses often limit the consequences of delay to a time extension and then only if the contractor provides timely written notice of the delay. Damages resulting from delay will not be allowed in any event. Such a clause may read as follows:
Should the Subcontractor’s performance of this Agreement be directly delayed, hindered, accelerated or disrupted by the Contractor, other Subcontractors or the Contractor’s suppliers, or by any acts or causes of the Owner under the Prime Contract for which the Owner grants the Contractor an extension of time, and the Subcontractor notifies the Contractor in writing within five (5) calendar days after commencement of such delay, inefficiency, loss of productivity, hindrance or disruption as provided in this Article, the Subcontractor will receive an extension of time for the performance of the Subcontractor’s obligations under this agreement. Such time extension will be the Subcontractor’s sole and exclusive remedy, and the Subcontractor will not be entitled to any costs or damages for delay, suspension, inefficiency, loss of productivity, acceleration, disruption, etc., of its work.
Such “no damage for delay” clauses can insulate an owner or general contractor. At the same time, the contractor agreeing to the “no damage for delay” clause can be left exposed to massive damages from delay.
This can lead to very onerous and unfair results. Some states have passed legislation limiting the enforceability of “no damage for delay” clauses, particularly for public procurement.78 Under the Virginia Code, for example, any provision contained in any public construction contract that waives the rights of a contractor to recover damages for unreasonable delay in performing is void and unenforceable as against public policy.79
There are various theories that can allow a contractor claimant to circumvent a “no damage for delay” clause and recover damages. Some of these are described in greater detail in the subsection below on Implied Duties. Some legal theories, however, are peculiar to and used fairly exclusively to avoid no damage for delay clauses.
The theories most frequently used to circumvent a “no damage for delay” clause include the owner’s fraud, bad faith,83 A “no damage for delay” clause will not bar recovery of damages for delays that were not within the contemplation of the parties at the time of the contract.84 A delay also can go on so long that it would be considered an abandonment of the contract, allowing a recovery of damages.85 As discussed below, if the contract has a suspension of work clause, an unreasonable delay also can be considered a suspension of work under that contract clause.
Waiver of Consequential Damages
The types of damage incurred in a contract action include “direct” or “indirect” damages, also called “consequential” damages. Direct damages are those which arise “naturally” or “ordinarily” from a breach of contract. They are damages that can be expected to result from a breach in the ordinary course of human experience. Consequential damages arise from the intervention of “special circumstances” not ordinarily predictable.
If damages are direct, they are compensable. If damages are consequential, they are compensable only if it is determined that the special circumstances were within the “contemplation” of both contracting parties or were “predictable.” Whether damages are direct or consequential is a question of law. Whether special circumstances were within the contemplation of the parties is a question of fact.86
It is often difficult to determine whether damages are direct or consequential. Court case law is sometimes conflicting and confusing. Commonly identified examples of consequential damage, however, would be lost profits or lost opportunities to pursue other business, where no contract yet exists.
It is possible to waive the right to consequential damages in a contract, just as it is possible to waive damages for delay in a “no damage for delay” clause. To avoid confusion, contracts sometimes identify or define direct damages that are recoverable and consequential damages that are not recoverable. AIA Document A201-1997 (General Conditions of the Contract for Construction) states:
4.3.10 Claims for Consequential Damages. The Contractor and Owner waive Claims against each other for consequential damages arising out of or relating to this Contract. This mutual waiver includes:
.1 damages incurred by the Owner for rental expenses, for losses of use, income, profit, financing, business and reputation, and for loss of management or employee productivity or of the services of such persons; and
.2 damages incurred by the Contractor for principal office expenses including the compensation of personnel stationed there, for losses of financing, business and reputation, and for loss of profit except anticipated profit arising directly from the Work
This mutual waiver is applicable, without limitation, to all consequential damages due to either party’s termination in accordance with Article 14. Nothing contained in this Subparagraph 4.3.10 shall be deemed to preclude an award of liquidated direct damages, when applicable, in accordance with the requirements of the Contract Documents.
Note that this contract provision includes a waiver of home office overhead for the contractor, as well as a waiver of lost profits and other projects that may have been impacted by a delay. Similarly, the owner waives rental expenses, financing costs and lost profits that may result from a delay caused by the contractor.
Suspension of Work
Many contracts allow an owner to suspend construction at any time, for the owner’s own convenience, business or other economic reasons. Depending upon the contract terms, a suspension of the work by the owner normally results in a claim for additional time and money from the contractor.
AIA Document A201-1997 (General Conditions of the Contract for Construction) states:
14.3 SUSPENSION BY THE OWNER FOR CONVENIENCE
14.3.1 The Owner may, without cause, order the Contractor in writing to suspend, delay or interrupt the Work in whole or in part for such period of time as the Owner may determine.
14.3.2 The Contract Sum and Contract Time shall be adjusted for increases in the cost and time caused by suspension, delay or interruption as described in Subparagraph 14.3.1. Adjustment of the Contract Sum shall include profit. No adjustment shall be made to the extent:
.1 that performance is, was or would have been so suspended, delayed or interrupted by another cause for which the Contractor is responsible; or
.2 that an equitable adjustment is made or denied under another provision of the Contract.
Note that the AIA suspension of work clause does call for an adjustment of the contract sum, including profit. In a U.S. government contract, the federal acquisition regulations contain a suspension of work clause allowing the government to suspend work, but expressly excluding profit to the contractor in any claim.87
Just as the changes clause in a contract is used to make a claim for a “constructive change,” a suspension clause in a contract is sometimes used to make a claim for a “constructive suspension” when delays occur.88
Implied Duties and Other Legal Theories
Many breach of contract theories have been allowed by courts based on “implied duties” not explicitly in the contract. These breach of implied duty theories are often used to circumvent a “no damage for delay” clause, but also are used to claim compensation for costs incurred due to other types of constructive changes.89 By definition, an implied duties theory is used when there is no express provision in the contract allowing the claim or there is an express provision disallowing this type of claim. Please also see the subsection below on Fact Supporting a Claim for related concepts.
Claimants and courts are often “stretching” contract terms or the law in order to avoid an obviously unfair result. Most of these cases involve some element of bad faith or act of interference with the claimant. The names placed on these implied duties by courts and commentators vary, with some similarities, redundancies and confusion. A non-exhaustive list would include the following:
Prevention of a Condition Precedent
or Implied Duty Not to
Prevent Occurrence of Condition Precedent90
If a contract contains a “condition precedent,” one party to the contract cannot prevent occurrence of the condition precedent and then take advantage of the nonoccurrence to excuse performance. For example, in a “pay if paid” clause, payment from the owner is a condition precedent to the general contractor’s obligation to pay the subcontractors.
The prevention doctrine is a generally recognized principle of contract law. If a promisor prevents or hinders fulfillment of a condition to his performance, the condition may be waived or excused.91 The prevention doctrine does not require proof that the condition would have occurred “but for” the wrongful conduct of the promisor. Instead, it only requires that the conduct have “contributed materially” to the non-occurrence of the condition. It is as effective an excuse of performance of a condition that the promisor has hindered performance as that he has actually prevented it.92
Implied Duty Not to Actively Interfere with Performance93
Implied Duty Not to Hinder or Delay Performance94
These concepts include an Implied Duty to provide necessary working conditions for performance96
Implied Duty Not to Prevent Performance97
An implied provision of every contract is that neither party to the contract will do anything to prevent performance thereof by the other party or commit any act that will hinder or delay performance. Such hindrance of performance can amount to a substantial breach of the contract.98 A breach of this duty can result in delay damages and costs incurred because work was hindered, including extra manpower costs.99
A party to a contract who wrongfully hinders or prevents the other party from performing his obligations under a contract has breached the contract. This implied condition is founded upon the principle that he who prevents a thing from happening cannot take advantage of the nonperformance he caused. The principle does not apply when the hindrance is due to action which he is permitted to take under the terms of the contract.100
Implied Duty to Adequately Coordinate Work of Subcontractors101
Implied Duty to Provide Adequate Supervision102
Implied Duty to Carry Out Bargain Reasonably and in Good Faith103
It would be intolerable if the government could disregard the responsibility to carry out its bargain reasonably and in good faith, or were free to stretch its tardiness for however long it fancied, without sterner control than the mere prolongation of the completion date of the contract.104
Implied Duty to Cooperate105
It is an implied provision of every contract that the other party promises to co-operate and failure to do so is a breach. Where this implied provision is breached by delay, the other party is entitled to recover the additional expenses.106
Implied Warranty of Plans and Specifications107
As discussed in detail in the prior subsection, when the owner provides the plans and specifications, it implicitly warrants that compliance with the specifications will result in satisfactory performance.108
When a general contractor supplies a subcontractor with plans prepared by the owner’s design professional, the general contractor impliedly warrants those plans to the subcontractor. Absent open and obvious design defects, which should be apparent to a prudent contractor and called to a prime contractor’s attention, the party who furnished plans and specifications impliedly warrants them to be fit for their intended use.109

Please also see the subsection above on Implied Duties and Other Legal Theories for related concepts.
Failure to Cooperate110
Every contract has an implied promise to cooperate and failure to do so is a breach. Where this implied provision is breached by delay, the other party is entitled to recover the additional expenses.111
Failure to Provide Necessary Working Conditions for Performance112
Failure to Adequately Coordinate Work of Subcontractors113
Failure to Adequately Provide Adequate Supervision114
Failure to Provide Adequate Supervision, Incompetent Supervisors and Frequent Change of Supervisors115
Excessive Changes So Beyond Scope as to Breach Contract116
Changes ordered can go so beyond the scope of the contract, including the changes provisions, as to breach the contract. The cumulative effect of numerous change orders can result in a claim for the resultant disruptions and inefficiencies in a contractor’s construction operations.117
Defects in Plans or Specifications
The owner also is responsible for delays caused by faulty plans and specifications, including the failure to recognize the need for revisions in the plans and failure to make those revisions in a timely manner.118
Interference and Hindrance from Design Professionals
Contradictory instructions and failure to give instructions by a design professional can amount to hindrance or active interference that is a breach of contract by a project owner.119 The architect is the agent for the owner, and the owner is responsible for any damages caused by the architect’s deficiencies, including delays and inefficiencies.120
Failure to Return Shop Drawings within a Reasonable Time121
Failure to Provide Samples for Manufacture of Materials122
Substantial Completion
AIA Document A201-1997 (General Conditions of the Contract for Construction) states:
9.8 Substantial Completion
9.8.1 Substantial Completion is the stage in the progress of the Work when the Work or designated portion thereof is sufficiently complete in accordance with the Contract Documents so that the Owner can occupy or utilize the Work for its intended use.
It is generally true that once the Owner has actually occupied the project, the contractor has achieved substantial completion. This depends upon the terms of the contract, however. Certification of the architect can particularly be an issue.123
Substantial completion is significant, because any claim for liquidated damages will normally end or be reduced once substantial completion is achieved.124
Substantial Performance
A related concept is substantial performance, which can allow a contractor to recover for labor and material provided, even if the contractor has not completely complied with all terms of the contract. Substantial performance is an “equitable” concept, relieving a contractor of the strict legal terms of the contract to prevent “forfeiture” by the contractor or “unjust enrichment” by the owner.125
A contractor is still liable for damages cause by its failure to completely comply with the contract, but can avoid a complete forfeiture and can recover some value of the labor and material supplied.
Impossibility
Impossibility can be a defense to delay or other damages for breach on contract. Impossibility or impracticability may not be subjective but must be objective. The difference between the two concepts has been summarized in the phrases “the thing cannot be done” (objective impossibility or impracticability) and “I cannot do it” (subjective impossibility or impracticability).126
If performance is rendered merely difficult or burdensome or unprofitable, the breach of contract is not excused. Successful completion of a portion of the work proves that it was feasible to perform all work to the contract requirements.127
Excusable Delays
There is a distinction between delays that are “excusable” or “inexcusable” and delays that are “compensable” or “non-compensable.”
Whether a delay is excusable determines whether the contractor is entitled to an extension of time. An extension of time normally protects a contractor from liquidated damages or actual damages from the owner for delay.
Whether a delay is excusable depends initially on the contract terms discussed above.128 Most contracts provide a specific delivery schedule. This will leave the contractor in default and liable for delay damages if the completion date is not met and the delays are not excusable. However, a time extension clause in a contract does not necessarily provide an exemption from damages for delay.129
Most construction contracts will state that “Time is of the Essence.” This means what it says in a construction contract. If there is no “excusable delay” or “force majeure” term in the contract, a time is of the essence clause can mean a contractor is liable for damages in the event of delay, even if the contractor did not cause the delay.130 An excusable delay or force majeure term states that a contractor is not responsible for delays from causes beyond the contractor’s control.131 In order to obtain even a time extension under a force majeure clause, the contractor usually must prove that the delay was truly beyond the contractor’s control and that the delay was unexpected, unusual or out of the ordinary. Unforeseeablity is often a difficult element to establish, particularly when delay is caused by a subcontractor or supplier.132
A force majeure clause only entitles a contractor to a time extension. The contractor is protected from liquidated damage or actual damages for delay beyond the contractor’s control. The contractor’s affirmative claim for compensation for the delay will be controlled by other contract provisions.
Examples of excusable (but non-compensable delays) would be extraordinarily adverse weather, labor strikes, or lack of sole source materials. Owner-caused delays also are excusable (but may not be compensable, depending on contract terms133), including design defects, change orders, suspension of work, lack of permits, rights of way or access to the site or over inspection. Differing site conditions or impossibility also can result in excusable delays.
Weather
Weather conditions are normally out of a contractor’s control. However, weather conditions are often “foreseeable” and inexcusable.
If extensions of time are authorized only for “adverse weather conditions not reasonably anticipated,” a contractor must be ready to prove that the adverse weather conditions were extraordinary.134
A contractor also has a duty to mitigate the effects of adverse weather conditions. Examples could be covering or heating work areas. A contractor should drain work areas promptly after precipitation to reduce surface water or muddy conditions. The failure to mitigate the effect of adverse weather conditions can limit the length of excusable delay.135
Compensable v. Non-Compensable Delays
There is a distinction between delays that are “excusable” or “inexcusable” and delays that are “compensable” or “non-compensable.”
If a delay is “compensable,” the contractor is entitled to an extension of time and additional money as compensation for the delay. In general terms, a delay is compensable to a contractor only if the delay is caused by the owner (or the owner’s agents) and the claimant has not waived its right to compensation in the contract. A contractor can waive their right to compensation for owner caused delay in a “no damage for delay” clause or waiver of consequential damages.136
Concurrent Delay
When there are two causes for the same delay at the same time, the delay is “concurrent.” A concurrent delay can be any combination of excusable, inexcusable, compensable and non-compensable delays. The battle normally revolves around whether a contractor is entitled to an extension of time or compensation, when the contractor has contributed in some manner to the delay. In other words, concurrent delay is most often used as a defense to a delay claim.
The treatment of concurrent delays is inconsistent and is, therefore, unpredictable. It also probably is evolving over time.
The traditional approach was for courts to refuse to apportion delays. Where the causes of delay were mutual, the courts would not allow compensation against a contractor but also would refuse to grant liquidated or other damages to the owner.137 In the case of concurrent delays, the contractor is entitled to a time extension but not additional money. In other words, neither party could recover from the other.138 This rule still seems to be consistently applied if the causes of the delay are too interrelated to apportion fault.139
Courts have been increasingly willing to apportion fault for delay and damages.140 This is probably in part because the science of construction scheduling has developed to the point that the evidence of delay is more reliable. If there is adequate evidence to apportion the delay, courts may allow proportional recovery.141 Some contract terms define what weather conditions are reasonable and foreseeable.
It also is becoming increasingly common for contract documents to allocate these risks and determine the result of concurrent excusable or inexcusable or compensable and non-compensable delays.
Acceleration
The owner will typically have the right to change the contract schedule and “accelerate” the work. A “directed acceleration” would be by formal change order.
Allowable acceleration costs would include all costs incurred to accelerate performance that the contractor can prove with reasonable certainty, including additional labor or overtime charges for labor; additional or increased supervision; additional subcontractors; and accelerated freight or delivery charges as well as inefficiency costs from overtime and extended labor hours, out-of-sequence work, crowding or stacking of trades.
Constructive Acceleration
A “constructive acceleration” is essentially an acceleration to the contract schedule that is not “directed” or recognized by the owner. To have a constructive acceleration, the contractor must face an excusable delay and properly request an extension of time for that excusable delay, which is refused by the owner. As a result, the contractor is essentially required by the owner to complete work in less time than allowed by the contract.
In order to be successful in a constructive acceleration claim based upon an owner’s failure to grant time extensions for excusable delays, three conditions must be established: (1) that any delays giving rise to the orders were excusable; (2) that the contractor was ordered to accelerate (achieve the unextended contract completion date); and (3) that the contractor in fact accelerated performance and incurred extra costs.142 It is advisable for a claimant to send the owner a notice of intent to accelerate, with a reservation of rights to claim the costs of acceleration.
It is important to make a proper request for an extension of time in accordance with the contract. AIA Document A201-1997 (General Conditions of the Contract for Construction) states:
4.3 Claims and Disputes
4.3.1 Definition. A Claim is a demand or assertion by one of the parties seeking, as a matter of right, adjustment or interpretation of Contract terms, payment of money, extension of time or other relief with respect to the terms of the Contract. The term “Claim” also includes other disputes and matters in question between the Owner and Contractor arising out of or relating to the Contract. Claims must be initiated by written notice. The responsibility to substantiate Claims shall rest with the party making the Claim.
4.3.2 Time Limits on Claims. Claims by either party must be initiated within 21 days after occurrence of the event giving rise to such Claim or within 21 days after the claimant first recognizes the condition giving rise to the Claim, whichever is later. Claims must be initiated by written notice to the Architect and the other party.
Claims for Additional Time
If the Contractor wishes to make Claim for an increase in the Contract Time, written notice as provided herein shall be given. The Contractor’s Claim shall include an estimate of cost and of probable effect of delay on progress of the Work. In the case of a continuing delay only one Claim is necessary.
Acceleration costs are the additional costs incurred by a contractor to overcome excusable delays, including costs caused by the addition of extensive modifications to the work, within the time limits originally established in the contract. Acceleration costs can include costs paid for multiple shift operations and other increased operating expenses related to performance of the work on an accelerated time schedule.143
Impact Costs
Impact costs are increased costs attributed to the cumulative effect of numerous modifications on one another and on the original contract work and to the resultant disruptions and inefficiencies in a contractor’s construction operations.144
Right to Finish Early
It is possible to get delay damages, even if a project is completed on time or early. Although the owner is not under a duty to help the contractor complete the contract early, the owner may not deliberately prevent the contractor from completing its contract ahead of time. Where an owner is guilty of “deliberate harassment and dilatory tactics” and a contractor suffers damages as a result of such action, defendant is liable for breach of contract.145 The contractor has to show that it could have finished the contract work early and would have done so, but was prevented by the delay caused by the owner.146 The contractor also must show some type of interference or hindrance from the owner.147
Claims Under Mechanic’s Liens and Bonds
Mechanics liens and bonds are devices to secure and enforce payment.148 The ability to collect under mechanics' liens and bonds for lost profit, delay or other claims is often in question, however, depending upon the wording of any particular statute or court case law interpreting the statute.
Payment bonds are “for the protection of all persons supplying labor and material in carrying out the work.”150 and other constructive changes are recoverable as costs of providing labor and material to the project.151 Under some state Little Miller Acts, however, damages for delay are not recoverable against a bond.152 Lost profits caused by delay are not out-of-pocket expenditures for “labor and material” and consequently are not recoverable under the federal Miller Act and most state bonding laws.153
Recovery of claims in a mechanic’s lien will depend upon the wording of each state mechanic’s lien statute and the court case law. Many mechanic’s lien statutes provide a lien “for labor or material provided for the construction of an improvement” or similar language. Many courts have concluded that delay claims, lost profits or other “off-site” claims are not labor or material provided for the construction of an improvement.
Experts
Claims cases typically involve much use of expert testimony. In any claim case, an expert is helpful or necessary to prove the proper amount of damages. In delay cases, scheduling experts also are usually necessary to prove liability or the causes of delay.
Experts will add greatly to the cost of litigation. Experts will charge hundreds of dollars per hour. Your attorney also must spend many hours evaluating the expert testimony and other evidence in the case. It is possible for client witnesses to qualify as “experts,” and this has the potential to save money in a simple or low dollar value case. Client witnesses are not usually true experts, however. The subject matter is often beyond their expertise. Opposing experts and attorney will be able to highlight these shortcomings.
A trial judge acts as the “gate-keeper” to determine the admissibility of an expert’s testimony. The factors a judge will consider include whether a theory or technique can be (and has been) tested; whether it has been subjected to peer review and publication; whether a particular technique has a high known or potential rate of error and whether there are standards controlling the technique’s operation; and whether the theory or technique enjoys general acceptance within a relevant scientific community.154
In claims cases, expert testimony is generally admissible if it will assist the judge or jury in understanding the evidence. However, the evidence must be based on an adequate foundation.155 Expert testimony is not admissible if it is speculative or founded on assumptions that have an insufficient factual basis.156 Testimony also is inadmissible when an expert has failed to consider all variables bearing on the facts observed.157
It is probably true that courts have become more careful with and critical of expert testimony, as the science of delays and other damages has improved and expert testimony becomes more common. The trial judge must ensure that any and all scientific testimony or evidence admitted is not only relevant but reliable. The trial judge must determine at the outset whether the expert is proposing to testify to scientific knowledge that will assist the judge or jury to understand or determine a fact in issue. This includes a preliminary assessment of whether the reasoning or methodology underlying the testimony is scientifically valid and of whether that reasoning or methodology properly can be applied to the facts in issue.
Ordinarily, a key question in determining whether a theory or technique is scientific knowledge will be whether it can be (and has been) tested. Scientific methodology today is based on generating hypotheses and testing them to see if they can be falsified. This methodology is what distinguishes science from other fields of human inquiry. Another consideration is whether the theory or technique has been subjected to peer review and publication. Publication (which is one element of peer review) does not necessarily establish reliability. In some instances, well-grounded but innovative theories have not been published. Some propositions are too particular, too new or of too limited interest to be published. But submission to the scrutiny of the scientific community is a component of “good science,” in part because it increases the likelihood that substantive flaws in methodology will be detected. For purposes of determining whether a theory or technique is scientific knowledge, the court ordinarily should consider the known or potential rate of error, and the existence and maintenance of standards controlling the technique’s operation.158
Critical Path Method
The critical path can be defined as the series of activities with the longest extended duration representing the shortest time within which the project can be completed if the construction proceeds as planned. Any one day of delay in a critical path activity will delay the completion of the project by one day.
A schedule normally shows “activities” and “durations” for ea
