Construction Law 2026 Comparisons

In the United States, construction is not governed by a single, unified source of law. Instead, the laws governing construction vary depending on whether the project is federal or supported by federal funding, or whether the project is located within a particular state and locality or supported by state of local funds. 

Some federal laws apply to construction nationally, including at the state and local levels, particularly in areas such as workplace safety, procurement and environmental compliance, such as the federal Occupational Safety and Health Act (OSHA), the Clean Water Act, the Clean Air Act and the Americans with Disabilities Act. Federal regulations applicable to construction may be found in the Code of Federal Regulations. The Federal Acquisition Regulations (FAR) contained in Title 48 of the CFR provide the primary set of rules and regulations governing how the federal government purchases goods and services, including construction projects.

State law, however, provides the principal legal framework for the construction market. Core issues – including contractor licensing, mechanic’s liens, construction defect liability, and most contract enforcement – are governed by state statutes and common law. These laws vary materially by jurisdiction and are often compiled or referenced through resources such as the AGC/ABA Construction State Law Matrix (available at AGC Construction State Law Matrix). 

Local governments add a further layer of regulation through zoning ordinances, permitting requirements and code enforcement, which directly control land use, building design and project approvals. This local overlay is often determinative in day-to-day project execution, particularly for entitlement and inspection processes.

A significant distinction regarding the use of contract forms is whether the construction is public or private in nature. For public works projects, federal, state and local agencies often use their own forms of contracts for construction and to structure their contracts with design professionals. 

In private projects, standard-form construction contracts are widely used to structure project relationships, although they are not mandated by law. The most common are those published by the American Institute of Architects (AIA), including A101 (owner–contractor), A201 (general conditions), B101 (owner–architect) and A401 (contractor–subcontractor). Other frequently used forms include those from ConsensusDocs, which are often selected for their more neutral risk allocation, and the Engineers Joint Contract Documents Committee (EJCDC), particularly on infrastructure and engineering-heavy projects. International forms such as FIDIC or NEC are rarely used in purely domestic projects but may appear where foreign owners, lenders or contractors are involved.

In design-build and EPC arrangements, parties often adapt or heavily amend standard forms – or use hybrid agreements – to consolidate design and construction responsibilities under a single entity.

The common terminology in the US for the party that owns or sponsors a construction project is the “owner” or “developer”, whereas in international settings these parties may be called the “employer”. Regardless of terminology, the role of the owner or developer is to initiate, define, finance and ultimately own and benefit from the construction project. The identity of the owner depends primarily on the nature of the project:  private, public or hybrid.

In the private sector, owners are commonly real estate developers, corporate end users, or investment-backed entities. Public projects are usually commissioned by federal, state or local government agencies and are subject to procurement laws and rules, competitive bidding requirements and fiscal controls. A growing third category involves hybrid structures, particularly public-private partnerships (P3s), where a public entity contracts with a private consortium that assumes many traditional owner functions.

The critical common denominator is the establishment of a contractual relationship between the owner/developer and a general contractor. The general contractor is responsible for co-ordinating and executing the work, including hiring subcontractors for specialised trades. 

The “contractor” on a construction project is typically a licensed general contractor, design-builder, engineering, procurement and construction contractor (EPC), construction manager-at-risk (CMAR), joint venture or specialty trade contractor, depending on the project structure and delivery model. Contractors and subcontractors must maintain adequate licensure under applicable state law for the work they undertake. 

The “employer” is referred to in the United States as the owner, developer, public agency or project sponsor. Its principal rights are to receive the work required by the contract, enforce schedule and quality obligations, direct changes through the contract’s change-order mechanism, reject non-conforming work, require correction of defective work, enforce warranty, insurance and bonding requirements, withhold retainage and terminate the contract for default or convenience, depending on what contractual grounds for termination exist. The owner’s principal obligations are to pay properly earned amounts, provide access to the site, furnish owner-supplied information or designs where applicable, make timely decisions and approvals, refrain from interfering with the contractor’s performance, and comply with statutory prompt-payment and withholding requirements. 

Where the owner furnishes the design, the owner also generally carries an implied warranty of the correctness and sufficiency of the plans and specifications. Design responsibility otherwise depends heavily on the delivery model. In traditional design-bid-build delivery, the owner typically retains the designer and provides the plans and specifications, while the contractor is generally responsible for building in accordance with those documents, subject to duties to identify conflicts or obvious deficiencies. In design-build delivery, the design-builder assumes integrated responsibility for both design and construction, typically through an architect or engineer of record and supporting design consultants. 

Financiers generally sit outside the construction chain, but their practical influence can be significant. Traditional construction lenders, bondholders, private equity sponsors, public funding agencies and concession lenders usually derive their rights from loan documents, security instruments, assignments, collateral agreements, completion covenants and direct agreements that may provide notice, cure, consent or step-in rights. That influence is increasingly pronounced in public-private partnership (P3) projects, where lenders often have substantial oversight over project milestones, defaults, replacement contractors, cure periods and major contract amendments.

In US construction practice, subcontractors are typically trade specialists rather than general building contractors. Common examples include electrical, plumbing, HVAC, framing, drywall, roofing, concrete, excavation, fire protection, landscaping and waterproofing contractors, each responsible for a discrete scope of work co-ordinated by the general contractor. On larger or more complex projects, subcontractors may also include specialty design-build entities, as well as suppliers and fabricators that provide both labour and materials for defined portions of the work.

A subcontractor’s principal rights and obligations arise under its subcontract. That agreement governs scope, price, schedule and risk allocation. In addition, US construction law generally provides statutory payment protections and imposes procedural requirements that subcontractors must follow to preserve their remedies. If unpaid, subcontractors may have access to a range of remedies, including mechanic’s liens on private projects, claims against payment bonds on public or bonded projects and, in some jurisdictions, stop payment or fund-trapping notices directed to upstream parties.

Primary financing institutions for private construction projects include commercial banks and specialised construction lenders, alongside institutional investors such as pension funds and real estate investment trusts (REITs). For public projects, financing typically comes through municipal bonds, federal grants or state infrastructure funds.

In the United States, the “designer” role is performed by licensed architects and engineers. State professional licensing laws regulate both architectural and engineering services. On larger or more complex projects, particularly in infrastructure or industrial settings, design responsibilities may also be undertaken by design-build contractors or integrated project delivery teams, where the designer is contractually aligned with the builder rather than directly with the owner.

Designers must perform their services with the level of care and skill ordinarily exercised by members of the profession under similar circumstances (the “standard of care”). Typical designer duties include preparing plans and specifications, co-ordinating with consultants, assisting with permitting and providing limited construction administration services (eg, submittal review, site observations).

The contractual relationship with the designer depends on the project delivery method. In the traditional “design-bid-build” model, the designer contracts directly with the owner, and the contractor separately contracts with the owner; there is no direct contractual relationship between designer and contractor. In design-build arrangements, the designer is often retained by the contractor, shifting risk and contractual privity accordingly. Across all models, disputes frequently arise over alleged design deficiencies, co-ordination gaps or scope ambiguities.

The “scope of the works” is determined principally by the contract documents read as an integrated whole, rather than by a single “scope” clause. Those documents typically include the agreement, general and supplementary conditions, drawings, technical specifications, addenda, schedule or schedules, geotechnical and survey information, permit requirements, quality-control requirements, testing and commissioning obligations and any incorporated owner criteria. The central organising principle is that the owner defines the required result, but the contractor and its subcontractors generally remain responsible for the means, methods, techniques, sequences, procedures and safety precautions used to perform the work, unless the contract expressly shifts or constrains that responsibility.

Specifications can be prescriptive, performance-based or a combination of both, depending on the procurement model, contract documents and governing laws. Prescriptive specifications tell the contractor the materials, dimensions, equipment, systems or installation requirements to use. Performance specifications state the required result – ie, capacity, durability, output, efficiency, code compliance, availability, lifecycle performance or other measurable criteria – and leave greater responsibility with the contractor, design-builder, EPC contractor or delegated-design subcontractor to determine how to achieve that result. 

Variations and changes are usually governed by the construction contract rather than by statute, with state law supplying general contract rules and public policy limits where applicable. Variations are usually addressed as a change order, construction change directive, field order or similar written modification that adjusts scope, price and, where warranted, time. Thus, the practical answer in most states is that the parties’ agreed procedures largely control how a variation or change is requested, priced, approved and challenged.

When the owner requests a variation or change, the scope is determined by reference to the original contract documents (drawings, specifications, bill of quantities, schedule of values), and is usually limited to genuine additions, deletions or modifications to that agreed scope rather than a wholesale reallocation of risk or unrelated betterment. Pricing is then addressed by applying existing contract unit rates where they are applicable, deriving or adjusting rates where necessary or, failing that, negotiating new unit rates or time and materials with stated mark-ups and any contractual caps or exclusions on particular cost categories.

When the contractor initiates a variation (for example, due to differing site conditions, design defects, owner interference or regulatory changes), contracts typically require prompt written notice of claim, followed by a priced proposal using the same valuation hierarchy (contract rates first, then derived rates or negotiated time and materials) and subject to the same contractual limitations on recoverable cost categories. The contractor bears the burden to demonstrate entitlement under the relevant change, differing site condition or claims provisions, and to prove cost and time impact using contemporaneous cost records and CPM based schedule analysis.

Contractors are typically liable to owners for liquidated damages in a per diem amount stated in the contract for delays contractors’ cause. When the owner is responsible for delays, then the contractor is entitled to be paid for delay costs. Often, the contractor must support its claim with a time impact analysis against the approved schedule to justify any extension of time. Disputes over the number of days of delay and the daily rate for time related costs are common. Time-related costs are also known as extended overhead costs, and can include field overhead, site supervision and, in some cases, home office overhead and escalation. 

Responsibilities during the design process follow three main delivery models that differently allocate design responsibilities. In the traditional design-bid-build approach, the owner contracts separately with the designer for complete plans and specifications, then separately with the contractor for construction. In design-build delivery, the design and construction responsibility lie with a single entity (the design-builder), through which the design-builder either has in-house design services or teams with a design firm to provide the design. The owner provides input through design review and approval. Under a third model, the owner contracts with the designer for the design and separately with a construction manager provides pre-construction review of the design as it progresses, such as constructability and schedule reviews and cost.  The construction manager provides early and ongoing input to reduce the cost and increase the efficiency of the work, and then contracts with the owner to serve as the construction contractor.

Traditional design-bid-build arrangements represent one of the most common project delivery methods. The owner/employer retains architects and engineers to design the project, then separately contracts with a general contractor for construction. The owner bears primary responsibility for design adequacy and securing permits, financing and insurance, while maintaining ultimate control over project specifications and changes. The general contractor assumes responsibility for means and methods of construction, safety compliance, scheduling and co-ordinating all construction activities. Subcontractors typically contract directly with the general contractor (not the owner) and bear responsibility for their specific trades while remaining subject to the general contractor’s overall project management and safety oversight.

Design-build delivery consolidates design and construction responsibilities under a single entity, shifting significant risk allocation. The design-build contractor assumes responsibility for both design adequacy and construction performance, often reducing the owner’s exposure to design-related delays and cost overruns. The owner provides input through design review and approval. Progress design-build contracting has become more prominent on public projects as contractors on large projects have found design-build contracting unprofitable. The progress design-build methodology retains design-build characteristics but uses a two-phase approach in which the construction contract is not negotiated until the design has been reached.

The owner is usually responsible for providing accurate information about the site (including known pollution, underground utilities or obstacles, geotechnical data, such as soil conditions, and any known archaeological sensitivities), while the contractor is responsible for visiting the site, reviewing the provided information, investigating subsurface conditions and alerting the owner to any discrepancies they reasonably discover. Responsibility for the condition of a construction site is primarily set by contract, but subject to certain responsibilities imposed by mandatory or regulatory law that cannot be fully disclaimed.

Typically, agreements include a “differing site conditions” clause where the owner bears the risk of concealed or unknown conditions that materially differ from those indicated in the contract or that are unusual and could not be reasonably anticipated. Such differing site conditions may include unexpected contaminated soil, unmapped utilities, unusual rock formations or archaeological artifacts. The differing site condition would then be handled through the contractual change order and time/cost adjustment process.

Construction projects are usually subject to permitting requirements on the federal, state and/or local levels, depending on the project. At the federal level, the most significant mandatory permits include National Pollutant Discharge Elimination System (NPDES) stormwater permits under the Clean Water Act, water quality certifications, Clean Air Act pre-construction permits and workplace safety compliance under OSHA’s construction standards. At the state and local levels, the principal permit categories include building permit(s), zoning/land use approvals and certificates of occupancy.

Responsibility for obtaining permits is primarily allocated by mandatory regulatory law (state contractor licensing statutes and local building codes) but is routinely further defined and allocated by the construction contract between the parties. Under both statutes and industry standards, the general contractor is typically responsible for obtaining local building and trade permits, while environmental permits are generally sought by the project owner or developer. Contractual allocations are enforceable between the parties but do not eliminate the underlying regulatory obligations imposed by statute.

Maintenance obligations are primarily defined by contract rather than by mandatory law. Typically, the contractor is responsible for maintaining the work and protecting it from damage until substantial completion, which is the point when the owner can use the project for its intended purpose. After substantial completion (and certainly after final completion), day-to-day maintenance typically shifts to the owner or eventual operator. During the warranty period (often one year, but it can vary), the contractor must correct defective work, but is not usually responsible for routine upkeep unless the contract says otherwise. On federal construction projects, the Federal Acquisition Regulation (FAR) clauses commonly used in fixed-price construction generally put maintenance, custody and risk on the contractor until acceptance, with warranty responsibilities continued as stated in the contract.

The financing or borrowing requirements in a construction project depend on the circumstances. In public works, the government agency would not use bank financing to fund the construction. The government agency, however, may have issued general or project-specific bonds that provide the capital to fund the work. The contractor would typically rely on periodic payments from the government agency, and its own capital resources, to provide the necessary capital and cash flow.

In private projects, it would be common for the owner or developer to use construction loan financing. Construction loans are a specialised field of property financing generally subject to rigorous bank reviews and approvals for disbursement of funds. Lenders require developed budgets, schedules and risk assessments at the outset, and impose tighter controls during construction through draw procedures tied to progress, documentation and lien compliance.       

The completion testing process typically follows a structured sequence beginning with contractor self-inspection and trade-specific testing by subcontractors, followed by third-party commissioning for complex systems and concluding with owner acceptance inspections. Building code compliance testing occurs throughout construction via mandatory municipal inspections for electrical, plumbing, structural and fire safety systems, while performance testing of HVAC, elevators, fire suppression and other building systems typically occurs during the final phases before substantial completion.

Completion, takeover and delivery operate as distinct but interrelated processes. Completion consists of the progression from substantial completion of a project, the point at which the owner can use the project for its intended purpose, to final completion, when all contractual obligations are fulfilled by the contractor. Takeover consists either of the owner’s voluntary assumption of beneficial occupancy at or after substantial completion or a forced takeover by the government or a surety following a contractor’s default. Delivery describes the contractual framework under which a project is brought to fruition, such as design-build.

A contractor’s liability for defects is generally governed by a combination of contract terms and state statutes of limitation and repose, so there is no single national defects liability period. Commercial construction contracts commonly include a short contractual correction or warranty period, often one year from substantial completion, during which the contractor must correct defective work after notice, but that contractual period usually does not replace the longer period in which the owner may bring a formal claim under applicable state law. Using California as an example, latent construction defect claims are generally subject to a ten-year statute of repose under Code of Civil Procedure § 337.15 running from substantial completion, which functions as an outside deadline. 

In some states, there are also mandatory notice rules that require an owner to serve written notice of alleged construction defects and provide the contractor with a pre-suit opportunity to inspect, offer to repair or otherwise cure the claimed defects before a lawsuit can proceed, with statutory timelines and consequences if those procedures are not followed. For example, for construction defect claims governed by California’s SB 800 (Right to Repair Act), where the builder has properly elected the statutory procedures, the homeowner must serve written notice of the alleged defects and follow the Act’s specified pre litigation process before filing suit, including giving the builder opportunities for acknowledgment, inspection and repair.

Pricing for construction contract prices is usually based on one of two primary approaches: fixed pricing and cost-plus pricing. Fixed price contracting involves payment of a stipulated sum by which the contractor agrees to complete the work for a set amount. Government construction projects are subject to competitive bidding laws and regulations, which often require contractors to provide fixed-price bids.

Cost-plus pricing involves paying the contractor for the costs of the work plus a management or overhead fee. Cost-plus pricing is used in private contracting. The cost of the work may reflect the actual costs of labour and materials, or may be based on unit pricing particularly on civil and infrastructure projects, where payment is tied to measured quantities (eg, per cubic yard or linear foot). Notably, “cost plus a percentage of cost” pricing is unlawful on federal construction projects. Cost-based pricing often is used when the scope of work is not well defined, although a common arrangement includes a guaranteed maximum price (GMP), which caps the owner’s financial exposure while allowing some flexibility in design development. The choice of pricing method typically reflects the level of design completeness and the parties’ appetite for risk allocation.

Price indexation is not typical in US construction contracts. In a fixed-price or lump-sum contract, the contractor provides the owner with a total price for completing all elements of the project. Under this method, the contractor bears the risk of cost increases, as the contractor is forced to absorb any losses due to increases in material prices. In addition, most contracts will have a force majeure clause, which may open the door for contractors to claim that price increases caused by such events are not their responsibility. Such claims were made with varying success due to COVID-19 era disruptions.

In other types of contracts, the owner may bear the risk of price escalation. When a contractor works on a “cost-plus” or “cost-reimbursable” basis, the owner pays for the actual costs of performing which would include price increases during the work. Price escalation is not paid through an index, however, but simply passed on to the owner as the actual cost of the work. 

In most construction projects, the timing and conditions for payment are established by the contract, with statutory prompt payment provisions requiring timely payments. There are two typical contractual methods for the timing of payments, based either on regular interim payments (usually monthly) and calculated using the “percentage complete” of the work, or delayed payments based on achieving specified “milestones.” Contracts typically require the contractor to submit payment application requests supported by details on the work performed, which the owner must review, adjust and approve. Retention (typically 5% to 10%) is commonly withheld by the owner to incentivise completion and protection against defective work. 

At the federal level, projects involving the federal government are subject to the Prompt Payment Act, which sets payment deadlines and requires interest on late payments. Federal construction contracts are also governed by the Miller Act, which affords subcontractors and suppliers the right to pursue claims against payment bonds in lieu of mechanic’s liens. In addition, “pay-when-paid” and “pay-if-paid” provisions are often used in subcontracts to allocate payment risk, although their enforceability varies by jurisdiction and may be limited by statute or public policy. Overall, interim payments are the norm, advance payments are more limited and payment risk is managed through a combination of contractual and statutory protections.

Construction contracts employ several distinct invoicing and payment application methods, each tied to the underlying contract pricing structure. Some of the most common means of invoicing in construction contracts are: (i) progress payment applications tied to a schedule of values (SOV), used predominantly in lump sum/fixed-price contracts; (ii) unit-price billing based on actual quantities of work performed; (iii) cost-plus or time-and-materials (T&M) invoicing supported by detailed cost documentation; (iv) milestone-based billing triggered by completion of defined project phases; and (v) final payment applications submitted upon project close-out.

Additionally, most states have prompt payment acts that govern what constitutes a proper or complete invoice and the timing of owner payment obligations once a compliant payment application is submitted.

Project planning starts with the owner or developer establishing the overarching constraints including the project boundaries, access, the time to complete construction and interim milestone dates. These requirements are packaged into the construction contract entered into with the general contractor.

The contractor is generally responsible for preparing a baseline schedule, often using the critical path method (CPM), showing the sequencing, duration and interdependence of activities, along with key milestone dates.

Delay claims typically begin with formal notice requirements mandated by most construction contracts, requiring the contractor to provide written notice within specified timeframes detailing the cause, expected duration and requested relief. Critical path method (CPM) scheduling serves as the foundation for delay analysis. The contractor establishes a baseline schedule approved by the owner at the beginning of a project, and submitting monthly progress updates. Where delays occur, the contractor often submits a time extension request, and must demonstrate both factual causation (the delay event occurred) and legal causation (the delay actually impacted the critical path).

Time-related costs are categorised differently based on delay causation. Excusable delays (weather, unforeseen conditions, owner changes) typically entitle contractors to time extensions but not necessarily compensation, while compensable delays (owner-caused delays, defective drawings) trigger both time and cost recovery including extended general conditions, escalation costs and inefficiency impacts. Acceleration costs arise when contractors are directed to maintain original schedules despite excusable delays, creating claims for premium time, additional labour and equipment costs.

Concurrent delay doctrine addresses situations where multiple delay causes occur simultaneously, with courts applying different approaches depending on jurisdiction. For concurrent delays, contractors typically may recover time extensions but not time-related compensation.

Owners and developers typically protect themselves from contractor-caused delay through a mix of monetary remedies and other rights spelled out in the contract, supported by state-law rules on damages and enforceability. The most common monetary remedy is contractual liquidated damages, which is a daily amount the contractor must pay if completion slips beyond the contractual date without excuse. The stipulated amount must not be a penalty and must be reasonable at the time that the contract was made. It is intended to compensate the owner for foreseeable damages such as loss of use, extended financing and overheads. Absent liquidated damages, the contractor may be liable for “general” delay damages, such as demonstrable extended project management, consulting and financing costs or lost rent or revenue. 

A contractor’s entitlement to an extension of time is controlled by the contract’s time-extension, notice and claim procedures. Those procedures are generally enforceable and, subject to state-law limitations, may allocate delay risk between the parties by defining which delays are excusable, which are compensable, which are time-only and what notice is required to preserve the claim.

Typically, the contractor requests an extension of time by giving timely written notice after the delaying event is known or reasonably should be known, followed by a more complete submission identifying the event, the affected work, the contract provision relied on, mitigation efforts and the number of days requested. The request may be styled as a change order request, time impact analysis (TIA), request for equitable adjustment or formal claim. Extensions are generally awarded for excusable delays: events beyond the contractor’s reasonable control and not caused by the contractor or its subcontractors. Common examples include owner-directed changes, late access, delayed owner decisions or approvals, defective or incomplete owner-furnished plans and specifications, differing site conditions, utility conflicts, unusually severe weather, force majeure events, governmental delays, and interference by separate contractors. Owner-caused delay may be both excusable and compensable; neutral delay usually supports time only; contractor-caused delay is generally non-excusable.

The extension is usually measured by impact to the “critical path” of the project. The critical path is the sequence of activities that controls the project’s completion date – typically the longest path through the critical path method (CPM) schedule, or the path with the least available “float” – that is, schedule buffer. A delay does not automatically justify more contract time merely because it occurred. The contractor usually must show that the event delayed critical work, consumed available float, or pushed a contractual milestone or completion date. Delays to non-critical activities may not support an extension unless they become critical or affect another activity that controls completion.

Force majeure clauses are often a standard but rarely considered part of construction contracts. The numerous impacts of the COVID-19 epidemic, however, brought renewed interest and litigation regarding these clauses. Often “form” language at the back of lengthy construction contracts took centre stage in assigning responsibility for unanticipated delays and cost increases. A typical form of a force majeure clause grants contractors non-compensable extensions of time.

The scope of a “force majeure” clause is established in the contract among the parties. Typical provisions cover events beyond the reasonable control of the affected party that prevent or materially delay performance, commonly including acts of God (hurricanes, floods, earthquakes, wildfires), severe or abnormal weather, war, terrorism and civil unrest, government actions (shutdown orders, permitting moratoria, import/export restrictions), labour disruptions (strikes, lockouts not limited to the contractor’s workforce) and, increasingly, pandemics and public health emergencies.

Unforeseen circumstances are addressed through contract terms and often state statutes, with parties contractually defining both the types of events and the associated remedies. A major category of such circumstances is differing site conditions (DSCs), which are unforeseen physical conditions encountered at the project site. Common scenarios involve the ground conditions encountered at the site, such as rocks, cobbles, boulders, unstable excavations and the amount, presence or absence of water. DSCs are typically divided into (i) conditions that differ materially from those indicated in the contract documents, and (ii) unknown conditions of an unusual nature that differ from those ordinarily encountered. DSCs generally entitle the contractor to both time and cost adjustments, reflecting the owner’s superior position in providing site information. Various state statutes may prevent owners from disclaiming responsibility for ground conditions and give contractors statutory rights and procedures for additional time and compensation.

Disruption is recognised as a distinct legal and contractual ground for both extension of time and additional compensation in both federal and state courts. Disruption claims compensate contractors for working less efficiently than planned due to another party’s actions, making the work more difficult and expensive than anticipated.

Disruption claims are often accompanied by delay claims, but disruption is a distinct damage and does not require proof of overall project delay to be compensable. Disruption claims typically require: (i) the other party’s liability for the disrupting event, (ii) causation linking that event to a loss of productivity or inefficiency, and (iii) resultant injury in the form of quantifiable increased costs. Disruption damages are often difficult to prove specifically and several methodologies are commonly used, including a measured mile analysis, the modified total cost method and reliance on industry and economic data for typical inefficiencies and impacts.

Certain categories of liability are generally treated as non-waivable as a matter of public policy. Most notably, parties cannot contractually exclude liability for fraud, intentional misconduct or knowing violations of law. In practice, while contractors, subcontractors and design professionals frequently negotiate limitations of liability, waivers of consequential damages and other risk-allocation mechanisms for commercial breaches, those provisions will not be effective to shield a party from deliberate wrongdoing or unlawful acts.

On public projects, additional mandatory rules commonly limit the extent to which risk can be shifted to contractors. For example, public owners are generally prohibited from requiring bidders to assume responsibility for the completeness or accuracy of design documents prepared by the owner or its consultants, except in procurement models where the contractor has accepted design responsibility (such as design-build). Similarly, many jurisdictions restrict the enforceability of “no damages for delay” clauses in public construction contracts, particularly where delays are caused by the owner and are unreasonable or not reasonably contemplated at the time of contracting.

US law generally recognises both “gross negligence” and “wilful misconduct”, although the terminology, elements and consequences vary by state. California’s civil jury instructions, for example, describe gross negligence as the lack of any care or an extreme departure from what a reasonably careful person would do in the same situation.

Wilful misconduct is generally a still higher standard. It ordinarily requires intentional conduct, knowledge of a serious risk or conscious disregard of consequences; not merely poor judgement, defective work or negligent project administration. Court decisions frame the concept similarly, describing wilful misconduct as involving either an intent to harm or an act done with a positive, active and absolute disregard of its consequences. In construction disputes, the distinction may matter where a party seeks to avoid a contractual limitation, pursue punitive damages, defeat an indemnity or release provision or characterise conduct as something more serious than breach of contract, professional negligence or deficient performance.

These concepts are governed primarily by state common law, statutes and public-policy rules, not by a single national construction code. As a general proposition, sophisticated parties may allocate ordinary commercial risk by contract, including through indemnity clauses, liability caps, exclusions of consequential damages, insurance requirements, waiver provisions and notice requirements. However, many jurisdictions impose limits on provisions that attempt to excuse or materially limit liability for fraud, intentional wrongdoing, wilful misconduct, statutory violations or gross negligence. 

Punitive damages are available in most US jurisdictions, but they are an extraordinary remedy and not a routine contract remedy. They require proof of conduct beyond mere breach of contract or ordinary negligence, such as fraud, malice, oppression, intentional misconduct, reckless indifference or conscious disregard of the rights or safety of others. In construction cases, punitive damages therefore tend to arise only in exceptional circumstances, such as intentional concealment of dangerous defects, fraudulent payment practices, deliberate safety violations or other aggravated wrongdoing. Even where punitive damages are allowed under state law, federal constitutional due process limits apply; the US Supreme Court has instructed courts to consider the reprehensibility of the defendant’s conduct, the relationship between punitive and compensatory damages, and comparable civil penalties. 

Construction contracts can have important terms that limit the parties’ claims and damages. Common limitations can include various provisions including waivers of consequential damages, caps on recoverable damages and liquidated damages for delay. The meaning and scope of what qualifies as a consequential damage can itself be uncertain, but a common example is a contractor’s claim for lost profits from other projects allegedly caused by delays or changes on the project under contract. Contracts may also cap the contractor’s aggregate liability, sometimes by reference to the contract sum, available insurance or a fixed dollar amount. Liquidated damages are widely used to fix the owner’s remedy for the contractor’s late completion, typically as a daily rate specified in the contract. Common law requires that the stated amount is a reasonable pre-estimate and not a penalty. Construction contracts increasingly include what is sometimes known as “reverse” liquidated damages, which establishes a fixed daily rate that the owner is liable to the contractor for as compensation for owner-caused delays. These reverse liquidated damages clauses can give the owner protection against inflated or increased contractor overhead costs arising during the work. A particularly contentious form of liability limitation is a “no damages for delay” clause, which would serve to grant only non-compensable time extensions rather than monetary damages for delay. The use of such clauses is often prohibited or restricted in public works contracts.

Indemnity provisions are a standard feature of US construction contracts and are widely used to allocate risk among project participants. However, their enforceability is subject to significant statutory and public policy constraints that vary by jurisdiction. As a general rule, many states prohibit indemnity provisions that require one party to indemnify another for the indemnitee’s sole negligence or wilful misconduct.

In practice, indemnities in construction contracts most commonly address third-party claims for bodily injury or property damage arising from project activities, along with associated defence costs. They may also extend to certain regulatory or code-related liabilities attributable to the indemnitor’s performance. For example, a subcontractor will often agree to indemnify the general contractor for claims caused by its defective work or unsafe jobsite practices. However, consistent with statutory limitations in many jurisdictions, such provisions generally do not extend to losses caused solely by the general contractor’s or owner’s negligence, design errors furnished to the subcontractor or other upstream fault outside the subcontractor’s control. These legal constraints are intended to prevent upstream parties from shifting their own misconduct onto downstream contractors or subcontractors through contract language alone.

Construction risk is most commonly managed through a combination of surety bonds, insurance, indemnitees and contractual guarantees. The principal instruments are performance bonds (guaranteeing completion of the work) and payment bonds (guaranteeing payment to subcontractors and suppliers). On public projects, these bonds are typically required by statute under the Miller Act at the federal level and “Little Miller Acts” at the state level (including California). Private projects may also require bonds, but only by agreement. In addition, owners frequently require letters of credit or parent company guarantees, particularly where the contractor is a special-purpose entity or presents heightened credit risk.

The most common construction insurance requirements are general liability, workers’ compensation, automobile liability and builder’s risk insurance, although other coverage may be required on specific projects.  Projects may use a “Contractor Controlled Insurance Program”, an “Owner Controlled Insurance Program”, or some combination of each.

Builder’s risk insurance also is commonly obtained and provides property insurance coverage for the work under construction, materials and equipment against fire, theft, vandalism and weather damage until project completion. Defective workmanship and design are typically not covered.

Professional liability insurance is typically carried by architects, engineers and design professionals, covering errors and omissions in design services, though coverage often excludes construction means and methods. Professional liability policies typically feature claims-made coverage with extended reporting periods.

Construction contracts commonly treat insolvency as a default because financial distress can threaten project completion, payments to contractors and subcontractors, insurance, bonding, warranties and closeout.  Typical clauses may allow the non-insolvent party – after required notice and any cure period – to suspend performance, withhold further payment, demand adequate assurances, require replacement of an insolvent subcontractor, supplement or take over the work, terminate for cause or call on payment or performance bonds. The provisions usually differ by party. If the owner becomes insolvent, the contractor’s concern is payment security and may include suspension, termination, lien rights, stop payment remedies or bond rights where available. If the contractor becomes insolvent, the owner’s concern is completion and protection against subcontractor and supplier claims, so the contract often focuses on takeover rights, assignment of subcontracts, use of retained funds, replacement contractors and performance bond remedies. If a subcontractor becomes insolvent, the prime contractor typically has similar replacement and backcharge rights at the subcontract level.

Most US construction contracts reflect “risk allocation” rather than express “risk sharing”, as the latter concept is sometimes used or applied internationally. Common types of risk allocations on construction projects include schedule and delay risk, cost escalation and procurement risk, design development and co-ordination risk, subcontractor co-ordination, ground conditions and access to the project site. Schedule risk is typically allocated through excusable delay provisions, which grant time extensions for defined events, combined with liquidated damages that establish the owner’s remedy for late completion. Cost and procurement risks can sometimes be allocated through escalation clauses, material allowances or owner-approved substitutions, particularly where supply chain volatility is anticipated. Design risk, especially in design-build scenarios, is allocated through a hybrid structure in which the contractor assumes responsibility for design completion, but the owner retains risk for performance criteria, bridging documents or owner-furnished information.

Key personnel designations are common for public projects and larger private projects. These provisions requires contractors to identify specific individuals who will oversee critical project functions, including project managers, superintendents and safety coordinators. They typically include detailed qualifications requirements (education, certifications, experience levels) and substitution restrictions requiring owner approval before replacing designated personnel.

Licensing requirements mandate that certain work be performed under supervision of appropriately licensed professionals – such as electrical work requiring licensed electricians or structural modifications requiring professional engineer oversight – with contractors bearing responsibility for ensuring all personnel maintain current, valid licences throughout the project duration.

It is of course typical and expected that general contractors will subcontract aspects of the work to specialty subcontractors. Indeed, a general contractor’s positive relationships with key subcontractors is something that informed owners will credit. Many specialty trades of work are specially licensed under state contracting laws and therefore portions of the work must be performed by subcontractors holding applicable licences. State licensing laws can impose penalties or forfeiture of payment if work is subcontracted to unlicensed entities. The prime contract may specify which scopes may or must be subcontracted, require the owner’s prior written approval of proposed subcontractors, and also include detailed “flow-down” clauses that bind subcontractors to the same technical, schedule, safety and dispute resolution requirements that apply to the prime contractor. Regardless of subcontracting, general contractors remain responsible to the owner for the acts and omissions of their subcontractors. Public works contracts add further constraints: bid documents often require disclosure of key subcontractors at tender, limit substitution of listed subcontractors without agency approval, and may restrict subcontracting of certain “core” work to ensure that the prime retains meaningful self performance.

Intellectual property provisions are primarily structured around ownership and licence rights. Design professionals or design-builders typically retain ownership of the instruments of service (drawings, specifications, models), while granting the owner a non-exclusive, project-specific licence to use them for construction, operation, maintenance and in some cases future modifications, usually conditioned on payment and limited to the project unless otherwise negotiated. Contractors receive a narrower licence to use the documents solely for construction purposes, with restrictions on reuse and reliance.

In the United States, remedies for breach of a construction contract are primarily contractual, supplemented by generally applicable common law and statutory principles. The usual starting point is compensatory damages: the injured party seeks to be placed, as nearly as money can do it, in the position it would have occupied had the contract been properly performed. In construction cases, the distinction between “direct” and “consequential” damages is often central. Direct damages are the natural and immediate result of the breach, such as the cost to complete unfinished work, the cost to repair defective work, unpaid contract balances, approved change orders, or wrongfully withheld retention. Consequential damages are more remote losses that flow from the breach because of the injured party’s particular circumstances, such as lost revenue from delayed opening, loss of use, financing losses, business interruption or reputational harm.

For the owner, common remedies include withholding payment where permitted, requiring correction of defective or non-conforming work, rejecting non-conforming work, assessing liquidated damages for late completion, supplementing the contractor’s forces, terminating for cause or for convenience, completing the work through others and recovering the reasonable excess cost of completion. Owners may also pursue warranty claims, indemnity, insurance proceeds and performance bond remedies where available. In a typical contractor default scenario, the owner’s direct damages may include completion costs, repair costs, professional fees needed to address defective work, extended project administration costs, delay damages and other losses caused by the contractor’s breach, subject to the contract’s limitations, notice requirements and damages waivers.

For the contractor and subcontractors, the principal remedies are usually payment- and time-based. Contractors may seek unpaid progress payments, retention, final payment, compensation for extra work, disputed change orders, delay and disruption damages, extended general conditions, loss of productivity, remission of liquidated damages, interest, attorney’s fees where authorised and extensions of time. If the owner wrongfully suspends or terminates the work, fails to provide access, delays approvals, issues defective design information or otherwise interferes with performance, the contractor may also pursue damages for increased costs of performance and, where permitted, lost profit on work not performed. Subcontractors and suppliers may also have statutory security remedies, such as lien, stop-payment or payment bond rights, depending on the project type and governing law.

Designers and construction management firms are typically governed by their own professional services or management agreements rather than the prime construction contract, unless they are part of an integrated delivery structure such as design-build, EPC or CMAR. Their remedies commonly include unpaid fees, additional-services compensation, reimbursable expenses and wrongful termination damages. Their exposure is usually tied to the scope of services they accepted, including professional negligence, breach of contract, errors or omissions, deficient administration or contractual indemnity obligations.

Limitations on remedies are common in construction contracts, design agreements and other construction-related agreements. Courts usually enforce limitations on remedies if they are clearly drafted and not contrary to statute or public policy. Examples of limitations that may not be enforceable are ones that are unconscionable (that is, they shock the conscience) or seek to relieve a party of their active negligence or willful acts of malfeasance. 

There are many types of limitations used in construction related contracts. They include waivers of consequential damages (eg, lost profits or loss of use), liquidated damages, caps on liability (often tied to the contract price, a multiple of fees or available insurance), exclusive remedy clauses and limitations on the time within which claims must be brought. These provisions are widely used across owner–contractor, contractor–subcontractor, and owner–designer agreements to create predictability and allocate risk.

Most standard form agreements (eg, industry templates) include a mutual waiver of consequential damages and allow negotiated caps on direct damages. Liquidated damages clauses often are used in standard agreements to limit exposure to damages for delay.

Construction contracts may have terms providing that certain damages or procedures are the “sole and exclusive remedy” for breaches, but statutes and case law provide important additions and limitations. An owner’s claim for contractor-caused delay and late completion is often limited by stipulation as liquidated damages, but case law provides that such amounts cannot be an unlawful penalty. The contractor’s claim for delay is typically not stipulated as liquidated damages payable to the owner, and the law may prevent the owner from applying limitations on the contractor’s recoverable damages in some situations such as differing site conditions and owner changes. 

Courts in most states require explicit and unambiguous language to limit a party to a single contractual remedy, and courts are reluctant to interpret such clauses expansively where doing so would insulate a party from its own wilful misconduct, fraud or violation of non-waivable statutory protections. In practice, parties strengthen enforceability by using targeted sole remedy language, for example stating that liquidated damages are the owner’s sole remedy for delay, by expressly carving out fraud, willful misconduct and statutory rights such as mechanics’ liens and prompt payment protections, and by aligning exclusive remedies with insurance, bonding and dispute resolution procedures rather than attempting to displace the larger remedial framework imposed by state law or, on federal projects, the FAR.

A common example of excluded damages is through a mutual waiver of consequential damages, which removes exposure for losses that are indirect or not the immediate cost of performing the work. These typically include lost profits, loss of use or revenue, loss of business opportunity, loss of financing or bonding capacity and reputational harm. Owners can waive claims for lost income or use of the completed facility, while contractors can waive claims for lost profits on other work, home office overhead or financing impacts. These waivers are common in private projects and are also sometimes incorporated into public contracts, though their enforceability may be more closely scrutinised depending on the jurisdiction and statutory framework.

Retention and suspension rights generally cannot be contractually excluded. Retention and suspension provisions are common features in construction contracts and are typically negotiated to allocate risk and manage payment timing. However, rather than being freely excludable, these rights are often regulated and, in some cases, limited by statute, particularly on public projects and in jurisdictions with prompt payment laws. In practice, retention (ie, the withholding of a portion of progress payments as security for performance) is typically capped on public works (usually at 5%) and must be released within specified timeframes after project completion and acceptance. On private projects, parties generally have greater flexibility to negotiate retention terms, but statutory prompt payment provisions may still impose timing requirements and restrict unreasonable or bad faith withholding. Contract provisions that conflict with these statutory protections may be unenforceable.

Similarly, the right to suspend performance for non-payment is often addressed by both contract and statute. While contracts commonly include detailed procedures governing suspension (eg, notice requirements and cure periods), provisions that attempt to eliminate the right to suspend altogether may be limited or invalid where they conflict with prompt payment laws or public policy. Owners, for their part, usually retain contractual rights to withhold payment or suspend work for defined reasons (eg, defective work or safety concerns), subject to duties of good faith and reasonableness. 

On federal projects, payment and performance rights are further shaped by statutes and regulations that cannot be overridden by contract. The Prompt Payment Act establishes deadlines for payment and interest penalties for late payment on federal contracts, while the Federal Acquisition Regulation (FAR) governs the use of retention and provides for equitable adjustments in the event of government-caused suspensions. In addition, the Miller Act restricts pre-performance waivers of payment bond rights, ensuring that contractors and subcontractors retain a statutory remedy for nonpayment. Taken together, these frameworks mean that retention and suspension rights are generally defined by contract, but bounded by mandatory legal protections, rather than entirely subject to contractual exclusion.

Termination for cause provisions allow either party to terminate when the other materially breaches contract obligations, with typical grounds including contractor default (failure to prosecute work diligently, insolvency, abandonment, repeated safety violations) or owner default (non-payment, failure to provide site access, interference with contractor operations). Most contracts require notice and cure periods (typically seven to 30 days) allowing the breaching party opportunity to remedy defaults before termination becomes effective. Immediate termination rights may exist for egregious breaches such as bankruptcy filing, criminal conduct or safety violations posing imminent danger.

Termination for convenience clauses permit owners to terminate without cause, typically requiring advance notice (30–60 days) and providing contractors with compensation for work performed plus reasonable overhead and profit on unperformed work.

Compensation upon termination varies significantly based on termination grounds and contract language. Termination for contractor default typically limits recovery to contract value of acceptable work performed, minus costs to complete and cure defects, often resulting in no payment or contractor liability for completion costs exceeding the contract balance. Termination for owner convenience generally entitles contractors to payment for completed work, materials procured, demobilisation costs and profit on completed work. 

Construction disputes are generally adjudicated either in the state and federal court systems or before private arbitrators, with the particular forum determined by contract and whether the project is public or private. For state law disputes on private projects, parties most often litigate in the general civil trial courts of the relevant state, which have broad jurisdiction over contract, tort and mechanics’ lien claims and can grant both monetary and equitable relief such as lien foreclosure or specific performance. Federal District Courts become available primarily when there is a federal question (for example, on federal public works governed by federal procurement statutes) or diversity of citizenship and the amount in controversy threshold is met.

In addition to courts, many construction contracts may designate binding arbitration as the regular dispute forum. US law (including state law and the Federal Arbitration Act) generally favours enforcement of such arbitration agreements. Public works disputes may be subject to specialised administrative or statutory regimes before they reach a court or arbitrator: for example, claim and certification procedures under the Federal Acquisition Regulation on federal projects, or contractually mandated claims processes and administrative hearings for state or local public entities in California.

Alternative dispute resolution is widely used in construction projects and is often built into standard contracts as a prerequisite to, or substitute for, litigation. The most common forms are mediation (a non-binding, facilitated negotiation) and arbitration (a binding, private adjudication). Many agreements require mediation as a first step, followed by arbitration. There are many national, regional and local organisations that provide alternative dispute resolution services, and have neutral mediators and arbitrators affiliated with them, such as the American Arbitration Association and JAMS.

Other types of dispute resolution procedures are used for larger and more complex projects, particularly public agencies. Those include the use of dispute review boards (DRBs) and evaluative mediation involving legal review of the parties’ positions rather than facilitated negotiation.
