It depends on the signed contract, the governing law, and why the work on the critical completion path was delayed. A contractor may absorb costs or owe liquidated damages when its own failure causes late completion. An owner may owe a time and cost adjustment for an owner-caused delay, a compensable change, or acceleration ordered for the owner’s benefit. An excusable event may justify more time without automatically requiring the owner to pay the contractor’s added overhead. When delays overlap, both delay damages and liquidated damages can be limited.
The examples below draw on United States federal procurement clauses and Philippine Construction Industry Arbitration Commission (CIAP) guidance. Those systems illustrate different contract rules; they do not decide a private project in another jurisdiction. For a live dispute, have the actual contract, amendments, schedules, notices and governing law reviewed by a qualified construction lawyer or claims professional.

Start with the contract, not the invoice
Delay responsibility is usually an exercise in contract interpretation and schedule proof. Before assigning a payer, identify these provisions in the executed agreement and every change order:
Recommended Free Tools
- the required substantial-completion or final-completion date;
- the definition of a day of delay and any milestone dates;
- the time-extension clause, including qualifying events and notice deadlines;
- the liquidated-damages clause and the stated daily amount, if any;
- change-order language covering price and time adjustments;
- owner-furnished information, access, approvals and materials obligations;
- acceleration, suspension and recovery-schedule provisions;
- the procedure for submitting delay, disruption and extra-cost claims; and
- the governing law, dispute forum and required records.
A subcontract may allocate risk differently from the prime contract. Flow-down clauses, “no-damage-for-delay” language, notice conditions and waiver provisions can materially change the result. A schedule narrative alone cannot override an unambiguous contractual allocation.

Who usually pays in each delay situation?
| Delay situation | Key question | Likely financial result under the cited examples |
|---|---|---|
| Contractor-caused late completion | Did contractor performance push the contractual completion date, and is a valid liquidated-damages clause in place? | The contractor may owe the contract’s stated daily liquidated-damages amount and generally bears its own extended costs. |
| Excusable event beyond contractor control | Does the contract recognize the event, and were notice and proof requirements met? | More time may be available. Added money is not automatic. |
| Owner delay, defective information or owner change | Did an owner act or omission affect critical completion, and does the contract allow a price and time adjustment? | The contractor may receive a time extension and recover proven additional costs, subject to the contract. |
| Owner-requested acceleration | Who requested or caused the faster completion, and was the direction documented? | Acceleration for the owner’s convenience or fault may be compensable extra work under an applicable clause. |
| Acceleration to recover contractor slippage | Was the contractor trying to cure its own delay? | The contractor commonly bears the recovery effort, unless the contract or a later agreement says otherwise. |
| Concurrent delay | Can the critical-path effects of separate causes be separated and allocated? | Cost recovery may be denied or reduced, and owner liquidated damages may be unenforceable in some circumstances. |
These are starting points, not automatic outcomes. The same event can produce different results under different wording and jurisdictions.
Contractor-caused delay: when the contractor pays
A contractor-caused delay occurs when a contractor’s breach, late procurement, deficient work, inadequate staffing or other controllable act or omission delays a contractual completion date or critical milestone. The contract may give the owner a right to liquidated damages rather than requiring proof of every individual loss.
How liquidated damages work
Federal Acquisition Regulation (FAR) clause 52.211-12 provides a clear example: if the contractor fails to complete within the contract time, it pays the amount inserted in the contract for each calendar day of delay until completion or acceptance. The clause page identifies Federal Acquisition Circular 2026-01, effective March 13, 2026. The amount is contract-specific; the clause itself does not establish one universal rate.

1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsFAR subpart 11.5 states that liquidated damages are appropriate when timely performance is important and the resulting damages would be difficult or impossible to estimate accurately or prove. For federal construction, the daily rate is intended to account for estimated government inspection and superintendence and other expected expenses. A private contract must still satisfy its own governing law: a court may scrutinize whether the amount was a reasonable estimate of anticipated loss rather than an unlawful penalty.
What the contractor still has to prove
Even where a liquidated-damages clause exists, the owner generally must establish the contractual completion date, the actual completion or acceptance date, and the number of chargeable days. Owner-caused, excusable or concurrent delay can reduce the chargeable period. A contractor should challenge a calculation that counts days during which the owner prevented performance or granted an extension.

Excusable delay: more time does not always mean more money
Excusable delay is commonly a delay caused by an event outside the contractor’s control and without its fault or negligence, subject to the contract’s definitions and exceptions. Examples may include certain extraordinary weather events, government actions, labor disruptions or other listed causes, but the contract controls which events qualify.
FAR clause 52.249-14 illustrates the distinction. When the specified determination is made, the schedule may be revised for a qualifying excusable failure. The clause does not promise reimbursement of extended field overhead, home-office overhead, financing cost or other delay expenses. Some contracts provide both time and money for particular owner-risk events; others provide time only. Read the remedy sentence, not just the definition of excusable delay.
Notice and proof are usually conditions
Most clauses require prompt written notice, a description of the event, the anticipated effect and supporting schedule evidence. Missing a deadline can bar an otherwise valid claim. A notice should identify the contract provision relied on, preserve the right to seek both time and money where allowed, and be updated as the effect becomes measurable.
Owner-caused delay and changes: when the owner may pay
Owner-caused delay can arise from late site access, late approvals, defective or incomplete design information, owner-directed resequencing, suspension, interference by another owner contractor or a change in the work. The contractor must still show causation: an owner action must affect activities that control completion or otherwise create compensable inefficiency under the contract.
Time adjustment for a change
FAR clause 52.211-13 states that an extension for contract changes depends on how much the changes delay completion of project elements. That approach requires a schedule analysis rather than a blanket extension for every change. A change that consumes available float may not move the completion date; a change that affects the critical path may.

Cost adjustment
Where the contract permits compensation, the contractor may claim demonstrable costs such as additional supervision, equipment, labor, temporary facilities, extended insurance or financing, and subcontractor costs. Recovery normally requires segregation of delay costs from ordinary project costs and mitigation of avoidable expense. A time extension alone is not proof of a compensable amount.
Philippine CIAP guidance provides a jurisdiction-specific example in which listed owner-delay circumstances support a time extension. It should not be generalized to every Philippine contract, much less to projects governed elsewhere.
Acceleration: who pays for finishing sooner?
Acceleration is additional effort intended to achieve an earlier date or recover lost time. The reason for acceleration is decisive.
Directed or owner-benefit acceleration
Under the cited Philippine guidance, acceleration ordered for the owner’s convenience, or required because of owner fault or delay, is treated as extra work paid through a change order. The contractor should obtain a written directive stating the target date, required measures, price method and schedule assumptions before adding shifts, crews or equipment.
Recovery of contractor-caused slippage
The same guidance treats acceleration needed to catch up from contractor fault as the contractor’s burden. That can include overtime, additional crews, expediting and premium freight. A contractor should not assume that an owner’s request to “recover the schedule” is compensable without documenting the underlying cause and obtaining a priced change order.

Constructive acceleration risk
A dispute can arise when an owner denies a justified extension but insists on the original date, effectively forcing acceleration. Whether that creates a compensable claim depends on the contract, notice, proof of entitlement to the extension and the governing law. Preserve the extension request, the denial, schedule updates and actual acceleration costs.
Concurrent delay: when causes overlap
Concurrent delay exists when separate causes—often one owner-responsible and one contractor-responsible—affect the same critical completion period. The analysis is fact-specific: the timing, critical-path activities, float, each cause’s effect and the parties’ ability to separate impacts all matter.
Federal Transit Administration guidance states that, in specified concurrent-delay situations, a contractor may not recover increased delay costs and owner liquidated damages may not be enforceable when the owner’s contribution cannot be separated from other causes. That is not a universal rule. Other contracts and courts use different tests, including first-in-time, dominant-cause or apportionment approaches.
Practical schedule questions
- Which activities were critical on the accepted baseline and each update?
- Did the owner event and contractor event occur during the same period?
- Did either event consume float without delaying completion?
- Can days or costs be separated by period, activity or resource?
- Did either party worsen the effect by failing to mitigate?
Time entitlement and money entitlement are separate decisions
Analyze every claim in two columns: time and money. An event may justify a non-compensable extension, prevent liquidated damages for the extended period, or support both an extension and proven costs. Conversely, a compensable change may increase price without moving the completion date if the contractor uses available float.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For each event, state the requested start and finish dates, affected activities, critical-path effect, contractual clause, notice date, mitigation steps and cost categories. Do not convert a claimed number of days directly into a cost claim without showing how labor, equipment, supervision and other expenses were calculated.

A step-by-step method for deciding responsibility
- Freeze the governing documents. Collect the signed contract, addenda, drawings, specifications, accepted baseline schedule, updates, change orders and amendments.
- Build a delay chronology. Record the event date, who acted, when the effect became known, notices sent and the date each activity actually finished.
- Classify the cause. Mark each event as contractor risk, owner risk, excusable risk, neutral risk or disputed.
- Test criticality. Compare the accepted baseline and contemporaneous updates to determine whether the event affected contractual completion or only float.
- Check notice and waiver. Match every notice to the contract deadline, delivery method and required content.
- Separate time from cost. Calculate the requested extension independently from extended or acceleration costs.
- Account for concurrency and mitigation. Identify overlapping causes and reasonable steps taken to reduce delay or expense.
- Apply the remedy clause. Determine whether the contract grants an extension, price adjustment, liquidated damages, a change order or no recovery.
- Submit a supported claim. Include schedules, daily reports, correspondence, labor and equipment records, invoices and a transparent calculation.
Records that protect a delay or extra-cost claim
- daily reports identifying work locations, crews, equipment, weather and idle time;
- approved baseline and update schedules in native format, with logic and calendars;
- meeting minutes, requests for information, submittal logs and approval dates;
- site-access records, inspection requests and photographs dated to the event;
- written directives, change proposals, reservations of rights and extension notices;
- payroll, time sheets, equipment logs, purchase orders, freight bills and subcontractor notices;
- records of mitigation, resequencing, overtime and rejected alternatives; and
- acceptance, substantial-completion and punch-list documentation.
Contemporaneous records are more persuasive than a reconstruction prepared after the project closes. Keep the schedule files that were actually used, not only a final summary printout.
Common mistakes that shift or weaken responsibility
- Counting every calendar day. Only days allocated to the contractor under the contract should support liquidated damages.
- Assuming an extension pays overhead. Confirm that the clause grants compensation, not merely additional time.
- Using a global cost claim. Tie each cost to a documented event and period.
- Accelerating without a written direction. Clarify whether the effort cures contractor delay or responds to owner risk.
- Ignoring subcontract notices. Prime-contract deadlines often flow down, and late notice can impair pass-through recovery.
- Relying on a schedule without an accepted baseline. A reliable contemporaneous schedule is essential to critical-path proof.
- Overlooking concurrency. An owner event does not automatically excuse all contractor delay during the same dates.
- Applying a foreign rule mechanically. FAR and Philippine examples are not a substitute for the law governing the project.
Narrow statutory example: certain Architect of the Capitol contracts
United States Code 2 U.S.C. § 1816 requires liquidated-damages provisions for certain Architect of the Capitol construction contracts above the statutory threshold and allows rate adjustment after the specified written determination. This is a narrow federal statutory example, not a general rule for private construction or every U.S. government contract. The contract and the statute’s exact scope must be checked before relying on it.
When to obtain professional help
Get advice promptly when a notice deadline is approaching, the owner threatens liquidated damages, a major change has disrupted sequencing, acceleration costs are accumulating, or concurrent delay prevents a clean allocation. Provide counsel or a claims professional with the contract, governing-law clause, schedule files, notices, correspondence and cost records. They can test entitlement and quantum without assuming that a favorable schedule narrative guarantees recovery.
The payer is ultimately determined by the risk allocation in the contract, the proven cause and effect on completion, compliance with notice procedures, and the governing jurisdiction. Treat time, money, liquidated damages and acceleration as separate remedies, then document each one against the project record.
