What is a delay claim in construction?

A delay claim is a contractor's formal request for a time extension, added compensation, or both, because the project was delayed by an event the contractor was not responsible for.

A delay claim is a demand by a contractor (or sometimes an owner) for relief when the project finished later than planned. The contractor asks for extra days, extra money, or both, and has to show three things: what caused the delay, that it pushed the critical path, and what it cost. Owners can bring the mirror image, usually by assessing liquidated damages.

Types of delay

How delays are usually classified
TypeExampleTypical relief
Excusable and compensableOwner late with permits, design changes, differing site conditionsTime and money
Excusable, non-compensableUnusually severe weather, many force majeure eventsTime only
Non-excusableContractor's own crew shortage or late material orderNone; contractor may owe damages
ConcurrentOwner and contractor delays overlapOften time only, depends on contract and jurisdiction

The contract decides which bucket an event falls into. An excusable delay clause, a force majeure clause, and a no damages for delay clause can change the answer completely.

How a delay claim works on a real job

Say a site contractor is building a $2.1 million parking structure. The owner's geotechnical report missed a buried tank. Excavation stops for 19 working days while the owner hires an environmental firm and gets approval to remove it. Foundations are on the critical path, so substantial completion slips.

The contractor sends written notice within the contract's deadline, documents the stop in its daily logs, and updates the schedule to show the impact. The claim then prices the extended time: idle equipment, a superintendent and trailer for 19 more days (extended general conditions), and any productivity loss from restarting. A tidy package ties each dollar to the delayed days.

The owner's scheduler will test it. Expect questions about whether the contractor could have resequenced work around the tank, whether any of the 19 days overlapped with the contractor's own slow rebar delivery, and whether the daily rates for equipment match the contract's rate schedule.

Common mistakes and disputes

  1. Missing the notice deadline. Many contracts bar a claim if written notice of claim is late, no matter how strong the facts.
  2. No schedule analysis. Saying the job was late is not enough; you need updates that show which delay drove the path.
  3. Mixing your own delays in. If your crew was short the same week, expect a concurrency fight.
  4. Pricing with a total cost method (bid versus actual) instead of tying costs to the delay. Courts and owners are skeptical of it.
  5. Signing a change order that waives further time or cost for the same event.

Delay claims overlap with differing site conditions, suspension of work, weather delays, and the broader claim process. If a delay comes from an unpaid change, your prompt payment rights by state may matter too.

Frequently asked questions

How long do I have to file a delay claim?

Whatever the contract says, which is often a short window after you knew or should have known of the delay. Read the notice clause before work starts and calendar it.

What is concurrent delay?

Two or more delays that overlap in time, one caused by the owner and one by the contractor, both affecting completion. Treatment varies by contract and jurisdiction, but it often results in a time extension without extra money.

Can a subcontractor bring a delay claim?

Yes, usually against the general contractor under the subcontract. If the owner caused the delay, the GC may pass the claim through to the owner.

What costs can be included in a delay claim?

Commonly extended general conditions, idle labor and equipment, escalated material costs, extended home office overhead in some cases, and lost productivity, all tied to the delay period.
