Excusable Delay

A project delay caused by events outside the contractor's control, entitling the contractor to a time extension.

Excusable delays are project delays caused by events for which the contractor is not responsible: severe weather beyond reasonable expectation, owner-caused delays, design errors, unforeseen site conditions, force majeure events, and certain third-party actions. Standard construction contracts (AIA, ConsensusDocs, EJCDC) entitle the contractor to a time extension equal to the actual delay impact, but not always to additional money.

Excusable delays divide into compensable (contractor gets time and money: typically owner-caused delays) and non-compensable (contractor gets time but no money: typically weather, force majeure). Documenting each delay event in real time, citing the contract clause that excuses it, and tracking the schedule impact through the next monthly update are essential. Late or undocumented delay claims are a leading reason contractors lose otherwise valid time extensions.

Frequently asked questions

What qualifies as an excusable delay?+

Events outside the contractor's reasonable control: extreme weather beyond historical norms for the area, owner-directed changes, design errors, undisclosed site conditions, force majeure events (strikes, riots, acts of God), and third-party delays not caused by the contractor.

What is the difference between compensable and non-compensable excusable delay?+

Compensable means the contractor gets both a time extension and money for the delay impact (typically owner-caused). Non-compensable means time extension only, no money (typically weather, force majeure, and other no-fault events).

How do contractors preserve excusable delay claims?+

Document the event when it happens (notice in writing within the contract's time limit, often 7 to 14 days). Show the schedule impact in the next monthly update. Cite the specific contract clause that excuses the delay. Skipping the notice deadline is the single most common reason claims fail.
