Notice

In Plain English

A formal written communication required by the contract to protect your rights or trigger a process.

Definition

Notice in construction contracts refers to the formal written communications required by contract to preserve rights, trigger obligations, or initiate processes. Common required notices include notice of delay, notice of claim, and notice to cure a default. Failure to provide timely notice as required by the contract can result in waiver of rights and loss of remedies.

Why It Matters in Bidding

Notice provisions are the gatekeepers to nearly every contractual remedy, so a contractor that performs perfectly but misses a notice deadline can still forfeit time extensions and additional compensation. During bidding and at kickoff, estimators and project teams should map every notice requirement in the front-end documents so the obligations are tracked rather than discovered during a dispute.

Example

When a differing site condition surfaces during excavation, the project manager sends written notice to the owner within the contract's required window, preserving the right to a change order for the added rock removal that the estimator never carried in the base bid.

Frequently Asked Questions

Most contracts treat timely written notice as a condition precedent, meaning a missed deadline can waive the right to a time extension or extra compensation regardless of the claim's merit. Some courts soften this where the owner had actual knowledge and suffered no prejudice, but relying on that exception is risky.
Contracts usually specify the method, recipient, and timing, often requiring written notice delivered to a named party by mail, hand delivery, or sometimes email. Verbal notice and casual jobsite conversations rarely qualify. Following the exact delivery method and addressing in the contract is essential to preserve the right.
The high-stakes ones are notice of delay, notice of differing or changed conditions, notice of claim for additional compensation, and notice to cure a default. Each typically carries a short clock measured from when the event was or should have been discovered, so a notice log started at kickoff prevents lost rights.
