The Construction Industry: Built on Notice

Construction is one of the most dispute-prone industries in the world. Payment disputes, defective work claims, delays, change order disagreements, and contract interpretation fights are routine. What makes construction disputes unique is the elaborate system of statutory notices that govern them — mechanics liens, payment bond claims, notices of commencement and completion, and claims procedures that must be followed with precision. Missing a single notice deadline can extinguish hundreds of thousands of dollars in valid claims.

This guide covers the most critical construction notices, the strict timelines that govern them, and how to protect your right to payment on every project.

Mechanics Liens: The Ultimate Payment Protection

A mechanics lien (also called a construction lien, materialman's lien, or builder's lien) is a security interest in the improved property that secures payment for labor, materials, or services provided. If unpaid, the lienholder can foreclose on the property — a nuclear option that virtually guarantees payment. But the path to a valid lien is paved with strict notice requirements and even stricter deadlines.

The typical mechanics lien process involves:

  1. Preliminary Notice: Most US states require contractors, subcontractors, and suppliers to serve a preliminary notice (also called a notice to owner, pre-lien notice, or 20-day preliminary notice) within a specific timeframe — typically 20-60 days from first furnishing labor or materials. This notice informs the property owner and general contractor of your involvement in the project and your right to file a lien. Failure to serve preliminary notice on time forfeits your lien rights in many states.
  2. Notice of Intent to Lien: Some states require or strongly recommend a notice of intent to lien — a warning sent 10-30 days before actually filing the lien. This often prompts immediate payment without the cost and escalation of an actual lien filing.
  3. Mechanics Lien Filing: The lien must be filed (recorded) with the county recorder or similar office within a strict deadline — typically 60-120 days from last furnishing labor or materials, varying by state and your role (general contractor vs. subcontractor vs. supplier).
  4. Lien Foreclosure Action: After filing, you typically have 6-12 months to file a lawsuit to foreclose on the lien. Failure to foreclose within the deadline extinguishes the lien.

Payment Bond Claims (Public Projects)

Mechanics liens cannot be filed against public property (government buildings, schools, highways). Instead, general contractors on public projects are required to post a payment bond under the federal Miller Act (for federal projects over $100,000) or state "Little Miller Acts." Subcontractors and suppliers who are unpaid can make a claim against the bond.

Notice requirements are strict: under the Miller Act, a subcontractor with no direct contract with the general contractor must provide written notice to the general contractor within 90 days of last furnishing labor or materials. The lawsuit on the bond must be filed within 1 year. Missing these deadlines is fatal.

Construction Defect Notices

Most states have enacted "right to cure" or "notice of claim" statutes for construction defects. Before suing for defective construction, the claimant must typically serve a formal notice describing the alleged defects in detail and give the contractor a specified period (often 60-90 days) to inspect and offer to repair them. This is designed to reduce litigation by giving contractors the first opportunity to fix problems.

The notice must be specific — general complaints like "the work is shoddy" are insufficient. It should identify each defect by location, describe the nature of the defect, reference the applicable building code or contract standard, and include photographs or expert reports where available.

Delay and Disruption Claims

Most construction contracts require written notice of delay claims within a specific period — typically 7-21 days from when the delaying event first occurred. Even if the delay is the owner's fault (design changes, site access issues, late approvals), failure to give timely written notice may waive the claim. The notice should describe the delaying event, estimate the impact on the schedule and costs, and request a time extension and/or additional compensation.

International Construction Disputes

International construction projects are typically governed by FIDIC (International Federation of Consulting Engineers) contracts, which have their own elaborate notice and claims procedures. Under FIDIC Red Book, a contractor must give notice of a claim within 28 days of becoming aware of the event. The detailed claim must then be submitted within 42 days. These deadlines are strictly enforced by international arbitration tribunals.
