What Is Notice to Proceed in Construction?
Definition
A notice to proceed (NTP) is a formal written authorization from the project owner to the contractor directing them to begin work on a construction project. The NTP establishes the official start date of the contract and triggers the beginning of the contractual construction schedule.
The notice to proceed is one of the most important documents in the construction contract process. It marks the transition from pre-construction to active construction and formally authorizes the contractor to mobilize resources, order materials, and begin physical work on the site. Without an NTP, a contractor who begins work does so at their own risk.
The NTP typically references the contract agreement, states the date on which work may begin, and identifies the contractual completion date or the number of calendar or working days allowed for completion. In many contracts, the completion date is calculated by adding the contract duration to the NTP date, making the NTP the anchor point for the entire project schedule.
Sometimes an owner may issue a limited notice to proceed, which authorizes only certain pre-construction activities like procurement of long-lead items or site preparation, while the full NTP is pending. This approach helps maintain schedule momentum when final contract negotiations or financing are still being completed.
Why It Matters
The NTP establishes the contractual start date and, by extension, the completion deadline and any associated liquidated damages. Starting work without a formal NTP can create legal and insurance complications. Conversely, delays in issuing the NTP push back the entire project timeline and can entitle the contractor to time extensions or additional compensation.
How HomeFloorPlan Helps
HomeFloorPlan supports the transition from pre-construction to active construction by giving teams a shared platform where the latest plans and documents are accessible from day one. When the NTP is issued and work begins, field teams can immediately access current drawings, post updates, and begin tracking issues in context on the plans.
Frequently Asked Questions
What happens if work starts before a notice to proceed is issued?
Starting work without a formal NTP can create contractual, legal, and insurance complications. The contractor may not be covered under the project insurance policy, and any work performed may not be recognized under the contract terms. It is best practice to wait for a written NTP before mobilizing.
Can a notice to proceed be issued for only part of the work?
Yes, owners sometimes issue a limited or partial notice to proceed that authorizes specific activities like ordering long-lead materials or performing site preparation while the full NTP is pending. The limited NTP typically defines a maximum expenditure amount.
