Substantial completion marks the stage in a construction project where the work is complete enough for the owner to use the facility, even if minor tasks remain. At this point, the owner assumes responsibility for the property, and the contractor’s liability begins to shift.
Why Substantial Completion Matters
It signifies the transition from construction to occupancy, triggering key contract provisions such as warranty periods, retainage release, and final payments.
Determining Substantial Completion
- The contractor must complete all critical project elements required for safe and functional use
- A final inspection is conducted, and a certificate of substantial completion may be issued
- Any remaining work is documented on a punch list for final resolution
