Project Closeout & Evaluation
Project Closeout & Evaluation
Closeout has two milestones that must never be confused. Substantial completion is the stage at which the work is sufficiently complete for the owner's intended use. It triggers the warranty period, transfers risk of loss/insurance to the owner, permits occupancy, stops liquidated damages, and typically releases part of retainage. Final completion follows correction of all punch list items, delivery of closeout documents, and final payment.
Deliverables to know: punch list (incomplete or defective work), certificate of substantial completion (the architect's determination fixing the warranty start date), record/as-built documents, O&M manuals, warranties and guarantees, spare parts and attic stock, final lien waivers and the contractor's affidavit, final change order reconciliation, and consent of surety for final payment. The certificate of occupancy is issued by the authority having jurisdiction, not by the architect.
Post-occupancy evaluation closes the loop: assess functional performance, energy use, durability, and user satisfaction; feed lessons learned into future projects. Commissioning verifies that systems perform as designed and often returns near month ten for seasonal testing.
Traps: minor punch list items do not delay substantial completion where the owner can occupy and use the work; retainage is not automatically released in full at substantial completion; warranties begin at substantial completion, not final payment.
Rule of thumb: $4.0M contract at 5% retainage = $200,000 held. At substantial completion the owner may release a portion (some specifications allow reducing retainage to 200% of the punch list value); the balance is paid with final payment, conditioned on lien waivers. Do not release funds before waivers arrive.
