Construction Project Closeout: A Phased Guide
A structured approach to construction project closeout that ensures nothing is overlooked and all obligations are met.
What Is Project Closeout?
Closing out a construction project is a pivotal phase that ensures all contractual obligations are met, documentation is complete, and the project is officially handed over. A structured approach to closeout can prevent delays, reduce costs, and enhance client satisfaction.
Project closeout is the final phase of the construction process, involving the completion of all project deliverables, fulfillment of contractual terms, and formal acceptance by the client. It encompasses activities such as final inspections, documentation submission, and financial settlements.

Phased Closeout Approach
Implementing a phased approach to project closeout can streamline the process and ensure nothing is overlooked. Below is a breakdown of the closeout phases aligned with project completion percentages:
Phase 1: 25% Completion – Initiate Closeout Planning
- Develop a preliminary closeout plan outlining required documentation and responsibilities.
- Establish a document control system for tracking closeout materials.
- Communicate closeout procedures to all stakeholders.
Phase 2: 50% Completion – Mid-Project Documentation
- Begin compiling operation and maintenance (O&M) manuals.
- Collect and organize warranties and guarantees from subcontractors.
- Ensure as-built drawings are being updated regularly.
Phase 3: 75% Completion – Pre-Substantial Completion
- Conduct preliminary inspections to identify potential punch list items.
- Verify that all systems are tested and operational.
- Schedule training sessions for the owner's maintenance personnel.
Phase 4: 90% Completion – Substantial Completion
- Complete all punch list items identified during inspections.
- Submit all required closeout documentation to the client.
- Obtain the Certificate of Substantial Completion.
Phase 5: 100% Completion – Final Closeout
