DBIA Project Closeout and Commissioning

Question 1

Substantial completion in a design-build project is best defined as the point when:

Accepted Answer

The project is sufficiently complete so the owner can occupy or use it for its intended purpose

Answer

Substantial completion is reached when the project—or a designated portion—is complete enough under the contract for the owner to occupy or use it for its intended purpose. This milestone typically triggers the start of warranty periods, transfer of insurance responsibility, and release of retainage, even if minor punch list items remain.

Question 2

Which document, typically generated during final inspection near project closeout, lists remaining minor deficiencies the design-builder must correct?

Accepted Answer

Punch List (Deficiency List)

Answer

A punch list (also called a deficiency list or snag list) catalogs remaining incomplete or deficient items identified during final walkthrough. It is jointly developed by the owner and design-builder and must be resolved before final payment is released. It is distinct from the certificate of occupancy, which is a regulatory document issued by the authority having jurisdiction.

Question 3

Commissioning in a design-build project primarily involves:

Accepted Answer

Verifying that building systems are installed, tested, and operating per the owner's design intent

Answer

Commissioning is a systematic quality process that verifies mechanical, electrical, plumbing, controls, and other systems are installed correctly, functionally tested, calibrated, and performing per the Owner's Project Requirements (OPR). It bridges construction completion and operational readiness—distinct from permitting or procurement activities.

Question 4

As-built (record) drawings prepared at design-build project closeout are primarily valuable because they:

Accepted Answer

Document actual constructed conditions for future maintenance, renovation, and emergency response

Answer

As-built drawings record how the project was actually built—including deviations from the original design made during construction. They are essential reference documents for owners, facility managers, and future project teams who need to understand existing conditions for maintenance, operations, emergency planning, and future renovations.

Question 5

In design-build contracts following DBIA model language, the contractual warranty period for the completed work typically begins at:

Accepted Answer

Substantial completion

Answer

Warranty periods—both statutory and contractual—commence at substantial completion, when the owner begins occupying and using the facility. This is standard in DBIA model agreements and aligns risk with actual use: the owner begins depending on the facility's systems at substantial completion, so that is when protection should begin.
