Substantial completion is dated and certified by which parties?

• A. City Building Official
• B. Contractor, Architect, Engineer, and Owner
• C. Project Manager and Owner
• D. Architect and Contractor

Answer: (B)

Substantial completion marks the point when the project is sufficiently complete in line with the contract documents to allow the owner to occupy and use it for its intended purpose. The date is formally given after a thorough inspection and is certified by the key actors who represent design, construction, engineering, and ownership: the contractor confirms that the work is complete and ready for use, the architect verifies that the work conforms with the contract documents and issues the certificate, the engineer confirms that the essential systems and structural components are ready, and the owner acknowledges acceptance and takes possession. This four-party sign-off ensures that design intent, construction quality, system readiness, and owner readiness all align, and it provides a clear milestone that affects warranties, risk transfer, and the start of any punch-list or liability periods. A city building official handles code compliance and occupancy permits, not the contractual milestone certification; relying on only two parties or excluding engineering or the owner would leave aspects of design verification, system readiness, or acceptance unaddressed.
