Prepared by the Engineers Joint Contract Documents Committee (EJCDC).

D-625, Certificate of Substantial Completion—Design-Build, is a vital document for design-build projects, providing a formal record of the date when construction or a designated portion is deemed ready for its intended use. It outlines the responsibilities of the Owner and Design-Builder post-completion, including property insurance, utilities, site security, and maintenance, while also establishing a punch list for remaining tasks. The document ensures compliance with contract provisions, marks the start of the correction period and warranties, and allows for amendments to responsibilities through mutual agreement. Designed for flexibility and customization, D-625 is an essential tool for efficient project management and accountability in design-build contracts.

EJCDC includes the American Society of Civil Engineers, the American Council of Engineering Companies, the National Society of Professional Engineers, and the participation of more than fifteen other professional engineering design, construction, owner, legal, and risk management organizations.

EJCDC documents are delivered in Microsoft Word format (file extension *.docx) and sometimes Microsoft Excel format (file extension *.xlsx). Microsoft Word and Excel are required if you wish to edit the files.
