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

EJCDC® D-523, Construction Subcontract—Design-Build is a comprehensive contract template designed to establish agreements between Design-Builders and Construction Subcontractors. It defines the scope of subcontracted work, compensation methods (stipulated sum, unit prices, or cost-plus-a-fee), and includes provisions for safety, insurance, bonds, indemnification, dispute resolution, and termination. The document ensures clarity and consistency in project execution, aligning subcontractor responsibilities with the overarching Design-Build Contract. It provides detailed guidelines for editing, customization, and compliance with legal and regulatory requirements, making it an essential tool for streamlined and professional project management in design-build construction projects.

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 *.doc). Microsoft Word is required if you wish to edit the files.
