Which document typically outlines the roles and responsibilities of team members in a design-build project?

The most appropriate document that outlines the roles and responsibilities of team members in a design-build project is the project contract or agreement. This document serves as the foundational legal framework for the project's execution, detailing the expectations, obligations, and authority of each party involved. Within a design-build context, it clarifies the integration of design and construction responsibilities, specifying how the design-builder will collaborate with all stakeholders, including owners, architects, engineers, and subcontractors.

The contract or agreement ensures that everyone involved understands their specific roles, from project scheduling and budget management to quality control and communication protocols. It also includes terms related to dispute resolution, changes in scope, and performance criteria, which are vital for maintaining alignment and accountability throughout the project lifecycle.

In contrast, other documents such as the project handbook, preliminary design report, and project feasibility study serve different purposes. The project handbook often offers guidance on procedures and policies but may not define responsibilities in the same structured manner as the contract. The preliminary design report focuses on presenting initial design concepts and assessments rather than outlining roles. Lastly, the project feasibility study evaluates the project's viability and financial implications, without detailing team member responsibilities.
