What is the term used for the project's guiding design intent developed in Phase 1?

• A. Project charter
• B. Basis of design
• C. Construction schedule
• D. Risk register

Answer: (B)

The guiding design intent developed early in Phase 1 is captured in the Basis of Design. This document translates the owner’s program into concrete design criteria, performance requirements, and system descriptions that steer the entire project. It ties together codes, standards, and intended performance so the design-build team can make consistent, traceable decisions that meet the owner’s goals.

Why this fits best: the Basis of Design explicitly communicates what the project must achieve from a technical and performance standpoint, serving as the reference point for design decisions, selections, and evaluate-ability throughout the design phase.

Why the other options don’t fit as the guiding design intent:

• The project charter is about authorizing the project and outlining high-level objectives, not detailing the technical design criteria.

• The construction schedule focuses on timing and sequencing, not on design requirements or performance criteria.

• The risk register lists uncertainties and mitigation actions, not the design approach or performance goals.
