Which of the following phases is NOT part of a design-build project?

In a design-build project, the typical phases include pre-design, design, and construction. Each of these phases plays a critical role in the seamless integration of design and construction processes, which is fundamental to the design-build delivery method.

Pre-design involves the initial planning and programming steps necessary to establish project goals, parameters, and feasibility. It sets the foundation for the subsequent phases. Following pre-design, the design phase focuses on developing and detailing the project, where the design-builder collaborates closely to ensure the design meets the owner’s needs while considering constructability and budget constraints. The construction phase then follows, where the project is built based on the agreed-upon designs.

Post-implementation, however, is not part of the design-build project phases. It typically refers to activities that assess the project after its completion, such as performance evaluations, feedback collection, and potential modifications or improvements. While these activities are essential in other project delivery methods or within an overall project lifecycle, they do not constitute a distinct phase within the design-build model itself. Thus, identifying post-implementation as an unrelated phase clarifies its absence from the core design-build process.
