ExAC Section 4 Practice Exam 2025 – Complete Guide for Canadian Architects

The primary disadvantage of a Turnkey project delivery method is that it often results in less control for the architect over the design. In a Turnkey project, the contractor is responsible for both the design and construction of the project, which means that the architect typically has limited involvement in the design decisions once the initial parameters are set. This can lead to challenges in ensuring that the project aligns with the architectural intent, as the contractor may prioritize aspects such as cost and schedule over the aesthetic and functional qualities of the design. Consequently, the architect's ability to influence the final outcome is diminished, potentially impacting the overall quality and vision of the project.

On the other hand, while higher costs, complex contractual relationships, and increased time and cost for approval are important considerations, they do not directly reflect the core nature of the Turnkey delivery method, which fundamentally centralizes design and construction within one entity, thus reducing the architect's role in these phases.
