In the context of fees, what does CA represent?

The correct answer is indeed related to Construction Administration, which refers to the services an architect provides during the construction phase of a project. This phase is crucial because it ensures that the project is executed according to the design intent and specifications outlined in the contract documents.

Construction Administration includes tasks such as site visits to assess construction progress, responding to requests for information (RFIs) from the contractor, reviewing change orders, and processing payment applications. Through these activities, the architect ensures quality control and adherence to the project timeline and budget. The architect's role during this phase also involves communicating with all stakeholders, including the contractor and the client, to resolve any issues that may arise.

In terms of fees, construction administration services often represent a significant portion of an architect's overall remuneration for a project due to the level of involvement and responsibility required. Understanding this role’s importance is vital for architects in managing their practice and appropriately billing for their services.
