Who completes the inspection during an ongoing project to notify the owner of the substantial completion date?

The architect is typically the professional responsible for completing the inspection during an ongoing project to notify the owner of the substantial completion date. This role involves overseeing the project’s design and ensuring that construction aligns with the plans and specifications. The architect's familiarity with the project and their obligations under the contract make them well-suited to determine when the construction work is sufficiently complete to allow the owner to occupy or utilize the building for its intended purpose.

Substantial completion is a crucial milestone in the construction process, as it signifies that the work is mostly finished and the owner can take possession of the project, though minor details may still need to be addressed. The architect's authority and expertise in assessing the project conditions validate the substantial completion status, ensuring that all requirements have been met from a design perspective.

In contrast, while engineers, inspectors, and project managers play valuable roles in the construction process, their focus may differ. Engineers may handle specific technical aspects and systems, inspectors typically ensure compliance with codes and regulations rather than project completion status, and project managers oversee the overall progression of the project, including scheduling and resource management. However, it is the architect's responsibility at this stage to formally notify the owner regarding substantial completion.
