What function does the Project Manager serve during the construction phase?

The Project Manager plays a critical role during the construction phase by overseeing the execution of the project to ensure that it is completed on time and within budget. This involves coordinating various aspects of the construction process, including managing resources, scheduling activities, communicating with stakeholders, and mitigating risks that may arise during construction. The Project Manager's ability to keep the project on track in these areas directly impacts the overall success of the project, as delays or overspending can lead to significant consequences.

The other roles described do not align with the Project Manager's responsibilities during construction. Designing the project layout and aesthetic pertains to the architectural design phase rather than project management. Marketing and promotion of architectural services fall under business development or marketing roles, which is outside the scope of construction management. Conducting historical research on architectural styles is related to academic or design research and does not involve the coordination necessary for project execution on a construction site.
