Final answer:
The Project Manager is generally responsible for overseeing all aspects of a construction site, ensuring the project is completed according to plan. This role is akin to that of a technical director in a production environment, managing the set building and overall safety.
Step-by-step explanation:
The employer that has the overall responsibility for construction at the worksite is typically the Project Manager. The Project Manager plays a central role in coordinating and managing different aspects of the construction process, which includes ensuring the work is completed to specifications, within budget, and on schedule.
This role is similar to the responsibilities held by a technical director in a production setting, who oversees the set building and production safety. They both share the duty of overseeing the proper execution of a project, although in different environments and with different teams.
