Final answer:
The technical director is in charge of coordinating the activities of the owner's construction forces with the work of each contractor, similar to a project manager on a construction site ensuring, that different specialists work together efficiently.
Step-by-step explanation:
The individual responsible for coordinating the activities of the owner's own construction forces with the work of each separate contractor is likely to be the technical director. In a theatrical production scenario, the technical director oversees the construction of the set and ensures the overall safety of the production, similar to how in a construction project, a director or project manager would oversee the coordination of various teams and contractors.
The technical director would work closely with all members of the production team, including the light board operator, sound board operator, and the run crew, in order to ensure a harmonious and efficient execution of the show. This role is analogous to a project manager in a construction site coordinating construction activities among different specialists to ensure timely and safe project delivery.
Additionally, similar to a factory situation where the factory owners find it easy and profitable to coordinate their activities, it's critical for the technical director to find efficient ways to collaborate with various contractors to meet the project's goals and maintain profitability.
