Which role within BIM involves coordinating logistics like site traffic and lighting?

The role that involves coordinating logistics such as site traffic and lighting is indeed the Contractor/Specialty Contractor. This party is responsible for the overall management of the construction site, ensuring that all aspects of the project are properly organized and executed. They plan and manage site operations, which includes not only the physical construction tasks but also logistics related to how the site functions on a day-to-day basis.

This includes developing strategies for site access, managing material deliveries and storage, implementing safety protocols, and ensuring proper lighting for both safety and work efficiency. By overseeing these logistical elements, the Contractor/Specialty Contractor plays a critical role in keeping the project on schedule and minimizing disruptions.

The other roles mentioned might contribute to aspects of the project but do not specifically focus on the comprehensive management of site logistics. The Owner/User may define project requirements but typically do not engage directly in site coordination. Engineers may design elements that affect site logistics but are primarily focused on technical and infrastructural aspects. Manufacturers/Suppliers supply materials but do not handle the day-to-day management of the construction site or site-specific logistics.
