Fred Williams Mechanical Coordination Department is using the latest AutoCad MEP 3D software and Navisworks Manager to model, coordinate and detect clashes in our mechanical systems. Using these tools allows us to collaborate with architects, engineers, general contractors, owners, and other trades to provide an efficient building model. The BIM (Building Information Modeling) process helps us at Fred Williams produce realistic views, reduced coordination time and to communicate conflicts, as well possible cost saving solutions.
