Use BIM for Multiple Coordination

that can help make the process more successful and

improve the coordination between the disciplines:

Architectural, Mechanical, Plumbing, Electrical,Communications, Fire Safety and Security.



What Pro rams Can Be Used?• BIM/Revit/Autodesk/Navisworks

We do not recommend any one program asbetter than the other, just that you use one to

find the collisions/clashes

site for gathering information• Include items like details and actions required

(panels, racks, fiber, copper, coax, vertical wire

managers, horizontal wire managers, and labeling)• Identify and validate the cabling installed by quantity,

quality and correct locations

•Evaluate fiber copper backbones, overhead &vertical racking, core holes, fire-stopping, grounding
