1. 3D Coordination For Construction Projects

2. All trades must provide their shop drawings in 3d for this coordination to work efficiently Structural HVAC Plumbing Electrical Fire Sprinklers Etc.

3. Coordination process is done in the office rather than hours of deliberating in the GC’s trailer Coordination process is done in the office rather than hours of deliberating in the GC’s trailer Paper work is easily tracked, via e-mail and collision logs Paper work is easily tracked, via e-mail and collision logs Benefits of 3D coordination

4. Hold all trades responsible, if you don’t coordinate it, you get what’s left Hold all trades responsible, if you don’t coordinate it, you get what’s left And the drawings just plain look cool And the drawings just plain look cool Benefits of 3d coordination

5. Coordination Process Structural drawn in 3D, this gives all trades the base to work off of All trades should have a basic elevation to work from i.e., fire sprinkler has the first 12 inches above the ceiling, the electrical has 12 inches from deck, etc

6. Coordination Process Start from the top of the structure and work down from there Coordinating the HVAC is the toughest with all trades Once HVAC is coordinated with other trades the process becomes a little easier In most cases, the Electrical and HVAC will coordinate first then the plumbing and fire sprinkler last

7. Coordination Process Roof drains can and do cause problems with other trades especially when they are not coordinated properly.

8. NavisWorks NavisWorks is a 3D collision check program that can read AutoCAD drawings This program will find all collisions within a set of 3D drawings A collision log can be created to assist in the correction of the collisions

9. How the coordination Process will work using NavisWorks All trades will Provide their CAD drawings to the company responsible for coordinating the project Then the responsible party will create a collision log with a list of the collision and a collision number (see next slide) and a drawing showing the location of the collision.

10. Collision Log

11. How the coordination Process will work using NavisWorks Each respective trade will return to their drawings and coordinate with the other trades until the collision has been cleared The drawings will be re-distributed and another collision check will be done until all collisions have been cleared

12. Examples of NavisWorks in the real world applications
