Camino MOB MEP/FP Coordination Process
2.a. Design to Engineering Handoffs
1. Created a Pull schedule for Engineering and Design based on construction schedule
2. Agreed to work by quadrants to match the construction schedule
3. Worked backwards to determine the completion date milestone for Engineering and Design
4. Used Navisworks to identify and resolve conflicts

Coordination and Conflict Resolution Process
Specific Examples – 1st Floor SE QuadScreenshot Screenshot from 1from 1stst Clash Clash Detection Detection session on session on 7/19/05 shows 7/19/05 shows multiple multiple clashes clashes between the between the Sprinkler main Sprinkler main and supply and supply ducts on south ducts on south side. It was side. It was decided to decided to move the main move the main to correct the to correct the issueissue

Coordination and Conflict Resolution Process
Specific Examples – 1st Floor SE Quad
Screenshot Screenshot from 2nd from 2nd Clash Clash Detection Detection session on session on 7/26/05 7/26/05 shows that shows that the Sprinkler the Sprinkler main was main was moved and moved and clashes with clashes with supply ducts supply ducts on south on south side have side have been been resolvedresolved

Camino MOB MEP/FP Coordination Process
4. Lessons Learned• Design Team wanted to hold Engineering
(detailing) work until Design was complete for the whole project
• At the outset had an agreement between Design and Engineering Team on how the Detailed Engineering models would be developed (By Quadrant)
• Engineering team expected design released by quadrant, which did not happen for the first 4 quadrants
-
17
Lessons Learned
Possible Solutions
• Solution that we could have delayed the Engineering work until we were confident that enough Design info was available
• We could implement handoffs by system (Plumbing / Mechanical) rather than by Geographical Areas (Quadrants)
-
18
Lessons Learned
Technology Solutions
• Every Detailer should have access to Clash Detection and Resolution software from the very beginning of the project (Not just the GC)
• Use a document collaboration system to share drawing and model files (No FTP)
