39 A brief Overview from University Mechanical

40 Lessons Learned BIM Implementation Plan needed Software versatility & compatibility study needed Need to define BIM standard early in the process Team involvement for Visualization Aid

41 Communication with HPCC Model Manager and Detailers Third Party Modeler needs to contact HPCC Model Manager Face-to-Face Weekly Meetings with Third Party Modeler Talking with other HPCC personnel about the Courthouse Project Understanding QC Process from Third Party Modeler Commitment on Schedule Due Dates - Schedules and due dates were generated however the due dates were not achieved Knowing Manpower for Completing the Model on time and by the due dates Be specific on what is included for the Building 3D Model - The "granularity" needs to be defined in the proposal.

42 More Time Factor Upfront on Completing Items Decision Makers need to Attend Meetings to Determine Direction Decision Makers on Cost Analysis to Determine Total Cost Values Create Lists for Action Items from A/E and Subcontractors Engage Metal Stud/Drywall Subcontractor Layout of All Access Panels and Other Non-MEP Items

45 Great tool for using construction documents in Field More apps in development 3D Markups not yet available in market

46 Vela Mobile: Work to complete lists, Punch lists Dropbox: Cloud based storage, Misc. Documents GoodReader: Construction Documents, Shop drawings, Lift Drawings, Specifications AutoCAD WS: Lift Drawing markups Notes: General notes

47 ipad s in the Future 3D Model markups possible with more reliable and stable apps Autodesk developing 3D model based apps in 2013 Lessons Learned Staff training needed Develop standard protocols Total $$ spent: $31,000 Total Saved: man-hours!
