5 10 What is BIM? A Building Information Model (BIM) is a digital representation of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. A basic premise of BIM is collaboration by different stakeholders at different phases of the life cycle of a facility to insert, extract, update or modify information in the BIM to support and reflect the roles of that stakeholder. The BIM is a shared digital representation founded on open standards for interoperability. Approved March 1, 2006 NBIMS Exec Comm. 11 5

19 Getting to Placement of Work: CIP Design Modeled entire structure & exterior GFRP Coordination Designed and modeled all concrete embed plates for attachment of steel and precast Detailing & Constructability 38 Structural and Miscellaneous Steel Design RAM analytical model to start Tekla structural model SCI responsible for design and detailing of structural steel superstructure Participated in design team meetings starting at SD Extracted from model Supplementary contract documents Calculation package (similar to precast package) Designed for constructability Designed for GFRP panel compatibility 39 19

20 VDC and Placement of Work Process - Comprehensive Lift Drawings: For a self-performing general contractor, single most important factor for achieving Quality Productivity Centralized Information - over - many sources of fragmented information 40 Central Park Tower at Interlocken Real Results and Benefits 41 20

21 Project Benefits from the Process Earlier involvement in project commitments made at Schematic Design phase BIM as a process not just as a tool/software Overlapping of design and construction activities Accurate Tekla structural model maintained throughout design/construction phases Extracted supplementary structural drawings from Tekla structural model 42 Cast in Place Concrete Erection/Place Work Comprehensive lift drawings important to quality and productivity CIP performance Major improvement over fragmented sources: Reinforcing Precast embeds Structural steel embeds Miscellaneous steel embeds (elevators, stairs) Blockouts / penetrations 43 21

22 Cast in Place Concrete Benefits Construction Practically no approval comments from the EOR Zero RFI Reduced construction schedule two weeks 21.6% less reinforcing materials actual vs. budget (had three lump sump reinforcing bids) Estimated less than 0.07% waste in reinforcing material Less than 500 # s of reinforcing drop 358 tons of total reinforcing 44 RFI - Benchmark Comparison April Stories Completed on Schedule Village Center Station April Stories Ahead of schedule Central Park Tower 45 22

23 RFI - Comparison of Results from Similar Project Village Center Station Central Park Tower 44 RFIs CIP core walls: These RFIs accounted for 14.77% of total on project Cost range of RFIs $97,549 - $161,549 Zero RFIs in CIP core walls 46 Structural Steel Interactive Design Model / Detail Model Handoffs Prepare Structural CDs INTERACTIVE Structural Steel Shop Drawings by Enhancing Design Model Improve Delivery 40 Days 35 Days Total Review Steel Shop Drawings Review Steel Shop Drawings Fabricate and Deliver First Steel Package 47 23

24 Structural Steel and Misc. Steel Detailing Reduction in detailing hours 1,600 traditional as originally planned 1,050 hours actual Reduction attributed to correcting model at the correct stage 48 Structural Steel and Misc. Steel Fabrication Iterative, concurrent design / detailing processes Expedited fabrication start following CDs reduced by 56% (5 weeks) Reduced initial steel delivery time following CDs by 50% (8 weeks) 49 24

25 Structural Steel and Misc. Steel Erection/Place Work Where preceding work in design, detailing and fabrication bears fruit Only two RFIs (Structural Steel) Zero change orders in erection cost Clash Detection Clash Prevention Management 50 Structural Steel and Misc. Steel Benefits Design Facilitated shop drawing review process few review comments from all of design team Very efficient structural system 8.6# / sf Construction 39% savings in detailing cost $250k mill order savings to owner Reduced (nearly eliminated) RFIs 51 25

26 GFRP Exterior Panels (Glass Fiber Reinforced Polymer) Design/Coordination/De tailing & Fabrication/Placement Designed GFRP panels for fabricator Modeled outline of GFRP panels for coordination with structural frame Many conflicts were found during coordination prior to fabrication of GFRP panels 52 Trimble RTS Layout GFRP Layout Points for GFRP 53 26

27 Internal Benefits BIM in the Field Accurate Model Data Used Directly in the Field 54 CIP: 2 weeks ahead of schedule 21.6% of materials savings = $104,306 Zero RFI RFI Savings: 97, ,549 Steel: 8 weeks ahead of schedule $49,000 reduction in detailing costs $250,000 materials savings 2 RFI + 0 Change Orders Schedule: 10 weeks Costs: $600,
