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.interoperability

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

Real Results and Benefits
41
20 1/8/2012
Project Benefits from the Process
Earlier involvement in project – …BIM as a process not commitments made at Schematic just as a tool/software Design phase 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 1/8/2012
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

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 1/8/2012
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 1/8/2012
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
