5 BIM Strategies for Owners Make the impossible possible Project delivery strategy Get a better building Life cycle strategy

6 Make the Impossible Possible Form generation Custom programming Iterative analyses Custom Fabrication Requires high level of technology skills in project team

7 Project Delivery Strategy

8 CURT White Paper 1202 (2004) The Architectural/ Engineering (AE) Productivity Committee was convened by the Construction Users Roundtable (CURT) to address the perception of inadequate, poorly coordinated AE drawings and the resulting difficulties in the field Building owners, particularly those represented by CURT, regularly experience project schedule and cost overruns. As a result, CURT has directed this task force to evaluate how alternative processes namely, use of information technology combined with changes in project structure and delivery processes might address these issues.

9 Committee Recommendations Owner Leadership Integrated Project Structure Open Information Sharing Virtual Building Information Models

10 BIM Represents a Paradigm Shift in Project Control Before BIM: 30% of projects do not make schedule or budget - CMAA Industry Report 2007 Building owners, particularly those represented by CURT, regularly experience project schedule and cost overruns. - CURT WP % of materials used in the construction industry become waste - Movement for Innovation Industry Reports and Economist Magazine 2002

11 BIM Represents a Paradigm Shift in Project Control Before BIM: 30% of projects do not make schedule or budget - CMAA Industry Report 2007 Building owners, particularly those represented by CURT, regularly experience project schedule and cost overruns. - CURT WP % of materials used in the construction industry become waste - Movement for Innovation Industry Reports and Economist Magazine 2002 After BIM: Corrected upwards of 300 critical conflicts in model 25% MEP construction schedule reduction ZERO field coordination change orders No work stoppages (550 workers) due to coordination issues Increased off-site fabrication Improved Quality Improved Safety Decreased material waste

12 Why? Automated Drawing Coordination + Clash Detection Tools = Fewer Field Problems + Less Rework

13 Design Phase BIM Pilot 70,000 sq. ft. hospital addition Design/ build delivery BIM effort: Initiated by the GC Ran in parallel with 2D CAD approach GC s AE consultants worked in 2D KFA shadowed CD development in BIM

14 Issues Identified Through BIM At 100% CDs, 22 remaining coordination and constructability issues: Wheel Toilet Room D10 on Sheet A indicates that the west wall is Type 3B. The3B wall type extends to the bottom of deck. A large return-air duct bisects the wall overhead. Lower Level ceiling clarification - Section 2 sheet A3.12 shows horizontal 6 bridging with a 1 plywood deck 1-6 above the finished ceiling tagged as lay in. This causes a conflict with the 90 x72 OA duct above the corridor, not enough plenum space to accommodate the OA, the RA and SA ductwork below, piping and the first floor structural framing. A long section of SA duct on the Main Level between and parallel to E F and perpendicular to 7-8 doesn t have any diffusers or branch lines coming off of it. The wall between Therapy Room D7 & Kitchen D6 is dimensioned on Sheet A to both faces of the wall. Because of the wall thickness, the provided dimensions are not possible. Please clarify which dimension to hold. New elevation dimensions of the AHU and plan drawings do not match the schedule. Schedule does not appear to have been updated.

15 BIM Pilot Conclusions BIM use by the design team WOULD improve the work product Modelers immediately see Misalignment of structure and architecture Nonalignment of waste stacks from floor to floor Ducts bisected by walls to deck Misplacement of lighting and other fixtures Automated coordination of all model views Plans Sections Elevations Schedules

16 Construction Phase BIM

17 Widely Acknowledged Problems 30% of projects do not make schedule or budget - CMAA Industry Report 2007 Building owners, particularly those represented by CURT, regularly experience project schedule and cost overruns. - CURT WP % of materials used in the construction industry become waste - Movement for Innovation Industry Reports and Economist Magazine 2002

18 What Contractors Say The majority of cost and schedule overruns are due to lack of building systems coordination BIM, properly applied, can address these issues: Need accurate 3D model of structure and architecture MEP subcontractors must develop detailed 3D models Subcontractors must fabricate and install from those models Image source: Mechanical Inc.

27 Achieving Project Delivery Benefits What to do: Use BIM Develop a BIM Execution Plan for both Design and Construction Perform 3D interference checks Generate all drawings from the coordinated model Build to the model

28 BIM Requirements for Better Buildings

29 Define Better Indentify appropriate BIM uses Visualization (supports problem-solving) Energy analysis or broader sustainability assessment Cost analysis Programmatic compliance Custom fabrication from BIM Require iterative analyses during design Use automated checking of BIM models for conformance to design targets as appropriate

32 Computable Building Description In the past, every analysis or review required hours or even days of a person's time to comb through the documents and analyze the content BIM provides a computable building description that can be directly submitted to analysis

33 Computability & Standards BIM creates a computable building description, but a great deal of thought must be given to including in the BIM the specific information required for each analysis BIM standards are required: Not just formats or file naming Objects required Properties (attributes) to be included Terminology

34 Example: GSA BIM Guides

35 GSA BIM Guide Series 02

36 Making a Better Building What to do: Use BIM for specific purposes Select specific software tools Create appropriate BIM families and property sets Common object library Define frequency of iterations/deliverables Develop a BIM QC Plan Develop a BIM Execution Plan

37 BIM Requirements for FM, O&M

38 BIM for FM, O&M Many Owners have experienced BIM benefits in design and construction They are looking for similar benefits postconstruction Few are ready to use and maintain BIMs post-construction

40 Planning BIM Information Handover Information handover strategy What information packages do you need? When do you need them? Information requirements Contents of each package Data format Terminology Project Handover Plan (BEP) Combined requirements Responsibilities Timing of exchanges Implementation Technical approach Procedures Contractual terms Training for all team members Establish Handover Strategy Determine Requirements Create Handover Plan Implement Handover Plan Information Strategy Project Information Handover Plan

41 Doing this is very difficult! Look for existing standards

42 COBie Construction Operations Building Information Exchange COBie is based on the IFC Model View Definition for Facilities Management Handover COBie's focus is on delivering building information for facilities management, not geometric modeling Spaces Equipment In simplified terms, COBie is IFC in the form of an Excel spreadsheet

43 COBie Phased Delivery Phased delivery of project documentation Capture the information when it is created Source: ERDC Phase Required COBie Information Architectural Programming Contact details Facility naming Space and room data sheets Space layouts Space zoning Early Design Coordinated Design Construction Documents Construction Mobilization Construction 60% Complete Beneficial Occupancy Fiscal Completion updated previous phase information, as needed and Floors Space finishes Zoning and space allocations Architectural product schedules updated previous phase information, as needed and Mechanical, Electrical, Plumbing product schedules Building Systems Product data (SPie defines minimum product templates) Design document register Indicative sizes for spaces (optional) updated previous phase information, as needed and Submittal document register Assignment of component to systems Connections between components (optional) updated previous phase information, as needed and Updated submittal document register updated previous phase information, as needed and Manufacturer contact information for all approved submittals Model and Serial numbers on all installed products/equipment Components identified by tag or bar codes, as appropriate Installed product data (SPie defines minimum product templates) updated previous phase information, as needed and Updated space function and room area measurements Warranty, parts, and handover documents Operation and maintenance documentation Installed product data (SPie defines minimum product templates) updated previous phase information, as needed
