Agenda

• Open BIM Standards • Impact of Failure to Communicate • Scope of BIM • Managing Cost – Leveraging Resources • Role of International Framework Dictionary • Consensus Process • National BIM Standard Core Document • Lessons Learned

National Institute of Building Sciences

• 1974 - Public Law 93-383, Sect. 809 • Bridge between Private and Public Construction • Non-governmental – Unique 501c3 Organization • Unique in that it represents all disciplines in industry • Board includes - Architects, Engineers, Contractors, Insurers, Unions, Manufacturers, Legal, Housing, Vendors, Owners, Consumers, State & Federal Government, Codes & Standards, and Testing

An Authoritative Source of Innovative Solutions for the Built Environment

Coordinating the Councils Councils and Programs of the Institute Share Knowledge in the WBDG and BIM

High-Performance Building Attributes Sustainable

• Energy Use • Water Use • Site design • Transportation • Materials

Aesthetics

• Architectural value • Connection to surroundings • Inviting

Safe/Secure

• Terrorism • Natural Hazards • Structural • Indoor Environmental Quality • Egress

Historic Preservation

• Maintaining character • Existing resources/materials

Functional

• Meeting occupant needs • Durable • Adaptation • Necessary services

Productive

• Necessary services • Inviting • Indoor Environmental Quality

Cost Effective

• Construction • Operation & maintenance • Occupants • Financing • Life-cycle costs

Accessible

• Disabled • Aging population • Obesity

Resilient

USC College of Cinematic Arts $175M Project – Phase 2 (~$50M ) Phase 2 of project completion scheduled was for early 2011, but it was delivered 4 months ahead of schedule and cost $6.4M less than anticipated .

Execution Planning

• Provides opportunity for partners to agree on outcomes.

Managing Cost

Reversing the Trend

SMART

Goal - Turn a stagnant or declining productivity curve to an exponentially improving one

2004 2008 2012 2014 2018 2022 2024 ….

We Must Change!

• NIST in 2004 identified $15.8B lost to lack of interoperability • $3 trillion industry with possible 30% waste • 40% of global raw materials are consumed by buildings • Facilities consume 40% of the energy • 65.2% of total U.S. electricity consumption • Facilities contribute 40% of the emissions • Facilities contribute 20% of land fills • U.S. is no longer the worlds largest consumer…but we did not slow down © 2011 National Institute of Building Sciences

Value of BIM

What is the cost of NOT doing BIM?

Documented ROI’s of: Project A: Project B: 36.7% 16.2% $13,083 $7,145 Project C: Project D: 376.0% 109.0% $201,125 $64,335 Project E: 1653.9% $3,453,221 Project F: 299.9% $665,700 See article by Dr. Raymond Issa, Pg 22 © 2011 National Institute of Building Sciences

Lessons Learned

Lessons Learned 1. Difficult to capture & change business processes 2. Need something for technocrat as well as practitioner 3.

People don’t seem to share naturally 4. Not a technical problem – cultural 5. Balance management and technical needs 6. Must break down silos 7. Must use rules of governance 8. Need criteria and examples 9. Hard to keep volunteers engaged 10. Takes a long time – journey not project © 2011 National Institute of Building Sciences
