Class description and key points l.jpg

Class Description and Key Points

  • Class Description

    • This session will discuss the new premiere building for the Department of Defense's most dynamic Command—Central Command. This LEED-Silver facility will be the first of its kind on Mac Dill AFB. Building on design efficiencies gleaned from the facility's fraternal twin, the JICCENT HQ, this building offers a myriad of lessons learned when moving to a BIM-based approach for a design-bid-build project with multiple stakeholders

  • Key Learning Points

    • Compare 2-D traditional design with a BIM-based approach

    • Realize the benefits and challenges of moving to BIM in the federal government

    • Apply anecdotal knowledge to future BIM-based design and construction

    • Understand BIM in relation to LEED®, collaboration, ATFP, and security concerns

    • Learn about the current state of the art for future shifting client expectations

A Pathfinder Project – Determining the ‘Knowns’

"We know there are known known's: there are things we know we know. We also know there are known unknowns: that is to say we know there are things we know we don't know. But there are also unknown unknowns — the ones we don't know we don't know."

Burns & McDonnell: A “Known Known”

  • 100% Employee-Owned

  • FORTUNE Magazine’s 100 Best Companies to Work For

  • $1.1 Billion+ in 2008 Revenues

  • Founded 1898

  • 3,000+ Employee-Owners

  • Energy Star rated HQ (working towards LEED Silver)

  • Project goals include:

    • Flexibility for changing

      mission

    • Staff comfort

    • Architecturally appealing

    • Sustainable

    • Innovative


Achieving the vision l.jpg

Achieving the Vision

  • Synergistic Approach:

    • Bringing Designer, Owner, User and Facility Manager together

    • Utilize BIM to meet FM goals, compressed schedule

    • Sustainability through LEED Gold

    • Innovative goal of carrying BIM through to FM

Traditional 2d and bim processes compared l.jpg

Traditional 2D and BIM Processes Compared

  • Access to Information

  • Understanding of the Facility

  • Clash Detection

  • Level of Detail

  • Duplication of Data


Defining the level of detail l.jpg

Defining the Level of Detail

  • Critical for success of BIM as FM tool

  • BIM vs. 2D

  • The FM Software question

  • Start by thinking like a facility manager…

Model Progression Specification


Level of detail thinking like mike lilya l.jpg

Level of Detail: Thinking like Mike Lilya

  • Focus on creating flexible space:

    • Which walls have SCIF or STC ratings?

    • Are there critical MEP or Structural components in the wall?

    • What VAV box serves this space and where is it located?
