  1. AB 204-6 Flagship BIM Case Study:Designing and Building the New CENTCOM HQ Major Patrick Suermann Steve Cline Air Force Center for Engr and Env. Burns & McDonnell The views expressed in this presentation are those of the author and do not reflect the official policy or position of the US government or the Department of Defense.

  2. JICCENT HQ and HQ CENTCOM The views expressed in this presentation are those of the author and do not reflect the official policy or position of the US government or the Department of Defense.

  3. 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

  4. Introductions & Roles Patrick C. Suermann, PhD, PE, LEED® AP • AFCEE MILCON PM, BIM SME Background: BSCE USAFA 1997 MSCM Texas A&M University 2003 PhD University of Florida 2009 Project Role: • Initial BIM (and LEED?) Consultant • Transitioned to AFCEE PM and admin oversight

  5. Introductions & Roles Steve Cline, PE, LEED® AP • BIM Implementation Leader • Senior Structural Engineer Background: BSCE Purdue University 2002 MSCE University of Illinois 2003 Project Role: • BIM Advisor

  6. The CENTCOM Project Overview • CENTCOM Facts • Description: Four story structure with precast cladding • Usage: Central Command Headquarters • Location: Madill AFB • Square footage: 260KSF • Stakeholders: • CM: USACE-Mobile • A/E: Burns & McDonnell • GC: Clark Construction • Owner: CENTCOM

  7. The CENTCOM Project Story • Original Plan: FY 2007 addition with FY 2008 alteration • Bids 4X programmed amount • Scopes combined to create new HQ building • Adjacent JICCENT building was used as basis for design graphic depicting steel prices OR demonstrating market conditions OR showing original plan for addition and alteration.

  8. Existing Facility

  9. Shifting to MILCON plan

  10. Some Early Modeling – Notice same structure

  11. JICCENT nearing completion

  12. JICCENT/CENTCOM Comparison Highlights: JICCENT: $115M for 268KSF CENTCOM: $ 61M for 260KSF Deemed due to combo of factors: Market forces Repeat Partners BIM!

  13. 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."

  14. 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) High Performance Buildings (Fall 2009)

  15. A New Vision for CENTCOM • Envisioned as a “flagship facility for all of the Department of Defense” – Lt. Col. Jay Beam • Project goals include: • Flexibility for changing mission • Staff comfort • Architecturally appealing • Sustainable • Innovative

  16. 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

  17. 2D Toolbox Drafting Tools Autocad Coordination / Clash Detection Careful cross-discipline drawing review Facility Management Tools As-Built Drawings O&M Manuals BIM Toolbox Modeling Tools: Revit Architecture 2008 Revit Structure 2008 AutoCad MEP 2008 Coordination / Clash Detection Tool: Navisworks Facility Management Tools: COBIE? FM Desktop? Comparing Toolboxes

  18. Traditional 2D and BIM Processes Compared • Access to Information • Understanding of the Facility • Clash Detection • Level of Detail • Duplication of Data

  19. 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…

  20. Model Progression Specification

  21. 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?

  22. Level of Detail: 2D vs. BIM Approach

  23. A BIM Set Apart: Describing the Level of Detail • Architectural and Structural models included • Wall stud sizes • Parameter for final paint • STC and SCIF ratings • Architectural precast • Fall protection system False Joints in Precast Piles

  24. A BIM Set Apart: Describing the Level of Detail • AND MORE… • Wall placards • Fire ratings listed • Finish codes on ALL walls • Wall finish tied to room schedule • Handrails modeled • T.P. dispenser modeled with Bobrick model number!

  25. A BIM Set Apart: Describing the Level of Detail • Mechanical model included: • ALL pipes and fittings (except connections to faucets!) • Diffusers • Return Air Grills • All ducts • VAV boxes • Air handling units

  26. Pump Room

  27. A BIM Set Apart: Describing the Level of Detail • Electrical components: • Light fixtures • Electrical panels • Communication antennas • Switches? • Electric feeder?

  28. A BIM Set Apart: Describing the Level of Detail • So what wasn’t modeled?: • Thermostat and wiring • Structural connections • Electrical conduits smaller than 1.5”

  29. CENTCOM BIM Highlighting Mechanical

  30. Lessons Learned: Level of Detail • Extremely high LOD for FM • Hard to budget • Clearly define LOD early on

  31. Lessons Learned: Comparing 2D vs. BIM Labor Hours Time Graphic by: Patrick MacLeamy, FAIA

  32. Clash Detection & Collaboration

  33. Clash Detection Resolved Clash Piping Vs. Structural CLASH!

  34. Clash Detection & Collaboration Initial Clash Report March 2008

  35. Clash Detection & Collaboration December 2008 Clash Report

  36. Clash Detection & Collaboration Final Clash Report

  37. Lessons Learned: Sharing the Model • Valuable at multiple stages • Clients able to make better informed decisions • Can have unforeseen consequences

  38. Achieving LEED Goals • LEED Gold • 25% Energy Reduction • Ultra Low-Flow fixtures and sensors • Daylight Controls • 42 LEED Credits

  39. The Next Phase: Construction Model Elements With No Fabrication Model Clark Construction Burns & McDonnell Design Team Facility Manager Fabrication Models: Steel, HVAC, Electrical, Plumbing, Fire Protection Design Intent Model As-Built Model Facility Management Model COBIE Spreadsheet With Matching Element IDs

  40. Lessons Learned: Choosing the FM Platform • Choose the FM platform upfront • Investigate compatibility with BIM platform • Identify how the FM tool will be utilized • Bi-direction integration with BIM Archibus™? FM Desktop™? Maximo™?

  41. Envisioning the Future of BIM • FM integration better defined • Level of detail standards • More content available • Contractors participating earlier

  42. BIM and IPD • Subcontractors onboard Day 0 • Participating in modeling • Sharing risk / reward Construction Photo 8/28/09 BIM (Constructed elements highlighted)
