  2. New U.S. Census Bureau Headquarters

  3. INTRODUCTION • 1.5 million square foot office space & 1.0 million structured parking, $400. million. • Bridging Design-Build Delivery Method The Team- Bridging A/E- SOM- DBC- Skanska (GC) &HKS ( Architect of the Record)- CM- DMJM / Heery ( Jt. Venture)- LEED consultant - Greenshape • Construction & Occupancy Completed, 2007.

  4. OWNER’S PERSPECTIVE • GSA wanted to achieve GSA's new Standard of LEED silver or higher. • Bridging Design-Build delivery method was new untested to achieve LEED. • SOM's Concept, which achieved 34 LEED points. • GSA Concerns : • - HKS's CD when completed may not get 34 LEED points • - DBC's design proposal may conflict with PBS P-100 • Benefits in having CM, and Bringing the CM on very early : • - To oversee LEED process and to track LEED points • - To perform and oversee additional commissioning ( Which achieved 1 LEED Point) until all equipment turnover • GSA saw Benefit in having DBC hire an Independent LEED consultant, Greenshape.

  5. GREEN IS GOOD ...there is no other building complex like this in the world • Designed to be the architectural expression of sustainability. • Set in an 80-acre woodland preserve. • Two buildings have been conceptually "Cleaved" from a single mass. • Central garden, courtyards, and other sustainable landscape gardens. • Woodland-facing facades are clad in a unique, architectural sunshade. • Parking structures green screens with climbing ivy. • Scenic views brought into the workplace. • "Mainstreet" with all kinds of amenities.
