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.
