Describe the key innovation and technology aspects of the project

Project Narrative

The Edith Green-Wendell Wyatt (EGWW) Federal Building Project modernized an existing 18-story, 512,474-square-foot office tower located in downtown Portland. Completed in 1974, the building’s MEP systems were worn out and out-dated. The project goals included upgrading building systems, updating work environments and improving accessibility, while also meeting the energy and water conservation requirements of the Energy Independence & Security Act (EISA), complying with federal standards for blast resistance, and providing new code compliant egress stairs, entries and rest rooms.
