Project Profile

In Oregon, the U.S. General Services Administration (GSA) owns 19 buildings that serve as office space for thousands of federal workers. As one facility within the agency’s 100 buildings in the Northwest/Arctic Region, the modernist 911 Federal Building in NE Portland was constructed in 1953 by the Lloyd Corporation. Much like the BPA 905 Building (also operated by GSA), 911 has undergone significant facility infrastructure upgrades which meet Energy Star requirements and include an expansive green roof.

A natural upgrade to a modernist form.
Originally the home for the Bonneville Power Administration until 1987, the 911 Federal Building is a structure truly dedicated to performance. Spanning two city blocks, the agency estimates energy audits and upgrades have resulted in nearly $70,000 in annual energy savings since 2009. For this upgrade, Snyder removed the existing roof and improved the insulation R-Value to an R36 average. We installed a Garland 2-ply SBS hot-applied roof system, replaced counterflashing and installed a 13,200 sq. ft. ecoroof. Because we had installed the last roof in 1993, Snyder was familiar with the legacy roofing system and designed the most efficient process for replacement.
