As the first commercial office building in Washington, D.C. to feature mass timber new construction, the 105,000-square-foot vertical expansion of 80M Street is a Class-A office property owned by Columbia Property Trust, Inc. The expansion space consists of two new floors and a habitable penthouse atop the existing 286,000-square-foot building located in the Capitol Riverfront District. The MMT factory manufactured all mass timber structural components and provided installation services. The pioneering project proved worthwhile, with more than half of the expansion already pre-leased.

The 80M project showcases three stories of architecturally exposed mass timber structure atop an existing 7-story high-rise building. In accordance with the new IBC 2021 Tall Wood Building Code Provisions, the glulam, CLT, and connection products were required to be two-hour fire-resistive rated. As the mass timber material supplier for the project, MMT delivered products that demonstrated safe fire performance through large-scale testing.

80M is the first commercial office building in Washington, D.C. to feature mass timber.
