Awards & Recognition

AWARD RECEIVED AT THE 13th ANNUAL SEA-MW AWARDS GALA

Rathgeber/Goss Associates received an award for a Renovation over $40 Million at the Structural Engineers Association of Metropolitan Washington’s Thirteenth Annual Gala,  held on March 2nd, 2019 in Washington, DC.

The newly renovated 2000 L Street, re-branded as Alexander Court, is a 750,000 sf project which consisted of a complete renovation and expansion of the existing 2000 L Street structure, including a four-level vertical expansion above the 8 existing office floors and 3 garage levels, and the creation of a new 12-story atrium adjoining the building to the adjacent property at 2001 K Street to create a Class A office building. The expansion is supported at the existing column girl and incorporated multiple setbacks to meet local building massing and zoning requirements. At the lowest underground level, 72% of existing footings were expanded to accommodate the new building loads. Mat foundations were added at the shear wall lateral system and atrium braced frame. The existing cellar level was strengthened using fiber reinforced polymer and bonded cast-in-place concrete to accommodate a chiller plant. New steel framing enclosed the top of the existing helical parking ramp to create a new loading dock. Level 1 was strengthened to accommodate new finishes and mechanical equipment. An exposed steel frame at the front of the atrium was designed to withstand significant lateral building loads and the new glass tension wall forces. One-third of the existing level 2 slab was removed to create a large two-story lobby space. All existing levels were strengthened to accommodate the new shear walls, and levels 4-8 received horizontal slab extensions. The existing roof was strengthened and repurposed to create the new level 9. Above level 9, new long-span composite steel framing was designed for the expansion.

Michael Goss was Principal-In-Charge and Paul White was Project Manager for the project.

Congratulations and thank you to all team members!
