On Thursday November 18, 2021, SK&A Senior Associate, Seth Rogge and Structural Engineer II, Megan Dulmaine attended the topping out party for 440 Penn.  Located in the thriving Union Market District in Washington, DC, the 12-story, 431,435 sf residential building includes 23,000 sf of retail and three levels of underground parking.  The challenge was to support the existing historic façade during construction and provide tie-in details to the permanent structure.
