DC Southwest Library
An Exposed and Expressive Signature Timber Structure
PROGRESS UPDATE: Timber construction is complete! Stay tuned for overall completion this Fall.
We were excited to be on the design-build team with Turner Construction and Perkins&Will delivering this unique design-build project. As Engineer of Record, we worked closely with the City to permit this unique project - using DLT to achieve a world-first folded plate mass timber roof. This is our second project in Washington D.C., following the Arena Stage project, and is the Capitol's first all mass timber building. We also provided timber construction services for the superstructure, including the folded plate DLT (dowel-laminated timber) roof supported by a Glulam / Steel substructure and a hybrid timber and steel braced frame. We are excited to see Perkins&Will's beautiful design vision realized for this warm, inviting community space.
