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 partner with Turner Construction and Perkins&Will as Engineer of Record to deliver this unique design-build project. Structural engineering challenges included creating the unique folded plate roof, a world first using DLT (dowel-laminated timber). 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.
