Todd's presence in Puget Sound began in 1916 with the acquisition of Seattle Dry Dock & Construction Company, which in 1911 had acquired Moran Bros., which had been building and repairing ships in Seattle since the 1880s.  The yard was at the foot of Charles Street on the Seattle waterfront.  In May 1918, Todd sold this yard to the Emergency Fleet Corporation, which combined it with the adjoining Skinner & Eddy yard, and bought property for a repair yard on Seattle's Harbor Island and for a construction yard in Tacoma's Commencement Bay.  A contract from the U.S. Navy for three cruisers was transferred to the Tacoma yard and Skinner & Eddy (qv) completed the work that was in progress.  Todd acquired additional property on Harbor Island in 1940 in order to create additional construction capacity.  This yard, which was designed to build destroyers and was built with $9mm from the Navy, employed 17,000 people at its peak, while the repair yard employed another 5,500.  After the war, Todd acquired the new facilities from the Navy and the combined yard remains in operation today, as Todd's sole remaining shipyard.  It retains new construction capability but is now essentially dedicated to the repair business.  See the shipyard from the air on Google here.
