"480 feet long. By 1900, the building that preceded Building 109 had been expanded for uses that included a plate shop, restaurant and offices, mold loft and plate bending shop and tool room. The Todd Shipyards General Plan identifies Building 109’s use as an angle and boiler shop, sheet metal shop and tool room. The mold loft was an important component to the operations of a shipyard. The size of a shipyard’s mold loft was the measure of the size of the vessels they were able to produce. A large clear span area was needed to transfer plans for ships to a life-size, two-dimensional pattern half-hull located on the floor.This is a one-story metal warehouse, essentially rectangular, with a slight “L” at the eastern end. It is clad with corrugated metal and has steel sash windows. The building has an irregular roof line."
