G. M. Standifer Construction Company
The G. M. Standifer Construction Company was an American company that built three shipyards on the Columbia River for the World War I effort, one in Oregon and two in Washington. After the war it maintained its original yard in north Portland, Oregon. The north Portland yard, and one of the Vancouver, Washington yards produced wooden ships. The other Vancouver yard, located just west of what was then the Spokane, Portland and Seattle Railway bridge produced steel-hulled ships. The Portland yard was located about a mile to the west, just downstream from the BNSF bridge. Both Vancouver yards were closed in 1921.
