The United States Army Corps of Engineers seeks a contractor to modify the West Breakwater in Houghton, Michigan, to prevent stamp sand from migrating into the channel. The work involves increasing the breakwater's height, adding filter material, and handling various stones and excavated sand. The primary construction will occur from STA 0+30 to STA 4+00, with an optional additional section. The project is unrestricted and involves rehabilitating a structure originally built between 1898 and 1933.
