From STLtoday: O’Fallon, MO-based SAK Construction LLC has begun work on a $9.2 million contract to rehabilitate 5,575 linear feet of aging combined sewer in downtown St. Louis.
The project, which includes a major segment of the brick-and-limestone Old Mill Creek sewer, is jointly funded by the U.S. Army Corps of Engineers and the Metropolitan Sewer District of St. Louis. The sewer was built in the 1860s.
The project includes renovating the 18-foot-high by 20-foot-wide arch-shaped sewer, 15 manholes and 58 lateral connections. An estimated 3,200 cubic yards of concrete, 4,500 cubic yards of shotcrete and 400 tons of reinforced steel will be required. Completion is scheduled for November 2017.
