DC Water is planning to construct a series of tunnels over the next 15 years to capture excess sewer flow and convey it to the Blue Plains wastewater treatment plant. The major tunnel projects are: the 7.5 km x 7.3 m-diameter Blue Plains Tunnel (23,600 ft x 23 ft-diameter); the 4 km-long x 7.3 m-diameter Anacostia River Tunnel (12,500 ft x 23 ft-diameter); the 5.5 km-long x 7.3 m-diameter NE Boundary Tunnel (17,500 ft x 23 ft-diameter); and the 3.6 km-long x 4.8 m-diameter NE Boundary Branch Tunnels (11,300 ft x 15 ft-diameter). Proposals for the construction management services contract are under appraisal, with award expected in March, 2011. Three design-build companies have qualified for the Blue Plains Tunnels, and price and technical proposals are due 02.12.2010 with award expected in April, 2011 for construction start in July, 2011. A request for proposals for the Anacostia River is expected in early 2012. More from Ronald Bizzarri at DCWASA in Washington, e-mail rbizzarri@dcwasa.com.
