Washington – Salini Impregilo and The Lane Construction Corporation have won a $580-million contract to build the Northeast Boundary Tunnel (NEBT) project in Washington, D.C. The NEBT will be a large, deep sewer tunnel that will increase the capacity of the District’s sewer system, significantly mitigating the frequency, magnitude and duration of sewer flooding and improving the water quality of the Anacostia River. As joint-venture partners, Salini Impregilo and Lane’s S.A. Healy won the contract from the District of Columbia Water and Sewer Authority (DC Water). Salini Impregilo has a 30 percent stake in the joint-venture and Lane the other 70 percent. The NEBT is the biggest component of DC Water’s Clean Rivers Project. It will be 50-160 feet below ground and run 27,000 feet from just south of Robert F. Kennedy Stadium to the intersection of Rhode Island Avenue NW and 6th Street NW. It will be aligned to intersect the existing chronic flood areas along Rhode Island Avenue NW. (9colonne)
