Tunnel Construction by a Mixed-Use Real Estate Developer

摘要

The Washington Navy Yard was, for over 200 years since 1799, a center for naval shipbuildingrnand outfitting. Today, a portion of the site is being redeveloped as a vibrant waterfront neighborhood by ForestrnCity Washington. DC Water’s Clean Rivers project required a 340 m (1,120 ft), 1.8 m (6 ft) inside diameterrntunnel beneath Tingey Street for control of combined sewer overflows to the Anacostia River. Forest Cityrnagreed to facilitate the Tingey Street construction since it has several projects being built concurrently inrnthe immediate area. The Tingey Street diversion sewer project put the developer, Forest City, in a significantrnproject coordination role for the publicly-funded USD $16 million tunnel. This paper describes how DC Waterrnand Forest City executed this fast-tracked, design-build project.
