Chambers Street Reconstruction
As part of its initiative to improve and update Lower Manhattan's infrastructure, the New York City Department of Design and Construction (NYCDDC) launched the reconstruction of Chambers Street, located between West Street and Broadway in Lower Manhattan in 2010. This project contains the following elements: replacement of existing water mains with new 20" water mains; reconstruction of the existing sewer (relining, repairs, replacement: upgrades to the roadway drainage system); and the installation of the following elements: granite curbs, pigmented sidewalks, ornamental street lights, traffic signs, concrete road base, and asphalt concrete wearing courses. LiRo is providing resident engineering services for this major infrastructure project.
This project is one of the first "Joint Bid" projects issued by NYCDDC, which allows private utility work to be conducted in conjunction with other infrastructure work. This private utility work includes the reconstruction of deteriorated structures; the installation of new conduits, including spare facilities, to account for the future growth of the downtown area; and the replacement of old, cast iron gas mains with new plastic gas mains.
The project has presented numerous challenges which LiRo personnel have been able to meet. Chambers Street is a bustling Lower Manhattan Street, and is home to the Borough of Manhattan Community College campus, so conducting work, while maintaining traffic and pedestrian flow, is a major task. The project also requires significant coordination with government agencies, utilities, and private corporations, including the New York City Department of Transportation; Lower Manhattan Construction Command Center; New York City Department of Parks and Recreation; New York City Police Department; New York City Fire Department; New York City Department of Environmental Protection; New York State Department of Transportation; Con Edison; Time Warner Cable; and Empire City Subway. Since funding for this project has largely come from Federal Highway Administration funds, significant reporting requirements are a substantial part of the project's scope.
