RS&H provided a constructability assessment, Construction Time Determination (CTD) schedule, and Independent Cost Estimate (ICE) for this large urban project involving the construction of an 8 mi. extension to the NYCTA system. This unique project is located on the Staten Island borough of New York City and traverses through high density, single and multi-family residential, commercial, and heavy industrial properties. The alignment utilizedrailroad right-of-way, City Streets, commercial properties and portions of the New York City Harbor. The project included the conversion of 1.5 mi. of below grade railroad track bed, the retrofit and rehabilitation of an elevated 4,000 ft. long abandoned railroad viaduct, a tunnel built through an existing 850 ft. long warehouse, and the construction of 2 large bridges with the largest structure measuring over 3,000 ft. long above the Kill van Kull in the New York City Harbor. RS&H efforts had to account for all impacts from the project’s unique and challenging site logistics that required coordination with live rail lanes, surface street vehicle and pedestrian traffic, an array of public and private utilities, the United State Coast Guard, the Army Corps of Engineers, a minor league baseball stadium, port terminals, numerous government buildings along with hundreds of residential, commercial, and industrial properties. The project required the use of multi-staged on-site concrete batch plants along with difficult underground utility work and complex beam erection. RS&H efforts included monthly projections on the labor demands of the project as well as a monthly assessment on the number of trucks that would be needed throughout the 3-year project. The RS&H Project Controls Group was responsible for evaluating the preliminary design, identifying constructability issues, determining construction staging, providing a CPM schedule, and providing a detailed peer review of the project’s estimated costs.
