NYCDEP Croton Water Filtration Plant

The most unique aspect of the project is that the facility will be built completely underground. Construction of the facility will require two major underground construction phases: site preparation and tunneling. Each phase requires specialized expertise by both the contractors and the construction management team. The complexity includes the fact that a massive rock excavation must be undertaken before subsequent stages can begin, and tunnels must be completed before the plant can go on line. These contracts have particular risk because they are subject to unanticipated or unknown rock conditions. Delay in either one of these contracts will delay the entire project. 

As a part of the CM Team, Techno is providing many tasks including examining the construction of structures and sewer, water, and electrical systems, to ensure compliance with contract requirements and local building codes, management of the construction of the New York City DEP Resident Engineer’s Field Offices, Construction cost estimating, testing of main excavation rock bolts, monitoring rock blasting and excavation, reviewing payment requisitions, reviewing of time and material reports. Collecting as-built data, supervision of the implementation of Best Available Technology (BAT), on non-road diesel powered construction vehicles as required by the City of New York’s Local Law 77.
