Metropolitan Transportation Authority (MTA) Capital Construction retained Schiavone Shea and Kiewit (SSK) Constructors JV for construction of the 72nd Street Station for a new Second Avenue Subway line in New York City, New York. The project scope includes the extension of shafts to a previously-bored tunnel, the construction of caverns for the station, and relocation and temporary support of utilities. Distinct Engineering Solutions, Inc. (DESI) provided SSK with environmental engineering support, including preparation of the Historical Resources Construction Protection Plan, air & noise monitoring and modeling, and selection of muck house materials to control air and noise pollution levels of the project. DESI conducted hazardous material surveys for asbestos, lead-based paint, and PCBs, and prepared several plans as part of environmental management, and assisted SSK with implementing them. DESI provided environmental awareness training, characterized subsurface soil & groundwater, and prepared the Community Air Monitoring Plan, the Exposure Monitoring Plan, the Pollution Prevention Plan, and the Soil Erosion Prevention Plan. A Historical Resources Construction Protection Plan was developed for 21 buildings within 200 feet of construction. DESI developed a Noise Control Monitoring and Mitigation Plan, installed the noise monitoring equipment, and evaluated noise levels generated by both on-site and off-site construction equipment. DESI performed baseline air & noise monitoring, and developed site-specific limits. DESI was also involved in groundwater sampling, pretreatment and management, and establishing procedures to surpass sustainability requirements. Continuous air and noise monitoring was performed on a real-time basis, with submission of weekly and monthly reports. DESI performed simulation studies and modeled noise propagation, identified materials to control noise outside of the muck house, and incorporated dust suppression mechanisms into the muck house operation to control air pollutants. This project won an American Council of Engineering Companies (ACEC) of NJ 2013 “Distinguished” Engineering Excellence Award.
