As representative for MTA/NYC Transit Authority (NYCTA) and Staten Island Railway, TECTONIC provided special inspections, quality control, independent laboratory materials testing, and environmental inspection / engineering services for the construction of a brand-new train station on Arthur Kill Road between Lion Street and Barnard Avenue on the Staten Island Railway system. The new station, now referred to as the Arthur Kill Station, replaced the Atlantic and Nassau Stations that were demolished as part of the scope of work.

The new Arthur Kill Station is a modern complex providing upgraded facilities and services, including:

• ADA-compliant ramps leading to full-length platforms
• An enclosed pedestrian overpass to access both platforms
• Windscreens with 28 large-scale glass panels featuring artwork by the artist Jenna Lucente at within the stair towers and the overpass
• Park and ride lot for 150 cars
• Station platforms and off-hour waiting areas with surveillance cameras
• Convenient transfers between the NYC Transit Buses and the Staten Island Railway trains

The project included the construction of new passenger platforms, canopied pedestrian overpass, landings, stairs and ramps, lighting, signage, new parking lot, new street layout and sidewalk restoration, and a new network of water main, sewer and drainage system.

Responsibilities included quality control inspections and materials testing of earthwork, backfill, borings, paving and utilities, cast-in-place and precast concrete, masonry, structural steel, exterior insulation and finish systems (EIFS), fireproofing, etc. Geotechnical inspection responsibilities included piles, earthwork, underpinning and subgrades. Duties included preparation of daily, weekly and monthly inspection reports, attendance at progress meetings and liaison with MTA NYCT, SIR, and Capital Construction representatives

Tectonic was also responsible for Soil Erosion and Sediment Control (SESC) per SWPPP and NYSDEC Permit; and provided environmental waste characterization services which involved collecting waste samples at the site and analytical testing. The new complex generated approximately 6,000 cubic yards of soils that required off-site disposal. The analytical test results were compared to the Soil Clean-Up Objectives (SCOs) set forth in 6 NYCRR Part 375. -6.8(a) and (b) (Part 375) and the Supplemental Soil Clean-up Objectives (SSCOs) set forth by the New York State Department of Environmental Conservation (NYSDEC) Final Commissioner Policy, CP-51 (CP-51). Additionally, soils were compared to 6 NYCRR Part 371.3 (e), Table 1 (Part 371) for classification of hazardous waste.
