Phase II work includes: design and construction of a new Maintenance of Way Administrative and Storage Facility on timber piles, a new Communications Building, an addition to the existing Material Distribution Center, and a new Gate House security building at the entrance to the MNR Harmon Shop site. Facility elements include reinforced concrete pile caps, grade beams, and foundations; concrete slab construction (the MDC required superflat FF=50, FL=30 floor tolerances); structural steel fabrication and erection; insulated architectural precast concrete panels (tinted and acid etched finish); three-coat Kynar insulated metal panels; SBS modified bituminous membrane roofing; skylights, translucent and tinted windows and curtain walls; and building identification signage. Interior work includes drywall construction; acoustical tile ceilings; VCT, carpeting, ceramic tile, and epoxy resin floor coating; pallet storage rack systems; office furniture; lighting; building electrical; fire suppression systems (sprinklers and FM-200 clean agent systems); plumbing; and automatic temperature controlled HVAC. Fork, turret trucks, and service carts were furnished to MNR. Phase II work also prepares the site for major facilities to be constructed in Phase III. These activities included demolition (buildings, 200,000, 1,000, and 550 gallon fuel tanks), site clearing, new 13.2 kV power distribution, new site storm drainage (including 4 Vortechnics water quality inlets and an 11,000 square foot StormChamber leaching field), relocation of monitoring wells, new domestic and fire water systems connecting to existing operating services, new sanitary drainage systems connecting to existing operating systems and the treatment plant, relocation and/or construction of new storage yards and structures, fencing and gates, roadway realignment, guide rail, pavement markings, and paving. This work occurred in the immediate vicinity of and adjacent to the operating rail yard and maintenance facilities. Maintenance and protection of vehicular traffic was necessary and construction was staged in order to minimally affect Metro-North operations. RCC procured a State Pollutant Discharge Elimination System (SPDES) permit and monitors the site through a Storm Water Pollution Prevention Plan (SWPPP). Rehabilitation of the A-31 Ossining substation includes demolition of electrical equipment; lead paint and asbestos abatement; building renovation; new 15 kV switchgear, mimic panel, SCADA (Supervisory Control and Data Acquisition system), and data concentrator based Remote Terminal Unit (RTU) with local control panel. RCC rehabilitated a maintenance pit in the Harmon Maintenance Shop and a new steel drop table system was furnished and installed with new locomotive/ coach car support equipment. Work was performed while Metro North forces repaired locomotives and coaches on adjacent tracks. It was a requirement of the Contract to develop and implement a Quality Management System Manual, site specific Health and Safety Plan, and commission fundamental building systems as well as commission the substation. Completed in April 2006.
