Summary of Greenburgh Police Department Parking Lot Retaining Wall Bid Plans

This document comprises the bid plans and specifications prepared by BBS Architects, Landscape Architects and Engineers, PC for the Town of Greenburgh Department of Public Works, specifically for the Greenburgh Police Department Parking Lot Retaining Wall project located at 188 Tarrytown Road, White Plains, New York. The project generally consists of the removal of a failing wood retaining wall, construction of a modular block concrete retaining wall (manufactured by Redi-Rock or approved equal), concrete and asphalt paving, drainage utilities including storm drain piping and a drainage manhole, vinyl-clad chain link fencing with gates, and miscellaneous site work. The work encompasses erosion and sediment control measures, demolition of existing structures and vegetation, grading and drainage activities, site details including concrete curbs and sidewalks, and final stabilization and seeding. The plans indicate that all construction equipment must work from the parking lot side of the wall, with no equipment permitted on the pond side. The project is identified under file number 25-278 with an engineer's certification dated September 8, 2026, and the plans are set to expire March 31, 2028.

The plans specify detailed construction requirements including the installation of precast concrete modular block retaining walls with varying heights ranging from approximately 4 feet to 10 feet maximum, structural fill with #57 bluestone, 4-inch underdrains with filter fabric, and leveling pads as required. Erosion and sediment control measures are mandated throughout construction, including turbidity curtains 5 feet from the water line, silt fencing, temporary plastic barrier fencing, compost filter socks, stabilized construction entrances, and inlet protection. The contractor is responsible for all sheeting, shoring, and dewatering operations with dewatering filtered through sediment bags before entering the stormwater system. No indication of contract award dates, pricing information, or incumbent contractors is provided in the bid plans. The document notes that no business enterprises have been awarded an identical or substantially similar procurement contract within the past five years.
