The $230 million project will rise in the St. George section on the site of a former municipal parking lot.   The five story, 184,000 SF facility will house the New York State Supreme Court and the Richmond County Criminal courts, consolidating outdated court facilities now spread across four locations.

The program space included eleven supreme court rooms and three criminal court rooms, five hearing rooms, jury assembly and deliberation rooms, judges’ chambers and court offices.  The courthouse will be powered in part by building integrated photovoltaic panels and also offer three different green roofs.  It will also include a graywater system, public recreation space, and space for Staten Island’s green market.

HVAC system design included 1,050 tons of cooling with chillers and cooling tower, 525 boiler horse power hot water boiler plant, outside air handling units, computer type air conditioning units, exhaust fan systems, and direct digital controls with building management systems.

Electrical system design included new 120/280V Con Edison vault, two (2) 3500A takeoffs, two (2) 4000A service switchboards, power monitoring system, automatic transfer switches, 1000 kW diesel driven emergency generator system in outdoor enclosure, underground duct banks, cable and conduit distribution systems, one (1) 1600A emergency switchboard, one (1) 250A optional standby switchboard, building-wide lighting control system with occupancy sensors and daylighting controls, lighting protection system, and fully addressable fire alarm system.

During the design stage, L&J analyzed loads, met with and corresponded with Con Edison to determine electric service options, and developed and analyzed concepts.  Based on the costs/benefits analysis, DASNY selected the 120/208V electric service option with a new transformer vault located on St. Mark’s Place.

Plumbing and fire protection systems included domestic water system, cold water, hot water and hot water return, sanitary waste and vent system, natural gas system, underground drainage system and sump pumps, and fire protection standpipe system including fire pump and sprinkler system.

This project received the Award for Excellence in Design, Public Design from the Commission of the City of New York.
