29 Ryerson

We are working with the team to reposition this former manufacturing into an office and retail space. The project includes adding three floors to the existing eight-floor building (29 Ryerson) as well as a new three-story building (256 Flushing) connected by a three-story glass atrium. The development also includes two below grade parking levels. Although the buildings are connected, they are being designed with entirely separate MEP/FP systems due to zoning laws. We are designing all new utilities, drainage, power, gas, fire and sanitary services for both of the buildings.

The mechanical systems we designed for 29 Ryerson include two 500-ton air cooled cooling towers with a 6.5 million BTUH gas fired boiler plant to provide heat pump units for all areas. For 256 Flushing, we designed a VRF (variable refrigerant flow) system including a condenser farm on the roof and heat recovery. The different systems meet the developer’s design goals and provide flexibility for marketing/leasing the spaces.

Our electrical team designed a new 120/208 volt ConEdison service for each building, a new life diesel fuel oil safety generator with all new and flexible electrical distribution for life safety and normal power throughout. We designed a new digital addressable fire alarm system for both buildings, all new fire pumps, fire services, new standpipe systems and new sprinkler layouts.
