520 East 72ND Street

520 East 72nd Street consists of a 192,939 SF, building with an 18 story tower on 72nd Street and a 13 story tower on 71st Street. There are 252 residential units. Originally constructed in 1964, the Hospital for Special Surgery occupies approximately 5,000 SF of one floor of the building while most of it remains a multifamily co‐op. The base building mechanical systems consist mainly of a 280 ton Trane steam absorption chiller that delivers chilled water during the cooling season and a cooling tower for heat rejection.

DM Engineering was engaged by the property manager to provide a cost-effective and reliable engineering solution. The design encompassed the removal of the existing system and installation of (2) new chiller double compressor Daikin Magnitude magnetic bearing centrifugal chillers–which proved to be extremely energy-efficient with excellent part-load performance. Additionally, DM designed the upgrade to the heating hot water system and the integration of all the systems into a new building management system.

The project also included a rigging path to the basement. DM Engineers worked with the manufacturer and structural engineer to customize the tubes in order to rig the equipment

The electrical engineering scope of work included the service request for a new feed from Con Edison, demolition all feeders serving existing chillers, and replacing them with a new service and transformer to accommodate the new equipment load.

2680 Morris Ave

This building will be located in the heart of the Bronx and have residential, commercial, and community facility areas. DM Engineers developed the mechanical, electrical, plumbing, and life safety engineering design for this new building.

The systems will include condensing boilers, packaged terminal air conditioners, variable refrigerant systems, fire pumps, and independent electrical distribution.

The second floor of the building is planned as an ambulatory health care facility; DM engineers develop all the required medical infrastructure required to accommodate patients

5 Pointz Towers

5Pointz is a new skyline complex construction located in Queens’s Long Island City neighborhood. Situated at 22-44 Jackson Avenue, the building contains 1115 units at 48 stories (two residential
towers rising above a common 5 story podium). The building’s amenities include: Basement storage,
bike room, children’s playroom, courtyard, event room, fitness center, game room, laundry room,
lounge, on-site parking, pet grooming / pet services, pool, Racquetball and basketball courts.

The connection podium will include: Enclosed commercial garage, Art Gallery & Artist Studios.
DM Engineers in partnership with Praxis Work Shop Inc. acted as the applicant of record & owner
representative assisting in the final stages of this monumental construction. Our team’s involvement
was crucial in attaining the approvals for occupancy from the diferent New York City’s regulating agencies. Among the construction administration support, our team assisted the project manager in
providing clarification of construction documents, performed site visits as appropriate to monitor the
progress of the work at regular intervals to determine whether the work is in accordance with the construction documents, provide revision of construction documents, verify the contractor request for
payment and kept the owner informed of the status of the project and guard against deficiencies in the
work, lastly DM assisted the project manager in reviewing the status of construction to determine the dates of substantial completion and final completion.

90 Greene Street

DM Engineers performed the mechanical, electrical, plumbing, fire protection & structural design services for a this high-end luxury apartment upgrade in the Soho area of New York City. Some of the features include a conversion of the apartment into a duplex living space with beautiful high ceilings and integrated controls.

The main challenge for this project was to integrate a state of the art engineering systems into a landmark building, where preservation is essential to keep the property’s value and history.

As an additional service to the building owners, DM Engineers performed a full building property assessment in order to develop a capital master plan to improve any deficiencies and help this historical building to continue its development.

The Park Mansion

The Park Mansion is a 1900, six story building by the architecture firm of Janes and Leo, reimagined as a luxury condominium offering full-floor 3-4-bedroom residences, lobby attendant, fitness room, private storage and bicycle storage.

DM engineers performed the Mechanical, Electrical, Plumbing, Fire Protection and Fire Alarm design of this repurposed building in the heart to New York City. HVAC scope included dedicated variable refrigerant flow units, perimeter hot water system, exhaust systems and dedicated systems for common/ social areas and fitness room.

This was an exciting project due to the original building occupancy type (repurposed), height ceiling requirements and the exceptional finish requirements.
