Built in 1954, the complex consists of 22 three- and six-story buildings containing 607 apartments housing 1,658 residents across a 21.75-acre site. The project included a complete renovation of the existing space including all finishes, fixtures, HVAC, fire alarm, plumbing, and lighting, and provided flexible, multi-purpose programming. Support spaces included accessible restrooms, a janitor’s closet, and an IT/server closet. Exterior work included replacement of the existing canopy, new doors with actuator and door bell, and new lighting. The program also included community gathering spaces with audio/visual capabilities, a computer lab, and a commercial kitchen. Mechanical systems included: • An all new high efficient all-electric multi-zone VRF system • Distributed ERV’s throughout the space • All new electrical distribution • All new domestic and sanitary plumbing

Home / Residential 347 WEST END AVENUE ARCHITECT . Lamb & Rich PROJECT SIZE . PROJECT COST . SCOPE . MEP engineering design Go 347 WEST END AVENUE This Eclectic Renaissance/Revival building was designed with a limestone façade and gabled tile roof by famed architects Lamb & Rich as part of an original row of 14 houses in 1891. The home’s first owner was Charles F. Rand who made his fortune in the mining industry in Cuba and Spain. In the 1950’s, the property was converted to nine apartments, and now the new owners are converting back to a single family residence. The scope of the conversion included an additional set back fifth floor, with an elevator overrun, roof bulkhead, and copper and glass skylight atop it. The current three-story-tall projecting rear yard addition will be demolished and replaced with a four-story-tall rear yard addition. A Juliette balcony, clad in copper, will jut out just into the canopy of a 130- to 140-year-old cherry tree. This is Altera Engineering's third project along the historic West End Avenue, 915 West End Avenue and 309 West 86th Street. The Altera Engineering team worked closely with the architect to thoughtfully integrate new infrastructure into the existing historic shell. Altera Engineering provided MEP engineering design and approval services for all mechanical, plumbing and electrical systems.

NYC Department of Housing Preservation & Development has announced the selection of the Norma, an 11-story, 100% affordable home ownership project designed by Leong Leong with Almat Urban and Bedford Stuyvesant Restoration Corporation. The Norma (named in honor of Norma Merrick Sklarek, the first African American woman to pass her license exam to officially become an architect in both New York and California) will give rise to 44 homeownership opportunities through a mix of 1- to 3-bedroom condo-style coops for low- to moderate-income households with a broad range of affordability. Under the plans, the Brownsville Multi Service Wellness and Health Center will operate a new urgent care facility on the ground floor, providing services for adult medicine, pediatrics, physical therapy, OB/GYN, mental health and dentistry among others. A community terrace on the second floor will create space for community building, resident organizing and activities. Additionally, the building is designed to comply with Passive House energy efficiency and sustainability standards with a fully electric mechanical heating and cooling systems. Green Roof, Stormwater Retention, and Mechanical Systems In order to reduce load on the CSO, gardens and green spaces adjacent to the Northern facade can use storm-water in a retention and irrigation effort. A 1,067 sf green roof above the eleventh floor penthouse will absorb heavy rains and provide an extra layer of insulation, which will increase the energy efficiency and lower carbon footprints. The pavement in the rear yard of the site will be permeable so that aquifers can be recharged. Proposed planters on the second floor and eleventh floor amenity spaces with small trees and foliage will provide shade and a nice visual touch, as well as storm-water retention in its own right. The team proposes the use of a high-performance, high-efficiency HVAC system. Initial research centers on the feasibility of a variable refrigerant flow unit (VRF) mini-split with a heat recovery ventilator (HRV) unit, to provide (at least part of) the mechanical heating and cooling for the building.

Designed by the prolific Upper West Side architect George F. Pelham for the developer Joseph H. Davis, this building was constructed in 1906 as a small multiple dwelling (flats) and once known as the Albea. Located on the north side of West 93rd Street ninety-eight feet east of Riverside Drive, this six-story building faced in red brick with ironspot headers and stone trim is seventy-five feet wide and dumbbell-shaped in plan. The facade is capped by a modillioned metal cornice. An original wrought-iron fire escape is located at the center of the facade. The owners retained Altera Engineering in their bid to renovate and reposition the building as an upmarket rental property steps away from the Riverside park. Engineering scope included gut renovation of all vacant apartment units and building systems upgrade. A new high efficiency condensing boiler plant was designed to replace an outdated (once coal-fired) steam system. To fully take advantage of the condensing boiler efficiencies, all new hydronic radiators were selected around low water temperatures. Variable speed pumps were selected for low flow, wide delta-t of the water to minimize motor horse power. Domestic water was upgraded with indirect water storage tanks fed by boilers via plate and frame heat exchangers. The Altera Engineering team had to work around existing occupied apartments to minimize disruption to tenants. Altera Engineering provided MEP engineering design and approval services for all mechanical, plumbing and electrical systems. Home / Multifamily 325 WEST 93RD STREET ARCHITECT .

The project involves the infill development of three city owned blocks into affordable rental housing as part of the East Tremont Cluster project. This initiative aims to create three new affordable multi-family rental buildings on currently vacant sites in the Bronx. East Tremont is a neighborhood in the western Bronx, New York City, known for its rich history, cultural diversity, and working-class roots. It is part of Community District 6 and is bordered by the Cross Bronx Expressway to the south, Bronx Park to the east, and Third Avenue to the west. Between the 1940s and 1970s, East Tremont underwent major demographic shifts. A turning point came with the construction of the Cross Bronx Expressway, initiated by urban planner Robert Moses in the late 1940s. The highway displaced thousands of residents and split neighborhoods apart, leading to economic decline and urban decay. Many middle-class families moved to the suburbs, and by the 1970s and 1980s, the area faced rising crime and poverty. Starting in the 1990s, New York City launched major affordable housing programs to revitalize East Tremont and surrounding Bronx neighborhoods. Key initiatives included: -NYC Housing Preservation and Development (HPD) projects, which renovated or built thousands of affordable units. -Nehemiah Housing Program, which helped construct new affordable homes. -Public-private partnerships with nonprofit developers to convert abandoned buildings into viable housing. -New affordable housing developments, including those funded by HPD’s Neighborhood Construction Program (NCP). -Infrastructure improvements, such as better transit options and street enhancements. -Small business growth, with more restaurants, shops, and markets opening to serve the growing population. -Green space restoration, with nearby Bronx Park and Crotona Park receiving upgrades. The three development sites are located at 907 East 175th Street, 1900 Marmion Avenue, and 706 Fairmount Place. The proposed developments will collectively produce approximately 64 affordable rental units and one superintendent’s unit, totaling around 53,515 square feet of residential floor area. Of the 63 affordable units, approximately 16 will be designated as Affordable Independent Residences for Seniors (AIRS). Additionally, 10% of the total residences will be reserved for formerly homeless families and individuals. The project is funded through HPD’s Neighborhood Construction Program (NCP), which provides financing for the construction of infill rental housing with up to 30 units affordable to low-moderate, and middle income households.
