Development in the Riverside-West End Historic District Extension I went through several phases in the years between the 1880s and 1930s. The earliest phase between roughly 1885 and 1900 saw the construction of speculatively built row houses and flats for the middle and upper classes. By the turn of the century, developers began to focus on constructing larger apartment buildings as increasing construction costs ended row house construction, and the newly opened IRT on Broadway made the Upper West Side more accessible to the city’s expanding population. Legislation such as the 1901 Tenement House Act, the 1916 zoning ordinance, and the 1929 Multiple Dwelling Law contributed to the transformation in the scale of the streetscapes of West End Avenue, Riverside Drive, and West 79th and West 86th Streets where row houses and smaller buildings were replaced by newer, larger buildings.[1] 309-311 West 86th Street was commissioned as a hotel in 1912 by Weymer Hinckley Waitt- a railroad engineer turned hotelier, whose company later built the Weylin Hotel on Madison Avenue. The 12-story 40,000 square foot building was designed by Schwartz Gross and completed in October of 1914 at a cost of $250,000. Originally known as Hotel Wayne until 1953 when it was converted into the Waldorf Nursing Home. In 1962 it became a residence club for senior citizens. Following interior alterations in 1979 the building was reconverted into apartments and became a co-op known as Stetson House. In 1984 John F Kennedy Jr. and Robert Littell moved in together into a 2-bedroom sublet at 309 West 86th Street. 309 West 86th Street is one of several Altera Engineering projects along the historic West End Avenue. Altera Engineering was retained to provide engineering design and consulting services for the owners of the penthouse apartment. The project involved a full floor gut renovation.

About 4,500 SF PROJECT COST . $3 million SCOPE . full MEP design and construction administration services Go 138 NORTH 1ST STREET, BROOKLYN, NY A ground up construction of a luxury single family home in Williamsburg neighborhood of Brooklyn. An inaugural project for a nascent developer required careful attention to detail. Altera Engineering worked hand in hand with the architect and developer to craft solutions that worked with the owner’s vision for the building. Altera Engineering efficiently and successfully secured utility connection approvals and assisted the client in resolving filing and approval issues. Altera Engineering consulted the owner on high performance building strategies, such as passive heating and cooling, insulation and envelope air-tightness, intelligent lighting controls, highly efficient domestic water heating and continuous ventilation with energy recovery. With the exception of domestic water heating, the building does not use natural gas or any other fuel for heating, and is cooled and heated with a variable-refrigerant flow system. Highly insulated envelope, and not relying on gas for heating are expected to save 20 metric tons of Carbon Dioxide emissions on an annual basis.

915 West End Avenue is a 120,000 SF 15-story multifamily building commissioned by a prolific upper west side builder Joseph Paterno (whose initials were inscribed above the entrance), designed by Rosario Candela and completed in 1922 at a cost of approximately $625,000. The building was designed in Renaissance Revival style, and is laid out as two wings around a central core with outer court. Boiler room, laundry facility, oil tank, and incoming services are located in the basement. Lobby and 94 apartments are located on floors 1 through 15. In 2015 the building was included into Riverside-West End Historic District Extension II, and is subject to certain Landmarks restrictions. Following the $ 85.5 million acquisition by a group of investors, Altera Engineering was retained to evaluate the existing heating, plumbing, gas and power distribution systems. Our engineers worked closely with the owner’s architects and marketing team to identify and carry out short payback upgrades to support the investors’ conversion and repositioning program to the ‘best-in-class’ multifamily rental. 915 West End Avenue is one of several Altera Engineering projects along the historic West End Avenue 347 West End and 309 West 86th Street.

Due to the low budget for the MEP systems, Altera engineers were challenged with finding efficient solutions using older technologies. The client opted to save money on the cooling system by selecting packaged through wall air conditioning units (PTACs). As a result, the only opportunity to improve efficiency lay in the building’s heating system. High efficiency condensing boilers were specified. To achieve operational efficiencies, the team implemented thoughtful zoning of the hydronic distribution based on façade exposures, allowing water temperatures and hot water supply to adjust in real time according to demand. All apartments were equipped with smart thermostats wired into an addressable network, enabling the operator to monitor, control, override, and track energy use at a granular level.

Go Go 2 Bushwick Avenue is a 14,000 SF ground up retail and office building being constructed on a site of a former gas station and auto repair shop. The corner site sits in a prime location of a rapidly gentrifying creative hipster mecca. The developers were interested in attracting local nascent businesses by creating affordable flexible spaces. Before commencing with design, Altera Engineering engaged with the owners and architects in the programming phase, to understand how the property will be positioned in the market and who will be the target tenants. The early-phase involvement informed the selection of suitable MEP systems. With careful system selection and sizing, the design team was able to strike a balance between considerations for the first cost, ease-of-use, flexibility and “curb” appeal to prospective tenants.

Home / Residential 535 PARK AVENUE: MULTIPLE APARTMENTS ARCHITECT . PROJECT SIZE . 86,000 SF PROJECT COST . SCOPE . MEP engineering design Go 535 PARK AVENUE: MULTIPLE APARTMENTS 535 Park Avenue is located just ½ blocks south of the Upper East Side Historic District. The development of the general area began around 1807 when the City established Hamilton Square as a boon to real estate developers on the tacks of land north of 59th street. Northward expansion of the city was first fueled by growing influx of Irish and German immigrants following the Irish potato famine, and the Revolution of 1848. The completion of Central park in 1858 and construction of elevated railroads on the north-south avenues in the late 1870’s further drove the speculative development in this part of the city. According to History of Real Estate, between 1868 and 1873, the value of property above 59th Street rose over 200 percent. In 1910 the New York Central Railroad decided to build a new Grand Central Terminal and to place the lines running along Fourth Avenue entirely below ground. Thus when the tracks were completely covered over. The name, Park Avenue came into general use replacing Fourth Avenue, and landscaped malls were placed down the middle of the road in the area which previously had been left partially open for ventilation above the railroad tracks. Park Avenue quickly became lined with the same type of luxury apartment buildings which were rising on Fifth Avenue. Once associated with the poor and working class, after the World War I apartment living began to become fashionable for wealthy New Yorkers. In 1909 A consortium of lawyers, bankers and a painter commissioned Herbert Lucas to design a 15-story 35-unit coop building on the southeast corner lot of Park Avenue and 61st Street. Named Number 535 Park Avenue the building was designed of steel frame structure with terra cotta and brick façade adorned with splayed lintels and half-oval balconies. When completed at a cost of approximately $550,000, the building comprised 86,000 square feet and provided hotel-like amenities, such as furnished lobby, uniformed doormen, and elevator operators. Original mechanical systems included central ConEdison steam. Original apartments did not have central air conditioning or cooling, and most of the units had outdated electrical service. Altera Engineering provided MEP engineering design and approval services to several apartments in this building, working closely with architects and owners to integrate state-of-the-art mechanical systems into the existing historic features of the apartments.

30 West is a proposed new 100% affordable multifamily development. The site of the proposed Project is currently a municipal parking lot for community use, and the Village of Haverstraw has committed to enter into a 99-year ground lease with Westhab to facilitate the development. The Project will have a total of 79 units of affordable housing which will be priced at levels that are affordable to very low- and low-income tenants. It includes two levels of parking that will serve both building residents and the surrounding community. The Project is being developed through a public-private partnership with the Village of Haverstraw to address the growing challenge of high housing cost in Haverstraw and throughout Rockland County. 30 West will be a 100% affordable housing development with a focus on serving the hardest to reach members of the community. 23 of the units will be reserved for households at or below 30% of Rockland County’s Area Median Income (AMI), and between 15 and 20 of the 30% AMI units will be reserved as supportive housing units to serve formerly homeless individuals and families, individuals with mental health, and/or individuals with substance use disorders, among others. Services for the supportive units will be provided by Westhab, Inc, and referrals will be provided by Rockland County Continuum of Care, through the Department of Social Services and local community organizations. The remaining units in the Project will be designated for tenants earning up to 60% AMI. Residential amenities will include an on-site office for supportive services, a laundry room, a community room for tenant use, and an indoor/outdoor rooftop lounge overlooking the Hudson River and surrounding mountains. Through Westhab’s unique partnership with Cisco, the project will receive free hi-tech security and Wi-Fi equipment, lowering the cost of construction and providing free high-speed Wi-Fi to all residents. At the time of application, the Village did not have zoning regulations that would support the project. Working with the Village, we helped to draft a new zoning district that can be used for 30 West and for other affordable housing projects in the Village.
