ARK OF RETURN Permanent Memorial at the United Nations in Honor of the Victims of Slavery and the Transatlantic Slave Trade Rodney Leon won an international UNESCO design competition to erect a memorial to commemorate victims of the Atlantic slave trade. Here’s how the designer talks about the process: ”The Ark of Return” memorial is a sacred space that is designed to psychologically and spiritually transport visitors to a place where acknowledgement, education, reflection and healing can take place. The memorial’s exterior form is constructed in a fashion to reflect the image of a vessel or ship in acknowledgement of the millions of African people transported on slave ships to different parts of the world during the “Middle Passage.” Images of maps depicting the “Triangular Slave Trade” influenced the use of the triangle as a primary element in designing the memorial’s shape. The memorial is conceptually also organized in three parts and visitors are meant to pass through “The Ark of Return” to intimately experience three primary elements on the interior space. The first element is a three dimensional map inscribed on the interior of the memorial. This map highlights the African continent at its center and graphically depicts the global scale, complexity and impact of the triangular slave trade in “acknowledgement of the tragedy.” The second element is full-scale human figure lying horizontally in front of a wall inscribed with images of the interior of a slave ship. This is meant to communicate and educate visitors on the physical conditions endured by the millions of African people transported under extreme conditions during the middle passage. The visitors are provided the opportunity to seriously “consider the legacy” of slavery’s impact upon humanity. The third element is a triangular reflecting pool, which introduces water in a meditative, ritualistic and spiritual manner. Visitors are invited to pour libations or say a prayer in memory of the millions of souls that were lost “lest we forget” this monumental and historic tragedy. Altera Engineering were invited to advice the design team at the concept stage. The firm’s engineers were tasked with collaborating with the contractor for the General Assembly renovation in locating and bringing power and water to the sculpture of the Ark.

712 Broadway is an 8-story landmarked building located in NoHo (North of Houston) historic district. The iron frame, granite and terra-cotta building was constructed as a warehouse in 1893 for the Scholle Brothers. The commercial building designed by Alfred Zucker replaced an 1803 3-story Federal-style mansion, which the Scholle Brothers bought for $88,000 in 1890. NoHo saw its first development by the first decade of the 19th century when John Jacob Astor acquired a large tract of land between Great Jones Street and Art Street (now Astor Place). From 1820 to 1840 the area developed as a fashionable residential district lined with lavish Federal and Greek Revival style residences. New York University was founded in 1831 in nearby Washington Square. Altera Engineering provided MEP engineering design and approval services for a loft apartment, working closely with architects and owners to integrate state-of-the-art mechanical systems into the existing historic features of the apartments.

According to Landmarks Preservation Commission (LPC), 106 and 110 are two of three identical houses were built in 1867 by an Irish-American builder, James Mulry, at an estimated cost of $6,000. The three buildings were erected on the lots that Mr. Mulry leased from Hamilton Fish- the 16th Governor of New York State and the Secretary of State under Ulysses Grant. The buildings were designed in a late version of the Italianate style by D. & J. Jardine Architects. The segmental-arched doorways have stone cornico-slabs supported on vertical console brackets which, in turn, are carried on paneled pilasters. They are four stories high, above a basement, and all retain their stoops. They are all three surmounted by individual bracketed cornices which are aligned at the same level. The stone basement wall is carried up to sill height at the first floor with recessed stone panels under each window. Altera Engineering carried upgrades to power, water, sewer utility connections. Our engineers worked hand-in-hand with the interior architects to thoughtfully integrate central heating and cooling systems into the buildings.

Go Go 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.

Full MEP/FP design optimization, energy modeling Go PHILLIPSPORT CHURCH HOUSE A conversion of an 1823 Methodist church to a single family residence. Phillipsport United Methodist Church was one of the oldest buildings erected in village of Wurtsboro. Envisioned as a summer home, the owner/architect carefully inserted usable residential spaces into the existing 195-year old historic structure. Altera Engineering team worked closely with the designer to come up with a modern heating and cooling solution that can be seamlessly integrated into the building. Double height ceilings of the main sanctuary and 15-ft tall single pane float glass windows presented a challenge for heating and cooling that can meet the current energy code. The response was a high efficiency variable refrigerant volume system designed for both heating and cooling with displacement air supplies along the perimeter of the main sanctuary. The existing steeple was retrofitted to be used as a natural ventilation chimney.

Full MEP/FP design Go Go Full gut renovation of a landmarked townhouse located in the historic Tribeca North District. This 5-story, nineteen-foot-wide store and loft building was designed in 1883 by Thomas R. Jackson, an architect who worked extensively in the Tribeca area, for soap manufacturer James Pyle. The utilitarian Romanesque Revival design features red brick façade with rock-faced granite elements, corbelled brick cornice and cast-iron piers. Presently the building houses a Tokyo-style “Edo-mae” Sushi restaurant, which was awarded a single Michelin star in 2014. The upper floors of the building are being converted to a single family residence. Altera Engineering carried upgrades to power, water, sewer utility connections. Altera Engineering worked closely with architects to seal and insulate the original walls in order to minimize the occupants’ dependence on HVAC for comfort. Our engineers worked carefully integrated central heating and cooling systems above the ceilings and behind walls. The building is cooled and heated by a variable-refrigerant-volume system without the use of fossil fuels.
