SPORTS ARENA

UBS Arena at Belmont Park, The Islanders’ 17,113-seat hockey arena is opened November 2021. It is the centerpiece of a $1.3-billion sports-and-entertainment development on the 43-acre parcel of state land adjacent to the Belmont racetrack. The new arena ends the Islanders’ decades-long search for a new home and brings the team back to Long Island full-time, which the team’s ownership has been seeking almost since the day the franchise departed Nassau Coliseum in 2015 for Brooklyn’s Barclays Center.

The retail center presents to visitors and residents a carefully curated collection of top brands through its seven levels and 100-plus shops, while The Restaurants bring together a variety of New York’s most celebrated cuisine.

A captivating interior space, 20 Hudson Yards features an 85-foot high central atrium defined on its west side by a custom-designed glass feature wall by James Carpenter. Clad in inverted “J”-shaped glass panels, the 300 foot long, 90 foot high wall provides spectacular views of the six-acre public space and offers a visual connection between interior and exterior. The north and south sides of 20 Hudson Yards feature triple-height circulation spaces with direct connections to the lobbies of adjacent 30 Hudson Yards and 10 Hudson Yards. Coupled with its entrances on 10th Avenue to the east, and access to the public spaces to the west, 20 Hudson Yards provides Hudson Yards with unmatched porosity from all sides.

In addition to its robust retail and hospitality program, 20 Hudson Yards’ technical innovations are also integral to the function of the over-rail development. Its eastern façade serves as the primary ventilation mechanism for the below rail yards, rendered as a series of meticulously detailed perforated steel panels. The building’s multi-level design negotiates the site’s change in grade from east to west, allowing for easy pedestrian access to Hudson Yards, while its roof accommodates a co-generation plant that supplies power to the entire development.

One Vanderbilt is a 93-story supertall skyscraper at the corner of 42nd Street and Vanderbilt Avenue in the Midtown Manhattan neighborhood of New York City. Designed by Kohn Pedersen Fox, the building was proposed by developer SL Green Realty as part of a planned Midtown East rezoning in the early 2010s. The skyscraper's roof is 1,301 feet (397 m) high and its spire is 1,401 feet (427 m) above ground, making it the city's fourth-tallest building after One World Trade Center, Central Park Tower, and 111 West 57th Street. 

One Vanderbilt's facade and design is intended to harmonize with Grand Central Terminal immediately to the east. The building's base contains a wedge-shaped void, and the tower tapers as it rises, with several "pavilions" and a pinnacle at the top. The facade is made mostly of glass panels, while the spandrels between stories are made of terracotta. The superstructure is made of steel and concrete, and the interior spaces are designed to be as high as 105 feet (32 m). The lobby has a bank branch and an entrance to the nearby railroad terminal and the associated subway station, while the second floor contains the Le Pavillon restaurant. Most of the building is devoted to office space, and the top stories contain an observation deck, Summit One Vanderbilt.

& CAMPUS CHILLED WATER AND HOT WATER DATA LOGGING 

This $4 billion Delta Air Lines Terminal C project is a critical part of the dramatic redevelopment effort at LaGuardia Airport (LGA). This massive endeavor will consolidate the airline’s operations into a new, 1.3-million-square-foot facility. The project entails the demolition of 600,000-square-feet of existing facilities. Once completed, Terminal C will consist of 37 flexibly sized aircraft gates distributed among four concourses connected by a centralized check-in lobby, security checkpoint, and baggage claim. Dual taxi lanes between the concourses will greatly improve airfield efficiency, resulting in reduced taxi time to and from the gate before take-off and after landing. The facility will offer larger gate areas and more seating, as well as doubling concession space over the existing facilities. There will also be direct access from LaGuardia’s East Parking Garage. 

Concourse G 

Delta Air Lines has opened the first concourse of its new Terminal C as part of the ongoing $8 billion transformation of Guardia into a unified 21st century airport. The seven new gates in the Delta Air Lines' Concourse G serve passengers traveling to Boston, Chicago and Washington DC.

Scope: All interior spaces and mechanical equipment 

The General Assembly is the central organ. This is where all 191 Member States can gather to discuss the pressing problems of our times, most of which involve many countries or continents and therefore require international cooperation. 

The General Assembly Hall is the largest room in the United Nations, with seating capacity for over 1,800 people. The design of the room was a collaborative effort by the team of 11 architects that designed Headquarters, and to emphasize the international character of the room it contains no gift from any Member State. 

Airpath performed multi-band acoustical analysis of all public and office spaces within the facility, graphing and comparing the baseline sound levels in an unoccupied mode and sound levels of during normal HVAC operation. The NC criteria for each interior space was listed and compared against the field results. 

Vibration level testing was measured was performed on all equipment over 3 HP. A tri-axial measurement was taken on the motors, fan housing, unit casing, and a building adjacent structural supports for the HVAC equipment. The goal is to identify bearing degradation and fan imbalance to determine if remediation is required or to identify equipment which should be monitored for rough operation as the units progresses through its life cycle.

Airpath initially identified many issues with the air handlers, fans, pneumatic controls, dampers, filters, duct connections, access doors, fire/smoke dampers, etc. Airpath offered suggestions for the equipment testing and MEP upgrades. To perform a detailed conditions assessment the process includes each air handler and fan, supply / return / and outsides air flow measurements, detailing condition of filters, recording fan and motor speeds, system component static pressure losses, damper operations, etc. This process is the first step required to determine the function and operation necessary to achieve design flow rates and temperature control. Part of this assessment was to determine if air flow is available for all air devices at the design rates. Duct traverses and capture hoods were used for this purpose. The total flow measured at the air devices should be similar to the actual fan capacity. If the air flow is not sufficient a determination is made to investigate causes of air leakage or blockages such as the position of the fire/smoke dampers and fire dampers in the duct work.

Existing HVAC Systems Performance Study and Retro-Commissioning for Con-Ed Solutions 

Airpath Engineering has participated in a multi-year HVAC energy efficiency initiative offer baseline testing services for HVAC equipment and terminals. This projects aim is to reduce energy usage through upgrades to more efficient HVAC equipment and identify areas of opportunity and re-balance most of the Hospital complex terminal devices. This effort includes VAMC Brooklyn, Manhattan, and St. Alban.

GCT / LIRR: Cavern and Tunnel Smoke Extraction Testing Flow Scenario Testing Study

Grand Central Madison is the largest passenger rail terminal built in the country since 1945 and one of the largest transportation infrastructure projects in the United States at present day. The three level o-level caverns support four platforms and eight tracks, and will deliver Long Island commuters direct access to Manhattan’s east side, this offers new commuting opportunities for reverse peak travelers and enhance New York’s regional connectivity.

The Grand Central Terminal Concourse connection to the LIRR cavern lower level escalators entrances travels a 5+ city blocks. Along this distance passengers have access to several LIRR/MTA entrances along Madison Avenue. To ensure proper ventilation and smoke extraction of the enormous passenger egress from the lowest LIRR cavern track tunnels to the concourse level exits towards the street level and Grand Central Terminal, scenario testing was performed. This effort is the largest smoke extraction flow measurement testing of its kind. Airpath, working in conjunction with the construction and design team performed flow pattern with unique intendent zone flow strategies being challenged in real world conditions.
