Citnalta Construction Corp. was the general contractor on the Bowling Green Station, Lexington Avenue Line Elevators and ADA Upgrades project. The Bowling Green Station is a designated Key Station in the New York City Transit rapid transit system. The purpose of the project was to perform physical improvements to bring the station to compliance with the Americans and Disabilities Act Accessibilities Guidelines. The scope of work included: the installation of a new three-stop elevator from Bowling Green Park to the upper and lower mezzanines and a new two-stop elevator from the lower mezzanine to the southbound platform, a glass arch canopy over the main stair entrance, platform reconfiguration and reconstruction, a new control area and fare array configurations at the lower and upper mezzanines, a new graphics and signage, and miscellaneous architectural repairs.

Citnalta Construction Corp., in a joint venture, worked on the new three-level pedestrian transfer connector that linked the Jay Street Station (A/C/F Subway Lines, Independent Line) with the Lawrence Street Station R Station (Brooklyn-Manhattan Transit) in Brooklyn, New York. The connection formed a historical milestone because it was the first time in the New York City Transit system’s history that the Independent Line and the Brooklyn-Manhattan Transit Line connected.

The JV team built a 15,000-square-foot pedestrian transfer connector which connected the roof of the Lawrence Street Station with the eastern elevation of the Jay Street Station. To build the connector, the joint venture team excavated an entire city block in downtown Brooklyn and underpinned the existing buildings on both sides of the street. Schiavone-Citnalta, JV replaced the roadway with a sophisticated temporary decking system in order to maintain the normal flow of traffic on the street above (Willoughby Street). This complete station rehabilitation consisted of approximately 100 LF of new connector and passageway mezzanine built over the existing Lawrence Street Station platform and tracks. The project included two escalators, one elevator, and two stairways that connect to the Jay Street Station as well as new structural reframing of vents on the mezzanine level over Jay Street Station tracks and ADA elevators from the street to the platforms at both stations.

Citnalta Construction Corp. renovated and restored the historic 96th Street Station. Citnalta performed a significant amount of work adjacent to the tracks to construct a new control house above the street. Citnalta’s scope of work also included building a new control house on the street median through the track bed. To accommodate for this work, three blocks of street and sidewalks were reconfigured.

The project also included a landscaped plaza in front of the north entrance to the control house. The entire station, including electrical, architectural finishes, mechanical and plumbing were renovated and restored to new as part of the project

All seven stations received new rubbing board and tactile edges, along with new windscreens and stairs from street level to the mezzanine and up to the platform. Additionally, the joint venture team renovated key structural and architectural components of the work at each above-ground subway station, including structural steel repairs to the line structure between and adjacent to all stations. The Bay Parkway Station was completely renovated including its historic plaster and terracotta tile façade.

The work also included selective demolition of the façade and plaster. The historical restorations included replacing the stucco plaster and the terracotta copper and clay tile roofs of the 100-year administrative building. The station remained fully operational throughout the construction; to achieve this, Citnalta performed staged demolition and erected a sidewalk bridge and safe zone by creating a tunnel for passengers during the construction

Citnalta Construction Corp. was the General Contractor for the Repair of The Brick Arch at the 168th Street and 181st Street Stations in New York, New York.

This project involved several improvements such as: the removal of ceiling bricks and the replacement of the bricks with Glass Fiber Reinforced Polymer (GFRP) panels, the replacement of all medallions at both stations in the arch areas, the installation of new granite flooring in the 168th Street Station platforms and the upper mezzanine, and the installation of a new armature with gutter and light fixtures in both stations.

Citnalta also self-performed the removal of the ceiling bricks and the concrete platform floor in the 168th Street Station.

Preserving the historical elements in both stations was also a major component in the performance of the work. Ceiling bricks from the arch structure were replaced with new GFRC panels to recreate the historic brick arch ceiling. Other historic elements, such as terracotta ceiling medallions were replaced and replicated in GFRP. Also, new ceramic tile and mosaics were installed at the Northbound gallery wall and columns at the 168th Street Station

This project involved component repairs on three stations in Manhattan: City Hall Station, Rector Street Station, and Whitehall Street Station, and two stations in Brooklyn: Court Street Station and Jay Street Metrotech Station. All the stations are on the R subway line on both sides of the Montague Tube, which was being completely rehabilitated and upgraded after damages caused by Hurricane Sandy (under a separate contract).

The component work involved structural platform edge replacements with new polyurethane rubbing boards, tactile warning strip panels and raised ADA boarding areas, approximately forty thousand square feet of concrete topping replacement, structural steel repairs at various locations, light fixture retro-fit upgrades and new fixture installations, new wall tile installation, rehabilitation of various street stairways including new cast aluminum treads and ADA compliant hand railings, drainage upgrades and additions, crack and spall repairs, lead abatement and painting, and photoluminescent (glow-in-the-dark) strip egress guide installations.

The Hicksville Station is the third busiest station operated by the Long Island Railroad Company (“LIRR”), and it is a key transfer point to the Port Jefferson and Ronkonkoma branches.

The improvements to the station included the redesign of the 2,000 LF precast/concrete overlay platform to a cast-in-place platform replacement to decrease project durations and increase productivity. The scope also involved the installation of radiant heat, substructure rehabilitation, upgraded electrical service, lead and asbestos abatement, installation of two new elevators, two escalators, aluminum stairs, platform level waiting rooms, and a translucent canopy roof system with drainage, lighting, and signage. Additionally, the project included the installation of a 2,000 LF drilled caisson precast H beam and lagging retaining wall, and the removal and replacement of 1,600 LF of platform canopy roof system with drainage, lighting, and signage. Through the work that Citnalta performed, the platform was brought to a state of good repair, is ADA compliant, and enhanced passenger and employee safety.

The North Track Siding received a new retaining wall, duct bank systems, and pre-wired signal hut and case. The scope of work also involved the removal of the existing signal bridge and foundation.
