Design-Build Services for Accessibility Upgrades at Eight Stations in the Five Boroughs of NYC

This project included the design and construction of Americans with Disabilities Act (ADA) improvements at eight (8) stations located in the five (5) boroughs of New York City, NY. These improvements achieved full vertical accessibility at the stations through the installation of a total of eighteen (18) elevators and other ADA-compliant upgrades.

Garg Consulting Services, Inc. provided electrical and lighting design services at the following stations:

• 7th Avenue: an underground station in Brooklyn on the IND Sixth Avenue Line serving the ‘F’ & ‘G’ trains. (1) two-stop traction and (2) two-stop hydraulic elevators will be installed.
• Lorimer Street: an underground station in Brooklyn on the BMT Canarsie Line serving the ‘L’ train. (1) two-stop traction and (2) two-stop hydraulic elevators will be installed.
• Metropolitan Avenue: an underground station in Brooklyn on the IND Crosstown Line serving the ‘G’ train. (1) two-stop traction and (2) two-stop hydraulic elevators were installed.
• Grand Street: an underground station in Brooklyn on the IND Canarsie Line serving the ‘L’ train. (2) two-stop traction elevators were installed.
• Beach 67th Street: a viaduct station in Queens on the IND Far Rockaway Line serving the ‘A’ train. (1) three-stop traction and (1) two-stop traction elevators were installed.
• Dyckman Street: an elevated station listed on the National Register of Historic Places located in Manhattan on the IRT Broadway Line serving the ‘1’ train. (1) two-stop traction elevator were installed.
• East 149th Street: an underground station in the Bronx on the IRT Pelham Line serving the ‘6’ train. (2) two-stop traction elevators were installed.
• New Dorp (SIR): an embankment station located in Staten Island serving Station Island Railway (SIR) trains. (2) two-stop traction elevators were installed.
