West 125th Street Streetscape Improvements Project
The West 125th Street Streetscape Improvements Project was vital in an area of Harlem known for its vibrant community and long entertainment and cultural heritage. The Project aimed to increase pedestrian access to the waterfront, improve intermodal connections, and implement streetscape improvements on the famed 125th Street corridor, extending between the Harlem Piers to the west and Old Broadway to the east. The work is a key step in transforming West Harlem into a world-class destination and premier regional business district long envisioned by city planners and community groups.
Construction activities included the following: Installation of street furniture, including benches, bicycle racks, and trash receptacles; adding planting beds and sidewalks; constructing cobblestone, asphalt and concrete roadways; improving water mains, sewers and drainage facilities; installing plaza, street, and architectural lighting; adding aesthetic treatments at a new transit plaza adjacent to 12th Avenue; and erecting transit shelters at bus stops.
UrbanNY provided comprehensive construction management and inspection services for this $20 million project. Pre-construction services included preparing cost estimates, performing constructability reviews, conducting community outreach and stakeholder coordination, and administering pre-bid conferences. During construction, UrbanNY conducted progress meetings, prepared and monitored CPM progress schedules, implemented and maintained a documentation control system, reviewed and processed change orders, conducted quality assurance and quality control inspections, processed contractor payment estimates, and coordinated construction activities with project stakeholders, including residents and businesses, the Metropolitan Transportation Authority (MTA), and adjacent Columbia University.

Metropolitan Transportation Authority (MTA)Read more: MTA PMC Elevator and Escalator Upgrades 58 DevicesProject Description
MTA Construction & Development undertook the replacement of thirty-seven (37) elevators and twenty-one (21) escalators in twenty-three (23) subway stations located in four different NYC Boroughs, including Manhattan, Queens, Brooklyn, and the Bronx. The project was procured under two separate design-build contracts (one for elevators and one for escalators) and was managed by a single project management consultant (NAIK-STV Joint Venture).
This 48 month fast-track program included pre-construction, construction, and closeout service. The SOW for the device replacements brought each piece of equipment to a state of good repair (SOGR) and included new operational and safety enhancements. All existing equipment and finishes were demolished and replaced in accordance with MTA C&D’s Project Requirements and Design Criteria, including brand-new architectural finishes. For elevators, two-way video communication with the headend station at the Railroad Command Center (RCC) were included in the 2020 NYS Building Code Requirements.
All other communication and life safety system requirements, such as CCTV, Fire Alarm, Access and Control, and Liftnet, were replaced with the latest equipment and software and upgraded. Electrical system upgrades were performed from the Elevator Machine Room (EMR) to the electrical distribution rooms. For escalators, devices were replaced and modified to accommodate increased escalator speeds of 120 feet per minute. This required structural modifications to the truss support beams to accommodate a longer truss length. Escalators were upgraded with “sleep mode” technology to extend the overall life expectancy of the devices. All other communication and life safety system requirements, such as CCTV, Fire Alarm, Fire Sprinkler, Access and Control, and Liftnet, were replaced and upgraded with the latest equipment and software.
Vertical Transportation Services Provided
As the provider of Vertical Transportation Inspection Services, UrbanNY delivered full-service inspection, audit, and commissioning support to the NAIK-STV Joint Venture for this program. UrbanNY’s Vertical Transportation Division oversaw the installation, inspection, testing, audit, and commissioning of all elevator and escalator devices. From the design phase through commissioning and turnover, UrbanNY helped ensure that all systems were installed in accordance with project requirements and applicable codes and were safe, reliable, and ready for public use. The team reviewed vertical transportation designs for code compliance, identified issues that may not meet minimum requirements, and worked with the project team to resolve them before and during construction. UrbanNY also supported ongoing coordination among MTA C&D, the NAIK-STV JV, contractors, and special inspectors to help maintain quality, schedule, and compliance throughout project delivery.
Unique Aspects of the Project
This $400M multi-borough Design-Build program involved replacing 37 elevators and 21 escalators across 23 active subway stations in Manhattan, Queens, Brooklyn, and the Bronx within an aggressive 48-month schedule. The work required maintaining full passenger operations while performing complex structural modifications, electrical upgrades, and life-safety system integrations in constrained station environments. Challenges included coordinating simultaneous construction across high-ridership locations, sequencing work to ensure ADA access and safety, and managing two separate Design-Build contracts under unified oversight. Advanced features such as two-way video communication to the Railroad Command Center, higher-speed escalators with truss modifications, and “sleep mode” technology added to the technical complexity, making this one of MTA C&D’s most demanding vertical transportation replacement programs.

Battery Park City Authority (BPCA)Read more: Construction Management Services for Tribeca Bridge PaintingThe Tribeca Bridge, which crosses the West Side Highway near Chambers Street in Manhattan, was repainted — the first repainting since the bridge’s construction in 1992. The bridge connects directly to Stuyvesant High School, one of the most elite public high schools in the country. The $2.3 million project was completed ahead of schedule and within budget, without safety incidents, claims, or change orders.
Urban provided construction management services for the Battery Park City Authority (BPCA). We monitored the work of up to three contractors and supervised a field inspection subconsultant. Project challenges included painting in winter weather conditions; maintaining safe access for Stuyvesant High School students; and maintaining traffic over the 11-lane West Side Highway. To expedite the project despite winter conditions, the contractor contained and heated the entire bridge. Traffic control involved night time alternating single and double lane closures to install and remove the containment platform.
In addition to construction management, Urban provided bridge safety inspection services, after a hole was discovered in a bridge beam. Our bridge inspectors provided BPCA a report and recommendations to repair the hole. We also worked closely with the contractor to respond to student and teacher concerns about paint fumes, hiring an environmental firm to verify that the air quality inside the school was safe.
