181 Mercer Street

Overview

181 Mercer Street , the new multi-use building expected to be substantially complete in late 2021 and open in fall 2022, will house much-needed new classrooms, performing arts education and training spaces, a modern athletic facility, student and faculty housing, and approximately 7,500 square feet of space for a public atrium and community uses. This project also features a number of open space enhancements.

NYU is committed to minimizing the effects of dust, noise, and traffic in the vicinity of the construction site and has developed a plan with Turner Construction Company (NYU’s construction manager for the project) to implement NYU’s Restrictive Declaration commitments for construction mitigation. With the approval of the Department of City Planning, Henningson, Durham & Richardson Architecture and Engineering, P.C. (HDR) has been retained as the independent third party monitor to oversee NYU’s mitigation efforts. Read HDR's report from Fall 2016, Winter 2017, Spring 2017, Summer 2017, Fall 2017, Spring 2018, Summer 2018, and Fall 2018 or learn more about how we plan to minimize the effects of dust, noise, and traffic in the vicinity of the site.

 

Work Hours

  • Monday - Friday, 8:00 am - 4:30 pm
  • Workers may arrive onsite as early as 7:00 am.
  • Neighbors will be given advance notice of any changes to the work schedule.

Scope of Work

  • Decommissioning of the Coles building began in February 2016 and project site mobilization and demolition of the Coles building commenced in October 2016.
  • As per the NYC Department of Transportation and Department of Buildings, a sound attenuating construction fence was installed around the perimeter of the 181 Mercer Street site. To learn more see a site map or visit our About the Project Site FAQ page.
  • Intermittent loading and unloading of deliveries and equipment may temporarily impact vehicular and pedestrian traffic. Flag-people are scheduled to be onsite to guide vehicular and pedestrian traffic around the perimeter of the project site during the receipt of deliveries.
  • Periodic material deliveries and staging, dumpster and asbestos disposal truck placement, crane use, etc, will be located within the fenced in perimeter of the project site.
  • Periodic asbestos abatement will require the use of a specialized disposal container.
  • Salvageable items not dispersed to departments across the University were made available to local public schools and nonprofit organizations.
  • As with any active construction site, dust may be generated in the area immediately surrounding the work and noise and odors may be generated by hand tools and mechanical equipment that will be used to cut, bolt, weld and fasten steel. Learn more about how we plan to minimize the effects of dust, noise, and traffic in the vicinity of the site.
  • The 181 Mercer Street Open House Space, located in the NYU Gould Welcome Center at 50 West 4th Street, between LaGuardia Place and Mercer Street, is open to the public and the NYU community the first Wednesday of each month from 3:00pm-5:00pm and by appointment.

Project Timeline

  • Pre-construction work began in February 2016. The project is expected to be substantially complete in late 2021 and the building is scheduled to open in fall 2022.
  • Project site mobilization and demolition of the Coles building commenced in October 2016 and continued through February 2017.
  • Excavation, which includes the removal of the existing foundation, rock, and soil, began in May 2017 and continued through winter 2018.
    • The 181 Mercer Street team took part in the NYC Office of Environmental Remediation's (OER) New York City Voluntary Cleanup Program (VCP). Projects that are part of this program employ high quality cleanups that meet State standards. This program ensures that all vacant land with light to moderate levels of contamination—known as "brownfields"—can be cleaned up and redeveloped in a manner that protects public health and the environment.
    • More information about this program can be found at the OER website, which includes a Fact Sheet about the project’s participation in the program. 
  • Foundation work began in fall 2017 and continued through early 2019.
    • As part of the foundations phase, localized dewatering operations took place onsite, as determined by site conditions. Dewatering uses pumps to remove water that infiltrates holes dug during the foundations operation and ensures that water is discharged in accordance with the project's Restrictive Declaration, NYS Department of Environmental Conservation regulations, and NYC Department of Environmental Protection regulations. Site conditions and instances such as heavy rain may require overnight dewatering.   
  • Core and Shell work includes the construction of the building structure and façade. This work is scheduled to begin in February 2019, and continue for 18-months. Enclosure of the building is scheduled to be completed in winter 2020.
    • As foundations are being completed onsite, mobilization for the start of core and shell work is scheduled to begin the week of January 14. 
    • The erection of the building’s steel structure will require the use of a crawler and two tower cranes during the first phase of work.
    • The crawler crane will move around the project site while the tower cranes’ locations will be fixed on the eastern site periphery along Mercer Street. The tower cranes need to be able to reach each corner of the building to load and place steel. The cranes will be used to move and assemble the steel and the façade as it arrives to the project site.
    • Initially two tower cranes will be on site, but a third tower crane will be added as the steel structure begins to rise. All cranes will be used in accordance with the safety protocols proscribed by the manufacturer and the NYC Department of Buildings (DOB).
    • As the Core and Shell phase progresses, additional hydraulic mobile cranes may be on site from time to time for crane assembly as needed, resulting in temporary site changes. Potential temporary site changes may be expected in Spring 2019, Summer/Fall 2019, and Fall 2020. Neighbors will be given advance notice of site changes.
    • In addition to the use of cranes to move and assemble the steel and facade as it arrives to the site, hand tools and mechanical equipment will be used to cut, bolt, weld and fasten steel. As with any active construction site, noise and odors may be generated in the area immediately surrounding the work. 
    • Daily steel and equipment deliveries are scheduled to begin the week of January 14 and will arrive to the site via tractor-trailer.
      • Deliveries throughout the core and shell phase are scheduled to arrive both during regular work hours and per the NYC Department of Transportation (DOT) as early as 4:00 am to enable oversize/overweight loads to enter the City before 6:00 am. Following early morning deliveries, the construction site will remain closed until the start of regular work hours at 8:00 am.
      • Early morning DOT permitted deliveries are expected to arrive to the site daily. Typically, the DOT will stipulate the truck's route to the site, as well as whether the truck will enter the site to drop off the load before regular work hours or queue near the site until the start of regular work hours. 
    • Site Mobilization/Temporary Project Site Changes
    • Temporary changes will be made to the project site the week of Janaury 14 to accommodate a hydraulic mobile crane that will be used to assemble the crawler and tower cranes. 
    • The temporary hydraulic crane will be located on the eastern side of the construction site along Mercer Street midway between Bleecker Street and Houston Street.
    • The temporary hydraulic crane is expected to be onsite for the duration of the operation from the week of January 21, through February, weather and site conditions permitting. The schedule may also be impacted by NYC Department of Buildings inspections. 
    • Per the DOB and DOT, to safely operate the temporary hydraulic crane and ensure the safe travel of vehicles and pedestrians around the project site, additional space will be needed on the eastern periphery of the construction site, along Mercer Street.
    • This space will be accommodated by temporarily extending a portion of the construction fence (see site map) into the existing southbound vehicular traffic lane on Mercer Street.
    • This temporary extension will require the suspension of parking on this portion of the eastern side of Mercer Street, which will become the temporary vehicular traffic lane. The eastern sidewalk of Mercer Street between Bleecker and Houston Streets will remain open for pedestrian traffic. Flag-people will be onsite to direct pedestrian and vehicular traffic and "No Parking" signs will be affixed on Mercer Street starting the week of January 14.
    • The delivery and safe assembly of oversize crane equipment will require three days of intermittent street closures, scheduled for Monday, January 21, Tuesday, January 22, and Wednesday, January 23, scheduled between the hours of 10:00am and 2:00pm, on Mercer Street between Bleecker Street and Houston Street. The intermittent closures are expected to take approximately 30 minutes to 1-hour during the three days. Additional intermittent street closures may be required and advanced notice of the schedule will be provided. Emergency vehicles will be allowed access onto Mercer Street during this time. This work is weather and site conditions permitting. In the case of inclement weather, mobilization operations will be rescheduled for the next possible work day.
    • Following the delivery and assembly of the hydraulic crane, the crawler crane is scheduled for delivery and assembly the week of January 21. The two tower cranes that will be used during the Core and Shell phase are scheduled for delivery and assembly using the hydraulic and crawler crane the week of January 28. 
    • Additional changes around the project site will include the removal of 40 feet of parking both on the north and south side of Bleecker Street (approximately 2 parking spots), just off the eastern corner of Mercer Street. This space will be essential to enable trucks delivering steel and the facade to maneuver into and out of the construction site as well as for vehicular and pedestrian safety.
    • Delivery of some steel is scheduled to take place in early February before the tower crane assembly begins.  
      • DOT will dictate the hours of the deliveries for the overweight loads of the tractor trailers delivering materials to the site. Typically, DOT stipulates drop off's and pick up of oversize loads to be scheduled to take place as early as 4:00am to enable delivery trucks to leave the City before 6:00am. Following an early morning equipment drop off or pick up, the construction site will remain closed until the start of normal work hours at 8:00 am.
  • During the final fit-out phase, the building is enclosed and interior construction is underway. The landscaping of the Greene Street Walk will also occur during this phase. The project is scheduled to be substantially complete in late 2021 and the building is scheduled to open in fall 2022.
