181 Mercer Street

181 Mercer Street

Overview

181 Mercer Street , the new multi-use building expected to be completed in late 2021, 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.

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.

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, and fall 2017 or learn more about how we plan to minimize the effects of dust, noise, and traffic in the vicinity of the site.

 

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.
  • 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 such as jackhammers, saw-cutters, excavators, and burners. 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 at Washington Square Village Building 2, on West 3rd Street between Mercer Street and LaGuardia Place, is open to the public and the NYU community on Tuesdays from 3:00pm-5:00pm and by appointment. This space features renderings, schematics, and a model, and will remain open for the duration of construction. 

Project Timeline

  • Pre-construction work began in February 2016. The project is expected to be completed in late 2021.
  • 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 is scheduled to continue through winter 2018.
    • The 181 Mercer Street team has submitted an application to the NYC Office of Environmental Remediation (OER) to take part in the 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 is scheduled to continue through late 2018.
  • Core and Shell work includes the construction of the building structure and façade. Enclosure of the building is currently scheduled to be completed in winter 2020.
  • 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 completed in late 2021.

Current Project Update,

Dust monitoring report for week of April 9 through April 13.

Upcoming Work

  • NYU is scheduled to replace the damaged lane divider approaching the intersection of Houston Street and Mercer Street. This lane divider was installed per the direction of the MTA and the DOT to address pedestrian and bus safety concerns. The divider will limit traffic to bus stop pick-ups and drop-offs in the northern most lane of Houston Street (approaching the intersection of Mercer Street). This installation is scheduled to take place per DOT permits, the week of April 16, from 12:00am to 5:00am (during the hours when MTA does not run buses to this stop).

Ongoing Work

  • Foundation work continues on site and is scheduled to continue through late 2018.
    • Soil mixing continues onsite. This work involves mixing soil and grout to prepare and stabilize the area for drilling. Due to the nature of this work, a soil-concrete mixture remains in the vicinity of work at the end of each day's operation. This mixture cools and solidifies overnight.
    • Drilling and capping of the building's structural caissons continues onsite.
    • The pouring of concrete slab continues onsite intermittently. Concrete trucks are scheduled to enter the project site from the corner of Mercer and Bleecker Street, travel along the project site's drive lane within the project site on Mercer Street, and exit the construction site from Houston Street. Concrete pouring operations may also eventually involve concrete trucks driving down into the hole. 
      • Once the concrete arrives and is poured, concrete setting and finishing follows. Once concrete is poured, the team must wait for it to set completely before it can be finished as it is not possible to revisit concrete after it sets. Given that trucks can be delayed by weather or traffic, trucks are to arrive to the site by the early afternoon to avoid scenarios where work may go beyond our scheduled work hours. In cases, largely driven by traffic or weather conditions, work hours may be need to be extended to allow for the concrete to finish setting and subsequent finishing to take place, but again we are working to avoid this from occurring. The finishing work is performed with electric finishers that help mitigate noise.
    • Localized dewatering operations will take 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. Neighbors will be given advance notice of the need for overnight dewatering, which requires the use of mechanical equipment located near Houston Street within the construction site.
    • Trucks will enter and exit the site from either Mercer Street or Houston Street to haul the materials being excavated. All vehicles exiting the site are expected to use a wheel-washing station to help minimize the amount of dust that leaves the project site. 
  • Relocation of the western portion of the construction fence south of 100 Bleecker Street and east of 110 Bleecker Street is underway and is scheduled to continue through May. An updated site map can be viewed to see the area the fence relocation will enclose. Access to the Mercer Houston Dog Run entrance from the Silver Towers plaza will be maintained. Material deliveries are scheduled to arrive via the Silver Towers plaza and a boom truck is expected to be used during the fence relocation.
