181 Mercer Street

181 Mercer Street


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, Fall 2017, Winter 2018, and Spring 2018 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.
  • Intermittent loading and unloading of deliveries and equipment may temporarily impact vehicular and pedestrian traffic. Flagmen 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 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 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 on Mondays from 3:00pm-5:00pm and by appointment.

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.
    • As part of the foundations phase, 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.    
  • 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.

Dust monitoring report for week of September 10 through September 14.    

Ongoing Work

  • Foundation work continues on site and is scheduled to continue through late 2018.
    • Capping of the building's structural caissons continues onsite.
    • The pouring of concrete slab and walls continues onsite intermittently. 
      • 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.
  • Work to address pre-existing street settlement issues within the eastern side of the construction site along Mercer Street is underway and scheduled to continue through early-fall 2018. Work will involve excavation of the existing surface within the construction site, compaction of the remediated area, and conclude with back-filling, and concrete pouring. This work is scheduled to take place within the site, from the corner of Mercer and Bleecker Street to the construction gate on Mercer Street north of Houston Street.
