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 reports from Fall 2016, Winter 2017, Spring 2017, Summer 2017, Fall 2017, Spring 2018, Summer 2018, Fall 2018, Winter 2018, Spring 2019, Summer 2019, Fall 2019, Winter 2019, 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. Each access point will be used for project operations. 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.

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.
  • Foundation work began in fall 2017 and continued through early 2019. 
  • Core and Shell work includes the construction of the building structure and façade. Steel work began in February 2019 and the installation of facade panels is scheduled to begin in spring 2020. Enclosure of the building is scheduled to be complete in spring 2021. 
    • Mobilization for the start of core and shell work took place in Janaury 2019.
    • The erection of the building’s steel structure requires the use of two tower cranes. The cranes will be used to move and assemble the steel and the façade as it arrives to the project site.
    • 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. 
    • 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 summer 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 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 for oversize/overweight loads, NYC Department of Transportation (DOT) permits may stipulate drop offs anytime outside normal work hours. 
      • Following deliveries that arrive outside regular work hours, the construction site will remain closed until the start of regular work hours at 8:00 am. 
      • DOT permitted deliveries, which are scheduled outside normal work hours, 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 or queue near the site until the start of regular work hours. 
    • Weather and site conditions may require crane operators to maneuver the cranes outside scheduled work days and hours according to DOB and DOT instructions. Forecasted weather may also require workers to perform post-storm assessments and clean ups outside scheduled work days and hours per the DOB.
  • The final fit-out phase includes interior construction of the building. 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.

Current Project Update

May 18, 2020

There will be no work scheduled onsite in observance of Memorial Day, on Monday, May 25. Work is scheduled to resume on Tuesday, May 26.

Upcoming Work

  • Installation of the facade of the building is scheduled to begin the week of May 18. This work is expected to continue through spring 2021, weather and site conditions permitting.

Ongoing Work

  • Core and shell work, which includes the erection of the building’s steel structure and façade continues. 
  • In order to accommodate construction operations on the upper floors of the building through the end of the core and shell phase, hoists continue to be constructed on the westside of the 181 Mercer Street building, weather and site conditions permitting. As the structure of the building is constructed, the hoists will also be extended to access the highest floors of the building’s towers.
  • Concrete placement for the steel phase is scheduled to continue intermittently through fall 2020. 
    • 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. It is essential for concrete to be finished properly to ensure the structural integrity of the building and it is not possible to revisit concrete after it sets. Given that concrete 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. 
  • Application of a fire-proofing material continues onsite. This work involves spraying a fireproofing material on the structure of the building. This operation is scheduled to take place within a tarped area on each floor of the building.
  • As part of the Co-Generation Power Plant upgrade, installation of utility piping continues to be installed across Bleecker Street near the intersection of Greene Street. Work is scheduled to continue intermittently through summer 2020, weather and site conditions permitting. Trenches are expected to remain open for the duration of the project, and will be covered and plated when not in use. 
  • Utility work to set up the connection for permanent Con Edison service for the 181 Mercer Street building is expected to continue intermittently through summer 2020. This work will be performed in conjunction with Con Edison. Remaining work is scheduled to take place largely below grade within manholes on Bleecker Street near the intersection of Mercer Street.
    • Please note, the details of DEP and Con Edison's work (i.e. work days, hours, and street access) will be dictated by the stipulations in City agency permits for the work. Portions of the work performed by NYU are expected to take place during normal work hours.
  • Daily steel, curtainwall facade, and equipment deliveries and pick ups are scheduled arrive to the site via tractor-trailer. Deliveries throughout the core and shell phase are scheduled to arrive both during regular work hours and for oversize and overweight loads, NYC Department of Transportation (DOT) permits may stipulate drop offs anytime outside normal work hours. Typically, the DOT will stipulate the truck's route to the site, as well as whether the truck will enter the site or queue near the site until the start of regular work hours. Following deliveries that arrive outside regular work hours, the construction site will remain closed until the start of regular work hours at 8:00 am.
