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, Fall 2018, Winter 2018, Spring 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. 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 
  • Foundation work began in fall 2017 and continued through early 2019. 
  • 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.
    • 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 a crawler and 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 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. 
    • 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 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. 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 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.
  • 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.

Current Project Update

June 14, 2019

Upcoming Work

  • At the request of the NYC Department of Environmental Protection (DEP) NYU will be replacing a portion of the water main on Bleecker Street between LaGuardia Place and Mercer Street in collaboration with the agency. The portion of the water main being replaced is located in the middle of Bleecker Street from the 4 Washington Square Village driveway continuing west through approximately the middle of the block. This work is scheduled to begin the week of June 17 and is expected to continue through early July, weather and site conditions permitting. Work will involve street trenching to remove and replace the existing watermain. Trenching will take place in sections and metal plates will be placed to cover the excavated area at the end of each work day.  To accommodate the required street trenching the vehicular and bike lanes will temporarily shift north and some parking spots on both the northern and south portions of the street will be temporarily inaccessible to accommodate the traffic lane shift and project and material staging. 
  • The crawler crane will be used to move large pieces of mechanical equipment into the sub-cellar of the building the week of June 17. Equipment will be delivered both during regular hours and for oversize/overweight loads, 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 8:00am. 

Ongoing Work

  • Core and shell work, which includes the erection of the building’s steel structure and façade has commenced. More information about the core and shell phase can be found on the 181 Mercer Street construction web page.
    • Concrete placement for the steel phase continues.
      • 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.
      • As typical for concrete operations during the cooler months, heaters may be required to run 24-hour before and 48-hours after concrete is poured. Per DOB Code, workers will manage the heaters onsite. The heaters are not expected to generate noise.    
  • Daily steel 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/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.
    • 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 or queue near the site until the start of regular work hours.
  • Utility work to set up the connection for permanent Con Edison service for the 181 Mercer Street building is underway, and is expected to continue intermittently through summer 2019. This work will be performed in conjunction with Con Edison and the NYC Department of Environmental Protection (DEP). Work will involve street trenching to run pipes from the site to existing mains in Bleecker Street near the intersection with Greene Street, and on Mercer Street near the intersection with Houston 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 the NYC Department of Buildings (DOB) and DOT permits for the work. Portions of the work performed by NYU are expected to take place during normal work hours.
    • To accommodate this work, a section of the construction fence, west of the gate on Bleecker Street and on Mercer Street near the intersection of Houston Street, will be removed and replaced with a temporary fence. The temporary fence will be shifted and reconfigured to accommodate the specific work being performed and to provide a pedestrian pathway around the work. Pedestrian traffic will be redirected across Bleecker and Mercer Streets intermittently during work hours to accommodate the street work. Flag-persons will be onsite to assist pedestrians across Bleecker and Mercer Streets. Following completion of this work the gate previously located on the northern portion of the site on Bleecker Street will be reassembled on the northwest corner of the project site on Bleecker Street and Greene Street. 
    • Trenching work will require the redirection of vehicular traffic on Bleecker Street near the intersection with Greene Street, and on Mercer Street near the intersection of Houston Street. Flag-persons will be onsite to direct traffic around the construction activity.
  • 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.
