Construction FAQs

What is the construction schedule?

Below you will find the anticipated schedule. As is the case with any construction project, the schedule is subject to change, and we will provide updates as construction progresses.

Capture site, fence, sidewalk shed - COMPLETED

Lehman Hall will be closed and scaffolded; a security fence will seal off the construction site and an above ground walkway will be installed for pedestrian access across campus.

Abatement and demolition operation - COMPLETED  

Hazardous material remediation – also known as abatement ‐‐ will occur along with demolition of Lehman Hall; the building will be demolished from the top down, a noisy operation; noise and dust mitigation measures will be in place.

Excavation and foundations - COMPLETED

Preparing the site for construction entailing excavating and removing rock and creating the new
foundation for the building. This part of the operation will be noisy and noise and dust mitigation
efforts will be in place.

Rock excavation - COMPLETED

This operation involves drilling and splitting rock. This is the noisiest part of the construction
project and is expected to occur over the summer. Noise and dust mitigation efforts will be fully
in place.

Steel erection and concrete superstructure - December 2016 through April 2017

During this phase we will see the building rise first with a steel structure and then with concrete.

Exterior wall - April through August 2017

Installation of the exterior walls of the building including the façade.

Building watertight - September 2017

The point where the exterior wall is completed and the roof has been installed so that all work is
now confined to the interior of the building.

Interior finishes - May 2017 through April 2018

This phase focuses on fitting out the interior spaces; landscaping will also begin.

Temporary Certificate of Occupancy - Anticipated May 2018

The construction is substantially complete and ready for the installation of furniture and
equipment.

Furniture and equipment - May through August 2018

Installation of furniture and equipment to finalize the interior spaces, including the return of
Barnard’s book collection from offsite storage.

Beneficial Occupancy - August 2018

The building opens.

How can I receive information and updates on the construction?

We will be using several means to communicate with our neighbors including regular email updates, signage and our @MillieBuilds Twitter account. If you have questions or would like to receive the email updates, please send your questions, name and email address to newbuilding@barnard.edu.  We also are continuing to update this website with information, timelines and new renderings.

If you have urgent issues that need addressing once construction begins, please email constructionteam@barnard.edu during regular work hours, or for off hours, call Barnard Public Safety at 212/854-3362.

You can view Barnard's updated plan at Construction Plan.

What days and times will construction activities occur? 

Construction activities occur from 8 a.m. until 6:30 p.m. Monday through Friday and from 9 a.m. - 5:30 p.m. on select Saturdays.  No deliveries are permitted before 8 a.m. or after 10 p.m., except for large equipment that is required to by the City of New York to be delivered during the overnight hours.  

In addition, construction activities will cease during Barnard’s reading period and final exam weeks.

What kind of fencing will be built around the construction site? 

A site construction fence was installed in January 2016, sealing off the area currently occupied by Lehman Hall - from the Barnard Hall Annex to Altschul Hall and from Claremont Avenue to the Barnard lawn. 

The fence is 4-feet taller than NYC standards require and will surround the entire construction perimeter through the duration of the project. 

What are you doing to mitigate the noise?

While noise is a major concern for all construction projects, Barnard and Turner Construction is taking every practical measure to mitigate noise and remain within the standards allowed.  The College also hired a third party contractor to evaluate additional noise remediation effects and monitor noise, vibration, and dust during construction.

In addition to the site construction fence that is 4-feet taller than NYC standards, trucks used for construction are equipped with variable volume backup beepers to regulate truck noise during construction hours, and trucks, construction vehicles, and other equipment have sound mufflers. With the exception of concrete trucks which must run continuously so the concrete doesn't harden, trucks are not be permitted to idle along Claremont Avenue. Delivery trucks are staged away from the site and come to campus just in time for deliveries.

Barnard and Turner Construction also put together a schedule that has the most noise-intensive activities during times when they were less intrusive to the community, such as the excavation of rock that occurred during the summer of 2016. 

How will you handle traffic on Claremont Avenue during the construction?

Traffic concerns, especially as to how they impact pedestrians, are an important part of our construction plan. During days when there is work that impacts Claremont Avenue, flagmen are onsite to direct traffic and assist pedestrians in crossing Claremont Avenue.

The West 119th entrance to Barnard remains open for those who need to traverse from Claremont Avenue to Broadway.

What will be happening during the Spring 2017 semester?

Beginning in January and running through mid-April, the contractor will be erecting the steel on the portion of the building that rises above the foundation - also known as the superstructure. A crawler crane, located on the Claremont side of campus, is being used to build the superstructure. 

The steel erection operation will involve daily deliveries of steel to the site.  Delivery trucks will be queued on Riverside Drive and come to Claremont for just-in-time delivery. Before the steel structure reaches 75 feet in height, an outside hoist will be installed at the tower portion of the building on the Claremont Avenue side of the site.  This hoist will allow for staff and material deliveries to the individual floors.  The superstructure concrete operation will begin once the steel erection is three to four stories high.   

Once the steel is erected on each floor, concrete will be poured and the floor will be readied for the trades – carpentry, electrical, plumbing, etc. – which will begin setting embedded items and reinforcement on the deck. On the days of concrete pours there will be numerous concrete trucks coming to Claremont that will likely be concurrent with steel deliveries.  As a result, on these days there will be a higher level of construction truck traffic.

The new building will be built with 1,437 pieces of steel weighing more than 1,067 tons, or the equivalent of 164 African bush elephants. Approximately 5,027 cubic yards of concrete will be used in the foundations and superstructure - enough to build a five-foot side sidewalk that would run from Barnard College to the Brooklyn Bridge and back.
