Gilbane Building Co

Scope Of Work

Brooklyn’s historical landmark required renovations, a service extension addition and significant MEP upgrades to accommodate for the Museum’s complex climate control needs. Gilbane managed the phased construction services with a focus on maintaining the historical integrity of museum elements, including construction of a new floor over the severely deteriorated original glass-block floor of the Museum’s largest public space, Beaux-Arts Court on  the third floor and involved installation of new stainless steel framed glass planking and cementitious pre-cast terrazzo flooring.

Due to the Museum’s status as a historical landmark, the challenge was to maintain the historical nature of the floor while keeping it structurally sound. Moreover, in the Great Hall, located directly below the Court, the original coffering is now visible, as a result of removing the panels once installed under the vulnerable glass-block floor (in effect, the Hall’s ceiling) as a protective measure. From the Great Hall, the view upward to the original glass blocks is essentially as built, and the amount of light transmitted is not noticeably reduced.

The building addition achieved LEED Silver certification.

Other components of the project included:

Multiple gallery renovations

Interior basement renovation

Service extension addition

Mechanical system upgrades

Highly coordinated security plan
