CAMBRIDGE, MA — Gilbane Building Company, a builder of life sciences and commercial facilities in Massachusetts, has begun construction phase activities for the 224,000-square-foot build out and expansion project at the former Sears building at the Cambridgeside Galleria. This reimagined facility offers Class A lab and office space in the East Cambridge, Kendall neighborhood.

This complex expansion project involves the removal of the top floor and roof structure of the existing building and the addition of three new floors, all while structurally reinforcing the existing steel frame to accommodate the new building loads. A new fifth-floor balcony will overlook a garden with water features and pedestrian walkways in front of the mall below.

A two-story penthouse with architectural louver features to conceal all mechanical equipment will be added to the roof to reduce sound transmissions. Further adding to the complexity of this project is its highly congested location; all construction is taking place next to an operational shopping mall.

“We’re thrilled to be the builder of this cutting-edge project and be part of the team to deliver the vision for the new Cambridgeside,” said Mike O’Brien, Senior Vice President and Business Unit Leader for Gilbane in Massachusetts. “This new facility is raising the bar for the conversion of retail space to Class A mixed-use office and lab space, setting the stage for tomorrow’s innovations to become reality."

The expansion project is scheduled for completion by early 2023.
