Callahan Construction Managers

Callahan Construction Managers (Callahan), a full-service construction management company that serves Greater New England and New York, celebrated the topping off of its 300 3^rd Ave Project in Waltham, MA. The ceremony, held on October 6^th, marked the placement of the final beam at the new life sciences building, which is scheduled for delivery in early 2022. Callahan, along with developer Lincoln Property Company, architect DiMella Shaffer, Iron Workers Local 7, AHA Consulting Engineers, and elected officials and city councilors, gathered to commemorate the significant milestone in the ongoing progress of 300 3^rd Ave. Attendees were invited to autograph the final steel beam that was adorned with project team logos before it was placed on the building.

“We are thrilled to celebrate this pivotal phase in the construction of 300 3^rd Ave,” said Patrick Callahan, President of Callahan Construction Managers. “Callahan’s life sciences construction portfolio continues to grow at a rapid pace, and reaching this milestone is the result of hard, efficient work by both our team and our excellent project partners. We look forward to delivering this dynamic suburban lab development soon and continued collaboration with all of our partners.”

After breaking ground in July 2020, the topping off marks the completion of the building’s vertical structure. The 140,000-square-foot life sciences building will offer high-demand lab space to a growing life science cluster in Waltham.  All four stories of flexible and customizable office and laboratory space will feature an expansive glass curtain wall that will wrap the façade, which faces the Route 128 corridor. Each floor will span 35,000 feet and will have bright light and expansive views from each of the workspaces. The building’s poured concrete foundation and steel frame concrete deck will be juxtaposed by a glass entrance accented by a natural wood ceiling, along with custom lighting. Finally, the building will include five levels of parking, two above grade and three below, as well as a mechanical penthouse and roof deck.”

Waltham has emerged as one of Greater Boston’s most active life sciences clusters. 300 3^rd Avenue is located only 10 miles from Cambridge and Boston and is conveniently located off exit 27A on Route 128/I-95. Corporate neighbors include ThermoFisher, Sanofi, AstraZeneca, Shire, Deciphera, GSK, Alkermes, Immugen, PerkinElmer, Visterra and Exosome Dx.
