Waltham, MA Callahan Construction Managers, a full-service construction management company that serves Greater New England and New York, celebrated the topping off of its 300 3rd Ave. project. The ceremony, held on October 6th, 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 3rd 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 3rd 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 s/f life sciences building will offer high-demand lab space to a growing life science cluster in town. 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 Rte. 128 corridor. Each floor will span 35,000 s/f 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 3rd Ave. is located 10 miles from Cambridge and Boston and is located off exit 27A on Rte. 128/I-95. Corporate neighbors include ThermoFisher, Sanofi, AstraZeneca, Shire, Deciphera, GSK, Alkermes, Immugen, PerkinElmer, Visterra and Exosome Dx.
