Waltham, MA – A topping off ceremony was recently held for the 300 3rd Ave. project in Waltham.
The ceremony, held on Oct. 6, marked the placement of the final beam at the new life sciences building, which is scheduled for delivery in early 2022. Callahan Construction Managers, 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 the project. Attendees were invited to autograph the final steel beam that was adorned with project team logos before it was placed on the building.
After breaking ground in July 2020, the topping off marks the completion of the building’s vertical structure. The 140,000sf 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 facade, which faces the Route 128 corridor.
Each floor will span 35,000sf 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.
The new development is located 10 miles from Cambridge and Boston and is located off exit 27A on Route 128/I-95.
