The life sciences market is rapidly changing – that much we know. While no one can predict the future, it is possible to build a cutting-edge laboratory and research facility that will adapt to the changing needs of scientists and researchers. That’s what is unfolding at 440 Bedford, a completely new approach to lab space in the coveted Lexington submarket.

440 Bedford Street is a new 6-story, 335,000 GSF Class AA speculative life science lab and office building being built by Callahan Construction. When finished, the building will include incubator lab space, graduator lab space, lab-ready spaces, a café, fitness center and other amenities. The building will also feature a retail and restaurant space on the first level and several outdoor amenities, along with a 6-level parking garage with parking for 575 vehicles. Put simply, this isn’t just a place to come work; it’s a destination for collaboration and an extension of one’s lifestyle.

Callahan’s pre-construction expertise was on full display during the early phases of the project, as the construction team discovered soil deficiencies that had the potential to cause substantial delays to the project schedule and significant costs to the budget if not resolved as early as possible. The preconstruction team as well as Callahan’s Site Division were able to find solutions to the problem that kept the project on schedule, saved money for the client, and strengthened trust between all parties on the project.

440 Bedford will feature numerous high-end touches, including modern interiors designed to inspire, flooded with natural light and plenty of amenities to keep scientists balanced. And with its location in the sought-after Lexington and Hartwell Avenue submarket, 440 Bedford offers ease of access to both the building and nature, not to mention proximity to other innovative companies and industries along with mass transit.

“Callahan is excited to once again leverage its experience with complex projects including laboratories and research facilities, along with our robust portfolio of pre-construction services, to build 440 Bedford,” said Steve Callahan Jr., Vice President – Business Development, Callahan Construction. “The team behind this project in Lexington knows how important it is to bring this cutting-edge research space to market, and we look forward to seeing it filled with the people and projects changing our world for the better.”

Waltham, MA – Callahan Construction Managers announced that Lincoln Property Company’s 300 Third Avenue project in Waltham has been awarded LEED Gold Certification from the U.S. Green Building Council (USGBC). Callahan provided construction management services at this 4-story, 139,000sf Class A facility, located in the Rt. 128 Tech Corridor.

Representatives of Callahan say that, in concert with DiMella Shaffer Architects, the firm was selected to oversee the construction of 300 Third Avenue thanks to its deep experience in laboratory construction as well as green building, and that when the project wrapped up in early 2022, it brought to market four stories of laboratory and office space with highly efficient mechanical, chemical storage and utility areas to service the most demanding laboratory operations.

From a sustainability standpoint, 300 Third Avenue offers a variety of green-focused features designed to support efficient building operations and sustainable lifestyle choices.
