Arlington, MA – BW Kennedy & Co. recently celebrated the topping off of King Street Properties’ (KSP) 145,000sf speculative laboratory building at 828 Winter Street. The firm joined KSP; architect Perkins+Will; engineers Goldstein-Milano, Kelly Engineering, and Haley & Aldrich; the design-build MEP/FP team consisting of Environmental Systems, Inc., Nappa Electrical Contractors, North Shore Mechanical Contractors, and Legacy Fire Protection, as well as the subcontractor team to celebrate the milestone.

The three-story building will contain approximately 50,000sf per floor and will feature state-of-the-art mechanical, electrical, plumbing, and fire protection systems, designed to accommodate the varied needs of life sciences tenants. Also included in the project is a 158,000sf, four-level parking garage that was recently completed.

Topping off project team

The project is on schedule for completion in mid-2018 and will offer the Winter Street campus amenities such as two cafeteria options, outside seating in a central courtyard, conference facilities, structured parking, bicycle storage, and showers with changing facilities.


“According to Brian Kennedy, founder of BW Kennedy & Co., the topping off of this building results from many months of careful planning, and excellent work in the field. Built on a steep slope, the project provided a multitude of challenges, as well as the building’s location behind the 830 Winter Street property and parking area, which remains open throughout construction.”

The existing Winter Street campus serves as home to companies such as GSK, Immunogen, and Histogenics. The new building will help to continue to build the area as a thriving suburban hub for the life sciences community.

Tyson Reynoso, Senior Associate for King Street Properties, in charge of the project, said “BW Kennedy has again proven to be an excellent construction partner for King Street. The project team has successfully managed the complexities of building a ground-up laboratory building adjacent to an occupied laboratory building in a highly-active suburban office park. Construction of this project allows us to create a best-in-class suburban life science campus with urban amenities and scale. This further reinforces Waltham as a world-class life science destination.”
