Castle Island Brewery South Boston
In late 2020, Kaplan Construction was hired to perform a 9,500 SF fit out at 10 Old Colony Avenue in South Boston to house a new craft brewery for Castle Island Brewing Company, the tenth largest brewery in Massachusetts in a ranking by total 2020 beer production, according to the Boston Business Journal.
Located within a turn-of-the-century high-bay manufacturing building, the brewery will feature a 4,000 SF main tasting room with seating for 220 people, a retail area, and a 1,900 SF private event space which can accommodate up to 140 people. A quarter of Castle Island’s new space will be reserved for the brewing operations, including a brewhouse and seven 10-barrel tanks. A large focal wall will be made from wood and metal and feature the Castle Island Brewing Company logo. Kaplan will cut out a section of the existing exterior wall and install a new overhead door to create a seamless indoor/outdoor experience and maximize natural light. In addition to removing a series of interior overhead doors, Kaplan will demolish existing walls at the front of the building to make room for tap room seating and new bathrooms. Two existing glass garage doors will remain to provide access to an outdoor patio for brewery patrons.
At the start of construction, Kaplan uncovered several unanticipated existing conditions in the century-old building despite multiple exploratory efforts performed by the design team and landlord. During concrete removal to accommodate the underground plumbing, it was discovered that the slab was three times as thick as the original exploratory work indicated. As such, the construction team had to work with the structural engineer on determining the best approach to address the cutting and infilling of the structural slab. Numerous underground obstructions, such as abandoned concrete structures, construction debris from past projects, and layers of old concrete slabs, were also encountered as the team excavated for plumbing to service the bar and brewing area. As demolition progressed, it was also revealed that the original bathroom plumbing had deteriorated significantly and required a full replacement.
The brewery and taproom are slated to open in the summer of 2021.
