Kaplan Construction is a Brookline general contractor and construction management firm. Its website names commercial, healthcare, multi-family, worship and institutional work. The company says it was founded by Ken and Cathy Kaplan in 1976, and a 2026 bostonrealestatetimes.com article describes it marking its 50th anniversary. Its Women Business Enterprise certification, number 20140203, is active on the Massachusetts Supplier Diversity Office registry, held by Kaplan Corporation d/b/a Kaplan Construction. In a 2023 Google review, the director of the Worcester Art Museum thanked Kaplan for its part in the museum's library relocation. In that same 2023 review, the director wrote that balancing the budget, the design and delivery had a lot to do with the project's success, and gave a shout out to Kaplan's PM, superintendent and onsite crew. A 2023 Google review from Sebastian Mariscal, principal of Sebastian Mariscal Studio and a developer of CALA in Somerville, said Kaplan played a key role in executing the design intent of that project, which re-used the building's structural system. A 2013 post on brookline-massachusetts.uscompanies.net called it a shady construction company doing illegal construction on weekends at 8am with no permit. That 2013 poster wrote that a site manager repeatedly lied about having a permit, and that in the end Boston inspectional services came through.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Kaplan Construction. Use it to sanity-check bids, then get the real number in writing.
Estimated range
$23,000 – $35,000
Typical remodeling project around $29,000
“Kaplan Construction is celebrating its 50th anniversary this year, marking five decades of steady expansion from its Brookline roots into a prominent general contractor and construction management firm serving projects across Massachusetts.”
“Kaplan Construction is the contractor and Guzman Prufer the architect of the project.”
“BOSTON – June 14, 2016 – Kaplan Construction, a WBE general contractor and construction management firm providing comprehensive building programs across Greater Boston, announced today that its COO, Jane Kaplan Peck, has been named an Outstanding Woman of Family Business by The Warren Group editorial board.”
“Shady construction company that does illegal construction on the weekends at 8am. No permit. Site manager repeatedly lied to my face about having a permit. Very creative lies and fabrications. In the end, Boston inspectional services came through (thank god) and hit them with the fine they deserved.”
A heartfelt thank you for Kaplan’s contribution to the success of our library relocation at the Worcester Art Museum, which doesn’t only require to move books. Balancing the budget, the design and delivery has a lot to do with that success, as does the willingness and aptitude to tackle complicated and intricate projects with little money and high expectations. Kaplan is a valued partner in WAM’s current and upcoming projects and I would like to give a special shout out to Kaplan’s PM, superintendent, and onsite crew for all of their hard work, including the systems our visitors cannot see. As we know, it takes a village to pull this off. -Matthias Waschek, Director of Worcester Art Museum
CALA in Somerville, Mass. is a successful case study of how the owner, architect, and contractor had to collaboratively work together in re-using the structural system of the building and ensuring its design intent stays cohesive throughout the space. Kaplan played a key role in respecting our vision, executing our design intent, and working with us as owners and architects of the project. CALA would not have been possible without Kaplan’s dedication, commitment, and enthusiasm to take on the challenge of this project. - Sebastian Mariscal, principal of Sebastian Mariscal Studio and co-owner/developer of CALA
