JC&A Celebrates 30 Years
JC&A has been a trusted partner of iRobot for over ten years now
“JC&A has been a trusted partner of iRobot for over ten years now. They have built over 500,000 SF of office, R&D, and manufacturing space, including our World HQ in Bedford, MA. These renovations often took place in fully occupied buildings that can be a nuisance to employees when not managed properly. JC&A is not only highly knowledgeable and resourceful, but they bring a sense of calm and predictability to our team through their constant communication that allows us at iRobot to focus on our essential work designing and building home robots.”
JC&A is simply the best
"JC&A is simply the best Construction Management firm I have hired in my 20+ years of developing life sciences real estate.
From pre-engagement through project completion, JC&A is collaborative, precise, motivated and transparent. Their ability to seamlessly integrate and manage third party design teams and consultants provides project schedule and budget continuity and instills confidence for me and my investors ensuring that every detail is covered.
I admire JC&A’s gender and cultural diversity hiring practices, clearly JC&A go above and beyond to reinforce D&I pillars within all aspects of their organization and the end result speaks for itself in unmatched quality, talent and reliability.”
