Collaboration on Past Projects

JCK Underground’s founders and key staff possess a wealth of practical experience. Some of this experience was developed on projects such as Narragansett Bay Commission Combined Sewer Overflow Project, Massachusetts Water Resources Authority tunnel projects, and the Boston’s Central Artery (I-93)/ Third Harbor Tunnel Project, prior to the founding of JCK Underground. This shared experience on major projects led to the development of strong inter-personal relationships, mutual understanding, and trust in each other’s skills. This synergy and seamless collaboration translates to our ability to deliver quality results time and time again.
