Connecticut’s first Design-Build Project included replacement of existing superstructures combined with substructure rehabilitation. JTC was retained to support the contractor’s QC team to ensure that all CTDOT specifications were being followed and that the materials used in the project met the CTDOT requirements in both composition and performance. In addition, JTC monitored all construction operations involving the placement of structural materials to ensure that construction methods were in keeping with state regulations and best practices. The benefits JTC brought to the project included providing cost-savings to our client by scheduling three shifts per day, with limited overtime hours; continuously revising project timeline during planned and/or unplanned shutdowns; and expanding the services provided by our Quality Control technicians and inspectors, based on CTDOT Quality Assurance feedback.
JTC was part of the large Design/Build team led by The Middlesex Corporation, under the direction of the MassDOT, to replace the existing Kenneth Burns Bridge with a new steel deck arch bridge. Construction of the new bridge cost approximately $89M. The replacement bridge carries Route 9, known as Belmont Street in Worcester and Turnpike Road in Shrewsbury, over Lake Quinsigamond.
JTC scope of services included concrete, steel pile driving, and HMA paving inspection services, as well as testing services.

JTC provided project management services, along with resident engineering services, to ensure our client (the Town of Westerly, Rhode Island), a sound new development of Bay Street in the historic Watch Hill District. JTC acted as a liaison between our client and the contractor, confirming that the project adhered to RIDOT specifications and met all plans developed by the Engineer-of-Record. We managed concerns during construction between the residents of Bay Street, Watch Hill Police Department, Watch Hill Conservatory, Watch Hill Fire Department, Westerly Department of Public Works, and the Town Council, helping the project advance and remain on schedule.
JTC’s presence during the construction provided our client with reassurance, confidence, and support to successfully complete the Bay Street Streetscape Enhancements Project. We also provided materials testing on concrete, soils, and HMA.
