MassDOT Ted Williams Tunnel Inspection

Massachusetts

TranSystems was selected by MassDOT to provide tunnel inspection, reporting, load rating and evaluation services. The re-selection on this contract was primarily due to our success on previous assignments. The MassDOT tunnel inventory includes the Central Artery/Tunnels constructed as part of the Big Dig: the Thomas P. “Tip” O’Neill Jr. Tunnel (I-93 SB/NB Tunnel & Ramps), I-90 Connector Tunnels, and the Ted Williams Tunnel (TWT) as well as MassDOT’s legacy tunnels: the CANA, Sumner and Callahan Tunnels. The inspection effort included the structural, civil and functional system elements in accordance with TOMIE Manual, SNTI and 2018 MassDOT Tunnel Inspection Handbook. Deteriorated areas of the tunnels were identified using standard deficiency nomenclature with supporting sketches, tables and photos.
