Central Artery Tunnel Project Leakage Investigation Boston

The Central Artery/Tunnel (CA/T) Project relocated Boston’s elevated Central Artery below ground.  Systemic water leakage at the tunnel roof to slurry wall intersection created a long-term corrosion threat to the roof girders and caused widespread ice buildup at the roof level in the winter.  SGH investigated the causes of leakage and assisted Modern Continental Construction (Modern) with locating and quantifying the leakage as part of their remediation efforts.
