Structural|Underground Structures

Beyond THP’s experience with occupied underground structures, we have significant experience with underground utility and bulk storage structures. THP has designed over 5 miles of walk through utility tunnels constructed by both cut-and-cover and boring techniques. Our tunnel and waterproofing designs have been adopted as standards by a number of institutions. We are experienced with utility projects in urban street environments and we are sensitive to traffic maintenance in high volume vehicular and pedestrian areas.

Projects include:

  • Utility Tunnels
  • Electrical Vaults
  • Below-grade Water and Thermal Storage Tanks, up to 4 million gallons
  • Below-grade Fuel Storage Tanks
