TUNNELING PROJECTS

At DHC, we try our best to be the construction engineers that you can come to for any design on a construction site. So, when a contractor comes to us to design a jack and bore shoring system, we can help you make sure your casing and carrier pipe are installed safely. From start to finish, we’ve got you covered. Tunneling engineering normally starts with 2 excavation shoring designs. These 2 pits are typically called the jacking pit and the receiving pit but can go by a lot of names (launch pit, exit pit, jack and bore pit, etc.).
