Every year workers are severely injured or die in unsupported excavation collapses. Collapses that could have easily been prevented with the use of a shoring system. OSHA outlines specific requirements for trench safety and excavation support, and many times that requires the knowledge and involvement of a professional engineer. DHC specializes in the design and certification of temporary earth retention systems. While the majority of our work focuses on “site specific” engineered plans for particular locations on projects, we are also involved in the design of the trench safety equipment with the manufacturers of trench shields, hydraulic trench jacks, and slide rail system. We are a proud member of the North American Excavation Shoring Association (NAXSA), with DHC president Jasper Calcara acting as the chairperson for the engineering committee.

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.).
