With the wide variety of conventional installation and trenchless technologies currently available, an experienced and multi-disciplined design team is essential in meeting the complex requirements of an underground infrastructure project.
CDM’s experts in trenchless technology can help install or rehabilitate underground infrastructure while minimizing environmental impacts and community disruption. Our experienced geotechnical and infrastructure engineers are well qualified to plan, select, and design the trenchless technology solutions best suited to a particular condition or site. Our experience includes the largest application of cured-in-place pipe in the rehabilitation of a historic 108-inch brick sewer in Newark, New Jersey, named Project of the Year by Trenchless Technology in 2004. We have used pre-chlorinated pipe-bursting technology to restore a water distribution system with minimum disruption in the Everglades National Park. In Bangkok and Vietnam, we directed the tunnel jacking of several miles of 10-foot diameter sewers through soft clay.
