The keys to successful excavations and installation of buried pipes are planning and coordination. From site preparation to identifying haul-roads and commencing the drilling and blasting of rock and/or groundwater dewatering, a detailed sequence must be developed and followed.
The more control the general contractor maintains from the start, the less chance of encountering delays or safety hazards. With decades of self-performing experience on the majority of projects we construct, 3D is primed to be a valuable asset for earthworks and underground services.
We self-perform both small and large diameter pipe installations (as large as 84 inches in diameter) in all types of subsurface conditions, including in-rock underwater and on the side of a 500 foot high rock cliff. In that situation, we used a helicopter to place pipes on cast-in-place concrete pipe supports carved into the rock cliff before installation.
Time and time again, we’ve built solutions from the ground up and tackled the toughest projects.
