Hi All,
I am the civil engineer on a project where we are installing below grade chilled water distribution pipe for a VA campus. A part of the pipe run needs to be routed below the foundation of an existing enclosed walkway (block walls concrete foundation and roof)the walkway is about 12' wide. I am considering using a directional drill method. Anyone out there spec a HDD under a building? There will be two pipes about 14" in diameter. My main concern is the casing pipe size and the depth below the foundation we would have to go.
Thanks!
