Subterranean Solutions provides field services ranging from GPS control densifications and traverses, to site development and layout.
We provide control transfers from the surface to the tunnel elevation at the shaft locations and can provide shaft as-built documentation for positioning, verticality and volume reporting to assist in concrete and backfill quantities.
Using the transferred control from the surface, we will establish an underground control network. This methodology assures accuracies are maintained throughout the entire length of each project. Specified tolerances dictate the length and frequency of tunnel control extension campaigns.
