A natural gas client was building two 5-million-gallon steel tanks to store freshwater for its hydraulic fracking process. They also needed to monitor tanks for movement during a hydrostatic test of the structures. The project’s major challenge was scheduling; a survey crew needed to be on call around the clock for the duration of emptying and filling the freshwater tanks.

RETTEW’s survey team placed almost 350 points on the floor and exterior walls of the tanks, and tracked the status as the tanks were being emptied and filled, as well as before and after completion of each step. Our experts were always available to immediately be on site to complete surveys and keep from holding up the next step in the process. We also used survey equipment that met the rigorous requirements for the scope of work.
