KS Associates contracted with the MWH/Hatch Mott MacDonald Joint Venture (MWH/HMM JV) to perform surveying for the design of the Dugway Storage Tunnel (DST). Surveyors performed an as-constructed survey of the Euclid Creek Tunnel (ECT) “tail tunnel” where it would connect with the DST, more than 200 feet below ground.
The survey team used 3D laser scanning to scan survey control point targets at the top of the shaft, and from the bottom of the shaft through the tunnel to the ECT’s terminus. Not only did this save time and minimize disruption to the ECT contractor, the scanner can operate in complete darkness and obtain all necessary survey data of the 24-foot diameter tunnel to the end of the excavation. The entire scanning operation took less than five hours. The amount of data captured by the laser scanner provided a high degree of accuracy to execute a project with an extremely low tolerance for error.
KS Associates also prepared surveys and easement documents for 19 easements needed to construct the tunnel and access shafts. Additionally, KS Associates completed Maintenance of Traffic (MOT) plans for the project.
