McTish, Kunkel and Associates (MKA) provided construction and as-built surveying services for this extensive natural gas pipeline gathering system. MKA used five full-time survey crews working with four contractors during the construction of this pipeline gathering system consisting of 17.5 miles of 24-inch pipeline, 7.6 miles of 16-inch pipeline and 3 miles of 8-inch pipeline, built from July 2015 to February 2016. MKA survey crews were directly responsible for locating, tracking and chaining all of the pipe and materials used in the mainline portion of this pipeline system, excluding valve sites fabricated off site.
- The project involved environmentally sensitive areas that required detailed topographic surveys of four steep stream crossings. Site plans depicted the disturbances and helped facilitate the design of a stabilization plan for the steep slopes on each side of the sensitive stream crossings.
- MKA’s survey teams were on site for the duration of the project. MKA helped the contractor and client with additional staking in sensitive wetlands, marking property lines for reclamation and fence building, marking the pipeline for installation of pipeline markers, determining grades and elevations for fast set up of bore pits and obtaining grades and elevations for installing a wire line for one of the steep ravine crossing pipe installations.
- MKA prepared as-built pipeline profiles to aid in developing hydro-test plans, testing pressures, and test break points. MKA’s surveyors were instrumental in working with the integrity group. After a smart pig had been run, MKA was able to calculate the position of the anomalies (dig ups) and provide stakeout for the quick and efficient replacement of damaged portions.
