LASER SCAN AND ENGINEERING DRAWINGS FOR BOARDWALK PIPELINE

Dale Stockstill & Associates was hired by Boardwalk Pipeline to provide 2D Plan and Section piping drawings for upgrades to be performed at two sites in their Jackson Yard facility. DS&A used their Topcon GLS 1500 High Definition Laser Scanner to scan the two areas where the work will be performed. The existing pipes, valves, walkways, racks and footings were traced by Aaron Lee, a DS&A technician, to provide the initial existing condition plans to be used by the BWPL engineer for his design. DS&A will also provide the Demolition, Construction, and  As-Built drawings for these two projects. The use of the GLS 1500 enabled DS&A’s crew to do all the preliminary surveying necessary for the projects in one day- a project that would have taken 3 to 4 days of conventional surveying.

HIGH CONSEQUENCE AREA (HCA) SURVEYS FOR BOARDWALK PIPELINE

Boardwalk Pipeline hired Dale Stockstill & Associates’ to provide preliminary and pre-construction surveying for 3 sites in the Mobile, Alabama area that needed to be Hydro Tested for compliance with DOT High Consequence Area regulations. The sites consisted of a school, a church, and a nursing home facility and the 10” High Pressure Gas Pipeline that is buried near each. DS&A’s crew located and probed the pipeline along each site reestablishing the pipeline stationing by comparing features such as vents, road crossings, etc. to their original stationing per the 1950’s era alignment sheets. After their preliminary surveying on each site was done, the crew went back to meet with representatives from CharCo, the contractor who would be performing the hydro tests, and Boardwalk Pipeline representatives and inspectors. The crew staked the HCA limits and also placing stakes at each Potential Impact Radius (PIR) point which were calculated from precise locations of the impacted buildings as they relate to the existing pipeline. The crew also located existing utilities which were located by the “OneCall” requested by Boardwalk Pipeline and CharCo.
