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.

Laser Scanning the Homochitto River

Dale Stockstill & Associates were hired by Garver Engineers to provide a 3D As-built of the bridge across the Homochitto River in Franklin and Wilkinson County, Mississippi. The project area contained a dangerous bluff that was constantly caving in to the river which made it too dangerous for a conventional crew to approach. DS&A’s crew used a combination of Scanning and conventional surveying to survey the bridge and the river bed up to a 1500’ feet on each side of the bridge. The deliverable was a 3D Microstation V8i drawing along with a TIN and contours.

Talsen Engineering/IMTT Laser Scanning the Asphalt Pit

Dale Stockstill & Associates were hired by Talsen Engineering to provide High Definition Laser Scanning and 3D Modeling for a project in International Matex Tank Terminal’s St. Rose Facility. The proposed asphalt pit needed several large pipe runs that began at a certain flange, ran to the proposed pit, then back to and parallel with an existing group of pipes. The proposed route then had to cross a busy section of pipes and go under a road in a specific tunnel turn several times to avoid more existing pipes eventually tying in to an existing flange. DS&A’s Laser Scanning crew was able to set control and collect all the data necessary for the project- spanning over 900 linear feet- in one day. The data collected by the scanning crew would have taken more than a week to collect conventionally. DS&A delivered a topo survey with 1’ contours along with a 3D model of all the pipes, risers, bents, tanks, roads, tunnels, and cable trays in the work area.
