Southeast Calgary Connector and East Calgary Connector


For the Urban Pipeline Replacement Program, ATCO Pipelines constructed two pipeline segments: the Southeast Calgary Connector, a 13.4 kilometer, 610 millimeter natural gas transmission pipeline and the East Calgary Connector, a 8.7 kilometer, 762 millimeter natural gas transmission pipeline. WSP:

  • Imported the surveyed pipeline as-built data into a geodatabase. The geodatabase contained geospatial features such as pipe information (heat, joint number, grade, wall thickness, etc.), welds, bends, coating repairs, cathodic protection, etc. and can be viewed online or through the user’s desktop GIS software as part of their information management system.
  • Collected inspection reports for the bends, HDD’s, MTR’s, crossings, radiography and tied them to the geographic coordinates within the geodatabase. This enables the client to digitally store and reference the report to the geographic locations of the pipeline feature.
  • Used a laser scanner, which records the x,y,z at every centimeter — this approach gave ATCO the most cost effective as-built of the facility. This point cloud is then imported into AutoCad for further analysis and modeling. WSP provided ATCO with an interactive 3D PDF allowing the user to zoom and rotate the site within the PDF. Additionally, the user can use the measuring tool within the PDF to extract as-built information.
