Scope Of Work

GIS Solutions performed Data Clean Up and Quality Assurance data checks on Supply Systems 1-7.

This massive project involved the checking of 9,159km of Pipes and Fittings. We developed and executed a procedure of tests to search for errors and problems in the “As Constructed” data supplied by the contractors who installed the materials.

Included in these tests were such test as:

  • attribute tests (e.g invalid pipe materials)
  • logical problems (pipe sizes not matching fitting sizes)
  • topology errors (floating fittings, duplicate data)
  • geometric network (disconnections, invalid flow directions)

Tens of thousands of errors and mistakes were identified and rectified to allow trusted use of the data for decades to come.
