Construction Sciences is an international construction materials testing, environmental services, subsurface utility engineering and geotechnical engineering firm delivering multidisciplinary services across the construction industry.

Subsurface Utility Engineering (SUE)

Subsurface Utility Engineering (SUE) is an engineering process that combines civil engineering, geophysics, survey and computer-aided design and drafting (CADD)/geographical information systems (GIS). Information on the location and condition of subsurface utilities is collated and assessed to reduce the occurrence of interference and conflict with valuable infrastructure.

Project and utility owners, designers, engineers and contractors can significantly benefit from adopting a SUE process during the life cycle of a project to avoid:

  • Unexpected costly utility conflicts;
  • Project delays;
  • Utility damage;
  • Community issues; and
  • Contractor claims.

Our experienced and accredited team of surveyors, engineers, industry technicians, operators, professional utility coordinators, data depiction analysts, project managers, and confined space trained personnel provide an integrated SUE service combining:

  • Preliminary/desk top research to obtain existing utility information.
  • Surface geophysical methods to identify the approximate alignment of subsurface utilities, including:
    • Electromagnetic detection; and
    • Ground penetrating radar.
  • Non-destructive digging (vacuum excavation) to expose subsurface utilities at critical points, obtaining their exact coordinates/location and attributes.
  • Survey and depiction of subsurface utility data with in-house capabilities to output in various formats such as AutoCAD, 12D and/or GIS.
  • Professional utility coordination throughout a project life-cycle.
