The team is experienced with many years at the forefront of the industry, useing a multi-disciplinary approach to basic design, issues and problems.


Our team of dedicated pipeline field surveyors understand the challenges of long distance pipeline survey and have systems in place that ensure final data is right and fit for purpose.

Design & Construct

This allows pipelines to be designed and constructed without a hitch. Pipeline survey and specific grade design potentially reduces Low Point Drain costs and certainly provides better pipe flow performance and pumping energy savings across the lifetime of the pipeline.

This is done by assuring the High Point Vents are accurately located in water lines and Low Point Drains are accurately located in gas lines, with small highs in natural surface profile being graded through.

Full Survey Capability

The business continues to innovate using latest technology to provide a full survey capability and is fully integrated with our Geospatial Information Systems (GIS) to provide:

  • Real-time spatial date to engineering teams at all locations
  • Support and maintain all spatial software for field and office teams, e.g ArcGIS framework
  • Establish and maintain all engineering design linkages and relationships with geospatial datasets
  • Provide spatial products such as mapping, digital data, spatial analysis, etc, as required
  • Ensure all spatial data is secure, version controlled, and available to end users
