    PAS128 Utility Surveys

    We can detect and map metal pipes, plastic pipes, electricity cables, drainage systems, telecoms, traffic signalling, and fibre optic cables, using a range of techniques including:

  • CAT scanning (specifically Radio Frequency/Electromagnetic Location, or EML);
  • Ground Penetrating Radar (GPR) with multi-frequency (200 to 600 MHz) and multi-polarization antennas;
  • Visual inspection, cover lifting, sounding, and consulting statutory records.

    Alongside our topographic survey expertise, we are capable of creating a comprehensive model of above and below-ground details.

    Applications include site-wide surveys or clearance at specific excavation locations.

    The survey work is conducted in accordance with the best accepted current practice and complies with the requirements of PAS 128:2014 – Specification for underground utility detection, verification, and location.

    Laboratory Assessments or Consultancy for Your Project?

    In addition, we also undertake a variety of specialised investigations relevant to geotechnical and contaminated land assessments.

    Contaminated Land Assessements

    Land Science can assist with contaminated land assessments as part of a planning application or any other purpose prior or during house building, commercial development or creation of new infrastructure.

    Land assessments are often required to assess soil contamination or groundwater pollution issues amongst a host of other potential problems. We assist at all phases of the assessment process with comprehensive desk studies, site investigations, contaminated land remediation and validation and post remediation monitoring.

    Geotechnical Support

    Land science provides geotechnical investigations which will help you to make informed decisions about the design of pavements, foundations and drainage on your project. Our in-house geotechnical laboratory testing capability enables us to undertake a range of sample analysis in-house.

    Where more specialised geotechnical testing is required, we have a range of trusted preferred partners that we call upon on a regular basis.
