Why Tarnwick

Why developers and councils choose Tarnwick

  • Our own fleet, ready to mobilise. We own the machines we run and maintain them in our own workshop, so we mobilise when the project needs us rather than when hire equipment is free.
  • Survey checks at every stage. Our surveyors set out each stage and check levels before the next one starts, so errors are found early and the work passes inspection the first time.
  • One supervisor for the whole job. The same supervisor runs the site from the first cut to handover and reports to the client each week on progress, weather and any changes.
  • Programs planned around the weather. We plan the wet season into the program, stage the works to keep water off finished areas, and set up erosion controls before the first storm.
