Investigations for large civil engineering projects, including port facilities, container terminals, airports, coastal structures, highway construction, bridges, sports stadiums, water storage reservoirs, dams, buried pipelines, tunnels, landfills, marinas and large residential or commercial developments.

Site investigations are carried out as per AS1726 Geotechnical Site Investigations and field/laboratory testing carried out in accordance with AS1289 Methods of testing soils for engineering purposes. Services include:

  • Soil and rock logging;
  • Sampling for laboratory testing;
  • Field testing including Dynamic Cone Penetrometer (DCP), Perth Sand Penetrometer (PSP), Standard Penetration Test (SPT) and Cone Penetration Test (CPT);
  • Interpretation of soil and rock profile, condition, quality and relevant engineering parameters;
  • Watertable identification including initial depth, piezometric depth, drawdown, and sampling including pH, Clorides, Sulfates and contaminants just to name a few;
  • Design and construction recommendations for residential, commercial and industrial structures;
  • Investigation and/or assessment of dams, lagoons, wetlands, drains and wastewater storages;
  • Investigation and design of retaining and/or reinforced earth retaining structures.
