Geotechnical Investigations

SMEC incorporates engineering geological and geotechnical site investigations as a core product in the design and delivery of construction projects. These services remain the primary source of information that forms the basis of foundation design.

SMEC offers a holistic site investigation service from inception to report delivery. SMEC’s engineering geological and geotechnical capabilities cover a range of investigation techniques and include an operational base with a nationwide and worldwide footprint.

Investigation Project Cycle

Geotechnical investigations are undertaken from pre-feasibility and feasibility studies to detailed design, construction, post-construction and remedial stages of the project cycle. These phases are carried out in compliance with relevant technical standards, and codes of practice and legislation, to aid in determining engineering properties of materials and stresses in rock and soils.

Specialist Services

SMEC’s engineering geological and geotechnical division has experience in large commercial, parastatal and internationally funded projects, giving us the capability to work on multi-disciplinary and more specialised projects. These capabilities include:

  • Comprehensive desk studies
  • Site investigations
  • Laboratory testing
  • Dolomitic stability investigations and risk management strategies
  • Housing developments to National Home Builders Registration Council specifications
  • Development of materials sources
