Our expertise

Foundations and ground engineering for major infrastructure

We undertake shallow and deep foundation design, construction and geotechnical investigation studies across three sectors.

Civil infrastructure

Low and high-rise buildings, bridges, elevated highways and railways, and airport infrastructure.

Energy and plant infrastructure

Wind farms, power plants, chemical plants and power transmission towers.

Mining infrastructure

Primary and secondary crushers, ROM walls, stackers and reclaimers, railways, access roads, and fill and cut embankments.

Our services

Adding value at every stage of a project

Geotechnical studies at the feasibility, pre-design and construction phases make owners, designers and constructors aware of the nature and extent of any geo-uncertainties on a site. They help to:

  • Carry out geotechnical design, earthworks and foundation construction in a more timely and informed way

  • Optimise foundation design

  • Reduce short and long-term geotechnical risk on the project

Geotechnical engineering studies

Desktop reviews, interpretive reports, foundation and ground improvement design, investigation scoping and construction support.

Engineering geological studies

Desktop studies, engineering geological mapping, borrow fill management and construction supervision, delivered with our associate consultancies.
