WSP Opus geotechnical has a reputation for technical precision

Geotechnical engineering is a branch of civil engineering that focuses on earth materials. Our geotechnical engineers provide a strong foundation for development and infrastructure projects.

WSP Opus’ geotechnical team can investigate ground conditions to determine soil and rock properties, assess how proposed construction projects will interact with the ground, and design foundations to support structures.

Many of our engineers and geologists are internationally recognised and bring invaluable experience and understanding to our clients’ projects. Our past and current clients have included central and local government, commercial clients, developers, contractors, private clients and other consultants.
