CGC were the Geotechnical Advisors for the construction phase of the $812.95 million Bruce Highway Upgrade – Caloundra Road to Sunshine Motorway (CR2SM). The project involved upgrading the this section of the Bruce Highway to six lanes, as well as major upgrades to both interchanges and the delivery of a two-way service road for local traffic. 

The upgrade includes construction of 23 new bridges and culvert structures, cuttings up to 15 metres high and embankment construction over compressible and reactive sub-grade materials within a highly constrained brownfield environment. 

CGC's geotechnical services included value engineering and trouble-shooting, materials suitability assessments, temporary works design, settlement and stability assessments for ground treatments and reinforced earth walls, independent assessment of slope stability, subgrade certification and ground surface treatment advice.
