REE recently completed an extensive overwater and on-land geotechnical investigation for a new mine development in remote North-Queensland. REE utilised ‘Tablogs’ an intuitive cloud-based borehole and testpit logging software to provide real-time geotechnical data to the hands of our designers and client in order to accelerate the design process, provide increased oversight from our senior…

Limit equilibrium analysis (LEA) for slope stability assessment became popular since Bishop’s method of slices was first introduced in 1955, followed by a number of variations. Although advanced numerical methods such as finite element analysis (FEA) or finite difference analysis (FDA) have been actively developed since personal computers became available, engineers keep holding on to…

Recently Red Earth Engineering (REE) has been involved with detailed geotechnical investigations and grouting trials for a proposed 1.6km long by 18 m deep grout curtain which is to be constructed below a new tailings impoundment dam. REE was responsible for designing and executing a series of grouting trials. The purpose of the trials has…
Read moreREE is supervising concurrent Geotechnical Investigations (GI) at two sites, one in the Northern Territory and one in Queensland. The GI’s are addressing the challenging soil conditions at the sites by employing a range of in-situ testing and sampling techniques undertaken by specialist subcontractors. REE’s role has included oversight of the GIs and technical expertise…
