“A thorough GI of a slope is effective in directing the method of stabilisation, provides an assessment of how safe the slope/ground conditions are for temporary work and construction, and can provide a more efficient design,” Richard explains to readers. “With ageing infrastructure and slope failures becoming increasingly common, good ground and site investigations are important.”
Richard admits that by their nature slopes are difficult areas to access but highlights the bespoke slope-climbing and modular rigs that have been developed by GI companies that are able to provide true geotechnical investigation without compromise.
“Traditionally, these sites typically required the design and installation of platforms using scaffolding to service a cut-down cable percussion or rotary rig,” Richard explains. “However, many GI companies have now developed bespoke drilling rigs, which are better able to access restricted sites.”
Central Alliance has developed a range of drilling rigs that are able to access restricted sites and provide the high quality geotechnical data required by design engineers.
“No matter how difficult or remote the slope, site or location, high-quality GI is possible,” Richard concludes. “Given how essential it is in effective slope stabilisation design today, there are few reasons not to use it.”
