CARRINGTON RD BOULDER RETAINING WALL DESIGN

GT Geotechnical was engaged by City of Gold Coast Council to undertake a detailed geotechnical investigation and retaining wall design along council water asset infrastructure to support upgrades to stormwater infrastructure for the City. 

Our scope focused on characterizing subsurface conditions, developing a site-specific ground model, and identifying geotechnical risks relevant to the long-term performance of the asset. Field investigations identifed shallow rock, residual soils and uncertified fill. Based on these findings, GT Geotechnical provided clear, construction-focused recommendations to inform the design of an engineered boulder retaining wall, including temporary works design to safely construct the wall.
