To construct the main substation platform, we were tasked with the excavation of 120,000m3 of weathered and dolomite rock. This process utilised both our in-house operatives and plant, before crushing the material as part of our cut-to-fill operation that would create the final platform.
An additional challenge was the presence of live overhead high voltage power lines situated adjacent to the site. Through extensive liaison, careful planning, and full supervision, this obstacle did not hinder successful completion of the earthworks.
Once the earthworks were completed, a process of settlement monitoring was undertaken to ensure that the platform remained within tolerance during the substation commissioning phase.
