While we were working with NRW Civil and Mining, installing culverts on BHP’s South Flank Construction Project, BHP requested the installation of an additional DN2400 multiplate culvert on the Southern Haul Road of the project.
This was no ordinary culvert. It measured 165m long and we needed to place the riprap to headwall and culvert apron as part of the variation. We completed the project on time and on budget and used a staggering 10,000 bolts.
