TCD were engaged by NRW Civil and Mining as part of the BHP Billiton RGP5 South Duplication – Chichester Deviation Project

TCD’s subcontract package included the supply and install of corrugated steel pipe culverts. It was a big undertaking with a total cumulative length of over 4 kms in culverts, ranging in size from 600mm to 3,600mm in diameter. They’ve been built to last with the supply and placement of cement stabilised backfill and the placing of rock protection at the culvert locations.
