Rehabilitation of TR31, Montague Ashton Lateral Support

Contract Value: 12 400 000

Engineer:  AECOM

Description:

The contract required the upgrading of three bridges along the TR31 road between Ashton and Montagu in the Western Cape. Fairbrother was commissioned to provide a design and supply solution for the temporary lateral support for the excavations of the new bridge abutments & piers. The solution was to install 240mm diameter soldier piles at 1m spacing through the cobbles & boulders and into the bedrock. The piles were restrained using whalers & self-drill nails with shotcrete infill panels. In total 1400m² of lateral support was installed. Fairbrother also assisted with the dewatering of some of the bridge foundations.
