This Contract was at Speed Creek located within the Australian Defence Force TFTA site. Previous construction had not been adequate to stop undermining of the existing abutment and CivilPlus were engaged to construct the new design. This design required placement of select fill in conjunction with geo synthetic layering to provide the new foundation for the abutment hydrology formation. This was then armoured with 300-500mm rock and the top 1.5m concrete grouted to provide the required protection.
