Project Complications & Achievements

Sourced a ‘modified’ PM3/20QG material with a higher than normal P.I. to provide greater longevity to the pavement.- Worked closely with broad spectrum and Defence operations to minimize disruptions to all Defence scheduled activities during the course of the contract works.-We initiated the roll out of an indigenous training initiative where we assisted local indigenous members of our workforce to gain machine tickets while working on the project. Shamrock maintained an indigenous participation rate of greater than 23% for the duration of the project.
