Determination of mix-designs to meet client requirements;
Supply of plant and equipment;
Procurement of all raw materials:
Sole supplier of 250,000m3 of readymix concrete; concrete pumping; concrete testing.

Procurement of adequate raw materials to this remote location was achieved through the use of a purpose-built 7,000 MT cement terminal fed by 2 x 5,000 MT bulk cement vessels. The cement was then trucked along a 70km semi-permanent road to the project site in purpose built 40MT tanker trucks. Aggregates were barged from neighbouring islands or hauled from the west coast of Sumatra by tipper trucks.

Other challenges included supply to a 300 m3/day prestress-beam and shear-wall plant where each bed was turned around within 24 hours. Supply of high-quality concrete was maintained without any failures over the 6 month period of peak operation.
