Melbourne Cement Facility Silo

Slipform

Structural Systems (Construction) based in Melbourne, Victoria were contracted to work on the new Melbourne Cement Facility silo. This state of the art cement storage silo, located at Port Melbourne and with a capacity of 35,000 tonnes, is the latest addition to Melbourne�s largest supplier of cement. The Melbourne Cement facility currently supplies 80% of the cement required for over five ready-mix companies. The new Cement Silo will have the ability to load three tanker trucks within its perimeter simultaneously.

The silo has been designed by Shedden Uhde, a leading designer within this field. Some notable technical points for this project are :

� Capacity 35,000 tonnes

� Height 57 metres

� Diameter 30 metres

� Wall thickness 900mm reducing to 450mm

� 535 Tonnes of reinforcement

� 130 Tonnes of Post tensioning

� Cubic Metres of concrete

Structural Systems successfully bid the project using an in-house Slipform System. This coupled with the BBR multistrand post tensioning system was seen by the client as the best solution for a difficult project with a tight program.

The slipform pouring cycles were run using 2 shifts working 12 hours each. As the slipform is a continuously moving formwork system climbing at a rate of approx 200mm per hour utilizing a total workforce of 30 men including concrete placers on each shift. It is imperative that the preplanning is carried out with meticulous care. If a component is missing or fails at 2.00am in the morning the consequences are dire.

Structural Systems with its experienced and motivated workforce completed the project on time and within budget. With several more similar silos planned throughout Australia, Structural Systems are looking forward to continuing the successful SSL Slipform-BBR partnership.
