Cementation engineering involvement in Xstrata Nickel's Nickel Rim South project began with the active participation in the early scoping studies followed by the subsequent pre-feasibility and detailed feasibility engineering. Cementation’s feasibility engineering efforts helped to define the project execution plans and to ultimately receive board approval for the project. The project involved the design and construction of two concrete lined shafts which were sunk concurrently; a 6.1m diameter ventilation shaft to a depth of 1680m and a 7.6m diameter main access shaft to a depth of 1733.5m. The construction also included the main shaft stations on three levels that were developed concurrent with the shaft sinking. The decision to sink two shafts concurrent resulted when it was demonstrated in feasibility that the added capital cost would improve project economics by allowing the earliest possible start to lateral development required for deposit definition.

Cementation’s engineering department also completed the detailed design engineering required for shaft construction and related infrastructure. Detailed design work included the headframes, shafts, hoisting plants, surface support infrastructure, sinking equipment, material handling and dewatering systems.

The success of the Nickel Rim South is an example of Cementation’s partnering approach and design build and best for project philosophy.
