Dowding Reynard & Associates — Everest South Platinum Mine

Dowding Reynard & Associates designed a technologically advanced recovery plant in Africa that includes a primary crusher. The sized material proceeds through a two-stage milling process and flotation concentration. The final concentrate is dried in a filter press to a 12-percent moisture content. A total of 72 pumps will service the concentrator plant.

The design phase commenced in July 2004, spanning a period of 40 weeks, overlapping into the initial construction phase in October 2004. A tightly managed construction program helped make it possible for the facility to be commissioned in November 2005.

The design team used AutoPLANT Structural and Piping to generate 772 isometric lines and arrangement drawings of 854 tons of structural steel. Both 2D and 3D CAD models were created in conjunction with a project database, which allowed the firm to extract bills of material. In addition, the production of annotated 2D drawings and piping isometrics was an important factor in helping Dowding Reynard & Associates achieve its project deadlines.

Bentley Explorer enabled the firm to conduct regular multidisciplinary review sessions during which the project was accurately visualized. Moreover, the application's clash detection system enabled the engineers to eliminate problems at the design stage.
