Tetra Tech Proteus was lead designer for the detailed engineering phase of the AUD 65 million Tanami Expansion Project, a throughput upgrade for the Newmont-owned Tanami gold mine in the Northern Territory of Australia. The objective was to increase production of the 20-year-old processing plant from 2.3 to 2.6 million tons per year and improve safety by implementing a significantly safer method for producing the mine backfill material.
The project team used OpenPlant and AECOsim Building Designer to model all aspects of the as-built plant by quickly converting existing legacy 3D models in a variety of formats together with point-cloud information. OpenPlant PID enabled quick and easy generation of all P&IDs and provided an efficient means to retain and modify the intelligence attached to the P&IDs as design changes occurred. The team used OpenPlant Modeler for the piping and AECOsim Building Designer for the structure and concrete. Cached views enabled the automatic generation of annotated plans and elevations of the plant in five hours per drawing, rather than the average 40 hours per drawing, and generated piping isometric drawings in one hour rather than three. The team used ProjectWise to share information among project disciplines, and Bentley Navigator to identify potential operational and maintenance issues.
This pre-feasibility (FEL2) study investigated available options for adding a lump rescreening plant (LRP) to an existing iron ore export terminal in Whyalla, Australia. The LRP screens the lump iron ore product to achieve export specifications. This project provided Hatch with the first project opportunity to use, test, and validate Bentley’s MineCycle Material Handling software after participating in the syndicated development of the product.
To fit the LRP into the constraints of an existing brownfield operation, the team created a terrain model of the existing facility using Google Earth Professional and overlaid a high-resolution image from the client on the terrain model. Importing this project terrain into MineCycle Material Handling saved time normally spent on requests to the civil department to receive terrain models. The technology’s ease of use enabled junior designers to provide clear designs to the client, reducing labor costs. Moreover, MineCycle Material Handling improved efficiency by 40 percent when compared with traditional workflows and engineering applications. Using ProjectWise allowed the geographically dispersed team access to accurate, real-time data and proactively share input.
On this EUR 25 million project, OAO Magnitogorsky Gipromez is responsible for the general design of the modernization and technical upgrade activities for the LPC-11 complex of OAO Magnitogorsk Iron and Steel Works. The objective of the upgrade project is to meet the needs of manufacturers of high-quality body sheets to be used for car exteriors and household appliances. This includes coated (galvanized) sheets that are an extension of cold-rolled product grades.
The electrical design team used Bentley Raceway and Cable Management integrated within a 3D model covering all other disciplines – heating/ventilation, ventilation/air conditioning, construction/architectural design, and technological design. The application allowed groups of users to work simultaneously in a common work environment, which increased productivity by 15 to 20 percent. Using Bentley Raceway and Cable Management accelerated the overall design process by 30 percent.
