Situated about 90 kilometers west of Johannesburg, South Africa, the
AngloGold Ashanti Savuka mine is the second deepest gold mine in the world
at nearly 4 kilometers. In 2009, a seismic event and its aftershocks severely
damaged the shaft and infrastructure. Underground dams burst, flooding the
shaft and destroying equipment. The $30 million refurbishment project took
nearly 14 months to restore operations.

microStation and Structural modeler were used to model the underground
landscape as well as four conveyer systems, steelwork at the silo and load
station, control chutes at the silo, and loading flasks at the shaft. This enabled
the project team to ensure that equipment and components – some weighing
several tons – could be packaged in subassemblies that would fit through the
tunnel system and be installed in the allotted space.
Fortescue metals Group enlisted T&G corporation to help develop the $630
million crushing plant in Western Australia. T&G performed engineering design
for steel, concrete, mechanical, electrical, ducting, structural, and civil works.
T&G streamlined the workflow by directly linking a 3D model to 2D drawings
for design, review, and production of 2D shop detail drawings for construction,
which occurred concurrently.

proSteel was T&G’s primary software. Working with the 3D model enabled T&G
to visualize and communicate design concepts, and perform clash detection.
proSteel integrated seamlessly with other software, enabling T&G to add value
for Fortescue metals Group. modeling in 3D saved an estimated 30 percent in
time compared to designing solely in 2D, with an overall cost savings of about
