INNOVATION IN mININg AND mETALS
SEI Engenharia Ltda
Vale, the second largest mining company in the
world, is building a $2.6 billion copper plant in
northern Brazil that will produce 16 million tons
per annum of run-of-mine with average annual
production of 340,000 tons of copper concentrate.
SeI engenharia was contracted to perform front-end loading and deliver a 3D model, which was
unprecedented at Vale.
The 3D models were used to advance the concept
studies during the detailed design phase, which
helped achieve the goal of accelerating project
execution. model reviews gave plant operations
early input in the project. The models also
shortened design review sessions and approval
processes. Schedule simulations saved resources
SeI trained a multidisciplinary design team to use
microStation, Bentley Architecture, Structural
modeler, Inroads, and Bentley navigator for
modeling infrastructure, concrete structures, steel
structures, substation, and industrial installations.
Several plant layout simulations, including options
for internal and external access roads, were
analyzed to reduce total costs. The integrated
workflow saved about 5,100 man-hours and reduced
front-end loading costs by $400,000.
