Sundance Resources’ Mbalam Iron Ore Project is a new major mining project straddling the border of Cameroon and Congo. At Calibre’s request, Brown Consulting has provided hydraulic and structural details for the project’s railway alignment, which stretches over 500km. This significant alignment includes 13 bridge crossings and 15 culvert crossings, with both road and rail bridges considered at these locations. Both culvert and bridge solutions were developed at a number of locations for comparison purposes.
