Brownfield Expansion & Mine Upgrades
Expansion and upgrade of existing mining operations requiring tight coordination between ongoing production, new construction works, and controlled management of scope, cost, and disruption.
Greenfield Mine Development
Development of new mining sites involving large-scale earthworks, infrastructure construction, contractor mobilization, and disciplined control of capital costs from early works through commissioning.
ERP for mine development and expansion
How do you build a cost and schedule baseline for a greenfield mine?
Break development into packages such as earthworks, haul roads, utilities and plant construction. Link the Bill of Quantities (BoQ) to work breakdown structure (WBS) activities and cost codes. Use cost recipes to estimate resource quantities, costs and productivity. For a haul road, the BoQ sets the volume to move and the WBS shows when the road must be ready for plant deliveries. Compare measured quantities and actual costs with that baseline.
How do you plan a brownfield mine expansion around ongoing production?
Agree access restrictions, outage windows and tie-in dates with operations. Schedule a conveyor tie-in during an approved outage and plan preparatory work around it. Link the expansion BoQ to its WBS activities to track scope and cost separately from routine production. If the outage moves, review the schedule for idle crews or equipment and potential commissioning delays.
How do you assess the cost and schedule impact of a mine development variation?
Compare the proposal with the approved BoQ and WBS. If revised geotechnical information requires extra excavation and ground support, add sub-items under the affected BoQ item, estimate additional labour, plant and materials, and link the revised quantities to the affected WBS activities. Link the geotechnical report, revised drawings and site records for authorized reviewers. After approval, record the revised baseline as a new version so the original remains traceable.
