Overview

The Conga project is an open pit copper/gold mine. The project covers a vast area of approx. 6000 ha and involves a substantial amount of earthworks infrastructure in a remote area of the Peruvian Andes. The average elevation is approximately 3800 m and there is significant water management required during the wet season where annual rainfalls can exceed 1.2m.

Facilities

• 20 water storage dams, tailings dams, and sediment ponds
• 25 km of water diversion channels
• 70 km of permanent and temporary roads
• 25M m3 of contractor excavated earthworks
• 10M m3 of Mine Operations supplied rock fill for earthworks structures

Services

Survey Data Control, Cadd Modeling and Site Mapping:

• Survey data and Cadd Modelling management – collate data from multiple survey groups, overall site map information management, as-builts, quantity and quality control for contractor payment, and aggregate quantity management
• Management of survey groups
• Prepare maps and related print media for use in public social presentations

Value Engineering / Constructability:

• General design reviews for constructability
• Integration of Mine Operations resources to provide less expensive bulk rock fill to earthworks structures
• Alignment optimization of roads and other liner structures to reduce excavation and fill quantities
• Cross-sectional evaluations and adjustments of earthworks structures to provide greater ease of construction
• Sequencing of works to provide adequate basin sediment control
• Standardization of aggregate product specifications between multiple designers

Civil and Earthworks:

• Estimate and contract package preparation support
• Supervision of earthworks construction
• Interface between Owner, Engineer, and Contractor
• Coordination between Mine Operations and earthworks contractors
• Site wide water management and sediment controlSelection of works for local contractors and coordination of local contractors scope within the activities of the primary earthworks contractor

Project Controls:

• Quantity, Cost and Schedule monitoring
• Material and Equipment management
• Management of processed aggregates
• Quantity and quality control of earthworks volumes
