Successful completion of one of the globe’s five largest copper mines

For more than six decades, Bechtel’s Mining & Metals Global Business Unit has successfully completed hundreds of major projects in the most challenging conditions. 

One of the most recent was Las Bambas, a greenfield copper concentrator project in the Peruvian Andes operated by MMG. This world-class mine is expected to produce up to 460,000 metric tons of copper in concentrate in 2017, its first full year of operations.

  • Thanks to the comprehensive environmental management system Bechtel developed, there were zero environmental impacts during the construction phase
  • Construction of a permanent works plant began in 2012 and mechanical completion was achieved in 2015

  • Las Bambas is located in southern Peru’s Apurimac Region, approximately 125 miles (200 kilometers) from Cuzco
  • Bechtel completed more than 3,000 hours of traffic safety training in the construction area near the concentrator and along the heavy-haul road
  • As the rural communities were not used to the high-volume of road traffic, Bechtel completed 59 workshops for 2,224 schoolchildren

Keeping kids safe

The rural communities were not used to the high-volume of road traffic that came with the project's construction. To ensure safety for all, we completed 59 workshops for 2,224 schoolchildren and 3,098 hours of traffic safety training in the construction area near the concentrator and along the heavy-haul road.

For more information about our successful work with the communities at Las Bambas, please see Bechtel's 2016 Sustainability Report.

Standard concentrator design reduces costs and expedites delivery 

In 2012, Bechtel completed a copper concentrator at the nearby Antapaccay Project. We drew on this experience to build the facility at Las Bambas, Bechtel’s largest greenfield concentrator to date. We implemented a standard plant design at the two sites, which helped reduce capital costs and delivery times, leverage good practices, and promote consistent implementation of environmental, safety, and health processes, recruitment practices, community engagement efforts, and local enterprise support. 

Building local the economy, industry and skills

During the course of the project, Bechtel and its partners spent more than $78 million on local goods and services in 16 remote Peruvian towns. Indirect employment from these ventures alone exceeded 1,500 jobs.

In addition, we provided approximately 5,000 hours of training to more than 600 businesspeople on topics such as customer service, business management, production processes, environmental, safety, and health standards, and tax preparation.

It was important for Bechtel, our customer, and our partners to help local communities succeed in the changing economy. We also guided local firms to join forces through business-to-business cooperation to capitalize on economic opportunities. For example, laundry and hotel owners formed associations to negotiate higher quality and safety standards with the project. Bechtel was recognized by 10 vendors for helping them meet the requirements of food hygiene, water and sanitation, fire prevention, and evacuation needed for project work. Many of these standards were developed and delivered through training, site inspections, and improvement plans. The association also pledged to continue improving these practices after Bechtel left the project.

Together with our customer and partners, we also made a concerted effort to elevate the technical skills of local people through various initiatives. For example, in 2013 more than 160 workers completed the formal trade craft and on-the-job training essential to be qualified for higher-level positions, such as surveying, earthworks, and welding.
