Toquepala is a copper mining community in the province of Jorge Basadre, in the department of Tacna. The mine is run by Southern Peru Copper Corporation, with which Graña y Montero is working on three projects that have made it possible to expand the plant processing capacity from 60 thousand to 120 thousand tons a day.
In these projects, Graña y Montero’s work has been characterized by the team’s cohesion, technical ability and capacity to meet the different challenges that arise daily. Through the experiences of César Rojas, Christian Cahui and Eduardo Trujillano, we would like to share some of these with you.
The challenges we face day to day
César Rojas, Project Manager, mentioned that “In this type of fast-track projects,” engineering and procurement take place as the project is carried out, due to which there are many changes. Therefore, among the continuous challenges we had to face were constant variations in quantities, changes in delivery dates for materials and overlapping activities. To overcome them, we needed to be well organized among all areas and to work closely with the customer. These actions were possible thanks to the principles of unity, professionalism and coordination among the project team!”.
Christian Cahui, Superintendent of Structures and Pipes, emphasizes that “Rain, wind or dense fog could have had an impact on the project due to lack of visibility, electrical storms, wet surfaces or wind that made it impossible to work safely. To minimize these impacts and protect the inside of the buildings, we installed corrugated sheets that allowed us to work without problems.”
Lastly, Eduardo Trujillano, Civil Superintendent, adds that, “Give the shorter times for the movement of earthmoving equipment, loading equipment and high-capacity mobile cranes, we had to hold meetings with different areas of specialization in the project to coordinate activities and take better advantage of equipment and resources.”
Thanks to César, Christian, Eduardo and the entire team, who are making this project a reality and overcoming new challenges every day!
What projects are being carried out in Toquepala?
- The first project consists of civil works and the installation of structural steel for grinding, flotation, regrinding, compressor room, lime slurry tanks, reagent plant, civil works for recovered water reservoir and tanks, thickeners, Nash plant?, filter, and molybdenum.
- The second contract is for the execution of electromechanical works for the intermediate stockpile, crushing, secondary/tertiary classification, and fine aggregate building – dry area.
- Lastly, in the third project, electromechanical works for grinding, flotation and regrinding, compressor room, lime slurry and reagent preparation plant – wet area are being carried out.
Projects such as Toquepala demonstrate the company’s ability to overcome challenges in order to build a better Peru.
