Conceptual, basic and detailed engineering to increase the storage capacity of perforation samples.

Between 2012 and 2016, Antamina is conducting an exploration campaign that will require storage of 120,000m of drilling samples per year. GMI was hired to develop the conceptual, basic and detail Engineering of the 7 and 8 zones, located at the south of the current core shack platform in the Yanacancha camp.

The detailed engineering studies optimized the drainage designs presented in the basic engineering with the development of more economical technical solutions. In addition, an improvement was made on the accuracy of the material take off (MTO) and earthworks quantifications, drainage works, concrete works, metal structures, supply and improved electrical connections.

Earthwork MTO was updated with the survey data of the soil mechanics report, as well as the development of construction plans with the necessary detail to minimize the technical queries and modifications to be made during the work execution.

With all these adjustments it was possible to update the project CAPEX with a level of accuracy of +/-10%.

Detail engineering of seepage pumping line relocation.

Due to the steady expansion of the tailings dam, the seepage pumping system needed a change that covered the required flow rates. To do so, the system was moved out of the future projection of the tunnel decant extension.

The modified system corresponds to the facilities from the seepage pumping station, up to the booster station, and the development of complementary works for the relocation of pipelines and accessories required for a proper future operation.

The second stage was developed between September 2009 and February 2010, Construction commenced in March 2010 and was successfully completed in October 2010.

In this project, the use of 3D technology was the key to develop a quality product since interferences were detected on time and appropiate actions for constructability were defined.
