Supervision of construction of dams ensuring static and seismic stability of tailings deposit. Deliverables include monthly monitoring reports, monitoring final report and report of settlement work.

The main construction works include 04 earth dams, 03 respective vessels and 03 reinforced concrete retaining walls. The maximum height of each of the 04 dams varies between 22m and 28m with respective crown levels varying between 3,467 and 3,451 meters above sea level. The respective concrete retaining walls have an overall length of 705m together.

In additionally to the construction of dams, it was necessary to derive the waters of the Huallaga river through a tunnel of about 1km in length.
