Vizcachas Dam in Quellaveco Mine, Peru

The project: Vizcachas Dam in Quellaveco Mine, Peru.

Alsina´s Formwork delegation in Peru began in 2019 its collaboration in the construction of the Vizcachas Dam, located in the Quellaveco mining project in the Moquegua region, in southern Peru.

This civil works project consists of the construction of the dam with concrete compacted with a roller and formed by the body of the dam, with a height of 41.30 meters and a crowning length of 269.37 meters. The project also includes the construction of the catchment tower, the drainage tower, canals, galleries and other auxiliary structures.

The dam, which will be completed in 2020, will store up to 60 million cubic meters of rainwater, and annually deliver 28 MCM, of ​​which Quellaveco will use 4 MCM, while the rest will be distributed for the benefit of the population. Thus, one of the beneficiaries will be the Tambo Valley, which will receive an average of 10 MCM of good quality water, which will mean a significant improvement in the quality of the water resource.

Alsina: safe and effective solutions for civil works

The main formwork system that Alsina has chosen to carry out this work has been the Alisply Walls Handset formwork system along with the Multiform system, since the versatility of both of them allows to effectively solve the different geometries that arise in a project like this. Alsina has also provided its one-sided climbing system, compatible with Alisply Walls Handset, in addition to the AR-80 Shoring system.

Alsina’s Alisply range includes several recoverable formwork systems for the construction of walls and columns. This is a resistant, versatile and compatible system with all other accessories from Alisply family systems, a fact that makes so much more profitable the formwork equipment on site.
The formwork surface of different types of Alisply is made of plywood, which offers many advantages over metal surfaces, such as lower weight, higher concrete quality, increased performance and greater resistance to inclement weather.

On the other hand, Alsina’s Multiform system, consisting of double UPN metal beams, wooden beams, strips and turnbuckles is one of Alsina’s most versatile systems, allowing “ad hoc” design of the necessary recoverable formwork to adapt to any geometry whether they are straight, curved or one sided walls, lintels or bridge boards.

Location: Moquegua, Peru.
Implementation Date: 2019-2020
