Lima metro Project

Description of social and environmental performance.

Problem detected:

One of the environmental aspects to which FCC Construcción pays most attention is the release of dust into the atmosphere since it may produce the detriment of air quality, effect on the health of individuals and ecosystems, and have a significant impact on the climate.

In the case of Lima Metro (Peru), repairing cracks in the paving slabs at stations has involved a process of cutting concrete. This process consist of applying a special treatment to the cracked material, a dry grinding process, which has the undesired effect of generating dust.

Solutions adopted:

To prevent dust emissions to the environment, generated along cutting concrete process, enclosures were designed using moistened raschel mesh. These structures were specifically placed depending on the direction of the wind to avoid the dispersion of particles and, therefore, reduce the impact on air quality.

This type of mesh is manufactured using high-density polyethylene (HDPE) woven at different densities and treated to resist contact with UV rays. Therefore, it is particularly easy to handle and useful as a measure of preventing the release of dust into the air.

Results:

We have verified that this method substantially reduces the release of dust particles into the atmosphere in the cutting area, as they are captured by the mesh around the enclosure.

As a result, the adverse impact on air quality has been reduced, improving the well-being and health of both operators on site and residents in the nearby area.
