Inmobiliaria Colonial

Inmobiliaria Colonial, a leading high-end real estate agency in the Euro Zone, needed to upgrade its premises in its own eight-story building to comply with fire safety regulations.


The main task was to build a 100,000-litre water tank, which had to be installed four floors underground due to the building particularities.

This was an extremely complex project that involved working with heavy machinery at great depths. Nevertheless, everything went to plan, and the work was completed on schedule.
