This hypermarket which is over 20.000 m2, expanded its sales area by more than 30% and more than doubled its storage capacity after the expansion made in 2011. Our company was responsible for conducting much of the works on the second phase of the project. This works included pavement, metal structures, drywall partitions, roofs, underground and overhead trunking, general building, plumbing, and electrical and telecommunications installations. All this works were held incorporating the additional difficulty factor of maintaining the facilities open to public at all time, so a lot of coordination with the store and high effectiveness in all of the works were required. The reduced amount of time for the execution of the works and the high quality required, supposed a challenge which our technicians and operators overcame with large dose of professionalism and effort.
