Rehabilitation of the façades of the Association of Engineers

Early 20th-century building with subsequent renovations and an upper floor extension added in the 1950s. It has three facades: Consell de Cent, where the entrance to the association is located; Méndez de Vigo Boulevard, with a Corinthian portico and staircase; and the rear facade.
The façade consists of solid brick surfaces, plastered with lime mortar, flat vault slabs, cornices, imposts, corbels, and eaves made of masonry covered with lime mortar.

The initial project involved general restoration. However, during the work, a second layer of stucco was found which was in danger of falling off along with repairs and severely deteriorated and poorly repaired slabs with large sections about to fall off. This led to a review of the initial project and the decision was made to demolish the slabs and rebuild them, completely removing the stucco and redoing it with lime mortar.
Once the balcony slabs had been demolished, formwork was used to incorporate a negative molding with the same relief, and a composite slab was created between the treated original joists and a new ring frame anchored to the facade and concreted on site. The final treatment was made with specific stuccos and was waterproofed and paved again. The works on the portico were the same, adding new beams and a new lower false ceiling.
A study was previously conducted on the sections requiring repair, using technical mortars and the respective specifications for each case, employing air lime, hydraulic lime, and fibers. The cracks were repaired using traditional methods, adding old bricks and reinforcing mortars.
The rest of the components, such as the folding doors and railings, have been cleaned, repaired, treated, and painted.
