INCOGA has carried out a unique structural intervention on a residential building, involving the longitudinal cutting of one of its side façades in order to widen the vehicle access to the plot.
The work involved replacing the existing 55 cm thick masonry wall, which formed the façade enclosure, with a new 20 cm thick reinforced concrete wall. The difference in thickness between the two served to widen the entrance ramp.
This work forms part of the renovation and refurbishment project for an old detached house, located in the centre of A Coruña, which is being carried out by INCOGA.
How was it done?
Firstly, an auxiliary metal stabilisation structure, consisting of a series of beams and columns, was installed on the inner face of the existing masonry wall. On the outside, metal profiles were fitted to connect the two structures, thereby ensuring the stability of the whole.
The existing wall was then demolished, from top to bottom and floor by floor.
Next, a reinforced concrete perimeter beam was constructed to secure the entire foundation. Reinforcement bars were left in place to connect to the footing of the new wall.
Subsequently, the footing for the new wall was constructed, connecting it to the reinforcement bars of the perimeter beam, which had previously been built on the inside.
Finally, once the new reinforced concrete wall had been constructed and connected to the structure of each floor, the original steel framework was removed.
