The seismic improvement project carried out by Cobar consisted of a series of local repair works aimed at achieving overall building stability (tie-rods, floor slabs, connectors, roof kerbs), eliminating the thrusts from the vaults and arches (tie-rods, floor slabs, roof kerbs), eliminating ruins and structural collapses caused by the earthquake (attic consolidation/rebuilding, roof rebuilding), eliminating critical points (sheet vaults and stud elements).

The entirety of the roof has been completely rebuild, since the earthquake had caused part of the thrusts that triggered the crumbling of some of the facades.

Part of the roofing, namely the angle connections, rested on wooden struts that have contributed to the rotation of the facade walls. These rotations have resulted in local collapses and substantial rainwater ingress, which have been remedied via the reconstruction of the roof: it is based on a wooden structure that mimics the original structure, while eliminating thrusts, in alignment with the necessary struts, through kerbs and/or metallic tie-rods. Reinforced masonry material has been used to build these kerbs. The floors, on the other hand, have been reinforced and strengthened with a lightweight concrete slab, the purpose of which is to secure the building  on the horizontal plane and transfer all forces that exert an orthogonal stress on each wall to the walls parallel to the direction of the earthquake. Reinforced connectors between slabs and masonry walls and tie-rods were used for this purpose.
