Emergency services in Vitoria-Gasteiz deployed a large security operation last Friday on Paraguay street due to the imminent threat of a structural element falling from a great height, in an intervention that lasted over ten hours.

The incident, which began at 11:19 AM, required cordoning off a 50-meter area to ensure pedestrian safety. The alert received by the Fire and Rescue Service warned about a brick panel, approximately 1.5 meters high, located between the roof and the seventh floor of a building.
After an initial inspection, firefighters confirmed that the wall had opened at the expansion joint, showing a gap 6 meters wide and a separation of about 20 centimeters from the original facade. Given the dangerous situation and the imminent risk of collapse, a 10-meter protective passage was initially established.
However, after a technical assessment with the articulated arm, it was determined that a direct intervention could destabilize other parts of the facade. Therefore, the security perimeter was extended to 50 meters, with the support of the Local Police to remove vehicles and containers from the affected area.
Finally, after securing the surroundings, the Local Police maintained surveillance of the site while technicians from the responsible company managed the controlled demolition of the affected wall to definitively eliminate the danger. The firefighters' intervention concluded at 9:26 PM, after more than ten hours of operation.
The detachment of the brick panel is due to common constructive pathologies in buildings of a certain age. According to the standards of the Technical Building Code (CTE) and the pathology manuals of the Official College of Basque-Navarre Architects (COAVN), the main cause is usually thermal expansion. Ceramic materials expand with heat and contract with cold; if the expansion joint is obstructed or has lost its elasticity, the wall "pushes" outwards due to lack of movement space, causing the facade to separate.
Other technical factors explaining these events include the fatigue of the anchors (ties) that hold the brick to the structure and moisture infiltrations. The Alava climate is prone to intense rainfall, so water entering the joint can oxidize the metallic fastening elements, weakening the integrity of the enclosure until the 6-meter wide opening detected by the firefighters occurs.
