Incident Recap: Metro Construction Triggers Sinkhole
On July 7, a sinkhole occurred in the Putxet district of Barcelona, Spain. Investigations have directly linked the incident to the ongoing tunneling work for the Barcelona Metro’s L9 line. To ensure public safety, local authorities acted swiftly after the event, ordering the emergency evacuation of several residential buildings and commercial properties near the site.
Return Timeline: Most Families Must Wait Until Year-End
According to the latest announcement from the Government of Catalonia, the timeline for affected residents to return home varies. Residents of one less affected building are expected to be allowed back to their homes within the next 5 to 6 weeks. However, for three other buildings, involving approximately 18 families, the return date has been postponed until the end of this year due to a more severe safety risk assessment.
Technical Challenges: Foundation Reinforcement and TBM Restart
The delay in the return process is primarily due to both technical and safety considerations. Government officials explained that the foundation in the collapsed area must first be fully reinforced to ensure the structural stability of the buildings. Additionally, a Tunnel Boring Machine (TBM), used for the L9 line excavation and currently stopped underground due to the incident, must be safely restarted and moved. The completion of these two tasks is a prerequisite for the residents’ safe return.
Authorities’ Response: Streamlining Aid Applications
In response to the hardship faced by residents unable to return home for an extended period, the Catalan government has pledged to enhance support services for affected residents and businesses. Authorities have specifically highlighted that they will simplify the application process for advance payments of financial aid, aiming to provide more timely assistance to families facing financial pressure due to the delayed return.
