The sensors have been placed on building facades and ground level near Codinella and Galceran Andreu streets. These devices are essential for monitoring the impact of the 12-meter deep excavation, where 80% of the rock removal will be conducted using controlled explosives.

The 22 million euro project is currently experiencing administrative delays. The Directorate General of Energy, Mines and Industrial Safety has yet to authorize the preliminary seismic tests, pushing back the original March start date for the micro-blasting operations.

Technical inspections of approximately 68 nearby homes are also planned to document their current condition before work intensifies. Meanwhile, archaeological monitoring continues at the site, located near the old courts, though no significant historical remains have been discovered to date.
