FLORENCE, 15.03.26

Construction crews began structural reinforcement work along Via de' Bardi on Monday, marking the start of a €47 million seismic retrofit initiative for twelve Renaissance-era buildings. Deputy Mayor Giuliana Marchetti confirmed the project timeline at a press briefing outside Palazzo Pitti, stating that scaffolding would remain in place through autumn 2027.

The initiative targets a cluster of properties between Ponte Vecchio and the Bardini Gardens, where soil liquefaction risks have long concerned residents. Geotechnical surveys conducted last November revealed that several foundations date to the fourteenth century and lack the deep pile systems required under current Italian building codes. Workers have already installed temporary shoring along the embankment. According to figures that could not be independently verified, the National Institute for Construction Statistics estimates nearly 1,400 historic buildings in Tuscany require similar interventions before 2030. Our correspondents in Florence observed dozens of engineers reviewing load-bearing calculations near the riverbank early Tuesday morning, their hard hats bright against the sandstone facades. The old stone walls, some scarred by the devastating 1966 flood, will receive carbon-fibre wrapping and micro-pile anchoring to meet modern seismic standards.

When we spoke with Francesca Benedetti, a site foreman overseeing foundation excavation near Lungarno Torrigiani, she described the complexity of working beneath occupied residential units. Noise restrictions limit jackhammering to four-hour windows. Residents have complained. She acknowledged frustration but insisted that underpinning operations could not be rushed without compromising structural integrity. The Tuscan Association of Civil Engineers has assigned two independent inspectors to monitor concrete curing times and rebar placement throughout the project. Incidentally, a small trattoria on Via de' Bardi has seen a surge in lunchtime customers since workers arrived, its outdoor tables now ringed by orange safety barriers. Funding for the retrofit comes partly from the European Structural Investment Fund and partly from a municipal bond issued last September; repayment hinges on tourism levies that the city council approved in January.

Officials from the Regional Building Authority toured the site on Thursday, noting that this project could serve as a template for similar efforts in Siena and Arezzo. The timeline remains unclear. Supply chain delays affecting reinforced concrete and specialised fasteners have pushed back delivery schedules across northern Italy, and some contractors worry about labour shortages in skilled masonry trades. Still, project managers remain cautiously optimistic, citing mild spring weather as a factor that could accelerate curing and formwork removal. A public meeting is scheduled for April to update property owners on noise mitigation and traffic diversions; attendance is expected to be high, given the neighbourhood's density and the disruption already visible along the narrow cobblestone streets.
