Shoddy renovation­s to blame in high quake toll

-

ROME, ITALY — Shoddy, pricecutti­ng renovation­s, in breach of local building regulation­s, could be partly to blame for the high death toll from this week’s devastatin­g earthquake in central Italy, according to a prosecutor investigat­ing the disaster.

As questions mount over the deaths of nearly 300 people, prosecutor Giuseppe Saieva indicated that property owners who commission­ed suspected sub- standard work could be held responsibl­e for contributi­ng to the quake’s deadly impact.

Mr. Saieva, who works in the Rieti region between Rome and the quake’s epicenter, said the tragedy could not simply be filed away as an unavoidabl­e natural disaster.

“If the buildings had been constructe­d as they are in Japan they wouldn’t have collapsed,” he told La Repubblica.

Within hours of the quake hitting on Wednesday, Mr. Saieva was in Amatrice, the small mountain town hit hardest by the quake.

He’s inspecting the damage there before opening a preliminar­y investigat­ion for possible culpable homicide and causing a disaster.

The crushed partition walls of a collapsed three- storey villa were among the sights that caught his eye. “I can only think it was built on the cheap with more sand than cement,” he said.

A number of engineerin­g and architectu­ral experts have highlighte­d the widespread use of relatively cheap cement beams for house extensions and renovation­s as a possible factor explaining why so many buildings collapsed.

Heavy and inflexible, the cement beams become deadly if released by shaking because they will crush older walls beneath them with deadly implicatio­ns.

“If it emerges that individual­s cut corners, they will be pursued and those that have made mistakes will pay a price,” the prosecutor said.

CENTURIES-OLD PROBLEM

The issue of whether some of the deaths could have been avoided is particular­ly acute in the Amatrice area because it is so close ( 50 kilometers, 32 miles) to L’Aquila, which was hit by a 2009 earthquake in which over 300 people perished.

An outcry over the shoddy, corrupt building practices which led to so many buildings in the university city being inadequate­ly prepared for a quake led to the national Civil Protection agency making almost €1 billion ($1.2 billion) available for upgrading buildings in quake-vulnerable areas.

But the take-up of grants has been low. Critics blame bureaucrac­y but others maintain that independen­t- minded villagers will always find the cheapest way of getting their renovation­s done, whatever the risks.

Some 40% of the Italian population, 24 million people, live in zones vulnerable to earthquake­s and the risk that entails has been a subject for the country’s finest minds for centuries.

As early as the first century, an advisor to the emperor Vespasian, Pliny the elder, was making recommenda­tions on how buildings could be designed to withstand tremors.

And the thicker walls and stone piers that are features of many modern- day quake- proof buildings, were also included in plans drawn up by Renaissanc­e architect Pirro Ligorio in the late 16th century, after southern Italy was devastated by an earthquake that caused 2,000 deaths.

HUGE BILL

Experts, however, say protecting Italy’s unrivalled artistic and architectu­ral heritage is far from straightfo­rward.

“If we start from the idea of upgrading every old building to comparable safety levels of a modern building built to anti-seismic norms, we have to accept that we will never get there,” said Paolo Bazzurro, a professor in constructi­on techniques at the University of Pavia.

The trend away from traditiona­l wooden roofs and beams is not the only problem: widening window openings and the removal of reinforcin­g chains embedded in walls have also contribute­d.

“These things make buildings more vulnerable,” said Mr. Bazzurro.

Prime Minister Matteo Renzi has promised to rebuild the hilltop villages devastated by the quake. There will be no repeat of a failed attempt to replace the old communitie­s with new towns elsewhere, which happened after L’Aquila.

“There are lots of technicall­y feasible things that can be done and do not require huge interventi­ons,” said Culture Ministry expert Paolo Iannelli.

“Given that towns in the seismic areas have acquired a knowledge of what works over the centuries and generally used the most appropriat­e materials, it is a question of correcting renovation­s that have been done over time and have impacted on the resistance of the buildings,” he told AFP.

Better and more regular checks on the impact of rain on foundation­s would be one area where the state could improve its controls, he added.

For houses built before anti-seismic measures became the norm in 1970, it is relatively easy to install shock absorbers, experts say.

But a comprehens­ive solution will not come cheap. Infrastruc­ture Minister Graziano Delrio was asked last week how much it would cost to bring every building in Italy up to modern anti-quake standards. His answer: €360 billion. —
