"Strengthening heavily overestimated homes" | inside

Several experts point to Hans Alders, Reinforced National Coordinator Groningen (NCG). He has had thousands of homes inspected in recent years to see if earthquake reinforcement is needed. The NCG has assumed an earthquake risk at an extraction level that has already decreased by more than half in the meantime.

"The number of dwellings estimated to be dangerous was far too high, and the reinforcement plan was based on old knowledge," Professor Ira Helsloot said Wednesday in the House of Representatives. He states that scientific knowledge about the risk of earthquakes was already much further. "They did not find the best option possible, but they were very cautious, the same thing applies to the estimation of the strength of the houses." They thought again: "It should not not be ours when a house collapses. "

Also expert Raphaël Steenbergen from TNO has, after critical questions from the deputies, recognize that it is clear for a long time that the strengthening of homes has been exaggerated. "Personally, I have raised it several times, as this does not lead to a reasonable reinforcement task for Groninger. There were forces around us that stopped him in a certain way. "

Mine Condition Monitoring also breaks down noisy notes in an advisory report.The watchdog writes that the reinforcement recommendations are based on a production of 50 billion cubic meters.This has now been reduced by half. "Now that gas production is further reduced, the difference in approach will further increase. The end result is an overestimate of the number of buildings in Groningen that needs to be strengthened. "

Meanwhile, experts are taken seriously and no longer need 20,000 homes to strengthen, but only 1500. In addition , there are nearly six thousand residents who are offered a reinforcement because they fall into a "margin of uncertainty."

Bizar

MP VVD Yeşilgöz is shocked: "Weird. Experts and scientists confirm that the NCG has knowingly guessed the security risks of the people of Groningen on the basis of old conservative models and not on the basis of all the knowledge of today. "The liberal states that many of Groninger are needlessly dangerous felt and needlessly safe." What is even worse, is that scientists knew it but did not dare to report it for fear of repercussions. My mouth is open. "
