The stress-relief method proved to be an effective tool in the strength evaluation of distressed structures. Nothing in the 2018 assessment presented to the board had suggested that the building was at risk of collapse, she said, and the boards deliberative approach to doing necessary repairs had been based on the assumption that there was time to do it right.
