(It's the NYT but honestly there is little SF coverage, and Curbed doesn't seem to be an authority on building structures either )
Hanson Tom, the city’s principal engineer, said that at the time Millennium Tower was being constructed the developers had not agreed to a review by outside experts on the soil conditions or the foundations of the building and that the city had no laws to compel them to conduct these reviews.
The city was not prepared to assess the structural integrity of the Millennium Tower because it was one of the first skyscrapers erected in the business district, officials said.
“We didn’t have anything in place from a regulatory perspective on how to deal with buildings of this nature,” said Ronald Tom, the deputy director of the city’s department of building inspection.
The city now relies on outside experts to verify the structural integrity of proposed skyscrapers because they do not have the technology to verify the computer models used by developers.
But the hearing on Thursday did not clarify why city officials had declared the building safe for occupancy despite the problems with the foundation. Aaron Peskin, the San Francisco supervisor who called Thursday’s hearing, said the inquiry would continue in the coming weeks.
The tilting tower has produced introspection among engineers in part because when the building was completed the developers received at least nine awards for “excellence in structural engineering,” among other citations.
Gosh, the engineers have lost their credibility..Maybe they should consult the pros in Japan at Obayashi... Where are the experts???
