![]() ![]() Peskin says an independent set of eyes on the project is the best way forward. "I want that to be independently verified and fact-checked." I don't want to take that at face value," said Peskin. ![]() "The DBI has said in writing that the building is safe and inhabitable. "You know, at what point does the building go from safe to unsafe? I think that transparent process is much more meaningful and comfortable for the public than what we're currently seeing, which is no information." "Basic stuff like, have you figured it out?" said Storesund. Storesund says it's time for more transparency from the city's Department of Building Inspection. If things did go awry, it would be very catastrophic." But again, you know, this building is situated in a highly urbanized area. "I'm not sure that we're on the verge of structural collapse. "I don't know a lot about the nuances of the proposed mitigation fix, but I would say it definitely comes across as ambitious," said Storesund. When asked whether this had ever been done: "I don't know that it's been done with this level of visibility or maybe on this magnitude, but it's definitely a known engineering strategy," said Guglielmo.īut Rune Storesund, a geotechnical engineer and Executive Director of the UC Berkeley Center for Catastrophic Risk Management, is not so sure. Guglielmo says the current plan to drill 52 new piles down to bedrock on Mission and Fremont streets and then connect them to the building's foundation was vetted by an engineering design review team of top experts. "I would trust what is being communicated through the engineers, the review panel, the city, which is to say that there is no cause for alarm, that the building is still capable of withstanding code required loads." "I can say with confidence that the process and the integrity of the engineering review for this project was sound," said Emily Guglielmo, former president of the Structural Engineers Association of Northern California. "It would appear that for whatever reason, that fix may be exacerbating the rate of sinking and tilting, which by all accounts had slowed until this project was undertaken," said Peskin. The experts warned it would cause "further loss of groundwater, which is likely to cause more irreparable damage to the building's substructure." "The fact that there's been a big setback is, needless to say, very frustrating," said Peskin.īack then, the Board of Supervisors recruited two geotechnical engineers to review the proposed fix. ![]()
