All sides in the Millennium Tower debacle appear to be nearing an agreement on a $100 million-plus fix to stop the 58-story high-rise from sinking further [...]
The latest plan calls for drilling piles into bedrock from the sidewalk on the building’s southwest corner. The proposal would be less extensive and intrusive than the plan floated in April, which called for drilling as many as 300 micro-piles to bedrock through the building’s concrete foundation.

A large crack formed in a window at the sinking and tilting Millennium Tower over the Labor Day weekend, prompting officials there to block off part of the sidewalk on Mission Street as a precaution, NBC Bay Area’s Investigative Unit has learned. City inspectors issued a notice of violation on Tuesday, giving the Millennium management 72 hours to report back on the extent of the problem and the soundness of the building’s façade in light of the failure. — nbcbayarea.com

Soon after the incident a resident living on the 36th floor found a crack in his window. The high rise is... View full entry
In a city where a tilting 58-story tower has attracted international attention, the construction of big buildings now is scrutinized for any sign that a newcomer might be causing structural damage to its neighbors.
Which is why a full investigation was launched this winter after an anonymous complaint that the excavations for a pair of new, extra-tall towers were harming the 18-story high-rise in between.
And the scrutiny is certain to continue [...].

"The building in question is 25 Jessie St., an 18-story tower from the early 1980s," reports the SF Chronicle, and so far the structure has only sunk less than an inch—far less than the infamous Millennium "Leaning" Tower just two blocks away that has sunk 17 inches and tilted 14 inches to the...

In a December 2016 assessment of the issue obtained by NBC Bay Area, Palo Alto-based building consultants Allana Buick & Bers Inc. trace the odors to openings between the building’s façade, or curtain wall, and the core structure.
The consultants point to the “excessive” settlement as a likely source of the issue, adding, “This condition may be more widespread than these two test areas and may be present in the entire stack. We recommend further investigation of this issue.”

Pamela Buttery lives on the 57th floor. To demonstrate how her home tilts slightly to the left, Buttery hits a golf ball straight ahead toward the window. [...]
The ball takes a sharp left turn toward the direction of the tilt, and it ends up in the northwest corner of her living room. [...]
How to fix the tower, or at least keep it from leaning even more?
Some solutions include pouring a concrete collar around the foundation or building a buttress.

In a highly unusual case of urbanism, the whole town centre and its surrounding neighbourhoods are to be demolished...The 3,050 homes that would be affected by the impact of the mining – in addition to shops, offices, schools, the city hall and the hospital – will all be bought by [the LKAB mining company], knocked down and relocated. The process of moving the city will happen in phases, with the majority estimated to be completed by 2040. — The Guardian

The Guardian gives an overview on how locals are reacting to... View full entry
New studies are showing that Chinese cities are slowly sinking as a result of rapid development and excess groundwater use. According to reports, as many as 50 cities across the country are affected by soil subsidence, including the country’s largest - Shanghai. Apparently, Shanghai has been slowly sinking for at least 90 years. — inhabitat.com
