New problem at San Francisco's still-sinking Millennium Tower means it may be forever tilting


The seemingly unending saga of San Francisco's lopsided luxury skyscraper, the Millennium Tower, may have hit another wall this week, literally.

An underground shoring wall buried deep in the SoMa soil is threatening to hinder the $100 million dollar effort to right the sinking property, marking the latest problem in the beleaguered fix on the tower. That fix, termed the perimeter pile upgrade (PPU), began work last year.

The PPU seeks to halt sinking on the north and west sides of the building through the installation of piles into the bedrock, and subsequently shift weight toward the opposite corner and eventually reverse the tilt, now measured at a significant 28 inches, reported NBC News.

But the presence of a 3-foot-thick, 90-foot-tall steel and cement underground wall — installed as part of an earth retention system during the original tower build to enable construction of the five-story-deep parking garage next door —  may scupper that plan, according to experts.

“It just creates a huge amount more uncertainty about how it will respond when you implement the PPU fix,” deep foundation expert David Williams told NBC. “There are a lot of concerns that it may be hung up on that shoring wall.”

In 2019, chief engineer Ronald Hamburger of engineering firm Simpson Gumpertz & Heger, which is leading the work, said that the reverse tilting required to level the building will not be hindered by the wall, and that as the weight shifted to the east, the entire wall would sink into the clay.



Hamburger told SFGATE via email on Tuesday that the shoring wall is no surprise. "We have been aware of this wall’s presence since our earliest project involvement in 2014," he said.

He added that analysis of the foundation showed that "within about a year of completion of the upgrade project, the northwest building corner will recover about 1-1/2 inches of the past settlement," and that the building should recover around 3 or 4 inches on the north and west sides and continue to level out in "small amounts" over the next 40 years.

Hamburger also contested NBC's reporting that the building is currently at a 28-inch tilt. "Presently, the building tilts about 25-1/2 inches to the west and 8-1/2 inches to the north, as measured at the roof," Hamburger said via email.

"Almost certainly he is wrong — no one knows what will actually happen," Bay Area geotechnical engineer Bob Pyke said of Hamburger's 2019 assessment, via email, "He was, as usual, guilty of wishful thinking rather than carefully looking into the details."

Pyke, who is not associated with the Millennium Tower project, said he believes it's time that someone else should step in. "But his ego and the firm’s potential liability will not allow that. He has to keep on bluffing," Pyke said. "The [San Francisco Department of Building Inspection] should withdraw the permit and put him/them out of their misery."

While maintaining that the tower is safe, Hamburger did voice some urgency regarding the fix earlier this year, telling the SF Government Audit and Oversight Committee, “Although the building remains safe, we believe the project needs to resume construction and complete this construction quickly.”

The PPU has been blighted by problems since work commenced in 2021.

The $100 million fix involved installing 52 piles 250 feet deep into the bedrock along the sinking north and west sides of the luxury building. But in September 2021 work was abruptly halted after the tower sank another inch over a matter of weeks due to the construction causing an "unintentional removal of excess soil as the piles were installed," a letter from Hamburger to the homeowners revealed. Some experts said the pause in work came months too late.

"That moratorium has been effective in halting the construction-related settlement and tilting," Hamburger told SFGATE at the time. "We are presently working to develop modified construction methods so that construction can safely proceed."

When an engineering report revealed that the pause in construction also stopped any further sinking, the Department of Building Inspection pleaded with the engineers not to restart work. "In the interest of all involved, please refrain from resuming construction," DBI's interim director wrote in a letter to the tower's general manager.

Then in January 2022, a revised plan, with a drastically reduced scope, was landed on. The new fix involves a big reduction in the number of piles to be installed into the shifting soil at 301 Mission — 18 to 24 new piles were to be installed, as opposed to the initial plan for 52.

The fix, according to Hamburger, was a voluntary retrofit intended to speed the settling along and bring an end to what has now been 7 years of uncertainty — and diminishing property values — for residents. An estimated condo value for one 1,246-square-foot unit in the building peaked at $2 million in 2016 before the sinking was reported; today one 1,517-square-foot unit is on the market for $1.35 million, and has already taken a price cut, as some refer to the building as the "Leaning Tower of Soma."

The tower's woes date back to 2016, seven years after its construction, when the tilting was first reported to the shock of residents. This led to a blame game and years of lawsuits, as the tower continued to sink toward the Mission and Fremont intersection.

Hamburger and Simpson Gumpertz & Heger were approved to lead the fix in 2018.

SF Millennium Tower Tilts Quarter Inch in Four Days


Newly released monitoring data shows that San Francisco’s Millennium Tower tilted a quarter inch during the four days it took to install the first test pile to bedrock last month.

The monitoring data tracks settlement, tilting and water pressure levels underneath the sinking and leaning structure since work began on a fix for the troubled tower in May. Since work began to shore the sinking structure up on the north and west sides, the building has settled nearly 2 inches at the northwest corner and is now tilting more than two feet at that edge.

The latest data – including the four days that the test pile was installed from Nov. 15 to Nov. 19 – shows a quarter inch of new tilt, as well as a tenth of an inch of settlement at the time the test installation occurred. At the same time, there was marked fluctuation of water pressure below the foundation on the Mission Street side of the structure.

The water pressure level was recorded at various depths more than 100 feet below the structure, where a layer of clay resides.

Veteran geotechnical engineer Bob Pyke said the sudden fluctuation is a telltale sign.

“This is a large drop -- you can't see the scale on this plot -- but this is a pretty dramatic effect” he said, pointing to the monitoring data chart that tracks the water pressure levels more than 100 feet below the building.  While the data shows plunging pressure level quickly came back up, Pyke said the brief loss would likely generate settlement.

Pyke suspects that the drilling method used to remove soil and water from the bottom of the hole is to blame.

“It's no different from sucking a straw into a milkshake,” Pyke said, noting that removal method involves using suction, essentially vacuuming up water and debris from the bottom of the shaft being drilled. He says the sucking process is likely stressing larger areas of the Old Bay Clay layer under the building’s existing foundation.

He noted that while the pressure recovered on the Mission Street side,  it did not return to previous levels under other parts of the foundation. Triggering accelerated settlement across other parts of the foundation of the building.

Other experts say the water pressure drop is evidence that the method designed to limit settlement may not be working as well as hoped.

“You can accidentally remove soil that you want to stay in place,” said Rune Storesund, a geotechnical engineer who runs UC Berkeley’s Center for Catastrophic Risk Management. He says the water pressure data suggests engineers could clearly do more to refine their methods. “You’re always going to get settlement, obviously you want that to be as low as possible.”

Still, Ron Hamburger, the fix designer, recently assured city officials that the settlement that has occurred during testing of new methods designed to limit sinking is within expected levels. Hamburger now has city permission to install two more test piles. Hamburger told city officials the additional testing is needed to help determine just how many piles will ultimately be used to shore up the structure.

New Tilting Prompts Revamp of San Francisco's Millennium Tower Fix


“There's no question that the fix has made things worse,” said Bob Pyke, a veteran geotechnical engineer who has advised Caltrans and federal agencies on large construction projects. He said that tilting was the side-effect of the digging needed to erect the planned underground shoring wall on the west side of the foundation. Like the digging last year to install foundation piles to bedrock, any disturbance from construction can displace dirt that had been acting as a buttress against the tower’s foundation, Pyke says.

“This ground loss simply allows the building to push outward in the westerly direction where they're working along Fremont Street,” he said. “It's similar to but a different mechanism in detail from what caused the settlement during the installation of the casings in the piles.”

San Francisco building officials say they have been consulted on the changes, but stress that Millennium engineers are solely responsible for the outcome.

As it stands, with the additional tilting since work on the underground wall along Fremont started in May, the tower is now leaning at least 29 inches at the top at the northwest corner.

That leaves a shrinking margin for error, given Hamburger’s caution that the tower’s safety systems -- like elevators and sewage lines --  could stop working should the tower lean 40 inches or more.

Should just call it a loss at this point.

The building officials aren't responsible for fixing this mess.

Tear it down and start the lawsuit process.

Two years after Surfside collapse, a bitter feud over the oceanfront land
by Tim Craig

SURFSIDE, Fla. — On a lot scarred by the memories of 98 people who died here two years ago, developers are hopeful a new luxury oceanfront 12-story condominium building could soon rise.

The building, designed by a world-renowned architectural firm, will be constructed of glass fiber reinforced concrete and was partially inspired by one of South Florida’s most recognizable skyscrapers. As described by Dubai-based developer DAMAC International, 57 homeowners will live in a building that includes “soft, cloud-like elements” and a “facade that echo[es] the colors and textures of sand” as its stands over a pristine beach.

But as the replacement for the Champlain Towers South condominium building progresses, the project is caught up in an bitterly personal debate over whether the 1.8-acre lot should also include space for a memorial to those killed in one of the nation’s most horrific building failures. Nearly two years ago, the condo collapsed as most residents were asleep in their beds, leading to an anguishing search-and-recovery mission and, eventually, the demolition of what was left standing.

To family members who believe tiny remnants of their loved ones could still be lying undetected in crevices around the site, as well as in the ocean breezes that sweep across it each day, the proposal for a new building is the latest insult in a flawed and rushed redevelopment project.

To truly honor the dead, they say, the millionaires who will call the building home should have to share the high-priced strip of land with those who never got a chance to leave the location on June 24, 2021.

“I lost my sister and my brother-in-law, and we received just 1 percent of my brother-in-law and 33 percent of my sister,” said Martin Langesfeld, who was referring to his sister, Nicole Langesfeld, and her husband, Luis Sadovnic. “We can work together and incorporate a memorial on the site, and they can still build their ultra-luxurious apartments. But we don’t build over dead bodies in America.”

The emotional debate, which includes some family members of the victims of the 9/11 terrorist attack on the World Trade Center in New York, is now dominating town meetings here in Surfside while serving as yet another test of how the nation recognizes grief and memorializes victims of tragedies.

From mass shooting scenes and the locations of deadly natural disasters, to newly discovered, centuries-old cemeteries, the question of what should come next has been vexing officials and developers for generations. Although some locations of mass death are ultimately preserved as memorials or historical markings, others have been rebuilt or repurposed as land values soar and communities seek ways to move beyond grief.

Shlomo Danzinger, the mayor of Surfside, said the city does not own the lot of Champlain Towers South and cannot dictate how it will be rebuilt. He also notes that Surfside is planning to build a permanent memorial to the victims of the collapse, on part of a public street that lies just a few yards from the footprint of the old building.

“You keep asking for something we can’t provide,” Danzinger told Langesfeld and other speakers who showed up at a town commission meeting on June 13 to protest the plans. “It’s not our property. … We cannot get you on the property.”

The developer, for its part, contends the new building will “add meaningful value to the beachside haven that is Surfside — and indeed, all of Miami.”

“We know we can never replace what was so painfully lost in Surfside and no single entity can ever do justice to a community’s memory,” said Niall Mc Loughlin, senior vice president of communications for DAMAC.

Within six months of the building’s collapse, the debris was cleaned up and transferred to a vacant lot in a western Miami suburb, even as the medical examiner continued identifying remains of the victims. Today, the footprint of the building includes the stub of former support beams and the buzz of water pumps that continually work to remove water from the site’s foundation.

As part of a $1.2 billion settlement to victims and survivors, the building’s lot was sold at auction last summer. There was only one bidder, DAMAC, which purchased the land for $120 million.

DAMAC hired Zaha Hadid Architects, a British firm founded by the late Zaha Hadid, to design the new condominium building on the site. Zaha Hadid, who died in 2016, had designed some of the world’s most breathtaking structures, including the 62-story One Thousand Museum residential building in downtown Miami.

Chris Lepine, director of Zaha Hadid Architects, conceded that the Champlain Towers South lot is “a charged site” but said his firm worked hard to “design the best possible” building to reflect its history.
“I think with such an important site, we do feel a responsibility to put in our best work, and our best efforts,” said Lepine, who added his firm and DAMAC strove to achieve “the best possible outcome architecturally for the site.”

Lepine said his firm has submitted two proposals for the property, mostly differing on setback and the vertical schemes. The units in the building will range from 4,000 to 12,000 square feet — easily making even the smallest residence a multimillion-dollar condominium in South Florida’s hot luxury-property market.

Lisa Shrem, 56, lost her best friend, Estelle Hedaya, who was 54, in the building collapse and now questions why she will not be able to visit with her on the site where she lost her life. Shrem said Hedaya and other victims’ “bones turned to dust” during the collapse, effectively turning it into a gravesite that should hold a memorial.

“It’s painful to see another building where people are going to live put on that site, for many, many reasons,” said Shrem, who added that just a few weeks ago Hedaya’s family received additional remains of her body from the Miami-Dade medical examiner’s office. “Plans for the new building are beautiful — it’s a beautiful building — but it just feels like it will erase everything that happened there.”

Monica Iken, who lost her husband on 9/11 and is the founder of September’s Mission, has joined Surfside family members in advocating for a memorial to be incorporated into the plans for the new condominium building. Iken noted family members of 9/11 victims also initially had to fight back against plans to build the National September 11 Memorial Museum in a location other than the footprint of the World Trade Center.

“The developer has 1.88 acres. You could give the families 0.44 acres for a memorial,” Iken said. “You could make it a garden space. We are not asking for a big memorial. We are just asking for a piece of land so you are not building over the dead souls that are there.”

The portion of the Champlain Towers South that collapsed, creating a mound of debris where most of the victims were found, roughly equals 0.44 acres. The Miami-Dade medical examiner’s office did not respond to a phone call seeking comment on whether any human remains could still theoretically be on the cleaned-up disaster site.

Mc Loughlin, from DAMAC, said the decision against putting a memorial on the site was effectively made by the judge who decided to auction the land as part of the settlement. The judge, Mc Loughlin added, “wanted the sale to benefit those who suffered the most.”

Throughout South Florida, news that a luxury condominium building will eventually be built on the site has prompted one nagging question: Who would want to live there?

Mc Loughlin said the company believes the project will attract “affluent families from around the USA and globally” including “entrepreneurs, celebrities, and other leading families from around the world.”

Carlos Marquez, a Miami real estate broker and agent, said he doubts DAMAC will have trouble finding buyers.

“Everything sells here,” said Marquez, who expects there could especially be interest from foreign buyers who have less knowledge about the Champlain Towers South disaster. “People often don’t know the history of what happened in some of these other [South Florida] buildings. … Yes, it will be sad for some people. But for other people, it will be a nice, beautiful building next to the beach.”

In Surfside, where Marquez said two-bedroom units at another luxury condominium next to the Champlain Towers South footprint are currently valued at about $1,600 per square foot, the debate over the location of the memorial is swept up in a larger political feud over Danzinger’s leadership and relationship with DAMAC.

Last October, during a trip to the Middle East as his son was beginning service in the Israel Defense Forces, Danzinger traveled to Dubai and met with DAMAC founder Hussain Sajwani. Some family members of the victims and the mayor’s political rivals, including former Surfside commissioner Eliana Salzhauer, have accused Danzinger of cozying up to the developer instead of fighting for the interests of the victims.

“The family members were totally disrespected,” said Salzhauer, who sat on the commission from 2020 to 2022. “They are trying to fast-track construction of this building. It is absolutely unacceptable because we still don’t even know why [Champlain Towers South] collapsed.”

Salzhauer added she is still waiting for the mayor to respond to months-old public records requests seeking more details of his trip.

The mayor, for his part, likens the interest in his trip to the “biggest political witch hunt in Surfside history.” He said he met with DAMAC simply to try to gauge whether there was any way they would give, or swap, land with Surfside so a memorial could be built on-site to try to meet the demands of family members. He said he quickly determined a land swap would be too complicated because the company needed to make a return on its investment in the property.

Danzinger added he paid for his own expenses while in Dubai, although he ate lunch at Sajwani’s house in Dubai. He said he doesn’t have to respond to information requests about matters that do not involve his use of city resources and rejected the idea that he was building a relationship with the developer at the cost of advocating for constituents.

“There is no partnership here other than what happens between a city and a developer who is going to be building here for five years,” he said.

DAMAC officials also say there was nothing untoward or unusual about the meeting.

Raysa Rodriguez, 61, narrowly survived the collapse and now feels as though she and other survivors and relatives of victims aren’t getting any say in what happens next. She blames both the rushed sale of the land and a lack of unity among those who lost loved ones in the collapse.

“Maybe if people would have stuck together, maybe we would be closer to getting a memorial,” she said. “There hasn’t been a cohesive group since Day One.”

To Langesfeld, who lost his sister and brother-in-law in the tower collapse, any debate about the memorial cannot be separated from a discussion about its location. When he visits the memorial, the 25-year-old said he deserves to stand where his only sibling took her last step.

“They didn’t die a couple feet away,” Langesfeld said. “They died where they are trying to develop this ultra-luxurious building. They didn’t die next door. … And that is the sole reason they can even develop on the site is because 98 people were killed overnight.”

Shrem agrees, saying she often visits her friend’s gravesite in East Brunswick, N.J. Yet, as she walks around the burial site, Shrem says, “it doesn’t feel that is truly where she is.”

“But when I go to Florida, I feel that is where Estelle is,” she said. “And when they put a new building over it … no matter how beautiful that view is, you are living on top of people who suffered an enormous tragedy.”

Like there was any doubt they would be building a high dollar megalith on top of that site?

Survivors were paid 1.2 billion, and the remains were trucked elsewhere...there are not bodies there or bones sticking out of the ground on the site. The whole thing is crazy but there is no chance that lot wold remain vacant.

I cannot believe the survivors and family members think they should have a say in what happens on the site.  You were compensated.  Move on.  If you can’t stand to drive by the site then don’t go there.  If you want to mourn your lost loved ones then light a candle or go to a house of worship.  The world is not going to be held hostage to your grief.  The truth is people die every day in lots of places and sad circumstances.  The world moves on. 

As for who would want to live there—lots of people want a beach front property.  Not everyone knows or cares that people died there… because people die everywhere.  I would have no problem living on that site.

I can’t believe you think your opinion about property and deaths that you have zero relation to matters…

 ::)

BUT you are correct, people die everyday in horrible ways. They don’t permanently close highways or the city of Chicago due to deaths.

I would hope the developer would create a small memorial out of respect but from the sounds of it most of the surviving family is older so in another 20 years no one remembers.

I am wary of the general idea of building a high rise structure on the beach front.  I like to hike down the Bolivar Peninsula now and then and I am astounded by the expensive housing just on the other side of the dunes.
