Ever since its opening in 2009 the Millennium Tower has been slowly sinking, so far it's settled about 16 inches on its southwestern corner, causing the entire to tilt around 14 inches. Residents applied for a permit to perform a retrofit back in December 2018 and a plan is now in place to... View full entry
With earthquakes in the news following a pair of recent tremors in California, it’s important to remember that seismic design is an integral and increasingly complex aspect of building design architects work hard to address. An ever-improving standard, seismic codes not only save lives, but also... View full entry
Before launching the Mola Structural Kit 1 in 2014, Brazilian architect Márcio Sequeira spent ten years developing the Molar design model before it hit the market. He initially came up with the Mola Structural Model while he was a postgraduate student in architecture school. Since then, Mola has... View full entry
Eight months after the discovery of cracked steel girders forced its closure, the Transbay transit center is safe to reopen, an independent panel of engineers and experts has concluded. The reopening is set for 6 a.m. July 1. — San Francisco Chronicle
A five-member peer-review committee appointed by the Metropolitan Transportation Commission has approved a series of recently-completed structural repairs made to the Pelli Clarke Pelli-designed Transbay Transit Center in San Francisco.

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
The latest safety concern over San Francisco's sinking Millennium Tower occurred Labor Day weekend when residents heard creaking sounds followed by a loud popping noise in the building. Soon after the incident a resident living on the 36th floor found a crack in his window. The high rise is... View full entry
The Hill House in Helensburgh was built as "a home for the future" by Charles Rennie Mackintosh in 1902. But the experimental building material used has allowed water to soak into the building. Now, the National Trust for Scotland will surround the house with a protective "shield" in the form of a "giant cage" while it comes up with ways to restore it. The trust plans to build the huge see-through structure [...] over the top of the landmark to protect the building from the elements. — bbc.com
This temporary structure buys preservationists time in finding a permanent solution to the building's structural problem. While the design problem persists, architects Carmody and Groarke have allowed a unique opportunity for visitors to experience the landmark building from new perspectives with... View full entry
“The Structure of Design: An Engineer's Extraordinary Life in Architecture” examines the long career of Leslie Earl Robertson, one of the most celebrated structural engineers in modern architecture. Thanks to publisher The Monacelli Press, Archinect is giving away five copies of the book to... View full entry
Over thousands of years, the building science of timber framing developed independently in both Northern Europe and China. But one big difference between the regions is that China, by virtue of its size and geological traits, is prone to devastating earthquakes. Ancient Chinese builders thus needed a way to create wooden structures that could not be shaken apart, and that were not so stiff that its support members would shatter. — Core 77
Known as dougong, these earthquake-resistant series of brackets were designed and engineered roughly 500 B.C. When interlocked together, the joints transfer weight to supporting columns, containing so many redundancies they can not be shaken apart. By spreading their tolerances over multiple...

How can architects determine if their designs are structurally sound? Aside from consulting with a professional structural engineering firm, the Mola Structural Kit offers a playful way to test out the strength and durability of various designs. The company has unveiled the second edition of the... View full entry
The pedestal extends 42 feet beyond the building’s core to the north and south. The south overhang will suspend the tower over three parallel Long Island Rail Road tracks. The north overhang will act as a counterbalance....Rather than hide the unusual support system, Brookfield will highlight it with a cladding of travertine quarried about 15 miles east of Siena, Italy. — NYT

Now after escalating complaints, New York City transportation officials said on Monday that something would finally be done to solve the riddle of what they call “Times Square in the Sky.”...That something — if the crossing can take it — could be building a new path to alleviate congestion
But...any expansion of the promenade would most likely be complicated. “I have to tell you, every time we touch this 133-year-old bridge, it tends to be costly and complex.”
