Concerns raised over the sinking of prestigious Millennium Tower in San Francisco
There are grave concerns surrounding San Francisco’s Millennium Tower, which is now beginning to sink and lean considerably, highlighting serious faults in its construction.
Since its development in 2008, the 58 storey residential building, voted one of the most prestigious in the world, has now sunk 16 inches and is continuing to sink at a steady rate according to the San Francisco Chronicle.
There is uncertainty as to how the building issues will be restored, with Millennium Tower Officials laying the blame at Transbay Officials, believing the building’s foundations were disrupted through the excavation of the Transbay Terminal. This claim, however, has been refuted.
In a statement, the Transit Authority said: “Aware that the Millennium Tower foundation failed to reach bedrock and was therefore inadequate to support the Tower, the Transbay Joint Powers Authority took the extraordinary step of spending more than $58 million to install an underground buttress between the Millennium Tower and the Transit Center site before the TJPA began its excavation for the new Transit Center.”
They continued, “To cut costs, Millennium did not drill piles to bedrock” and “Had it done so, “the tower would not be tilting today.” The building is concrete based, lacking a steel-frame and is situated on an area of mud-fill.
The Millenium Tower’s Homeowners Association are currently looking at all legal options, fearing a substantial loss of investment.

Skanska invests $225m in Houston office project
Skanska is investing US$225m in an office development project, 1550 on the Green in Houston, with construction expected to begin in June and scheduled to be completed in 2024.
The construction contract is worth US$125M, which will be included in the Q2 order bookings. International law firm Norton Rose Fulbright has signed a 15-year lease for about 30 percent of the building.
Located at 1550 Lamar Street, adjacent to Discovery Green, in downtown Houston, Skanska plans to develop and build a 28-floor, 34,800 square meter office tower.
1550 on the Green will be the first part of a three-block master plan by Skanska, which will transform the parcels into a distinguished district known as Discovery West and consist of 3.5 acres of mixed-use development full of restaurants, retail and lush green space. The project will target LEED and WiredScore Platinum certifications.
Since 2009, Skanska has invested a total of US$2.8 billion in commercial and multi-family projects, creating more than 1 million square meters of sustainable and community focused developments in select U.S. markets. Skanska USA had sales of SEK66 billion in 2020 with 7,600 employees in its operations.
Skanska’s flagship London office has set the standard in sustainable workspaces by becoming the first in the UK to achieve WELL Platinum under the new v2 pilot scheme.
The accreditation from the International WELL Building Institute (IWBI) was awarded through the v2 pilot, the newest version of the WELL Building Standard. It looks at all building features and management processes – from air and water quality to lighting, acoustics, nutrition, thermal comfort and mental wellbeing. It’s widely recognised as the industry yardstick for measuring how workspaces can contribute to the wellbeing of occupants.
The offices – which span three floors of the newly developed 51 Moorgate – contain floor-to-ceiling windows for extensive natural light, dedicated wellbeing and quiet spaces, as well as stringent air and water quality monitoring, among a range of other features that have helped earn the standard.
The company has also been exploring drone flights for use in industrial environments.
Peter Cater, Development Manager, said it was invited to carry out trials because of its use and knowledge of drone capability. "The trials have benefited everyone involved: sees.ai get to test their equipment and remote use of the drones and we get access to accurate, real-time data on our construction activities which benefits us and our customer, the Defence Infrastructure Organisation."
“Projects like this – at the forefront of innovation – go to show what an exciting industry construction is to be involved in. We are always looking for innovative ways of working, ways to be more sustainable so we can find better solutions for our customers. These trials are just one small part of our digital transformation journey.”
