An employee works on the tail of a Boeing Co. Dreamliner 787 plane on the production line at the company's final assembly facility in North Charleston, South Carolina. Boeing denied the allegations, calling them "inaccurate" and said it stood by the planes' safety. Salehpour is scheduled to appear along with another whistleblower who worked at Boeing, a former aviation official and an independent safety expert at a Senate hearing on Wednesday about aircraft safety called "Examining Boeing's Broken Safety Culture: Firsthand Accounts." Boeing last week declined to comment on those specific allegations, citing the FAA's ongoing whistleblower investigation, but said, "Retaliation is strictly prohibited at Boeing." The company is scheduled to report quarterly results on April 24, when it will face investor questions about aircraft safety, production rates and FAA oversight.

☆ Boeing defends its planes’ safety ahead of whistleblower hearing

New York CNN —Boeing on Monday scrambled to address safety and quality concerns about its planes ahead of a whistleblower hearing in the Senate on Wednesday. Salehpour is set to be the key witness at a Wednesday hearing of the Senate permanent subcommittee on investigations. That has sparked investigations and allegations that some Boeing employees felt reluctant to raise questions about the safety of the planes they are building or inspecting for fear of retaliation. The average 787 does 600 flights a year, according to Chisholm, and the tests Boeing put the planes through simulated 165,000 flights. Boeing and the Federal Aviation Administration have admitted that some of the planes did have problems with the gaps between parts of the fuselages that were wider than the standards set by Boeing.

☆ Bridge accidents: Three ships have hit bridges in Argentina, China and Baltimore in just three months
▼ + stars: | 2024-03-27 | by ( Jessie Yeung | ) edition.cnn.com time to read: +7 min

These events all happened within the first three months of this year – and all after collisions with large commercial ships. And a month earlier, a large cargo ship collided with the Zárate–Brazo Largo Bridges crossing the Prana River in Argentina, according to now-shuttered government-run news agency Télam – severely damaging the ship, though the bridge remained intact. By contrast, in the Baltimore example, the water channel and bridge are wide and tall enough to accommodate large vessels – and the cargo ship hit the bridge pier, not the bridge itself, Andrawes said. But even these measures can only do so much in the event of a large cargo ship collision, Mercogliano said, pointing to the Baltimore collapse. “And even when the ship hit those dolphins, the ship was so large it towered over them and actually struck the bridge itself.

The steel frame of the Francis Scott Key Bridge sits on top of the container ship Dali after the bridge collapsed on Tuesday. After the 1980 collision, he argued, more substantial dolphins or a fendering system should have been added to the Key Bridge. “You knock out one of the support posts, the entire bridge collapses.”The Key Bridge is hardly unique among large bridges in its age. Some other bridges that cross major shipping routes are designed with more extensive protections than the Key Bridge’s. In the wake of the Key Bridge collapse and with the rise of larger container ships, some experts said that engineers should reassess necessary bridge safety features.

It recently unveiled what it calls Vitruvius, an AI program that helps consumers design custom homes online and get the plans, making the process cheaper and faster. Vitruvius can recall every design and possibility it's ever seen, according to Ballard. Though other AI models have gotten into hot water for potential copyright infringement, Ballard said he isn't concerned in this case. "I have no doubt that tools like this are going to change the way that we do things." Ballard said the implications of AI in architecture extend beyond just consumers looking to save on architecture fees.

Kéré’s Berlin-based firm says the building’s top-heavy appearance was inspired by the palaver tree, which traditionally served as a meeting place. Designed for developer s2e Technologies by US architecture firm Gensler, the four circular residential structures can accommodate a combined 84 households. But it is perhaps Bjarke Ingels, founder of Danish design firm BIG, that has had the greatest impact on the city’s once modest skyline. The first restored sections are set to be ready in time for this summer’s Paris Olympics. Norwegian architecture firm Snøhetta and local practice Blight Rayner — who together beat more than 20 entries in an international competition — say that the design was inspired by the flow of the Brisbane River.

LOS ANGELES (AP) — Los Angeles motorists should expect traffic snarls during the Monday commute as crews assess how much damage was caused by a raging fire over the weekend that closed a major elevated interstate near downtown, officials said. Commuters were urged to work from home or take public transportation into downtown Los Angeles. Newsom declared a state of emergency Saturday afternoon and directed the state Department of Transportation to request assistance from the federal government. Los Angeles Mayor Karen Bass said she had also talked with U.S. Secretary of Transportation Pete Buttigieg about any additional resources that may be needed. California Secretary of Transportation Toks Omishakin said storage yards under highways are common statewide and across the country.

LOS ANGELES (AP) — Los Angeles motorists should expect traffic snarls indefinitely as crews assess how much damage was caused by a raging fire that closed a major elevated interstate near downtown, officials said Sunday. Commuters were urged to work from home or take public transportation into downtown Los Angeles. Newsom declared a state of emergency Saturday afternoon and directed the state Department of Transportation to request assistance from the federal government.

The lawsuit argued Select Structural Engineering didn't identify the risk of collapse, the danger of such a collapse and repairs that would have avoided a collapse. “At no time did Select Structural opine that the defects in the west wall would require an evacuation of the building,” the lawsuit said. In the email, Van De Wiele wrote, “He was frustrated and whispered to me that ‘the whole side is going to come down. '”Van De Wiele wrote that he told Haut he should tell supervisors Rich Oswald or Beth Bringolf. Since the building collapsed, residents have filed several lawsuits arguing that the building owner, engineering company and city officials were negligent.

☆ American Cities Have a Conversion Problem, and It’s Not Just Offices

There is an aging office building on Water Street in Lower Manhattan where it would make all the sense in the world to create apartments. The 31-story building, once the headquarters of A.I.G., has windows all around and a shape suited to extra corner units. Right across the street, one office not so different from this one has already been turned into housing, and another is on the way. But 175 Water Street has a hitch: Offices in the financial district are spared some zoning rules that make conversion hard — so long as they were built before 1977. But that idea died in the State Legislature this spring, along with the rest of the governor’s housing agenda.

[1/3] Mexico City's Mayor Claudia Sheinbaum speaks near Mexico's President Andres Manuel Lopez Obrador (not pictured) during a news conference at the Old City Hall (Antiguo Palacio del Ayuntamiento), in Mexico City, Mexico January 20, 2023. "If accidents continue, like a cable or the signal system breaks, the National Guard is not going to detect that or make a difference," Miranda said. A school collapse that killed 19 children in a 2017 earthquake happened on her watch as a district mayor of Mexico City. She filed a criminal complaint accusing two prior attorneys for the district of failing to enforce the law after discovering illegal construction, and became Mexico City Mayor in 2018. Now, Lopez Obrador has backed her decision to use the National Guard, in a clear sign of support for her.

CNN —If you look out onto the Dubai skyline, you’re likely to be admiring the work of Yahya Jan. Due for completion in 2023, the Ciel Tower will have more than 1,000 rooms and suites spread over 82 floors – and at around 1,200 feet (365 meters) high, it is set to become the world’s tallest hotel. A passion projectFor the project, Jan was tasked with designing the skyscraper on a triangular plot of land at Dubai Marina with an area of just 2,500 square meters – small for a building of that height. A rendering of Ciel Tower at night. “When you design a project as complex as the Ciel, you can never let your guard down, you can never say it’s over,” he said.
