Five Decades of Innovation

In recognition of its founding in 1969, the Council on Tall Buildings and Urban Habitat (CTBUH) has spent 2019 looking at the past five decades of skyscraper construction and development, as well as imagining what the next five decades might bring — hence, its 50th anniversary theme, “50 Forward | 50 Back.” The celebration will come to a head at the end of this month with the CTBUH 10th World Congress in Chicago. As in previous events, the congress will feature workshops, presentations, panel discussions and a symposium. The special focus, however, will be “The 50 Most Influential Tall Buildings of the Last 50 Years,” a global roster of landmark structures that, each in its own way, “represented a significant change in thinking or technique” from what came before. The list includes 1969’s 875 North Michigan Avenue (the former John Hancock Center) in Chicago; the Lotte World Tower in Seoul (2017) and the Burj Khalifa (2010), Dubai’s awe-inspiring megatall. Whether it was construction technique, environmental friendliness or outside-the-box architectural design, each building on the list had a notable role in advancing the art and science of the skyscraper, one of humankind’s most iconic creations.

CTBUH is expecting more than 1,500 delegates from at least 45 countries to attend the congress, which opens on October 28. An online registration portal will be open until October 18, so there’s still time to sign up. For more information or to register, visit the CTBUH website’s 2019 program page.

Otis Elevators in Empire State Building Get Their Due in New Exhibit

On July 29, visitors to the world-famous Empire State Building in NYC have the opportunity to embark on a “journey from the building’s construction to its place in pop culture today.” For elevator (and history, design and technology) enthusiasts, that journey includes a brand-new Otis display, which Otis states “showcases our rich history with this iconic building, as well as our latest technology that transports more than 10 million people each year . . . .” A few years ago, Otis won a hotly competitive contract to modernize the 68-elevator system, a job that included restoration of the Art Deco elevator lobby. At the time, it was the biggest elevator modernization in Otis’ 158-year history. Available with the purchase of a ticket to the Empire State Building’s 86th-floor observatory, the Otis elevator display allows guests to walk through a simulation of an elevator shaft. The display showcases not only how the original elevators operated, but the new technology installed. The new 2nd Floor Exhibits also include vivid, action-packed looks at the site in the 1920s, construction of the buildings, major tenant spaces, most famous celebrity visitors (with signed memorabilia) and, of course, King Kong!! If you’re in NYC, be sure to check it out.

Cat Caper in the Underground

A lost mother cat found a hideaway she thought would be a safe place to give birth but, according to the Daily Mail, workers at a London underground station who found the mom and her new litter had to act fast to get them out of harm’s way. It seems mama made her “birthing suite” underneath a new escalator unit that was only hours away from a test run.

The unit is in the Moorgate station, one of London’s busiest tube stations, which has been undergoing a renovation and expansion to service the Crossrail Elizabeth Line. The workers got in touch with the Royal Society for the Prevention of Cruelty to Animals (RSPCA), and animal welfare officer Siobhan Trinnaman responded to the scene. When she arrived, she found the four kittens in the escalator pit, but the mom was nowhere to be seen. “It’s very dangerous for cats, as it’s where the mechanism is to run the escalator,” said Trinnaman. With the escalator test scheduled for 6 p.m. that evening, Trinnaman had to act fast.

“They (the workers) were very concerned that if [the cats] remained there and the escalator was running, they would be injured or killed,” said Trinnaman. “I found the four tiny kittens and moved them to safety before setting a trap for the mum.” After a few hours, the mother was captured and reunited with her babies at the RSPCA’s local facility. The kittens, one girl and three boys, have been named after Tube stations. They are called Bow, Colin, Dale and Earl, after Bow Road, Collindale and Earl’s Court. The staff called the mom “Elizabeth,” after the Elizabeth line. They are trying to locate the owner, because the cat was wearing a collar, though she had no microchip.
