The Land Of Supertall Structures Has A New Record-Setter: The World's Largest Picture Frame

“It is quite an unusual structure, and in many ways, it's more like building a bridge.”
—Richard Browne, Al Rostamani Pegel, to Construction Week
No matter how you view it, the world's largest picture frame provides a whole new perspective of Dubai, United Arab Emirates. The city-sponsored Dubai Frame project represents where Dubai has been and where it's going.
The gold-plated structure—150 meters (492 feet) high and 93 meters (305 feet) wide—frames Dubai's older, historic city to the north, while the other side frames its modern skyscrapers to the south. There's an internal link as well. On the ground floor, an interactive museum captures Dubai's past, present and future. And at the top, there's a viewing gallery with a glass-bottom floor.
To support the 800-ton viewing gallery, each tower had to be level within a 15-millimeter (.6-inch) variance, according to Construction Week. So the team performed alignment checks on both towers after each of the 46 floors were completed. ARP rose to the occasion—the towers were completed within an 8-millimeter (.3-inch) variance.
“If you can get a concrete tower up at 150 meters with an 8-millimeter difference, then I think it's fair to say [you've done] pretty well,” Richard Browne, operations manager, Al Rostamani Pegel (ARP), the main contractor, told Construction Week.
It took 48 hours to lift the bridge onto the two towers.
PMI research shows project teams that draw from an array of perspectives and skillsets deliver powerful outcomes.
