Link here. The builders literally included a 350 foot high waterfall that exits the skyscraper and falls down the building’s side.
A spokesperson for the property, Mr Cheng, told Kan Kan News that the main water source is from recycled tap water, rain water or from other channels. ‘Our building has a four-storey underground water storage and drainage system, from which the water is pumped and recycled,’ Mr Cheng said.
The electricity bill for just one hour of operation is a whopping 800 yuan (£89), he added. ‘That’s why we don’t switch on the waterfall every day – only for special festivities in the city,’ he said. And each time, the waterfall is set to run for only about 10 to 20 minutes to save electricity.
Architects for skyscrapers are getting increasingly creative. They have added trees, vines, greenery everywhere. A waterfall, however, is really clever, though I’m not sure how practical this will be, in the long run. Water falling that distance can do a lot of damage over time.
An evening pause: As noted on the youtube webpage, “The last two components of the Incity Tower spire were put in place by helicopter on Sunday 21 June . This metallic spire, which measures 50 metres and weighs 25.9 tonnes, took the building to its final height of 200 metres. This confirms its position as the highest tower in Lyon and the third highest in France. Three aerial beacons and a lightning rod will now be placed at the top.”
Very strange. They all look like something out of the weird Yugoslavian science fiction animated film community of the 1960s. Somewhere I’ve seen the one listed as #1 (though it isn’t the first in the story), though I can’t remember where.
A new Chinese suspension bridge, set to open November 25, has won top honors for being such a long three-tower/two span bridge.
When it opens on Nov. 25, Taizhou Bridge will carry six lanes of traffic (plus two maintenance lanes) nearly 3-km across the Yangtze River. Though the total length of 2,940 m is an awfully long way, the bridge has two main spans using three towers rather than the norm of one main span using two support towers.
The two spans are each 1,080 m (3,540 ft) long, which individually is less than the main span of the Golden Gate Bridge at 1,280 m (4,200 ft), and much less than the 1,990-m (12,830 ft) span of the Akashi Kaikyō Bridge, the longest main span of any suspension bridge on Earth. Two end spans of 390 m (1,280 ft) connect Taizhou Bridge with the banks of the river.
But in using two spans the Taizhou Bridge is a major breakthrough in structural engineering. The design requires the perfect balance of flexibility and rigidity in its 192-m (630-ft) steel central tower in order to withstand changing and imbalanced loads to either side. The complementary side towers are 178 m (584 ft) tall, and are made of concrete. The two main cables supporting the bridge are 3,110 m (10,200 ft) long and 72 cm (28 in) in diameter.
Think about it. The central tower is going to be pulled from both directions. Similarly, the outside towers must have incredible strain pulling them towards the center. Balancing it all is an amazing architectural achievement.
Maybe the building’s problem is that it has Al Gore as one of its tenants.
Seriously, the article illustrates well “the law of unintended consequences.” You pass a law or regulation intended to do x, and discover that people instead manipulate the law or regulation to get y instead.
“Bertha,” as it’s known, is the world’s largest TBM and will spend the next 14 months boring a 1.7 mile (2.7 km) tunnel under the city as part of a US$1.2 billion project to replace a viaduct damaged in a 2001 earthquake.
The secret to Roman concrete lies in its unique mineral formulation and production technique. As the researchers explain in a press release outlining their findings, “The Romans made concrete by mixing lime and volcanic rock. For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms. The seawater instantly triggered a hot chemical reaction. The lime was hydrated—incorporating water molecules into its structure—and reacted with the ash to cement the whole mixture together.”
The Portland cement formula crucially lacks the lyme and volcanic ash mixture. As a result, it doesn’t bind quite as well when compared with the Roman concrete, researchers found. It is this inferior binding property that explains why structures made of Portland cement tend to weaken and crack after a few decades of use, Jackson says.
An evening pause: A different kind of bridge, located in Russia and one that I wouldn’t speed across. Built originally as a railroad bridge to cross the Vitim River, it is 1870 feet long and about 50 feet above the water. Note how many of the cross planks are not attached.
