China Builds A Bridge In Just 43 Hours (Video)

Caught On Tape: China Builds A Bridge In Just 43 Hours:

When you have a billion people willing to work instead of expecting free “stuff”, anything’s possible… Earlier this year, a Chinese construction company had erected a 57-story skyscraper in just 19 days. This time the Chinese have built an overpass in mere 43 hours!

Workers took apart the old structure of Beijing’s Sanyuan Bridge in a few hours. Then they brought an entire piece of concrete to bridge the gap and paved it over, reports Citylab.com.

To build the bridge, over 1300 tonnes of new surfacing material was used which save months of commotion and traffic woes. For the first time in Chinese workers tried out a new ‘integrated replacement method.’

 

The Deadly Global War For … Sand

The Deadly Global War for Sand (Wired, March 26,  2015):

The killers rolled slowly down the narrow alley, three men jammed onto a single motorcycle. It was a little after 11 am on July 31, 2013, the sun beating down on the low, modest residential buildings lining a back street in the Indian farming village of Raipur. Faint smells of cooking spices, dust, and sewage seasoned the air. The men stopped the bike in front of the orange door of a two-story brick-and-plaster house. Two of them dismounted, eased open the unlocked door, and slipped into the darkened bedroom on the other side. White kerchiefs covered their lower faces. One of them carried a pistol.

Inside the bedroom Paleram Chauhan, a 52-year-old farmer, was napping after an early lunch. In the next room, his wife and daughter-in-law were cleaning up while Paleram’s son played with his own 3-year-old boy.

Gunshots thundered through the house. Preeti Chauhan, Paleram’s daughter-in-law, rushed into Paleram’s room, her husband, Ravindra, right behind her. Through the open door, they saw the killers jump back on their bike and roar away.

Meet The World’s First 3D-Printed Apartment Building (Made in China)

“Simply incredible.”

… and most probably also incredibly toxic!


3D-Printed Apartment Building

Made in China – Meet the World’s First 3D-Printed Apartment Building (Liberty Blitzkrieg, Jan 20, 2015):

The following story is simply fascinating. Provided this and similar structures are able to stand the test of time, it will have unbelievably deflationary consequences for home prices across the world.

I first highlighted this company, WinSun, last year in the piece: Zillow Study Shows 1 in 3 Homes are Unaffordable, Meanwhile Vacation Home Sales Soar. Here’s an excerpt:

This month, architects in Amsterdam started work on the world’s first completely 3D-printed house. It’ll take three years and quite a bit of money to finish. Meanwhile, in Shanghai, a company claims to have printed ten houses with inexpensive industrial scraps in less than a day. What’s the difference?

It depends on your definition of 3D printing. Both projects are using massive 3D printers; in Shanghai, it’s 490 feet long, 33 feet wide, and 20 feet deep. Rather than expensive plastic, though, the Chinese company WinSun Decoration Design Engineering Co is printing with a concrete aggregate “made in part from recycled construction waste, industrial waste, and tailings,” according to the Architect’s Newspaper. Each of these homes costs less than $5,000.

Chinese Firm Showcases 3D-Printed Houses (Video)

Chinese firm showcases 3D-printed houses (RT, April 27, 2014):

A Chinese company is using 3D-printed blocks to build cheap and quickly assembled houses as a possible solution to the urgent problem of modernizing housing conditions in Chinese villages. The blocks are made from a mixture of sand, concrete and glass fiber, materials processed from common construction waste, which is pumped layer after layer through the top of a 6.6-meter-tall, 32-meter-long industrial printer.

China: Recycled Concrete Houses 3D-Printed in 24 Hours (Business Insider, April 24, 2014):

A Chinese construction firm based in Shanghai has succeeded in building 10 houses each measuring 200 square metres in 24 hours by using an enormous 3D printer.

The houses are all eco-friendly and constructed from 3D-printed building blocks made from layers of recycled construction waste and glass fibre and mixed with cement.

Each home costs less than £3,000 to build.

Are Millions Of Business People At Risk of Dying In Collapsing Buildings?

Are Millions of Business People At Risk of Dying In Collapsing Buildings? (Washington’s Blog, Feb 13, 2014):

Death Traps?

Millions of people work in or visit high-rise buildings … assuming the buildings were more or less safe.

But it turns out that there is a severe, lethal risk of sudden collapse in even the best-made skyscrapers in America, Britain, Germany, Japan and other nations worldwide.

International Construction Firm Balfour Beatty Considering Drone Workers

International Construction Firm Balfour Beatty Considering Drone Workers (Technology Advice, Nov 8, 2013):

Most people associate drones with military and counter-terrorism programs, but Balfour Beatty CIO Danny Reeves wants to use them for a rather different purpose. Speaking at the Fujitsu Forum, he told Techworld that unmanned aerial vehicles could be used to build walls, and improve project efficiency.Balfour Beatty is a international construction and engineering firm that specializes in large-scale projects and building management. Their revenue for 2012 was approximately $17 billion, with an operating income of just under $500 million, so presumably they have the resources to commission a fleet of construction drones. Reeves also spoke of the potential for drones to monitor sprawling project sites, hopefully reducing communication errors and wasted labor on large sites.

To Improve Today’s Concrete, Do As The Romans Did … Whose Massive Concrete Structures Have Withstood The Elements For More Than 2,000 Years

To improve today’s concrete, do as the Romans did (UC Berkeley, June 4, 2013):

BERKELEY – In a quest to make concrete more durable and sustainable, an international team of geologists and engineers has found inspiration in the ancient Romans, whose massive concrete structures have withstood the elements for more than 2,000 years.Using the Advanced Light Source at Lawrence Berkeley National Laboratory (Berkeley Lab), a research team from the University of California, Berkeley, examined the fine-scale structure of Roman concrete. It described for the first time how the extraordinarily stable compound – calcium-aluminum-silicate-hydrate (C-A-S-H) – binds the material used to build some of the most enduring structures in Western civilization.The discovery could help improve the durability of modern concrete, which within 50 years often shows signs of degradation, particularly in ocean environments.

Greece: Economy Grinds To A Halt As New Construction Implodes By 66.6%

Greek Economy Grinds To A Halt As New Construction Implodes By 66.6% (ZeroHedge, Feb 12, 2013):

Some time ago we used to joke that the Greek economy, and by implication society, is literally falling apart due to its sacrifice at the altar of preserving the European, and thus global, status quo. It is no longer a joke, and the latest confirmation of the absolute halt in the Greek economy, which is now way beyond the liqudity trap and is now in a liquidity (and everything else) tiger cage is data on Greece Construction activity which according to data released on Tuesday by the Hellenic Statistical Authority is in complete freefall. From KathimeriniIn November 2012, total activity dropped 66.6 percent year-on-year in terms of building permits, 63.3 percent in terms of surface area and 65.4 percent in terms of volume.” Just 1,156 permits were issued across the country, corresponding to 197,000 square meters and 706,900 cubic meters. In the first 11 months of last year construction activity shrank by 36.4 percent in terms of permits, 30.3 percent in surface area and 28.7 percent in volume, compared with the same period in 2011. The statistics observed in private construction activity are virtually the same as the above, as activity in the public sector has effectively ground to a halt.

And for those curious how the people are surviving, the answer is simple: nobody is paying taxes:
