2 Storey Bldg in 3 Hours – 10 stories in 48

A Building in 3 Hours

3hrBldg A Chinese company has successfully 3D printed a five-storey apartment building and a 1,100 square metre villa from a special print material.

While architectural firms compete with their designs for 3D-printed dwellings, one company in China has quietly been setting about getting the job done. In March of last year, company WinSun claimed to have printed 10 houses in 24 hours, using a proprietary 3D printer that uses a mixture of ground construction and industrial waste, such as glass and tailings, around a base of quick-drying cement mixed with a special hardening agent.

WinSun has further demonstrated the efficacy of its technology — with a five-storey apartment building and a 1,100 square metre (11,840 square foot) villa, complete with decorative elements inside and out.

The 3D printer array, developed by Ma Yihe, who has been inventing 3D printers for over a decade, stands 6.6 metres high, 10 metres wide and 40 metres long (20 by 33 by 132 feet). This fabricates the parts in large pieces at WinSun’s facility. The structures are then assembled on-site, complete with steel reinforcements and insulation in order to comply with official building standards.

Although the company hasn’t revealed how large it can print pieces, based on, they are quite sizeable. A CAD design is used as a template, and the computer uses this to control the extruder arm to lay down the material “much like how a baker might ice a cake,” WinSun says. The walls are printed hollow, with a zig-zagging pattern inside to provide reinforcement. This also leaves space for insulation.

This process saves between 30 and 60 percent of construction waste, and can decrease production times by between 50 and 70 percent, and labour costs by between 50 and 80 percent. In all, the villa costs around $161,000 to build.
And, using recycled materials in this way, the buildings decrease the need for quarried stone and other materials — resulting in a construction method that is both environmentally forward and cost effective.

In time, the company hopes to use its technology on much larger scale constructions, such as bridges and even skyscrapers.

10-storey building built in 48 hours in Mohali (India)

Mohali_10_storey_building_complete_295_1Earlier at Mohali (Chandigarh – India) a 10 building was delivered within 48 hours.
The red and grey facade building, Instacon, stands tall. Work on the building’s construction started around 4:30 pm on a Thursday. By Friday evening, the building saw seven floors in place.

As the deadline of 48 hours approached, all the 10 floors of the building were in place even though the glass-panes on the windows and other fittings inside were still being put by the workers and engineers.

The building used pre-fabricated material, including 200 tonnes of steel.
“Our effort was to put the 10-storeyed structure in place within 48 hours. We wanted to prove that this could be done. That feat was achieved well within 48 hours. Just some finishing touches remain. This is only a sample structure,” an official of Synergy Thrislington infrastructure company said.

Entrepreneur Harpal Singh, who heads the Rs1,000-crore infrastructure company, had promised that the 10-storey building would be completed within 48 hours.
“This is the first building of its kind in the country to be built in just 48 hours. The model has been cleared for Zone-V seismic area, the highest risk area (for earthquakes),” Harpal Singh, who owns the JW Marriot Hotel in Chandigarh, said.

Over 200 skilled workers, technicians, engineers and equipment were engaged in the building construction. The material being used was manufactured in the past two months in a nearby factory. “No bricks and sand has been used. The outer wall is a double-skinned PUF panel. The cost is almost the same as of conventional construction material. It saves a lot of time that goes into construction otherwise,” said officials at the site.

Harpal Singh said that the idea to construct such a building came to him when he was constructing his own house, which took two years to complete – thanks to truant workers.

  1. I am a Member of Commercial Premises co-op Society, Society has completed 3 years since established, In 3 years I never attend the meetings and AGM. Since long time I hearing that there is some GOLMAL in society,In June end-2015 I write a letter to Society for complete detail of me since society start Function. But the reply by society is that until now I dint attend the any meetings or Agm. so i am not liable to get information, But I am paying maintenance charge regularly. After some time I received letter from Society secretary that your letter is received and its forwarded to accountant.
    In my 2nd letter I raise some Quarries on management in reply society put my name as a defaulter name in public, they don’t issue me notice also,please guilde me what steps should I Take.


      Your Society is positively in the wrong and action against them can be initiated against them under Section 146 of the Maharashtra Cooperative Act. This section entails 6 months imprisonment and fine upto Rs 10000 for each and every member of the Managing Committee. You may make a file of complete documentation and approach the Registrar with the documents for necessary action.

      Since there is an offence committed under the Indian Criminal Act also – forgery – you may lodge an FIR with your nearest police station – that will help you in your 146 case.

      Not replying to your letters and declaring you a defaulter is again illegal. However if for any reason – you have held back the Society’s payments, please clear those immediately. For declaring a defaulter they are not bound to inform you – you are suposed to keep a track yourself – anybody having outstadings over 90 days is considered a defaulter.

  2. Further I want to say that existing society have legal case is in High Court, Society collect the amount from every member under Legal Expense Head, collecting amount is fix deposited in bank, my argument with them is to credit the amount on individual name and what ever expenses should be debited equally, and what ever interest earning should be credited in personal name, but they refuse,
    further they preparing maintenance bill of 3 month ( quarterly ), and due date of payment is 50 days from date of issue is correct please advise me


      Whatever expenses on the legal case in the High court, the society can collect on actual basis and not hypothetical amounts every month.

      The moot question is if collectionof this legal expense was passed in any AGM. Even if it has been passed, it cannot be collected. What can be collected is the money the Society has actually spent as legal expenditure.

      That also has to be analyised by the auditor – whether ii is society related expenditure, or has become a legal issue due to someone’s ego battle. If it is an ego battle – the person concerned will have to pay from his pocket, the whole society cannot be pay to some committee member to settle his personal ego issues.
      Moreover amount thus collected cannot be put in fixed deposit. it has to be spent on year to year bases.

      Raising of bills every quarter is okay, as long as they give allow you to pay in three instalments, and for every instalment – the society gives you a credit period of 30 days from the 1st of the month. It is not date of issue… the society is bound to raise the demand notes on exactly the 1st of every month – even if you receive the bill late, your payment period remains the 30th day of the month
