Is it possible to make a structure by ICE !?

Who said structures can only be built by concrete, steel and rough materials !?

Let us have a look on this fantastic structure , I bet that every civil engineer is excited to work on such project !

IceHotel

ICEHOTEL is the world’s first hotel made of ice and snow. Founded in 1989, it is reborn in a new guise every winter, in the Swedish village of Jukkasjärvi – 200 km north of the Arctic Circle. The Torne River, the arts, and creating a setting for life-enriching moments are at the heart of it all.

Building the ice hotel isn’t so much an annual process as a never-ending one. But if you had to specify a starting point for the endeavor it would be sometime in November, when the river freezes over. That’s when the production team, led by production manager Alf Kero, sections out a 14,000 square foot swath of ice with red plastic rods typically used to mark snow-covered roads. All winter long, Kero and his team will cultivate and monitor this patch—which will eventually become the raw material for the next year’s hotel.

An average of two meters of snow blankets the village over the winter, but workers plow this special patch of river with a front-end loader to keep it clear of precipitation. This ensures that the ice grows downward, into the still waters of the river below, rather than hardening upward. The result is ice that is crystal-clear, free from bubbles and cracks, and it’s this naturally formed glass-like ice that the hotel has made its trademark.

In December, during the weeks that the sun doesn’t come above the horizon, the entire river, which reaches depths of more than 60 feet, is frozen solid. Because of all that ice, the temperature in Jukkasjärvi can be 10 to 20 degrees colder than the nearby mining city of Kiruna, just 11 miles to the east. But by February, as the days are beginning to lengthen, the river is slowly beginning to thaw from its bed up. This is when the team begins to gear up to harvest the ice for the next year’s hotel, carefully monitoring its thickness. When it’s around three feet thick, usually in early March, it’s time for the harvest to begin.

The ice patch is gridded out into squares that measure roughly 20 square feet (6 square meter), and then the team slices the ice using a vertical saw mounted on a front-end loader, specially designed for the task by the team with the help of a local construction firm. Each cube, weighing nearly two tons, is lifted out of the river with a forklift. “The river flow is quite gentle in the area where we pick up the ice blocks,” Kero tells me, “but the ice can be slippery and at times it can be very windy so it is important to wear suitable safety equipment and ensure that the staff is trained and working in teams, never alone.” Altogether, the team harvests 5000 tons of ice this way.

Once a block is out of the river, the crusty top layer is sawed off, and then the blocks are sorted by clarity. The clearest of them are designated for use in the hotel rooms and to manufacture glasses—for the hotel’s bar and three more Ice Bars the IceHotel runs, in Stockholm, Oslo, and London. During the summer, while the temperature outside reaches the 60s and the sun stays up all night, the giant blocks sit in two giant sub-freezing warehouses.

As winter begins to descend, it’s time to get ready to start construction on the new hotel. It takes a team of about 100 people—including builders, artists, lighting engineers, snice casters, tractor drivers, and the art and design group—to build the structure. In October, as the river begins to freeze, the production team prepares the grounds and wall moulds and makes sure electricity and sewage are in order, while they wait for the temperature to drop. A support wall is erected out of steel vaults.

When the ground freezes and there’s been a week of temperatures below 19 degrees Fahrenheit, it’s time to start spreading snice for the hotel floor. Snice acts like a paste and looks like the crust that builds up in a malfunctioning freezer. It’s made by pumping water from the river and blowing it through “snow cannons,” which results in tiny ice particles mixed with air. The substance is structurally stronger and more resistant to the sun than sheer ice, and has the insulating qualities of snow. A hotel built of pure ice would be much colder inside, and would melt quicker in the spring.

To construct each corridor of the hotel, a row of arch-shaped steel vaults are erected, and then sprayed with snice and left to set for a few days. Once they’ve frozen, the vaults are lowered onto skis and pulled out with a tractor. Internal walls are built using the same process. Once the corridor is divided into a number of rooms, doors are cut using a chain saw, and the LED lights are installed. (There’s no plumbing—if hotel guests have to use the bathroom in the middle of the night, they must venture to an attached warm building. Ask me about this some other time!) When the rooms are completed, the team stocks some of them with extra ice blocks—these will become the art suites.

For more than two weeks each November, the visiting artists chosen to create the year’s art suites work in the freezing rooms, using chisels and chain saws to carve the rooms they have planned. Then in early December, once the reception area, bar, and at least one wing of rooms are ready, the hotel officially opens for business. From then until the structure becomes unsafe to occupy in April, visitors will fill their days with ice sculpting lessons and snowmobile sojourns
