There are two moments in Antarctic constructions. First houses, storehouses, shelters, power plants, and cold-storage plants, were made in wood until 1960.

At present wood has been replaced by double-wall plastic panels, which facilitate the assembly of modulus mounted between them, and air is used as insulant, by filling them with expanded polyurethane.

They are also reforced with tensile steel wire. The new technique is to close houses, stations or shelters at 360º.

During summer months, stations and shelters are open to carry out scientific research plans. These stations are so-called transitory.

There are also scientific camps, set up at transitory stations and having the aim of carrying out scientific tasks scheduled by annual plans, e.g.: historic monuments maintenance, soil, sea water and ice sample collection, population census of fauna and meteorological information.

All these data, taken annually, provide a series of publications sent to the international Antarctic scientific community, and observing one of the provisions of the Antarctic Treaty.
