After its transport to the construction site, one marries prefabricated can be mounted, be closed and occupied in a matter of days. Saving of materials used in work, with the elements prefabricated in buildings or the modular houses, is possible the construction or assembly in dry, that is to say, can be done without mortar. Reduction of the residues of the construction, when arriving the prefabricated components at work, would be reduced the amount of residues generated in the land where the construction is realised (packing, breakage of pieces ) One affirms that end items can be created that allow the energy saving. For example, panels for houses prefabricated with a greater heat insulation would be constructed than the one that usually is applied in the majority of builds them. The prefabricated components would be constructed with materials of the same quality that in the work or even of quality superior, since the components and process of production would be subject to a greater control in the plant (environmental conditions, quality controls ) In addition, the materials less would be exhibited to meteorological inclemencies, since the assembly is realised in a brief period of time and they would not be exposed to adverse climatic conditions during months.

Also they would own a greater strength to resist during the transport and assembly. By all this they would be also more resistant after his construction. The prefabrication of constructive elements could lay the way towards the creation of buildings in which outside simpler desensamblar or deconstruir when these arrive at the end of their life utility and to thus be able to use the materials in another place. Also it would be possible a greater control on the processes and materials, as much in the management of residues generated (simpler in plant than in work) like in the toxic product elimination.
