We can think that the advantages that are associated to the prefabricated ones have more to do with the facility and the effectiveness at the time of managing putting in work, and even with saving resources (also human), that with the ecology. To continue using material intensive in energy and polluting agents in its manufacture is not environmentally viable. To maintain or to continue the dependency of the transport long-distance of the materials that are not going to conform the building either is it. Perhaps in spite of the improvements in the industrial productive processes, finally there is nothing else no cost-cash, economically and environmentally, that buildings that include local or regional technology and materials of low impact, constructed by local manpower. Advantages of the prefabricated ones Some of the factors that the defenders of this type of construction (of prefabricated houses) aim as benefits are the following: The construction would become a continuous activity, at least in the production plant, in which throughout the year the components of the future constructions would make. This would allow that the workers of the sector of the construction, or a part of them, they would have a fixed use less subject to the variations of the rates of the sector.
Bound to this, we found what other promoters of the construction defend like an advantage: the fact that the manpower that would work in these production lines would not need a specialized formation. This is interesting to the promoters of houses in countries in which, for example, a great number of wood houses is constructed habitually, like in the United States. This new system of construction would allow to do without a professional carpenter and to use to a worker nonspecialized in the production line. By all means, this worker would receive a lower wage. The rapidity of assembly, as much in the case of modular houses like in buildings with part of its prefabricated components, uses excessive respect the run time of the work, in some cases to half, although it is more spectacular in the case of houses totally constructed in factory.
