IN-SITU REINFORCED CONCRETE BUILDINGS
 

In general, because of the large amount of materials and the various persons handling them in traditional systems, the application of quality assurance systems is more difficult and requires more time. Moreover, many construction materials lack quality assurance controls, meaning that the end product, a dwelling, lacks good quality. On the other hand, concrete is manufactured at specialised concrete plants, which guarantees its strength and durability. The experience of many developers when subcontracting the various works units is mainly negative because of some failure of one or more subcontractors along the chain, with subsequent delays for all the others. The date on which they should have delivered is not met and they have to deliver a different project, thus delaying the beginning of these first works and delaying those coming after them and so on. For example, the delay of a structural or dividing wall construction firm by one month could have a “butterfly effect” and cause a total works cycle delay of six months depending on its complexity. The works programme and construction process are better defined using the in-situ reinforced concrete dwelling construction method and this results in improved contract and job control. By eliminating a significant number of materials and personnel, better quality assurance can be applied. For example, the concrete pouring process is all performed once at the same time, with monolithic concreting of framework and walls (exterior and dividing walls), whereas a greater number of materials and personnel are necessary in the traditional system and hence, it is more difficult to guarantee uniform quality. Since the entire dwelling is modulated with formwork, squaring, levels and plumbing are practically perfect. Consequently, tile-laying and other finishes are more regular giving increased quality to the dwelling finishes. In general, concrete dwellings make better homes, with high quality in all senses. This reduces the number of after-sales calls which, apart from saving a lot of after-sales service time and resources, it permits concentration on the business and increased promoter prestige.
