When studying the creation of a new venture, it is necessary to know its approximate cost, discovering its viable and reducing possible unforeseen. However, there is often no possibility of having all the projects related to the new work available, since each project has a cost, and the creation of the work is still under evaluation. Thus, a full budget is not possible, since it does not have all the necessary quantifies to carry out the work. In this way, an estimate is made of how much will be spent by the enterprise. The use of indicators and average indexes, try to facilitate the estimation of quantitative materials to be spent, using architectural parameters available in the preliminary stages of the project. Trying to contribute with this type of estimation, this work carries out a study on quantitative indicators necessary for the installation of systems of distribution of cold water and hot water in residential apartments. For the accomplishment of the work, data were collected from 32 hydraulic projects of residential apartments, of three designers of the city of Cascavel-PR. The apartments have areas ranging between 61.66m2 and 511.82m2, and from them were collected data referring to the quantitative elements of the water distribution system of each sanitary fixture, its areas, hydraulic wall lengths, and number of water points, then indicators and indices were elaborated, which were analyzed according to their coefficients of determination and variation. After the conclusion that it is not recommended to use the indexes and indicators obtained, due to the low correlations between the quantitative and drivers, since the quantitative ones are susceptible to variations due to structural and functional elements, an estimation was made by means of hydraulic wall intervals and areas, which were compared with two external projects to the sample and measuring their errors, seeking in this way, to contribute with alternatives that allow to estimate the inputs used in the water distribution system in apartments. |
