Sistemas construtivos para habitação de interesse social: estudo de viabilidade econômica para implantação na cidade de Barreiras-Ba

Abstract

The population growth in the urban zone reflects the housing deficit which still is a current issue in Brazil. This way, it becomes more and more evident the need to make up for the high demand for housing through public politics and governmental programs. In order to solve this problem in the city of Barreiras-Ba, the city has the support of a local plan of social interest housing (PHLIS)This work has the objective of identifying the building process to facilitate the implementation of more social interest housing. As an object of study, we acknowledged as inspiration the HA+MO project, as well as the following building systems: conventional masonry, load bearing masonry, and concrete walls molded on the spot. For this analysis to become feasible it was necessary to adjust the project to the particularities of each system. Therefore, it was developed a budget with a comparable purpose which had as support the elaboration of the building cost estimate chart, according to the system being used, the SINAPI - National System of cost research and civil construction rates-, with release date from technical reference on 07/02/2022, not exonerated for the state of Bahis. The concrete walls molded on the spot show more beneficial values if compared to the others, presenting lower cost if they are built in only one housing unit or in large scales.
