Planejamento de insumos em empresas de pequeno porte na construção civil

Abstract

Planning in civil construction is a consolidated practice among managers, however, it does not usually reach the level of detail in the planning of inputs. For this reason, a scientific research was carried out through a semi-structured interview, with 5 respondents, aiming to collect and analyze information about the management practices adopted in small companies that are operating in the market. It was found that the companies had different levels of maturity in relation to the level of planning, but that all of them carried out the planning of services to be performed on the construction site. The cause pointed out so that the managers did not carry out the planning of the inputs was that the question of the investment in innovation in companies of this size is culturally analyzed as only a cost, which makes the companies to neglect the investment to develop this planning. In addition, the lack of monitoring of productivity and consumption of materials in companies of this size also make it difficult to carry out the planning, because they end up not having data based on the reality of the execution of their services. With these data, a proposal for a material planning model was developed, using the planning of two common services in works: the masonry and the subfloor. Finally, it was possible to conclude that a system based on the materials requirements planning is a managerial tool capable of assisting small companies to carry out input planning and that, this practice can bring advantages to companies, such as the optimization of the flow of materials. cash and the reduction of stock stored at the construction site, thus improving the company's operation. In addition, the material needs plan is inserted in the context of lean construction, thus reducing the flow activities present but not extracted.
