Levantamento de dados para elaboração de orçamento de estruturas pré-fabricadas: estudo de caso em uma empresa na cidade de Toledo, Paraná

Abstract

The evolution of prefabricated production, associated with the advantages conferred by the construction system, such as cost reduction and increased rationalization of construction, has made it promising, attracting new investors in the industry and thus increasing competition among companies. To ensure their competitiveness, it is essential that companies offer prices equivalent to the market, so they must conduct the service with the lowest possible cost, while maintaining quality. This is only possible by budgeting with consumption rates and real costs of the inputs. Of the several ways to prepare a budget, the analytical budget was chosen, which has an in-depth study of the execution of the services, resulting in more precise data. For this reason, a case study was implemented in a prefabricated industry in the city of Toledo, Paraná, with the objective of collecting data for the preparation of the sales price of some prefabricated elements produced by the industry. The reinforcement and concreting activities were monitored for a period of three months, with measurements being taken at least three times a week, alternating the days and three work shifts. After gathering the data for material consumption and workmanship, the composition of unit cost for each prefabricated element were elaborated. It was observed that the cost defined by the company is the same for all elements and cross sections, while the cost obtained varies according to the type of element and its section. Furthermore, the unit cost practiced at the company is higher than that obtained in this research, by an average percentage of 30%.
