Mapeamento e análise das causas de retrabalho em obras públicas

Abstract

The public administration is responsible for more than 30% of the investments in constructions in the country, however, there is a great challenge in the containment of constructive errors to be worked on, rework is seen as a cultural problem in civil construction, and this practice has become largely standardized as part of the public construction process. The presence of reworks means that the product is not in proper compliance and will need to be redone, and with that, they cause several defective deliveries, delays, additional costs and damages, both to the public coffers and to the population. The processes that involve the construction of an enterprise are composed of complex and interdependent activities, making it more susceptible to errors, like design, labor and process losses. The methodology used to map the causes of non-conformities was technical visits, interviews with professionals of the area and application of a questionnaire based on the Likert Scale, and then the results were obtained through the relative importance index, presenting the frequency in rework incidents occur. The critical factors showed the fragility of the public construction system and, therefore, the need to improve several aspects, in search of the eventual reduction of the factors that aim at the improvement and productive efficiency of the works in the country
