Perdas por making-do em obra rodoviária: um estudo de caso

Abstract

Making-do refers to a situation where a task is started without all its standard inputs, or the execution of a task is continued although the availability of at least one standard input has ceased. This category of waste can impact quality, costs and deadlines projects. Road works characteristics suggest a higher incidence of making-do. This work aims to identify the making-do in a road work, analyze the conditions that favor its occurrence and the resulting impacts. To this end, those responsible for planning, production and procurement were interviewed and the information collected was confirmed or complemented by the author's participant observation. It was identified that information deficiencies such as the incompatibility between projects and the budget spreadsheet and the beginning of activities without authorization from the inspection are frequent reasons for wastes due improvisation. It was also identified that among the main making-do wastes are those related to the difficulty of access and availability of resources to the work fronts distributed along the road.
