Abstract

This paper presents an update of a study carried out by Etges (2018) in which an approach to answer the question about the level of value adding activities in Brazilian companies is presented. Taking into consideration the concepts of Lean Construction, adding value and wastes, and Value Stream Mapping (VSM) allied to the perspective of Operational Excellence, the study was conducted in 26 different companies divided into 7 categories of construction works, namely: airports, buildings, renewable energies, highways, Intracity, pipelines and railways. The analysis of the methodology consisted of characterizing the concepts of wastes and of the Value Stream of processes, and this was added to field analyses using the Work Sampling Method (WSM), which consists of measuring and identifying the level of wastage and adding value to the operation at the place of execution. The results show a low level of activities that add value in the sectors analyzed, representing, in the general analysis, 28% of the total time in manhours available. The results are also categorized by the predominant wastes in each category of construction works, and, in the general analysis, 48% of the wastes are related to Waiting. This analysis makes it possible to identify great opportunities for reducing waste and it is extremely important for the construction industry to promote critical actions aimed at leaner construction management.
