Description
Summary:Lean Construction is a philosophy than is oriented in the management of construction projects following the principles of continuous improvement, whose main objective is to reduce or eliminate activities that do not add value and optimize the activities that do, showing results in a decrease of the cost, an increase of the quality and a reduction in the term of delivery of the constructions. The tools of this philosophy have been implemented in the construction of buildings, housing and mining. However, in pavement infrastructure projects, little has been investigated. The purpose of the present research work is to identify the wastes in the paving construction processes applying the Lean philosophy. For this purpose, a comparative analysis was carried out between two companies dedicated to road construction to evaluate the waste generated. Field data were taken daily through the recording of videos and forms records. The results of this study confirm that the processes are affected by the same causes as in other types of construction projects, although to a lesser extent, as the road works present more productive work due to the effect of the continuous flow system characteristic of these works. The way in which the production system affects loss reduction requires further study.
