Developing a taxonomy of transportation waste in construction production processes

Purpose: The purpose of this paper is to present a taxonomy of transportation waste in construction production processes based on lean construction (LC) principles. Design/methodology/approach: The research methodology used is case study and the main stages for the identification of the transportation waste in two construction projects were: mapping physical flows; measurement of transportation time; and monitoring of transportation waste events; assessment of the taxonomy. Findings: The main contribution of this paper is the proposition of a taxonomy of transportation waste in construction production processes through the understanding of the transportation waste causes and consequences. Research limitations/implications: Although the literature reviewed addresses sources from different parts of the world, the case studies performed are limited to one country, Brazil. However, the studies were carried out in two different construction sites separated by more than 3,000 km. Practical implications: All data collected during the taxonomy application can be organized in order to develop an improvement plan. Moreover, if data collected is disseminated, there is the potential to increase the efficiency and effectiveness of the construction sector. Social implications: Although the paper does not explore in depth the impact of the study on society or policy, the theme of waste minimization is focused on cost reduction, and one way to do that is through the flow management for waste minimization. Originality/value: The paper discusses the concept of transportation waste of production in construction based on LC philosophy, through the understanding of its causes and consequences.
