Analysis of the influence of Lean Construction and LEED Certification on the quality of construction sites

Abstract

Adequate planning of construction sites guarantees better efficiency, productivity, quality on the development of all work activities, optimization of the physical available space, workers' safety and motivation in performing their duties. The objective of this paper is to verify the influence of Lean Construction and LEED Certification on the quality of construction sites. The aspects analyzed were Temporary Facilities, Safety, Material Handling and Storage at construction sites by using a checklist developed by Saurín and Formoso (2006). Forty construction sites in the Metropolitan Region of Fortaleza (MRF), Brazil, were analyzed. The results pointed to a direct relationship between the implementation of Lean Construction and LEED Certification and the overall quality of work at construction sites. The concepts of Lean Construction are linked to a better quality of material handling and storage, temporary facilities and safety at construction sites. Also, the LEED Certification influences to a better quality of material handling and storage. Those two aspects combined make the construction site safer and more efficient, reduce material waste and cost, as well as increase the quality of the services executed.
