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...

This paper presents the benefits expected from collaboration on a high level research program aimed at removing the obstacles to radical renewal. Obstacles to that transformation are proposed, culminating in an appeal for collaboration to remove those obstacles.

This paper shows a Lean Construction method being implemented with a bottom-up strategy, using spontaneous improvement as a tool for the implementation. To introduce the changes, all workers were trained on how to manage and identify the 8 types of waste, and presented to a simplified A3 thinking approach as a problem-solving technique. The implementation...

Construction companies have difficulties to measure the performance of their efforts regarding the use and application of the Lean Construction philosophy. To serve as support for this development, a tool called DOLC was created to analyze and assess the degree of Lean Construction of a construction company. Based on the 11 principles of Koskela (1992)...

As off-shore prefabrication continues to gain momentum, supply chain management becomes increasingly complex for industrial modular construction projects and delays commonly occur to prefabricated modules. In order to make efficient utilization of limited module assembly resources (e.g., crews and bays) and reduce the waiting waste of materials on the module yard, a systematic optimization approach...
