One of the main challenges that developing countries face is the need to increase productivity. In Chile, the most important productivity gap in both mining and construction industries is the lack of operational efficiency, caused mainly by the low adoption of advance management methods. Hence, considering the need to increase productivity through operational efficiency, lean...

Integrating Building Information Modelling (BIM) to on-site meetings in the construction phase has been a challenge to general contractors mainly due to the inflexibility of the current practice in grouping and organizing models to facilitate rapid, on-the-spot model queries. We have developed an automation tool that supports the automatic grouping of models according to a...

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...
