A quantitative assessment of the environmental impact of construction activities is useful to identify the Received 20 April main environmental impacts and to improve their environmental footprint.
This study presents the life Received in revised form cycle assessment of an earthwork project. The results show that earthwork activities entail important 13 November environmental impacts; mainly energy consumption, global warming and human toxicity.
This study Accepted 20 November proposes and implements cleaner production strategies, based on the hierarchy of waste management, to Available online 2 Resolucion cra 376 de 2006 improve the environmental performance of the earthwork project.

The approach allows reducing the amount of soil to be used by the earthwork project. Moreover both the diesel consumption and the Keywords: This coincides with a saving of about 1. Introduction one of the most serious environmental threads of our time Benhelal et al.
Construction is not an environmentally friendly process Li et al. As construction increasingly became a pollution tant progress on the way to resolucion cra 376 de 2006 partly due to the source, the pressure on the sector for improving its environmental implementation of ISO and related standards.
However, most performance has increased Shen et al.

The expansion of the efforts focused on the sustainability of construction materials, construction industry is increasingly associated with sustainable rather than on the construction resolucion cra 376 de 2006 Ding, The main residues are: Construction The earthwork has limited impacts as compared to the processes also generate large quantities of greenhouse gases GHG construction process as a whole.
It involves the manipulation and Li et al.

An example of the LCA of an earth- the production costs Dipotet, There are differences between these two stages. Also, Angelopoulou et al. They show that the planner has to make assumptions.
At the contract stage, when the earthwork stage is a major contributor to GHG emissions. One more data are available including data regarding other non- aspect of the LCA resolucion cra 376 de 2006 that commonly some information relevant for earthworks activities that have been planned at tender stagethe its development is of limited quality or not available.
De earthwork activities are regenerated in an iterative manner.
LCA related to data quality and data collection resolucion cra 376 de 2006 indicate that The issues associated with traditional contracting methods of in most LCA studies implicit assumptions are made. As a result, an environmental impact assessment EIA method has been in recent years, approaches changed towards the integration of project combined with cleaner production CP Fijal, ; Salvador et al.
According to Tukkerthe underlying approach to Arts et al. One important difference Tukker, is that the stages of construction projects with the contracting stage. Construction projects are not subject to a bidding process. Also, considering that the income of impact of the data compiled in the inventory.
Therefore, considering construction companies depends of the volume of the project, the similarities of EIA and LCA, CP could be also combined resolucion cra 376 de 2006 LCA usually earthwork projects are over dimensioned, which increases aiming to reduce the environmental impacts of an earthwork project.
