The construction phase of a large project requires the selection of the most appropriate construction techniques and the strict co-ordination of a large number of activities and resources. The effectiveness of selection and the co-ordination efficiency significantly influence total construction time and cost. 

This work package aims to promote, by means of artificial intelligence techniques, a concurrent engineering approach to the geotechnical construction works. It will contribute to the selection of the most appropriate “design for construction” solution among all possible alternatives, and the identification of the need for specific site preparation techniques, providing a feedback to the design phase.

A Geotechnical Works System for model-ling, simulation and co-ordination of geotech-nical construction activities in large scale engineering projects has been defined and implemented. The term "geotechnical const-ruction activities" indicates field activities requiring support of the geotechnical designer, or related to earth and foundation works.
Conflicts in the construction phase of geo-technical works are more the rule than the exception. Sometimes local aspects, not fore-seen during the design phase, such as buried pipes, or a critical ground water table, may impact construction methods and time.

The system can review construction activities, which can be verified by means of simu-lation techniques. For complex and inter-related activity configurations, the simulation techniques are the most appropriate approach to forecast the stage of work completion versus time, that is "what is needed and when". The results of such analyses can be compared with the original construction plans for verification.  Hence, the construction simulation enables optimal allocation of materials, labour and machinery resources. The results of the simulation are used as a feed-back for the design/construction plans of the facility. The system will be composed of several modules.
