ABSTRACT
The AEC sector is characterized by a particular production mode (Chemillier 2003). It is different from other industrial sectors because construction relies on a unique order, which leads to the execution of a prototype. Moreover, the team is constituted for the duration of the project and this is the source of difficulties to create and maintain durable relationships between actors. At last, construction activity is situated. It is performed on the building site and consequently the way of proceeding has to be adapted to the specificities of the terrain.
