At present, contracts are evolving to a collaborative form such as Integrated Project Delivery (IPD) or Multiparty agreements. Some states are using this new way of interaction to reduce fragmentation and self- interest of the AEC sector component. The construction sector’s productivity index is the same in the last decreased, on the contrary the one of the mechanic industry increased. Collaborative contracts are the way to improve the sector profitability. Its aim is to enable and develop collaboration between the owner, the designer and the constructors. New technologies evolution imposed a change in the contract type. A comparison between USA type and UK type is presented. This one is becoming a new standard for European contract. This new standard has proven to have demonstrated to generate an increase in productivity and a decrease in waste of time in the design, in construction and in operational phases. The changing of key participant’s scope from an individualist perspective to a collaborative one, it allow achieving the building quality. The project requirement is the necessity to better satisfy the owner needs, to clearly identify the contractual and extra-contractual responsibilities of individual operators. These are the reasons why Building Information Model and collaborative contracts are conceived to work on the same project.
