Construction material suppliers have access to various types of information, such as construction data, price, production planning and logistics data. This information could be of great use for the different roles involved in a construction project if the right information is presented to the right role and through a user inter-face designed for best under standing by each role. This situation is not unique for the construction industry, but the specific context with temporary organizations (construction projects) that have to communicate with permanent organizations (construction material suppliers) combined with the fact that, at least, six roles (categories) of employees are involved in a construction project places challenges on the industry to achieve effectiveness. In this paper a process to develop a information interface between construction projects and construction material producers will be presented. Using an interventionist research approach with interaction designers involved, the process aim to guide the development of an application for exchange of information between the actors in the construction projects.
