The purpose is to explore the potential of increased supply chain performance by improved information sharing between suppliers and contractors in the construction project. Four suppliers are studied, representing different combinations of supplying materials with few or continuous deliveries during the project. The study shows that, in order to improve performance, suppliers need different information sharing practices depending on if they continuously present at site or have few deliveries. Based on this and information sharing literature, we have developed a framework of information sharing practice differentiating what suppliers need, including how and when to exchange it.
