Integrating LOIN-driven Information Exchange Connected to Construction Production Planning

Abstract: In construction projects, frequent changes to time planning result from unforeseen events, impacting both timing and scope of information exchanges (IE). Currently, IE planning and production planning are performed independently with limited integration between the two, leading to inefficiencies when changes are needed. This study proposes a unified approach facilitating Level of Information Need (LOIN) to systematically identify and link to required IEs for the production phase. The mapping was co-developed with and evaluated by industry professionals to ensure practical relevance. Integrating LOIN-driven IE mapping into production planning enhances responsiveness to schedule changes by providing structured guidelines for information delivery.
