This thesis explores the potentials of adopting loose-coupling concept in interface design of knowledge management systems for construction industry. For this purpose a prototype was developed which enables users to access relevant information to their work without getting engaged in any extra activity to translate their needs into systems’ languages. The need to maintain, capture and reuse this knowledge within the organization in order to make its effective use in the long term and in order to avoid costly and time-consuming relearning; has led to a profound branch of specialty in the management disciplines referred to as knowledge management. Since the introduction of IT to knowledge management the term knowledge management system (KMS) in a broader use refers to ICT systems particularly devoted to the creating, retrieving, storing and distributing knowledge in an organization.
