Knowledge management has largely been considered from the perspective of internal generation. It is posed that external provision will increase due to the diversity of problems and scarce resources, the arising issues being explored through a case study. The aim is to explore this process for construction projects. It will be shown that the successful delivery of knowledge services for the construction industry depends upon the way in which the provider conducts its marketing and the operation of gatekeepers in the project organisation. These issues are explored in relation to the main concepts and theories, applying and evaluating these through the case study approach.
