The study focuses on the sources of problems at the design and construction interface in large building projects in Saudi Arabia. To achieve the study objectives, a questionnaire survey was carried out to collect information on potential sources of disagreements at the project design and construction interface. Responses from 24 consultants were analyzed. The results suggest that the contractor's lack of comprehension of drawing details and specifications, involvement of contractor as consultant, time limitation in the design phase, design complexity and participants' honest wrong beliefs were considered as the most important sources of the project design and construction interface problems. On the other hand, project management as professional service, weather conditions, unforeseen problems and involvement of the contractor in design phase were least important sources of problems between professionals at the project design and construction interface in large building projects.
