The present research is the presentation of a model for implementation of expert systems for planning construction projects. The main idea of this study is that by using expert systems as a subsystem of the project knowledge management system, it could make these systems operational in planning organizations and also capable of saving and retrieving part of the planning knowledge of construction projects, in order for managers and planners of organizations to make decisions. The technical construction planning expert system model is a prototype model that can memorize and present construction project planning knowledge in three stages: feasibility, details, and workshop planning phases. According to the main goal of this research, designing the
model has been done as a knowledge management sub-system in the project based organizations, considering the specifications of construction planning knowledge, which includes planning processes, planning rules, planning
auxiliary documents and the technical know-how of construction stages of construction projects, in order to solve the problems of expert systems development. For this reason, the processes of expert system implementation in the organization have been prepared using knowledge management models. Due to
expert system model development, it has been amended and completed using specialties tailored by the special features of construction planning companies and construction planning experts of the case study company, and also by considering the opinions of planning experts in the NOSAZAN Company; one of the greatest leading companies of state construction management. To prepare this model, first, the planning process, knowledge titles and information fields needed for executing each knowledge component process are identified.
Then, these components are classified into six groups of knowledge categories. In the next step, appropriate systems are specified for each category. With a combination of these systems, the final technical model of the construction planning expert system is designed. By methodologies obtained from valid models and results extracted from questionnaires, the expert system implementation model was evaluated and recommended .
