Sound project management is an important pillar of success for a construction company. Project schedules are the primary tools for communicating the thinking and planning by the management team to all the stakeholders in a construction project. Traditional project scheduling software have become an indispensable tool for managers in various projectoriented industries for tracking the schedule, the budget and resource requirements of a project as well as for preparing reports, providing on-line access to project information and communication with the members of the project team. However, these benefits are realized only after the project information is entered into the computer and updated periodically. Setting up a computer schedule for a construction project requires entering into the computer not only all project activities and their durations and resource requirements but also organizing and sequencing of project activities. This requires considerable time and effort and consequently a full-scale time study is not usually performed for all projects. Computer Aided Drafting and Design (CADD) or Computer Aided Drafting (CAD) programs enhance the way in which a model is developed but they still represent real construction objects as a group of lines. xv New parametric CAD software is revolutionizing the way engineers and contractors work and can significantly increase construction management productivity by substantially reducing the manual work necessary for automatic construction scheduling. The data model of new parametric CAD software allows easy exchange of building design information among various software systems during design, construction and service life of projects. Research is underway at Isra University to investigate how new parametric CAD software such as Autodesk Revit can improve construction scheduling and project control functions. The main objective of this research is to find a simple and confident way for transferring the necessary project information from a CAD model to scheduling software and streamlining sequencing and organizing project activities. Achieving this objective will eliminate one of the most tedious and time consuming steps in creating a construction project schedule. The study proposes an expert system approach to extracting project information, adding complementary scheduling information and transferring them to scheduling software. In this approach, firstly, a 3D model of the project is created using project’s digital Revit CAD files. Secondly, Knowledge based Expert system is developed using Visual C#.net. Finally, extraction, organizing, sequencing and transferring of project elements to scheduling software is performed during a run of developed program. This program reduces the tedious task of listing, organizing, sequencing, and transferring construction project information to scheduling software and provides flexibility as any change in design model reflected directly to scheduled plan.
