The aim of the research is to shed light on the relationship between the concepts of Virtual design and construction (VDC) and building information modeling (BIM), and in particular to identify and evaluate the potential benefits of using a methodology based on the integration of the fourth dimension of (4D BIM) with virtual design and construction (VDC) and its impact on the preparation of the schedule and project planning and construction simulation. The research reviews a case study of "Pharmacists Syndicate building - Tartous branch", the building model (3D BIM) was created in Autodesk Revit 2020 ®, then the model clash was detected, reviewed and resolved, and the quantities were calculated on the Autodesk Navisworks Manage 2020 ® program, and the time periods for each activity were estimated according to the quantities, workshop performance rates and teams. Finally, time schedule was created in Bentley Synchro PRO 2020® software, the elements of the schedule was linked to the (3D BIM) model and the resources needed to implement each activity, then the construction simulation of the model was performed. The results showed the importance of (4D BIM) and the use of software in accurate modeling of all building elements and solving design problems before construction, which in turn has a significant impact on reducing time and cost of the project implementation. Model-based calculation of quantities helps to accurately estimate resources and times for activities. The importance of scheduling within a virtual environment based on the (3D BIM) model lies in the ability to digitally plan all aspects of a construction project, create and discuss different work sequences, in addition to managing cost, schedule, earned value, risk management, site integrity, logistical planning and mega-project management before and during implementation. However, we cannot only rely on software and technologies, but there must be an integrated methodology that organizes construction operations, and here comes the role of (VDC) Virtual design and construction as an innovative implementation strategy that adopts (BIM) building information modeling. As the success of any project depends greatly on the efficiency of the management and organization of its operations to achieve its desired goals.
