-      Building Information Modeling (BIM) is one of the most advanced developments in engineering, The second generation of modeling tools is the result of decades of research and development, A virtual model, one or more, is created to support the design process throughout its stages, It is a simulated for the reality of the real project, BIM modeling is created to simulate building design, construction and management, Which will improve performance beside calculate cost while not wasting time, The feasibility of using BIM is to adopt a more efficient design of buildings by collecting and using building information and data to improve its characteristics such as insulation, ventilation, lighting and all mechanical systems in the building. This technique originated from the development of 2D software such as CAD systems, with the rapid development and addition of the time factor, calculation of quantities of materials , cost and the management of the building facilities during the life cycle turn to 3D programs, up to XD development, which is reflected directly On design, construction and post occupancy. One of the most important areas for using BIM modeling is the detection of design errors and conflicts before construction and to processed off-site (pre-processing) elements by accurate digital representation of these elements.In the operational phase, BIM modeling can be integrated with BMS systems to monitor building performance in smart buildings, for example, intelligent control of electricity, water and other applications, thereby improving building performance. The stages of using the BIM building information models are in eight stages, starting with initial ideas, design, implementation, details, analysis, etc., and finally the operation and maintenance models.
-      Types of BIM building information models, according to their use, including project site design models, architectural drawings, structural drawings, mechanical, electrical, sanitary, building fixtures, and complementary elements. BIM tools have been developed to integrate most data with the design and access model to identify and control loss of energy in the building, which helps improve sustainable design in the building.
