According to Morrison, Building Information Modeling (BIM) is a process of organizing and generating building data throughout the growth of a project. Indeed, BIM is an actual-time, three dimensional, vibrant building modeling computer systems where business people can enhance productivity during generating constructions and designs functions (2003, p.4). Actually, this process generates BIM that connects geographical information, spatial association, constructing geometry, properties and quantities with all correlated building components. Certainly, “BIM generate a reliable digital account of an existing building for design management, appropriate construction document invention, cost approximate, construction scheduling and performance forecast” (Larner & Walter, 2004, p.36). Moreover, acquiring the capability to update information and attain an incorporated digital setting enable constructors, engineers’ architects and business owners’ clear objectives of their business organizations and capability to generate informed strategies quickly. The process of BIM entails geographic information, space, properties, capacity (quantity) and geometry of building constituents. Definitely, BIM is a useful course that reveals the whole building life cycle, facility process and construction operation. Why BIM Approach to Revit Revit is an influential BIM system which enhances capability to update, administer and design data for various stakeholders in the entire administration, design and construction segment of building life cycle. Really, Revit is a modeling system which has an influential database in BIM system. Furthermore, Revit is mainly utilized by contractors and designers for building operation. Indeed, Revit is important in building life cycle (BIM). In fact, Revit is a competent device in BIM that facilitate all data which concern building operation on condition that such structures are documented and modeled. BIM Execute Design Process According to Sebastian, design is normally a process where information is sequentially refined in succession stages or phases, each aiming at segment of a design (2010, p.10). Actually, every design process has particular questions and objectives which are normally handled before proceeding to other phases. Typically, a top-down method is preferred when moving from one stage another. The early phases aim at high-level policies of main effects which influence later phases. Moreover, the later stages aim at exploring and enhancing recognized objectives and accomplishing required task. BIM Managing Information Adoption of BIM devices generate opportunity that totally transforms and enhances design process in many ways. Though “BIM adopts the 2D-CAD design technique to enhance output of construction document stage, BIM design operation transforms its process in more effective manner through developing design information in the entire project stages” (Devuyst, Hens & De Lannoy, 2001, p.20). Indeed, BIM supports design team to analyze and assess output of their design at earlier phases of project. The early response enables fundamental and influential design policies to be enacted in the process. These give more possibility to form greater effects at affordable costs.
