BIM – A new visual interactive modelling for construction
Building Information Modelling (BIM) is one of the most promising developments in the Architecture, Engineering and Construction (AEC) industries. BIM simulates the construction modelling and project in a virtual environment. An accurate virtual model of a building is digitally constructed with BIM technology. When completed, the computer-generated construction model contains precise geometry and relevant data needed to support the construction, fabrication and procurement activities required to complete the building structure.
BIM offers the potential to decrease project cost, increase productivity and quality, and reduce project delivery time that the Architecture, Engineering and Construction (AEC) industries are looking for. BIM represents the development and use of computer-generated n-dimensional (n-D) models to simulate the planning, design, construction and operation of a facility and helps architects, engineers and constructors to visualise what is to be built in a simulated environment and to identify potential design, construction or operational issues. It is important to note that a building information model characterises the geometry, spatial relationships, geographic information, quantities and properties of building elements, cost estimates, material inventories and project schedule.
The principal difference between BIM and conventional 3D CAD is that the latter describes a building by independent 3D views such as plans, sections and elevations, in contrast to the intelligent contextual semantic of BIM models, where objects are defined in terms of building elements and systems such as spaces, walls, beams and columns. Building Information Modelling (BIM) has emerged as an innovative way for construction modelling and to manage projects.
Revit technology is one of BIM software that helps architecture, engineering, and construction (AEC) teams create high-quality buildings and infrastructure. Revit technology helps to model shapes, structures, and systems in 3D with parametric accuracy, precision, and ease. It completely assists with streamline documentation work, with instant revisions to plans, elevations, schedules, and sections as projects change Revit technology is used to coordinate all data inputs (including CAD) and produce federated project deliverables. Both programs are often used within the same firm, with BIM and CAD specialists working on different elements of a project.
Many researchers and practitioners have indicated that the BIM technology is set to become indispensable to building design and construction. As the use of BIM accelerates, collaboration within project teams should increase, leading to improved profitability, reduced costs, better time management and improved customer/client relationships. The teams implementing BIM should be very careful about the legal pitfalls such as data ownership associated with propriety issues and risk-sharing.
