Significance of Building Information Modelling
BIM which refers to building information modelling is a technique that has been adopted in the AEC industry that helps to plan and manage projects effectively. During the design process, BIM facilitates creation of digital representations of buildings by using geometry and relevant data. Utilization of software tools is one of the benefits that AEC industries have earned by using BIM technology in its operations. BIM also helps to improve the operability between construction teams, effective coordination of construction projects as well as better scheduling. A virtual information is created by the design team which consists of engineers, surveyors as well as architects who later on pass the model to contractors who implement the design. Even before moving to the site of construction, the design team is able to get a virtual construction model of the project.
BIM helps to provide high quality as well as accurate documentation of the construction process. The building lifecycle is also significantly minimized in order to increase the level of interaction between architects, contractors as well as engineers. BIM has also helped in coordination of the various processes involved in the building lifecycle hence eliminating any conflicts that may arise between experts. Besides production of accurate quantity take-offs, BIM also helps to provide improved construction management during the entire process. Implementing BIM during the design process leads to a more cost-effective project.
With the help of BIM, the 3D objects of the design can be analyzed by the computer in order to identify any errors and correct them automatically thus making this technology more superior as compared to manual drawings. There is a significant reduction in number of errors and change orders with the help of this technology. During cost estimation and placing orders for materials, contractors use the data provided by BIM to generate bills for the materials. Building models therefore allow integration of most processes involved in a construction project.
BIM tools differ from those used in CADD. BIM mostly involves online simulation of a construction model and the processes provide better products at a much cheaper cost to owners. This technology is characterized by use of coordinated computable information on a building project during design as well as construction. Creation of the model enhances better decision making, construction planning, performance predictions as well as cost estimates. This kind of technology is usually implemented during the entire building life cycle which includes the maintenance and operation stages.
In order to minimize the design lifecycle, BIM technology enables creation of different components of construction prior to its implementation. BIM also plays a huge part when it comes to cutting project costs simply by eliminating wastage of construction material.
