The whole concept of BIM Modelling or BIM model has been accepted universally from building services community, architectural industry and structural engineering community because of its need to lean construction as well as its inter disciplinary uses. 3D Building Information Modelling has been in use since past few decades and is being adapted by the industry aggressively from embracing the new workflow of BIM processes. However, a lack of absolutely clarity is still being observed amongst homeowners regarding the result of Building information modelling, what needs to be achieved and how the concept may be used in the best possible manner.
Below are some of the beliefs regarding the usage of BIM? It throws some light on the use of the system, when it needs to be used and also by how much. For getting clarity, it becomes extremely important to understand the main difference between the non BIM CAD models as well as parametric BIM model.
Understanding 3D CAD models
The 3D CAD model is basically a virtual representation of the facility which offers visual details. The applications like AutoCAD MEP and AutoCAD architecture are used for creating 3D CAD model which may be used in designing, development, construction as well as for pre fabrication. On the contrary, a BIM Model is an intelligent model which his embedded with the parametric information which is very important for designing, development, construction, assembly, pre fabrication, analysis of the performance of energy as well as management of facility of the environment built.
For the BIM project, the details may be shared effectively between different stake holders, owners of the facility, architects, designers, MEO engineers, consultants, contractors, consultants, etc. Revit MEP as well as Revit architecture are the applications which are used for this type of modelling. Also the Nviswork system is used for detecting the fight between different system models.
Client’s actual needs vs. his stated needs
A crucial aspect which helps in deciding if BIM is needed or not is to gain a deep knowledge of the purpose of the model. Often, a difference has been observed between the stated needs of the client and his actual needs. In most of the cases, the clients stats their requirement for a BIM structure. But in reality what they need is simply a clash free 3D structure that could be used for extracting the respective construction drawing. In this type of a scenario, Auto CAD or AutoCAD MEP architecture may be used easily for providing a 3D model which fulfils the need. Alternatively, the BIM software may be used for providing the 3D structure without offering additional elements like data rich info.
In the other cases, the Fabrication Drawings may prove to be the actual base for planning, designing, construction and management of a specific facility. This scenario requires multidisciplinary stakeholders of the project for accessing BIM model in the lifecycle of the project at different levels. This, on the basis of the scope of the project, a fully developed BIM structure may have the requisite information like the dimensions of the elements of the building, the quantity take off information, requirements of the material, scheduling of time, cost, prefabrication data, stimulation of activity as well as energy performance.
