BIM or Building Information Modeling has been around for decades. But in recent years, it has become quite popular with professionals in the fields of architecture, engineering, and construction.
BIM has multiple dimensions. Each of its dimension can be related to the aspects of designing, planning, and construction. In India, BIM or Building Information Modeling is increasing its popularity as more and more professionals are turning towards BIM authoring software to use it into their projects
What exactly is BIM?
Building Information Modeling is a process in which a 3D model is developed for buildings and infrastructures. It is quite useful for designers and professionals as it helps them to gain key insights in efficiently planning, designing, and executing their construction projects based on 3D modelling. Using BIM, the designers can virtually build the building or infrastructure on a computer before the project is actually built. 3D objects represents the most accurate data which can be used for analyzing daily construction activities, coordination among different building services, time analysis, cost analysis, etc. Read more here.
Subsets of BIM
There are various subsets of BIM called dimensions.
3D is the object’s three-dimensional model itself
Here, existing onsite conditions such as the topography of land can be taken into consideration as well as the design and aesthetics of the model. It can also be used to present walkthroughs and animations of the building to potential clients.
The 4D model then expands upon the project’s schedule
It can simulate different phases of the project as a visual and guarantee the project’s completion in a timely manner. It also adds information as the project progresses to keep track and project future trends.
5D links cost estimation with the rest of the model
It estimates the costs of various components and materials. It is highly valued by cost managers. This dimension gives the planners an idea of what they are spending, how much capital they need and even if there is a more feasible option. It can help allocate budget for various branches of a building- for its plumbing, equipment rooms etc.
6D deals with sustainability
It allows professionals to be eco-conscious when designing their model and offers them sustainable alternatives to use in their project.
7D represents management
It shows how the project can be operated, right down to the entirety of its life cycle. It can provide maintenance and technical support plans. Description and details of engineering materials can also be added at this stage in relation to the type of model being built. This can create a facilities management database that makes the model even more accurate.
And finally, there is 8D which deals with safety- how well the structure can cope if a natural or human-made calamity were to occur, the necessary precautions and plans to minimize damage. This may include evacuation plans, fire exits, and escape routes. It may also be used to prevent any onsite hazards during construction by revising and eliminating any risk factors.
For now, these are the widely used dimensions in BIM software, but as its use expands, more dimensions are expected to pop up, dealing with various other factors that come with the construction and planning of a project.
Benefits of BIM
The BIM software makes cost estimation very easy. It helps planners predict and estimate the total cost of their project, from beginning to end, along with the exact quantity of the material required. This helps save money and lowers the cost of the overall project. Additionally, alternate options are presented to professionals to allow them to make their own decision on how much to spend on a specific part of the model.
The BIM software links all aspects of designing, planning, and construction. This enables an efficient collaboration between the team- from the technician to the architect to the structural engineer and more. Because the entire model, along with its life cycle and materials, is on a cloud, multiple copies of the same design do not have to made or remade depending on changes. The entire team can work on the model together, saving time and avoiding confusion. This can save time and avoid any mismanagement from taking place.
Visualization and Simulation
The 3-D model shows the result of the project even before construction has begun. Detailed floor plans and structure designs can be used to show clients what they are paying for; This helps stimulate funding as the simulation can be run showing the on-time delivery of the product. Clients can rely on the 3-D model as it takes every bit of detail into consideration.
A great advantage of the BIM software is its projection of any future event such as an onsite hazard or disaster. With the help of the simulation, planners can review their design multiple times and reduce any risks as well as add safeguards to prevent them.
Popularity in India
Looking at its many benefits, it is really no surprise that the #BIM software is gaining momentum in #India. As a growing population and economy, the BIM software- also called VDC, short for Visual Design and Construction, in India- is very efficient to use in the construction industry. As competition increases, companies turn to more sophisticated and modern methods for designing to keep up. A survey conducted by J.V. Kumar and M. Mukherjee in their research article. The scope of Building Information Modelling(BIM) in India (2009), reveals that 81% of companies use BIM for efficiency and/or process improvement while 9% companies use it as their owners demand it and only 4% use it because their competitors are using it.
Reasons for using the BIM software range from competitive advantage to cost efficiency to the clientele demand, signifying a technological change. The study also shows that 23% companies already use BIM while 23% are interested in using it and 30% are either in the process of testing or adopting BIM. The BIM users are overall satisfied with the software, and the support for it continues to grow.

The BIM software is revolutionizing the way infrastructure built, designed and constructed. Until recently, it was used by developed nations, but now, due to its appeal and advantages, even developing countries have begun to use it. In India, the BIM software is particularly of use as it caters to the demand and ensures efficient use of resources in an economy that becomes more competitive every day.
