BUILDING INFORMATION MODELLING

Many consider Building Information Modelling(BIM) as a soft ware. Yes it is a software but it does more than. It is a process which applies to all aspects of the construction of a building, from the design, the estimating, the supply chain, the delivery of goods during the build process, the allocation of resources, the productivity requirements to meet targets and also in to the post handover phase through facility and assest management.

The people in the construction industry are falling short to understand the benefits of BIM and alleviate the process of construction industry in India. At my own previous job as an architect we were refrained to use BIM softwares. 

BIM is much more than just a detailed 3D model of a building. The accuracy of the model combined with animation fly throughs allow contractors to access the design layout before the building is built to make necessary alterations. This means that when the build takes place, there are fewer errors and far less rework needed. This moves the construction procurement process from design and build to design build by bringing the construction team in to the design process rather than them simply having to respond to a tender for construction after the design has been completed. 

Another aspect of BIM is the parametric design. What it means is that if you change or move the location of a wall, the elements attached to the wall will also move. Changing the number of windows will automatically change the quantity of materials required. This directly helps in cost estimations of the project. 

There are several 'D' associated with BIM software. Just in time delivery of materials requirement on site, estimation and cost aspects of building and sustainability targets to name a few. 

  

The planning of the project moves faster than anticipated by the use of BIM software. Hence it is very important to use in at every level in construction industry
