Constructing of a Building is not a single step process. Entire process involves quite a long process and the entire project is divided into different phases with different Engineers from different facet working under the same umbrella. Structural Engineer typically investigates the basic requirements for a building to be constructed. Right from evaluating the soil condition of the foundation, providing the size and location of the underground utilities to coordinating with various engineers for related purposes. The Electrical engineer further institutes the building’s total power requirements along with designing the circuitry etc. MEP Engineers on their part designs the plumbing, heating, ventilating and air conditioning (HVAC) along with taking responsibility of designing incoming underground utilities. The Landscape Architect adds a dash by taking care of designing exteriors and interiors along with designing the contours of the property.
In this entire process, apparently as they work independently there are times when the Mechanical Engineer, Structural Engineer, Electrical Engineer or anyone involved in the above mentioned Building Construction process often gets stuck or there can be innumerable clashes and errors due to missing co-ordination. Building Information Modeling acts as a great tool at this juncture. It acts as a tool to help drafting services coordinate various stages of a project, all integrated into one single model with multiple interface. This means that it makes it possible to virtually visualize how a building will function post construction.
Building Information Model (BIM) is the latest application of computer imagery in the field of architecture. After creating the 3D Model of the proposed building, it is further passed onto various design consultants for their review and comments. The final product rules out some of the problems related with the more conventional methodology of Computer Aided Design (CAD) and ascertain that everything fits into its stipulated space and schedule. With the help of BIM Services the Virtual Model is created keeping in mind all the future requirements. This reduces the risk of any conflicts within various ongoing works done by different workmen at different point in time.
Typically, the 3D model can be rotated on the axis, and when MEP Modelers work on Plumbing or HVAC Segment they might face some conflicts with respect to the allotted space and thereby they adjust the systems accordingly.
With the addition of the fourth dimension i.e. ‘Time’, BIM can generate a virtual construction schedule that diagrammatically represents a particular building evolving from foundation all the way to completion. This virtual construction schedule is very effective when used as a mean to evaluate the project progress regularly during the construction meetings. Hence, for ongoing projects in the site, one can compare the status of the construction with the BIM imagery or the diagrammatic schedule.
Currently, BIM seems to be cost effective only for large projects, however, the day is not too far w
