Building Information Modeling and Its Benefits

Building Information Modeling (BIM) is a methodology for which National Building Information Model Standard Project Committee has given a definition-

''Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition.''

In other words it can be said that Building Information Modeling is the digital model made by collaborative efforts of contractors, engineers and architects etc. incorporating all the design details, characteristics, and decisions. In the 3D model produced here, the objects like walls, doors, windows etc. are defined parametrically where all these entities show spatial relationship with each other. If one entity is amended, parameters of others are automatically changed accordingly.

Instead of providing 3D model which can be rotated in all the directions enabling the building to view from all the angles, it also provides information about light analysis, geographic information as well as quantities and properties of the building components. It also helps models to generate constructability reports, cost estimate, coordinate, plan, and schedule etc.

Benefits of Building Information Model (BIM)

It enables energy analysis, structural analysis, accurate quantity and schedule analysis etc. while making the model resulting in reduction of waste and improvement in scheduling. In other words it enables Architect, Structural Engineer, Construction Manager, Service Engineer, Quantity Surveyor and client to work together before starting the actual construction of the building in order to avoid the conflicts at early stage otherwise it could have been detrimental.

This also helps to make alterations at the time of making the model by analyzing all the aspects which are required for constructing a building like HVAC, MEP, material, architecture etc. Otherwise, this will evolve as an interruption while constructing the building. Moreover, the greatest benefit that can be availed through Building Information Modeling is that the cost repercussions are very little or zero. Resolving all the problems that might occur at the time of construction of the building proves to be an impetus ensuring hassle free accomplishment of the task.
