What do you understand by the additional dimensions which are added on BIM models?

Do you want to understand the growth and progress which has been made by BuildingInformation Modeling in the last one and a half decade?  The journey of BIM has been full of innovations and revolutions since the time it got introduced to Architecture, Engineering and Construction industry as over the years experts have been successful in finding and adding new dimensions to them.  In the beginning when architects, engineers and contractors realized that BIM can be utilized by them for efficient execution of construction projects, they actually did not know that it can be so much helpful for them. Though they had an idea that BIM is going to prove important for them but they did not know that it will completely revolutionize the methodologies which had been used so far for carrying out construction.

BIM has a huge impact on the way design and construction professionals used to create architectural, structural and MEP design in preconstruction phase. Earlier huge efforts were required from the side of architects, engineers and drafters during design documentation as they had to develop handmade 2D technical drawings for representing different parts of architectural, structural and MEP design.  In the absence of sophisticated digital tools, tools such as paper and pencil along with instruments such as compass and protractor used to be optimized for developing technical drawings by drafters earlier.

The uses of Building Information Modeling by architects, engineers and technicians for representing building design through a model-based design approach is effectively embraced by the industry since it has many important advantages for all those involved in building process.

Drawings which used to be developed earlier could only speak about the design of the building and were unable to represent other important information that is required by design and construction professionals.  BIM models containing 4D, 5D and 6D in them which are individually developed for architecture, structure and MEP can provide comprehensive information on design, construction, accurate materials and quantity takeoffs etc. This information is important for gaining better outcomes from the project.
