Elements are the digital prototype of the physical building elements such as walls, columns, windows, doors, stairs etc. that allow us to simulate the building and understand its behaviour in a computer environment way before the actual construction starts. Each model represents a snapshot of latest work respecting current state of development.
BIM enabled architect to use a bundle of product information and solutions within BIM library. With BIM it is able to reduce cost of providing information, offer quick response to clients with models more accurate than live material. It is an ability to lower project costs and improve design performance.
There are many ways to use BIM through design, construction, and facility management. The most important thing is to define what is critical to the specific project.
