BIM is a collaborative method of working using one digital model which everyone can view and understand.
It is a means by which information can be modelled and managed in a team environment and one in which all team members should work to the same standards.
This means all of the information about the building and every component in that building is available in one place. It’s a system which aims to go beyond simple production of construction information but rather one which encompasses the whole process from concept to construction to completion and ultimately building use. One major benefit being that different aspects of the design can be easily co-ordinated and integrated leading to faster production, less mistakes and ultimately, cost saving.
