WHAT IS BIM
Building Information Modelling, BIM is one of the most promising recent developments in the architecture, engineering, and construction (AEC) industry. BIM uses a digital model that incorporates information and parameters related to building form, structure, and systems. When completed, the building information model contains precise geometry and relevant data required to support the design, procurement, fabrication, and construction activities necessary to realize the building. After completion, the digital model can be used for building management.
BIM DEFINITIONS
There is no universally accepted definition of BIM. In the construction market, there are various definitions of BIM from different organizations and institutes. The reason there is no accepted definition is that BIM is ever-evolving; however, there have been some useful definitions, some of which are provided here.
"Building Information Modelling (BIM) is a set of technologies, processes, and policies enabling multiple stakeholders to collaboratively design, construct and operate a Facility in virtual space. As a term, BIM has grown tremendously over the years and is now the 'current expression of digital innovation' across the construction industry".
ΒΙΜ DICTIONARY
"Building Information Modeling is a digital representation of physical and functional characteristics of a facility creating a shared knowledge resource for information about it forming a reliable basis for decisions during its life cycle, from earliest conception to demolition. "
RIBA
"Building Information Modeling (BIM) is an intelligent 3D model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructure".

WHAT IS BIM
BIM FOR ARCHITECTS
Using BIM models, architects can effectively communicate with the client through the precision of the 3D visuals. BIM tools allow designers to explore design options and make informed decisions based on data-based insights. Cloud collaboration enables architects and extended team members to work in real-time update models and reduce errors in later construction stages.
BIM FOR STRUCTURAL ENGINEERS
A rich data model allows engineers to address competing design parameters, quickly test the viability and structural integrity of different options early in the design phase, and easily adjust structural models based on design changes. Model-based collaboration improves communication between structural engineers and the extended project team.
BIM FOR MECHANICAL ENGINEERS
MEP designers and detailers can explore the best constructible design of building systems before settling on a decision. They can also take advantage of design calculations to optimize systems and fabrication content to derive optimal layouts. Working in BIM, mechanical engineers and detailers can convert a design intent model into a detailed fabrication model ready for shop drawings, procurement, ductwork manufacture, and installation.
