WHAT IS BIM ?

WHAT ARE ITS BENEFITS TO THE CONSTRUCTION

INDUSTRY?

BIM/BIMsBuilding Information Modelling (BIM) – 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 demolitionBuilding Information Models (BIMs) – the output of the BIM process; digital files that describe every aspect of the project that support decision-making throughout a project cycle

BIM Objects

Vague and undefined, generic or product-specific, solid shapes or void-space oriented (like the shape of a room), that carry their geometry, relations and attributes; also parameters and relations to other objects

BIM Design Tools

Extract different views from a model

THE 5D MODEL AND VARIOUS DIMENSIONS

5-D Functionality can integrate design, cost, and schedule in 3-D output.Building Information Modeling (BIM) is a digital representative of physical and

functional characteristics of a project, forming a reliable basis for decisions during the project’s life cycle

Element of a 3-D model are linked to the execution schedule

Information that can be embedded in 3-D model:• Geometry• Spatial data (from

geographic information system/lidar)

• Specifications• Aesthetics ( eg, Color )• Thermal properties• Acoustic properties

Element of a 3-D model are used to develop budget and linked to cost heads

Improved visualization

Improved productivity via easy information retrieval.

Increased coordination of construction documents

Linked vital information such as vendors for specific materials, location of details and quantities required for estimation and tendering.

Increased speed of delivery.

Reduced overall costs
