What is BIM?
Building Information Modeling (BIM) is a digital representation of a facility's physical and functional characteristics that supports decision-making throughout its life cycle. It includes various dimensions, such as 3D visualization and integration of design, cost, and scheduling, leading to improved coordination, productivity, and reduced costs in the construction industry. BIM also facilitates sustainable practices and efficient facility management through detailed data extraction and maintenance planning.

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 demolition Building 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 03

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
