A Comprehensive BIM Glossary for Manufacturers and Specifiers

3D Modelling - A computerised process of developing a digital representation of a building or any physical asset in three dimensions.

4D Scheduling - The process of integrating BIM data with project schedules.

As-built Model - A BIM model that reflects the actual construction of a building or facility, capturing any deviations from the original design.

BIM - Building Information Modelling is an advanced technology that allows the creation of a digital model of a building or structure, complete with its physical and functional attributes.

BIM Object - A digital representation of building components or systems designed to be incorporated into a larger BIM model.

Clash Detection and Resolution - Identifying and resolving conflicts between building elements in a BIM model.

Classification - The categorisation of a BIM object according to a defined classification system, such as UniClass or Omniclass.

Classification System - A system for categorising building elements in a BIM model.

COBie - Construction Operations Building Information Exchange is a standard format for exchanging building information data, including BIM objects.

Compatibility - The ability of a BIM object to work seamlessly with other BIM objects and software programs.

Data Exchange - The process of sharing BIM data between different software programs and systems.

Federated Model - A BIM model that combines multiple discipline-specific models.

Geometry - The shape and size of a BIM object, defined by mathematical equations and algorithms.

IFC (Industry Foundation Classes) - A standardised file format for exchanging BIM data.

Laser Scanning - The process of capturing existing building data for use in a BIM model.

LOD Specification - A document that defines the development level required for each BIM model element.

Manufacturer Data - Information about the manufacturer of a BIM object, such as contact details, product codes, and technical support.

Material Properties - The characteristics of a material used in a BIM object, such as colour, texture, strength, and durability.

Parametric Modeling - A type of modelling that uses parameters to define and manipulate elements in a BIM model.

Performance Characteristics - The functional properties of a BIM object, such as acoustic performance, fire resistance, and thermal conductivity.

Point Cloud - A set of data points that represent the geometry of a building or facility.

Product Data - Information about the specific product represented by a BIM object, such as dimensions, weight, and installation instructions.

Quantity Surveying and Takeoff - Two processes that work together to estimate the cost of construction using BIM data.

Quantity Takeoff - Measuring and quantifying materials and components in a BIM model.

Revit Family - A collection of BIM objects with similar properties and behaviours in a BIM model created using Revit software.

Solibri - A software program for model checking and coordination in BIM projects.

Sustainability Analysis - The process of evaluating the environmental impact of a building or facility by analysing BIM data.

Template - A predefined set of settings and parameters used to create a new BIM object.

Virtual Design and Construction (VDC) - The use of BIM technology to create a virtual model of a building or structure and simulate its construction process.

Visualisation - Creating 2D or 3D representations of a BIM object for communication and presentation purposes.

Workset - A subset of a BIM model that can be worked on independently by a team member.
