Dimensions of BIM implementation – global perspective
What do these BIM dimensions mean?BIMPanzee (2013) define these BIM Dimensions as follows:
3D BIM3D BIM is the initial BIM phase, it is about creating 3D graphical information and adding non-graphical data to the model. Here, all disciplines work collaboratively contributing towards the model.The benefits of 3D are better visualisation for all project team members, spatial coordination, fewer errors and the ability to share up-to-date information between all project parties.BIM 3D models assist contractors in the programming and scheduling of BIM projects, using semi-automated processes. This is achieved by adding programme and time data to a BIM project. A 3D BIM model can be interrogated and analysed within various energy analysis software packages, such as SunCast and Daylight Analysis.

5D BIMThis level concerns the use of BIM for quantity schedules and costing information and helps quantity surveyors and designers to produce accurate costings of building projects.Various software can be used to assist in the production of quantity take-offs and cost information, such as Revit and NBS Create.Standardised data can then be integrated into BIM models, ensuring that building components meet the required regulations.This information can be accessed from the BIM core model and BIM package.
6D BIM6D BIM is best explained by this quote from BIMPanzee:
6D BIM (sixth-dimensional building information modelling) helps perform energy consumption analyses. The utilization of 6D BIM technology can result in more complete and accurate energy estimates earlier in the design process. It also allows for measurement and verification during building occupation, and improved processes for gathering lessons learned in high performance facilities. Integrating BIM with 6D CAD simulation models leads to an overall reduction in energy consumption.(BIMPanzee 2013)
- Soft landings: ‘A strategy adopted to ensure the transition from construction to occupation is bump-free and that operational performance is optimised’ (designingbuildings.co.uk 2015).
- Construction Operations Building Information Exchange (COBIE): According to the NBS, ‘COBie is a non-proprietary data format for the publication of a subset of building information models, focussed on delivering asset data as distinct from geometric information’ (Hamil 2018).
- As-built models: BIM models including graphical and non-graphical information about the project as it was built. Another term for it is ‘as-constructed’ and provides information to clients, asset and facility management, beneficial for the future use of the asset.
- Bespoke data on installed systems: In certain cases, where suitable off-shelf data for installed systems is not available or is not available in a meaningful manner, a bespoke database may be written.
- Whole-life data: This is information detailing all phases of a building’s lifecycle, from initial brief and design to demolition and removal of debris.
