We have been delivering projects in computerised 3D environments since the early 1980s. Today we use Building Information Modelling (BIM) to create a multidimensional intelligent model of a project, building or site.

By including time, cost and maintenance information (the 4D, 5D and 6D ‘dimensions’) in a BIM model, we can use it as a decision-making tool to help reduce risk throughout the project’s design, construction and operation phases.

A complete model allows opportunities and problems to be identified early, saving money, time and waste across all stages of project delivery.

It also allows users to visualise the completed project, calculate project costs more accurately and plan ongoing maintenance upon completion.

BIM dimensions

3D – Clash: Multidiscipline design model enables clash detection ensuring “right first time” delivery

4D – Time: The programme is linked to the model allowing visualisations and optimisation of the construction sequence

5D – Cost: 5D BIM links the BIM model to underlying cost data in such a way that any change in the design is reflected in the budget immediately

6D – Maintenance: 6D BIM refers to the intelligent linking of individual 3D model components or assemblies of the building model with all of the information required to enable customers to manage each asset for the whole of the asset life.
