We recognise the significant advantages that 3D computer modelling and the BIM process brings to the delivery of the design and construction process and asset management. Since 2007 we have actively integrated 3D modelling and BIM into our design delivery process.

The BIM process encourages forward thinking and smart use of building data. We integrate the design with delivery using an open BIM approach. The use of external third-party extensions and internal customisation improves the interoperability of software used by BG&E, allowing for flexibility and optimisation in the design process and the sharing of design data to external project teams. We have actively redefined internal workflows to take advantage of BIM, not only to design smarter and more efficiently, but to also improve project collaboration and communications involving all disciplines to minimise error and maximise quality.

Our experience has shown that the use of BIM improves the level of collaboration and coordination amongst the various disciplines involved in the design and construction stages of a project. This level of coordination and collaboration is increased further when the design team works on the same model. We have found that to maximise the benefits of BIM, the design process should be adjusted to suit with a greater amount of work carried out early on than on non-BIM project. BIM also allows other parties not involved in the design the opportunity to give input at early stages of the project. BG&E use this capability to aid contractors in such areas as construction sequencing, site logistics, preliminary quantities and material take-off, and to allow various options to suit the client’s needs.

By using BIM, we have achieved the following value-add benefits:

• A substantial increase in the designs team's ability to deliver accurate documentation on complex and a multi-discipline projects.
• Improved confidence in bills of quantities, material lists, etc. to assist with cost estimates.
• Higher efficiencies in the engineering cost to deliver a design due to the sharing of information.
• Increased constructability and reduced risk of any inaccuracies on the project.

• Co-ordinated timely delivery of design documentation and lower cost related to more accurate design, reduced duplication of work and better coordination.
• Improved whole-of-life cost savings throughout the asset management phase due to the availability of information regarding how things were designed, specified, built and maintained.
