Introduction: Initial investigation highlighted potential savings of 4-11% in the Front End Engineering Design phase alone This proposal will move National Grid closer to realising the circa 20% (Her Majesty’s Government estimate) whole life cost and carbon saving associated with BIM; in particular through the design and construction project phases (4D, 5D and 6D BIM phases). Internal and external collaboration will continue to be at the heart of the trial with the sharing of intelligent 3D models and lessons learnt across National Grid and the wider gas industry.

At the heart of the proposal is the development of:

• A BIM Execution Strategy to make BIM business as usual;

• Policies, procedures & guidance notes e.g. model creation and key stage handover processes;

• Design & constructability assessment methodology;

Supplier (Principal Contractor & subcontractor) collaboration strategies and integration with current business practices.

Objectives:

To understand BIM techniques & tools and how they can add value to the way National Grid operates.

Expected Benefits: To further understand the potential cost savings across Gas project models in design and construction. The learning from this project will enable National Grid to make an informed decision on the deployment of BIM techniques & tools.
