HS2 is trialling a new artificial intelligence tool that will help it reduce its carbon footprint.

The new AI technology, which will support carbon and cost estimation, is being trialled on a number of HS2 sites managed by the Skanska Costain Strabag joint venture.

The tool automates the BIM process so that different design options can be simulated using different types and quantities of construction materials.

This means carbon emissions and environmental impacts of construction can be visualised, measured and compared, resulting in the design of more environmentally-friendly solutions.

The new tool, which is being developed by Skanska as part of a project funded through Innovate UK, is an innovation which will replace the current method of manually measuring 3D drawings, and will assist the design process in reducing carbon emissions throughout the life of a building.

Skanska is leading the project, working with software developer Nomitech, Mott MacDonald, the Manufacturing Technology Centre (MTC Data and AI Research), RICS and HS2.

It is designed to lead to shorter pre-construction phases, reduced project management costs, greater visibility of carbon emissions and overall improved cost and carbon control.

The project will also develop industry best practice for estimation and cost management.
