Geotechnics still unconvinced by BIM

bim 2by3

Work remains to be done to convince people of the need for building information modelling of the ground beneath construction projects, a key engineering figure has warned.

Chris Hurst, principal geotechnical engineer at engineering consultant Mott MacDonald, said there were a number of challenges to overcome before ‘geoBIM’ became widespread.

Speaking at the Ground Engineering Infrastructure Summit in London this afternoon, Hurst said the importance of understanding ground conditions fully was not always recognised.

“There is a lack of awareness of ground risk issues throughout the supply chain,” he said. “It is also not recognised how geoBIM could offset this risk.

“We are often told geotechnical models are not required but I believe we have a strong case for models on all projects.”

He added: “GeoBIM should be the foundation of all BIM models.

“People understand projects better in 3D; it is hard to understand geology in two dimensions.”
