Ground investigation data should be included in BIM models

Data from ground and site investigations should be included in BIM models to create a fuller picture.

Hewson associate director Paul Perry, speaking at this year’s GE’s basements and underground structures conference yesterday, said that the future for BIM was good, but only if the model is a real representation of the project.

Perry said: “The future of BIM is bright, but it needs to be polished up. There are too many picture and images of a project that can look real, but often they lack all the details.

“Geotechnical site mapping should be shown be attached to the BIM model. It is not rocket science, it is there to assist us.”

But the BIM model needs to be prepared by the right people, argued Perry, suggesting that an BIM technician could be guided by an engineer.

“Without the details of any pre-existing piles, foundations and even abandoned tower crane bases, the BIM model isn’t a real representation of what is actually there,” Perry said.

Perry suggested that the industry should be honest about temporary works that are left behind and ultimately become permanent part of the project, and not included in to the final BIM model.

“We need to look past the pictures that look good and have nothing behind them,” Perry added.
