Geovita and NGI have the pleasure of inviting you to part 3 in a series of webinars on BIM modelling for subsurface structures and ground conditions. 

The third webinar will focus on both environmental engineering and the design of ground improvement. First, there will be a presentation about how to build a 3D model for contaminated soil, which will estimate the volumes that must be removed. 

Second, there will be a presentation about how parametric design can optimize the design of ground improvement, and how one can use scripting and parametric design for building as-built models of the ground improvement.

Answers from Q&A BIM part 3:

  1. What version of Leapfrog do you use/recommend? Geo, Works?
    Leapfrog Works
  2. Looks great! Is it much work and are the clients willing to pay for it?
    The modelling work is not very time consuming, but with big areas and many boreholes the editing can take some time. However, in our experience, the same goes for other programs and making 2D maps. A benefit with Leapfrog Works is that it’s dynamic, so to add supplementary samples goes very smooth since the model automatically updates itself.

    Having a 3D model of the subsurface reduces uncertainties in the project and therefore the potential for unforeseen costs related to e.g. handling of contaminated soil. So far, the feedback from our clients and partners have been positive.

    To summarise: yes, we believe customers are willing to pay for this. Using a dynamic 3D-modelling software might even reduce costs later in the project life cycle.
