Recent Advances in Bim in Geotechnics
Jim De Waele
The use of Building Information Modelling (BIM) is becoming more widespread throughout the various sectors and professions of the UK construction industry, however, in its "National BIM Report 2016", the National Building Specification (NBS) concluded that BIM was still a) "Far from embracing all parts of the supply chain" and b) "Not reaching the O&M phase of the building". Of course a positive step was taken when in April 2016 the UK Government departments were mandated to use collaborative 3D Level 2 BIM. However we still need more clients and the operators of constructed assets to follow the initiative, if we are going to improve upon the NBS’s findings. This paper examines two recent advances in BIM in the field of geotechnics. The first case study relates to the sharing of site generated data, that is gathered electronically on site, processed and then uploaded to the BIM model, all automatically. In this way, the stakeholders are seeing the object attributes updated in the integrated model in real time - as the work is done. The advantages of this process include the obvious savings in time and effort, avoiding mistakes, self-certification and the manifest openness that supports collaboration. The second case study relates to how monitoring data can be accessed from the BIM model. Whilst strictly not an “object” in BIM terminology, this information is important to the construction team during the building of the asset and surely to the operator and maintainer too. The monitoring database provides a way of all parties being able to interrogate the same data, both in real time and historically. This information truly spans between design, construction and the O&M phase, and has the potential to bridge some of the traditional gaps. Both advances support the wider uptake of BIM and its continuing development. More importantly, in the author’s view, both give further impetus to the changing landscape of construction procurement and the way that the industry works. If we are to continue to improve the efficiency and effectiveness of the construction industry we must learn to collaborate and digitalise. The author believes that BIM has the power to deliver this, almost by default, encouraging and cajoling the parties to act in this way.
