[FULL] Technical Seminar: BIM Modelling of Underground Utilities and Boreholes

Date, time & venue 
2019-03-06;18:30pm – 20:00pm;Lecture Theatre N002, The Hong Kong Polytechnic University 


Programme Highlight

The speaker will describe the UK Project Iceberg (2015-17) and its conclusion on the data collection, management and sharing of underground information that include underground utilities (UU) and boreholes among others. One of the findings was that the AGS data format developed in 1992 by the Association of Geotechnical and Geoenvironmental Specialists enabled sharing of GI data across the construction sector. The speaker will discuss the problems in using the AGS file for modelling or storage of boreholes and demonstrate a new and easy way on how to import, store borehole data and to create model in CAD and BIM platforms using big data format. For underground utilities, the focus is the positional accuracy rather than the BIM presentation. Modelling for 3 typical usages on utility data collection, new utility proposal and asset management will be shown. The speaker will discuss the world-wide trend on the 3D modelling of UU during various stages of development of a new project. The final part of the seminar will be the paradigm shift of BIM from Building Information Modelling to (Building) Information Management according to the just-released ISO19650-1&2:2018 Organization and digitisation of information for buildings and civil engineering works, including BIM -  Information management using BIM.
