With GeoBIM, we have made it possible to access all saved geotechnical data in one and the same database via a web-based map interface. This allows everyone to have access to the same, updated and quality-assured information, so that you get an overall picture of all investigations that have been carried out and can download the data you need.
You obtain a ready overview that reduces the risk of carrying out investigations in locations that have already been surveyed, allowing you to save on important resources during the planning of future developments.
All data in the same 3D environment
The idea of bringing together all geotechnical data in the same database in an easily managed data format was conceived during work on the Helsingborg South Tunnel project around 2010. This involved having to interpret the combined results of a large number of investigations based on many different methods and saved in various data formats in order to produce the most reliable model of a complex geological environment.
The traditional procedure was to print out all results, maps and similar items onto paper and have them posted up on walls, rolled out on desks, projected onto screens, etc. The 3D visualisation was something you had to do yourself in your own head.
After some quite extensive manual jiggery-pokery with data formats, we managed to get all data into the same digital 3D environment. Geotechnical engineers, hydrogeologists and rock engineers could then interpret the combined results in a completely new way by running through the entire volume of data over and over again and enabling and disabling data so as to be able for focus on several parameters at a time. It was indeed possible – this had to be the future.
Database for the City of Helsingborg and the new hospital in Malmö
With financial backing from the Sven Tyrén Trust and the Swedish Research Council Formas, the GeoBIM project was created as part of the major TRUST 2013 R&D project, and development of the project got underway The GeoBIM concept has gradually been developed through cooperation with several ongoing projects to a point where now, in December 2016, it is being used for a number of major infrastructure projects, including the East Link (OLP4), the Cross-Connection, the North Bothnia railway line, the Varberg Tunnel and the European Spallation Source (ESS). We have also created an administration database for the City of Helsingborg and the new hospital in Malmö for the Skåne Region.
Enhanced hit rates save on resources
With GeoBIM, you get a closed digital chain extending from data collection in the field, via interpretation and production of a geological model including visualisation, to archiving and administration of all investigation data for future use. Because the interface with all data is accessed by logging onto a webpage, you do not need any software or licence on your own computer. As a result, all users always have access to exactly the same updated and quality-assured information. The tool ensures order and clarity of data, with all parties gaining quick and easy access to the same information. It can also easily be linked to all special programs used within the industry. The tool delivers optimum pre-requisites for planning, evaluation and interpretation of geotechnical data. GeoBIM increases hit rates and therefore the reliability of a geotechnical description of the construction engineering conditions below ground. It saves on resources throughout the entire chain, by having e.g. better positioned points for field investigations, optimum design of load-bearing structures and reduced handling of excavated masses.
