Why is subsurface knowledge so critical? Canada, September 20th 2018 BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
sharing Why is subsurface knowledge so critical? Paris, November 1st 2017 There was - no complete data of existing underground infrastructures - no sharing of data about previous boreholes made for the construction of RER - No « easy access » to groundwater data A need to share in an « urban platform » • geological, geotechnical, hydrogeological data • 3D underground cadaster Who will be in charge ? BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
Why is it (so) difficult to merge modelling of built environment and “geology” ? Built environment “Geology” Modelling process Complete design by human Progressive exploration, and understanding (increasing complexity) Data acquisition Relatively cheap (Lidar…) Expensive and ”indirect” Modelling tools CAD engineering software “ geomodellers ” (interpolation algorithms) Standards BIM For 2d : GeoSciML CityGML For 3D ??? Accuracy / uncertainty Usualy well known (design – Difficult to estimate, construction) communicate, and represent Visualisation VR tools for general public “for experts only” People Engineers Natural scientists > 4 BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
2 crucial components for dialog / co-operation ? 1. A partnership framework • a law (i.e. Key Registries) • or a collaborative framework • public-private partnership 2. Standards… • to share within and across communities • but not multiple standards… • to be implemented in professional software • not one standard per country (international players) • facilitate sharing of best practices • developed from professional users requirements BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
1 - A collaborative framework INTERESTS OF THE PARTIES IN A MULTITIER PARTNERSHIP Party Role Contributes Benefits State / ministry Legal framework Optimal use of public goods Local authority Owner Implements obligations to collect Optimise costs data in contracts with private / Reduce risks public contractors Better planning Engineering / drilling Data "creator" Provides data in appropriate format Access to data from all parties company No need to archive its data Constructing company / User Provides data in appropriate format Access to data along life of operator of infrastructure construction / exploitation IT infrastructure provider IT operator Provides secure and trusted access Long terme contracts (public / private) to services Software provider Tech provider Tools for data management and Long term contracts processing Innovation labs Innovator Creation of added value products Integration in ecosystem Geological survey Trusted party Provides reference rules Collects maximum of for geology (sl) Data custodian/ harmonize data information Develop services BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
2 - ABOUT STANDARDS : Some … current / parallel initiatives Standard ISO 19156 Observation & Measurements (formally OGC) standard offers a generic template to link observation processes, conditions and results. ISO TC182 formalize several standards for geotechnical tests and analysis The GeoScience Domain Working Group from OGC and IUGS launched a Borehole Interoperability Experiment that aims at harmonizing existing standards for borehole and associated data description The Underground Infrastructure Pilot proposes a Model for Underground Data Definition and Integration (MUDDI) bSI Common Schema Project on geotechnics BRO: the Dutch Key Register of the Subsurface: standardizing public information on the subsurface In France MINnD UC8-GT working group focus on Geotechnics In Germany, the Federal Waterways Engineering and Research Institute launched a project for geotechnical data standardization AGS is a very used format for geotechnical tests and analysis description. It is particularly used in the UK / Commonwealth. Project DIGGS was an attempt to propose AGS data in a XML compliant format Europe-wide geotechnical, geological and site conditions inventory, collecting and harmonizing national/regional data-bases BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
OGC GeoScience Domain Working Group in a nutschell • Joint Domain Working group between OGC and CGI-IUGS • A forum to enhance and organize geoscience data standardization • Initial focus : • borehole Interoperabilty Experiment • 3D geological model • First meeting in Southampton OGC TC (September 2017) • Co-chairs : Carina Kemp (GeoScience Australia) + Mickaël Beaufils (BRGM) BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
GeoScience DWG position in OGC world • Main targets: – Harmonize geoscience data expression and facilitate usage – Stay connected and even propose enhancements to technologies / solutions – Connect people interested in the geoscience topic – Ensure proper connections with other groups / communities inside and outside OGC Volcanology Agriculture oriented Technology oriented WG WG Mineral Seismology resources Soil GeoScience DWG Geology Climate oriented WG Oil & gas Mining City & infrastructure oriented WG Geophysics Hydrology oriented HydroGeology Underground WG constructions BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
The MINnD initiative in France - A French consortium of 71 partners 1 goal : enhancing BIM capabilities for infrastructure modeling and management (complete lifecycle of infrastructures) BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
Starting from a use case • MINnD UC8 : Underground Infrastructures (mid 2017-2018) • Standardization of Underground Infrastructure description and its environment (geotechnics) • Reusing and extending existing standards • Concrete applications / feedback • Lyon-Turin (rail) • Grand Paris Express (rail) • CIGEO project • Long term and deep storage of radioactive waste • Several connected tunnels BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
Upcoming event for geotechnical data • Joint bSI – OGC workshop for geotechnical data standardization • Share of knowledge on that topic • Alignment of initiatives and standard programs • Sponsored by Geotechnical Data Standardization Workshop Maison de la Géologie, Paris V January 22 – 24, 2019 BRGM THE FRENCH GEOLOGICAL SURVEY WWW.BRGM.EU
