Why is subsurface knowledge so critical?

Why is subsurface knowledge so critical?

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 ?

sharing

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 CityGML For 2d : GeoSciML For 3D ??? Accuracy / uncertainty Usualy well known (design – construction) Difficult to estimate, communicate, and represent Visualisation VR tools for general public “for experts only” People Engineers Natural scientists

2 crucial components for dialog / co-operation ?

• 1. A partnership framework
• a law (i.e. Key Registries)
• r 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

Party Role Contributes Benefits State / ministry Legal framework Optimal use of public goods Local authority Owner Implements obligations to collect data in contracts with private / public contractors Optimise costs Reduce risks Better planning Engineering / drilling company Data "creator" Provides data in appropriate format Access to data from all parties No need to archive its data Constructing company /

• perator of infrastructure

User Provides data in appropriate format Access to data along life of construction / exploitation IT infrastructure provider (public / private) IT operator Provides secure and trusted access to services Long terme contracts Software provider Tech provider Tools for data management and processing Long term contracts Innovation labs Innovator Creation of added value products Integration in ecosystem Geological survey Trusted party for geology (sl) Provides reference rules Data custodian/ harmonize data Collects maximum of information Develop services

1 - A collaborative framework

INTERESTS OF THE PARTIES IN A MULTITIER PARTNERSHIP

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

2 - ABOUT STANDARDS : Some… current / parallel initiatives

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)

GeoScience DWG Hydrology oriented WG Agriculture oriented WG City & infrastructure

• riented WG

Climate

• riented WG

Technology oriented WG

• 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

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
