ABOUT BIM…
► Building Information Modelling (BIM) is a digital representation of physical and functional characteristics of a facility. A building information model is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition.
► Originally used for building, now largely used for large infrastructures (highway, metro, airport…) (over 50% of BIM projects in France)
► Standards developed by BSI consortium

EU SUPPORT
A French collaborative research project► Interoperable Information Model for Sustainable
Infrastructures► A French consortium of 60 partners► 1 goal : enhancing BIM capabilities for
infrastructure modeling and management (complete lifecycle of infrastructures)

THE MINND PROJECT
MINND OBJECTIVES
date
►Progress in the modeling of different forms of representation and evolution of objects in their spatial and social environment
Control and share information about infrastructures
Improve productivity and competitiveness
“Control” risks
Implement projects in the context of sustainable development
THE FRENCH GEOLOGICAL SURVEY
THE BRGM IS FRANCE’S LEADING PUBLIC INSTITUTION WORKING IN EARTH SCIENCE APPLICATIONSFOR THE MANAGEMENT OF SURFACE AND SUBSURFACE RESOURCESAND RISKS.
ITS ACTIVITIES ARE GEAREDTO SCIENTIFIC RESEARCH, SUPPORT TO PUBLIC POLICY DEVELOPMENT AND INTERNATIONAL COOPERATION.
UNDERSTANDINGgeological phenomena and associated risks.
DEVELOPINGnew methodologies and techniques.
PRODUCINGand disseminating data to supportthe management of soils, subsoilsand their resources.
DELIVERINGthe necessary tools for managing soils,subsoils and their resources, preventing risksand pollution and developingclimate change policies.
Over
1000 staffincluding more than 700 engineers and researchers
WHY ARE WE (BRGM) HERE ?
► Our infrastructures and cities are not laying on a flying carpet…
KEY CHALLENGES FOR SMART / SUSTAINABLE / RESILIENT CITIES AND INFRASTRUCTURES DEPENDENT OFSUBSURFACE KNOWLEDGE
► Geo-Hazards : ground stability, subsidence, earthquake, flooding
► Resources / services : water, geothermal energy, energy storage, building materials
► Remediation of polluted soils, urban wastelands…
► In the context of climate change and energy transition
► and of increasing conflict of usage of the underground
We need an holistic modelling of cities that integrates the subsurface (and the other components of the natural environment as air, water, biodiversity)
Geological surveys, environmental agencies are information providers and data custodians
Inspire is supposed to provide this type of information about environment from public
organisations…
HOWEVER, THERE ARE ALREADY EXAMPLES / EXPERIMENTS …
► But without shared best practices, common standards and real “integration” in current urban models
2006-2008
2009-2012
HOWEVER, THERE ARE ALREADY EXAMPLES / EXPERIMENTS …

WHY IS IT 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 : GeoSciMLNot for 3D (still softwaredependent)
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

MINND - UC8: UNDERGROUND INFRASTRUCTURE
► Scope: standardizing underground infrastructure description process
► One main sponsor Importance of building and environment relationship
► Two main topics and working groups Built environement (tunnels…) description Relationship with its natural environment
► Actions planned Identify exchange requirements (ER) Process description (IDM) Study of digital workflows (services + profiles) Enabling data structure (OGC + BSI standards)

COLLABORATION BETWEEN OGC AND BSI
► Memorandum of understanding• Work on joint standards
Relevant working groups in OGC (similar to bSI rooms)• CityGML, IndoorGML, LandInfra, LandAdministration, Smart Cities• … Geoscience / GeoSciML
► A GROWING PARTICIPATION OF COMMUNITIES / USERS IN THE PROCESS (domain focus)
PROPOSED UNDERGROUND INFRASTRUCTURE PILOTPRESENTED TO NYC MAYOR’S OFFICE, MAY 2016
► 3D integration of underground critical infrastructure with secure online services for multiple applications Routine operations, emergency response with cascading
failures, withstand cyber attacks Foster coordination of local, state, federal governments and
utilities► Suitable to any urban environment, e.g., New York

(UPCOMING) GEOSCIENCE DOMAIN WORKING GROUP
► Initiated by
► Following adoption of GeoSciML, proposal to create a Geoscience Domain Working Group under the umbrella of the Earth Systems Science DWG
► With primary focus on Borehole standards / best practices 3D geological modelling Seismology
► Meeting of DWG in Southampton on 14th September
FINAL REMARKS
► We must address the needs of smart cities and large infrastructures► Deliver data / information / products for shallow subsurface
Derived from our INSPIRE data infrastructure► In partnership with municipalities / engineering and utilities companies / …► PPP Platform business model ?► Through agreed (new) standards
for 3D geology (new OGC group !) “interoperable” with BIM standards (Building Information Modelling)
► Which makes possible the integration of “geology” with city models► Land planners / infrastructure owners and operators must not ignore
anymore the hidden / unknown part of reality that is part of our natural environment
