BIM and INSPIRE, for a better integration of built infrastructures in their environment : the MINnD project François ROBIDA Christophe CASTAING Strasbourg, > 1 8 septembre 2017
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 lifecycle; 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 date

EU SUPPORT
THE MINND PROJECT 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) http://www.minnd.fr/en/
MINND OBJECTIVES 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 date
WHY ARE WE (BRGM) HERE? UNDERSTANDING geological phenomena and associated risks. DEVELOPING new methodologies and techniques. THE FRENCH GEOLOGICAL SURVEY THE BRGM IS FRANCE S LEADING PUBLIC INSTITUTION WORKING IN EARTH SCIENCE APPLICATIONS FOR THE MANAGEMENT OF SURFACE AND SUBSURFACE RESOURCES AND RISKS. ITS ACTIVITIES ARE GEARED TO SCIENTIFIC RESEARCH, SUPPORT TO PUBLIC POLICY DEVELOPMENT AND INTERNATIONAL COOPERATION. PRODUCING and disseminating data to support the management of soils, subsoils and their resources. DELIVERING the necessary tools for managing soils, subsoils and their resources, preventing risks and pollution and developing climate change policies. Over 1000 staff including more than 700 engineers and researchers
Our infrastructures and cities are not laying on a flying carpet
KEY CHALLENGES FOR SMART / SUSTAINABLE / RESILIENT CITIES AND INFRASTRUCTURES DEPENDENT OF SUBSURFACE 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 2006-2008 But without shared best practices, common standards and real integration in current urban models 2009-2012
HOWEVER, THERE ARE ALREADY EXAMPLES / EXPERIMENTS City of Lyon City of Toulouse Paris Basin
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 Accuracy / uncertainty Usualy well known (design construction) For 2d : GeoSciML Not for 3D (still software dependent) 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)
PERSPECTIVE FOR GEOLOGICAL DATA BIM project DB BIM project DB BIM project DB Geological model DB Services to query geological models Services to feed geological models
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 PILOT PRESENTED 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 Underground Infrastructure Data Model City p y Existing Municipal Data Sets Pipe Long-Distance Heat citygml:track citygml:road citygml:track Secured Online Access Pipe - Gas Pipe - coolingenergy Pipe - WasteWater Pipe - FreshWater Copyright 2016 Open Geospatial Consortium
(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 14 th 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
