1 Making BIM and GIS interoperable using the V-Con layered modelling approach Bart Luiten, Michel Böhms, TNO GEO BIM Smart Infrastructure 20th November, 2014

2 2 Introduction Road Authorities want to increase their use of BIM (for their projects) and GIS (for asset management) Both BIM and GIS are developing rapidly, with large user groups, acceptance in the market, large installed bases, own technologies However, these two world are not always compatible What to do when you need to work with both? In the V-Con project we aim for solving this issue. Maybe you can learn something from it.

3 3 V-Con Project Context V-Con: Virtual Construction for Roads Aim: improving processes at National Road Authorities by Information Management EC sponsored PCP-project PCP = Pre-Commercial Procurement for software development Partners Rijkswaterstaat, Road Authority, Netherlands Trafikverket, Road Authority, Sweden CSTB, Research, France TNO, Research, Netherlands Duration: 1 Oct Oct years preparation (standardisation & specification), 2 years PCP

4 4 V-Con background Need for improving information management in infrastructure sector However, No standards No demand for software No use at road authorities No demand in Road authorities contracts No investments in software No stimulus to standardise V-Con aims at breaking out of his downward spiral!

5 5 June November 12th, 20, V-Con for Roads - Benno Koehorst With V-Con from paper-based information flows Realisation projects Asset Management Network Management 10% BIM/GIS 10% BIM/GIS National Road Authority Road Realisation Road Maintenance Road Traffic (Control) (Control) Management Today the info flows are paperbased functional road requirements virtual & real road delivery functional maintenance requirements maintenance delivery Legend Core Activity Contractor Road Realisation (Execution) Road Maintenance (Execution) Info flow End-user application (Occ.) project info model 10% BIM

6 6 June November 12th, 20, V-Con for Roads - Benno Koehorst to open information sharing. Realisation projects Asset Management Network Management National Road Authority Road Realisation Road Maintenance Road Traffic (Control) (Control) Management 100% Road Information Model (= BIM + GIS + ) Legend Core Activity Contractor Road Realisation (Execution) Road Maintenance (Execution) Info flow End-user application Shared info model

7 7 How to standardise information exchange and sharing? Many relevant standards already exist BIM, GIS, Systems Engineering, national classification systems, company specific libraries, etc. Each with their own definitions, file formats and semantics And their own user communities, standardisation bodies, installed base, history Our conclusion The mother of all standards does not exist The solution lies in a flexible open linked data approach

8 8 The scope of the V-Con Solution Construction Company V-Con Solution Road Authority Project Management (realisation/ maintenance) Asset Management Traffic Management

9 9 The V-Con challenge Construction Company BIM/GIS/CAD/ V-Con Solution Road Authority Asset Management GIS Project Management Systems Engineering

10 10 The V-Con Vision: use semantic web Construction Company V-Con Solution Road Authority Ontology

11 11 V-Con vision: and allow for existing standards Construction Company V-Con Solution Road Authority Open existing BIM/GIS/SE standards

12 12 A hybrid approach in a multi-standard world Construction Company V-Con Solution Road Authority Ontologies + Open existing standards

13 13 To enable semantic interoperability: use a Common Ontology Defines the structure for Common Datasets Which contain objects and properties to be Common Ontology CMO exchanged and shared between different contexts/domains International Consists of a set of layered Ontologies Concept Modelling Ontology (CMO) National E.g. International, National, Organisation Organisation and Project layers Lower layers specialise higher layers Project

14 14 Multiple Contexts and Datasets Multiple datasets for the same real-life objects where each dataset represents a certain Context One Bridge - different perspectives The Common dataset links these Context datasets V-Con use cases include linking complementary datasets converting datasets enrich datasets

15 15 Example with existing standardised worlds: BIM-GIS syntax mapping Context Ontology Context Ontology syntax mapping Context Dataset V-Con Solution Context Dataset BIM application GIS application semantic mapping Common Dataset semantic mapping Common Ontology W3C Linked Data application

16 16 How to make BIM and GIS interoperable in V-Con? Choices made by two Road Authorities in V-Con: Keep on using existing standards, e.g. for GIS (geospatial) and BIM (structures) Apply as much as possible complementary elements For each LOD, choose either BIM or GIS In V-Con we also contributed to IFCRoads / 3D allignment In practice, still overlaps, hence need for data transformations Use open linked data approach to link these worlds Translate to semantic web (e.g. IFC ontology, CityGML ontology) Use linking, conversion and enrichment to connect different worlds Use a layered structure for the common data structure Allow for specialisation on lower levels

17 17 PCP enables us to realise this with software vendors Pre-Commercial Procurement SOFTWARE COMPANIES SME Large Corporate Develop software Demonstrate Later: Bring to market ROAD AUTHORITIES Rijkswaterstaat Trafikverket (CEDR) KNOWLEDGE INSTITUTIONS TNO CSTB (Standardisation bodies) Define business requirements Create demand Fund development in PCP Develop approach Define technical requirements Standardise

18 18 Status and plans for V-Con Sep 14 we launched the call to involve software vendors in the PCP Last week we received 16 bids! Dec 14 we will select 6 vendors for Phase 1: Solution Design May 15 we will select 4 vendors for Phase 2: Prototype Dec 15 we will select 2 vendors for Phase 3: Develop and Test Sep 16 the market has two running and tested V-Con Solutions! Follow our website to keep up-to-date: Visit our end-conference Autumn 2016 Check our specifications and evaluations; they are public

19 19 Consequences of this approach for harmonisation of BIM and GIS Keep up the good work! Ensure that you are able to communicate with semantic web Try to keep the overlap in scope as small as possible Do not try to include the world of the others Make your own work reusable Try to re-use the modelling work of the others Support initiatives: InfraGML (by bsi and OGC) and bsi InfraRoom Strive for using a layered modelling approach Only standardise the bare minimum ( static ) Allow for specialisations on national and company level ( dynamic )
