2 2 The Finnish Inframodel To improve information exchange between infra design applications and from design to construction, using international open standards. National application document for a subset of LandXML schema (~25% of XSD elements) Defined scope for prioritized exchange cases between design tasks and design to construction Specific implementation agreements & guidance documented Extensions as Feature-elements ( PSets ) Supported by 3 major software vendors in Finnish market (Sito/CityCad, Tekla/Civil, Vianova/Novapoint)

3 LandXML v1.2 LandXML v1.0 26/11/ Inframodel history Pre-study: Analysis of situation and needs in infra information exchange (2001) Inframodel: Requirements and proposed LandXML solution ( ) Inframodel 2: Inframodel specification & software implementations ( ) Inframodel 2 piloting: Road & Rail Administrations guidelines (2007) Inframodel 2 update (2010) in InfraTM ( ) TM = Tieto-Malli (= Data Model), InfraTM driven by public client organisations (Finnish Transport Agency & 6 cities) Inframodel version 3 (2013) in InfraFINBIM ( ): Driven by design & construction companies and software vendors, with InfraTM support buildingsmart International (bsi) LandXML MVD (2013) Based on Inframodel 3 specification Inframodel 4 requirements collection in InfraFINBIM, activites planned to continue under buildingsmart Finland (2014-)

4 8 LandXML A specialized XML data file format containing civil engineering and survey measurement data commonly used in the Land Development and Transportation Industries. Specification as XML schema published under LandXML.org Can support (ideally) several business cases in infra design and construction Source: Nathan Crews, Principal Schema Architect, LandXML.org Issues with LandXML: LandXML.org is (was) a community rather than a standardization organization, now inactive LandXML is a framework rather than a data exchange standard (too many open choices to be negotiated between exchanging parties)

5 9 Why LandXML? IFC most directly applicable/extensible for bridges etc. Long term solution for infra, but not yet available LandXML has its shortcomings, but Short term alternatives for infra design&construction are few (if any) Supported by major software vendors Being used in practise => Finnish infra-sector committed to LandXML-based Inframodel (uptake, further development, internationalisation) Work on international level: buildingsmart Model View Definition for LandXML (ongoing) Development stopped at LandXML.org --> buildingsmart and OGC (Open Geospatial Consortium) exploring options for supporting infra-construction and land development information

6 10 Infra-standards general information map Source and reference data Design objects, structures OGC, ISO19100 series standards Civil engineering data LandXML Basic methods and formats (services, GML) Networks Infra structures Catalogue information Metadata INSPIRE Town and city plans Land survey, maps Transport networks Roads and streets Railways Waterways Bridge structures Inframodel Header information, base information Areal structures Water supply and sewerage Soil investigation information National Finnish Infra-format Buildings Spaces Structures HVAC and mechanical design BOM Scheduling Cost buildingsmart / IFC InfraTM / KSn

7 11 Inframodel scope IM2 +> IM3 Project data project, plan, application, units, coordinatesystem, codings Base data Terrain model, subsoil model surfaces (TINs & breaklines, data points) Road, street, railway, water way Geometry lines Construction layers (TINs) Cross sect design parameters Water supply and sewerage Wells, equipments, pipes, culverts Soil reinforcement, areal planning E.g. mass excavation, noise barriers, landscaping surfaces (TINs) Railways stationing (kilometre referencing system) cant switches Equipments railings fences pedestals (lighting column, traffic signs) properties Infra-classification (type codings) FeatureDictionary + Constrained XML-schema & Enumerations-schema

8 12 Examples of Inframodel3 information Project Terrain model: points/lines/triangles Clay surface: points, triangles Cut surface Road construction surfaces Sound barrier, fence, railing Wells, pipes (drainage) Pedestals (lighting, traffic signs)

9 13 Examples of Inframodel3 information Top surface, linemodel Linemodels of constr.surfaces Clay surface Cut surface Combined model Construction layers fence - railing Road layers Terrain and clay surface Drainage - Equipments

13 23 Inframodel planned versions (IM4, IM5) Metadata elements (origin, accuracy, reliability ) Quantities, Schedules, Status information As-built data Bridges (location), Tunnels Piles, Ground stabilisation Cables, wires, etc. Traffic signs & signals, safety devices Requirements collection and scope definition for Inframodel version 4 on-going, specification development in 2014+

14 24 buildingsmart action Model view definitions with implementation guidelines and improved documentation needed to support LandXML use until IFC Infra-extensions are available (IFC 5) Resolution ITM/IUG accept the new project "OpenINFRA: buildingsmart MVD for LandXML v1.2" as proposed by the Nordic chapter and encourages all chapters to participate in development of this model view definition and to support its implementation and use. =>MVD to be completed by end 2013 MVD (Model View Definition)= a well-defined subset of the totality from a specific viewpoint or specific purposes, with documented implementation agreements

15 25 PROJECT DEFINITION Scope of bsi LandXML work CONCEPT DESIGN FINAL DESIGN TENDERING & CONSTRUCTION 1. Contextual information: exchange data set (file author, date...), project, coordinate systems, units 2. Source data (surfaces, breaklines, data points): geometric data and type codings 3. General transport infrastructure design (roads, waterways and railways): alignment and surface model geometry and type codings 4. Road, railway and waterway design: design parameters, cross sections, properties, base quantities 5. Areal planning: landscaping, noise barriers, geo-structures 6. Water supply and sewerage: pipe networks with pipes, structures, connections and equipments OPERATION & MAINTENANCE x x x x x x
