Management System of Engineering Structures NVF Bridge Conference 2015 Mika Stenmark, Finnish Transport Agency

Need for a new system The present Bridge management system has an out-dated technological platform In the year 2010 highways, railways and waterways were combined under one agency => the new system must manage different structures on all traffic networks The current data model is based on bridges Tunnels, piers, canal structures and waterway navigation marks has been adapted in the system partly ‘forcing’ them into bridge structure In autumn 2014 the implementation project finally started with the working title “TREX” The goal = 1. version in spring 2016 6.11.2018

Focus areas in the development Web and mobile use Information security (= contains data important for defense) Opening the data through interfaces and services Flexibility (= need to manage different structures) Expandability Integration with documents, pictures and other file data Integration with related systems (Service Oriented Architecture) GIS (coordinate-data, map-integration) BIM-model integration User-friendliness 6.11.2018

Statistics of the traffic network - roads, railways and waterways 78 000 km highways of which 800 km motorways 5 900 km railway network of which 90 % on single track 78 000 km of highway 5,350 km 4 300km coastal fairways 14,900 4 000 km inland waterways 11/6/2018

Engineering structures, what are they? The Transport Agency defines engineering structures as: structures that are designed and constructed using strength calculations structural damage caused by design or construction errors can cause: danger to humans or damage to the traffic system remarkable repair costs to the structure or its immediate environment 6.11.2018

How can we manage different structures? Data model has to be generic and flexible User interface must be mainly shared for all structures Some structures require their own special data e.g. bridges, bridge type and bearing capacity information 6.11.2018

Hierachical data model of engineering structures Structure 1 (Bridge) Sub-structure Abutment 1 Pier 1 Foundation Column Cap beam Properties - Material - Dimensions - … Pier 2 Abutment 2 Super-structure Surface-structure Railings Environ-ment Structure 2 (Bridge) Main structure Structures Components / Structural parts 6.11.2018

BIM-model integration Design / Construction phase Combined / coordination model Uses native formats of design tools IFC LandXML Dwg … Preparing the model for maintenance phase IFC ”TREX” Normalised / validated to FTA-standards 6.11.2018

Use of the BIM-models in TREX-database TREX interface for the IFC-transfer model TREX data storage Database data ”Conventional” text-based data Basic data of structures Property data etc Geometry data 2D coordinate data (point, line, area) 3D data of strutrural parts as triangular mesh Document management IFC-transfer file as it is 6.11.2018

Benfits of BIM-model integration Easier, partly automated data flow from design and construction data Visualisation of the data in 3D Using 3D-models to pinpoint damages in inspections 6.11.2018
