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

2. 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

3. 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

4. Statistics of the traffic network - roads, railways and waterwayskm
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

5. 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

18. 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

19. 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

20. 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

21. 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

22. 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
