5D-BRIDGE - Finnish bridge BIM
• 5D-BRIDGE (5D-SILTA in Finnish) is an umbrella project under which various separate R&D projects are carried out
• Cooperation between different actors in the consortium:bridge owners, designers, contractors, software producers, etc.• Finnish Road Administration• Finnish Rail Administration• Helsinki City• Oulu University• A-Insinöörit Oy• Destia Oyj• Geotrim Oy • Ponvia Oy• Ramboll Finland• SiltaNylund Oy• SITO Oy• Skanska Infra Oy• Tekla Oyj• Terrasolid Oy• WSP Finland Oy

5D-BRIDGE - Finnish bridge BIM
Idea: Entering from traditional 2D bridge design to use of 5D bridge information model through the whole life-cycle of the bridge

5D-BRIDGE - Finnish bridge BIM
Steps until now
Smart Bridge 2001-2004• 3D process development• 3D modelling of concrete bridges• Design models• Laser scanning: control measurements
5D-BRIDGE 2005-2007• Pilot projects• Also bridge renovation projects• Tekla Structures, Solid Works• Modelling of reinforcement• Use of model in on-site measuring• Evaluation
5D-BRIDGE2 2008-2010• More pilot projects• On-site measurements• Modelling of custom components• Guidelines for bridge modelling• National and International cooperation

Smart bridge (Älykäs silta) 2001 - 2004Quality control• comparing design and as built
models vs. quality requirements

5D-Bridge (5D-Silta) 2005 - 2007Bridge renovation project(Kajaanin varikkosilta)• Existing bridge and depot building
to be removed• New bridge to be built connected to
existing bridge• Source information of present
structures by laser scanning• BIM design of concrete bridge• As built bridge geometry vs.
quality requirements

5D-Bridge (5D-Silta) 2005 - 2007
Traditional 2D-design
+ familiar and safe+ easy to learn+ programs are existing+ easy working with simple line
geometry
- information scattered in many documents
- document management hard- drawings consist lines and text=> no intelligence
- same information in many places- contradictions between documents
Product (information) modelling
+ supports life-cycle thinking+ all information saved in one place+ cumulative increase of information+ details (or objects) consisting product information
+ intelligence of objects makes creation of joints easier
+ fast quantity surveying+ making changes fast in certain
cases
- new and strange- needs change in attitudes- needs investing in new programsand training
- in some cases modelling of detailsdifficult and time consuming

5D-Bridge2 (5D-Silta2) 2008 - 2010Case: Eteläkylän Isosilta, Pyhäjoki, Finland• Museum bridge, constructed 1837• Timber truss structure• Weak condition – needs quick repairing• How the BIM technology can help in
renovation?
What we have done?• Laser scanning• Processing of point cloud• 3D Modelling of structures
based on point cloud• CAD import of point cloud or
modelled geometry• Preliminary 3D Modelling of
the bridge for renovation• Creating drawings of the
existing bridge based on BIM• Preliminary structural analysis
based on dimensions of the model (truss profiles, spans etc.)
• Pilot for classify and visualise of damages

5D-Bridge2 (5D-Silta2) 2008 - 2010Custom components -project• modelling of custom
components used in bridges• based mainly on Finnra
standard drawings made for parapets, bearings, expansion joints, drying equipment etc.
• joints of steel structures (Ruukki-types)
• using premodelled components makes modelling faster
• components will be imported from Finnra standard component library

5D-Bridge2 (5D-Silta2) 2008 - 2010Guidelines for bridge modelling• General guidelines
• requirements for source information• requirements for models in different design
stages• requirements of use of standards
• Guidelines for different software users• in cooperations with producers and users

Further development
• Integrating bridge modelling to whole road design process• Relation to bridge management system and bridge register (= needed model storage?)
• Better standardisation to make data transfer easier• Using bridge BIM during maintenance?
• condition inspection reporting• Further piloting in larger projects
