5D-BRIDGE - Finnish bridge BIM

Timo TirkkonenFinnish Road Administration, Bridge Engineering

NVF-seminarium2009, Framtidens broar och brobyggare31 augusti - 1 september 2009, Göteborg



• 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



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

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 - 20043D Bridge design modelling


Smart bridge (Älykäs silta) 2001 - 2004As built models by laser scanning• substructures• formwork of superstructure• concrete deck slab• final structure

Original point cloudAs built modelled concrete surfaces

Laser scanning


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

Comparing 2D design to product modelling(Master's thesis of A.Kouvalainen)


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

Laser scanned point cloud with RGB color from images taken by scanner

5D-Bridge2 (5D-Silta2) 2008 - 2010

Creating drawings of the bridge based on BIM

Preliminary 3D modelling of the bridge for renovation

3D modelling of structures based on point cloud

WSP Finland Oy


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
