8 Crusell Bridge New Landmark Bridge in the Helsinki City Center Completed 2010 Spans 92+52,5m, width 24,8m Pylon top +49,0 Product modeling applied comprehensively from design to construction NVF Annual Bridge Conference 2014

9 Geometry of all structural, and almost all non structural components, in the construction coordinate system Steel structures Steel structures plates and profiles Parts joined by welds or by bolting Include material properties Reinforcement Standard bending shapes Include and number, size, placement and material properties

11 Use of model at the site Collision, detected before installation Drilled steel tube piles and laser scanned points Model viewing for work planning Installation order, collisions Geometrical surveys Single points, measurements, laser scanning NVF Annual Bridge Conference 2014

12 New possibilities Plans and structures for the Pylon leg formwork Scheduling tool was used with the temporary structures NVF Annual Bridge Conference 2014

13 Nahkuri Bridge - Designed 2013, under construction NVF Annual Bridge Conference 2014

14 Design according to the Guidlines for the information modelling by Finnish Transport Agency NVF Annual Bridge Conference 2014

15 NVF Annual Bridge Conference 2014

16 NVF Annual Bridge Conference 2014

17 Required design documentation for construction design Product Model Construction drawings Particular specification Bill of Quantities Cost Estimate Bar bending lists Plan for prestressing works NVF Annual Bridge Conference 2014

18 Proof checking Based on the documentation other than the model Where do you need the drawings if you expect the information read from the model? Drawings shall be prepared according the common practise Filing - Drawings of the standard format are required for filing

19 City Rail Loop (Pisararata) The City Rail Loop is a planned urban railway line for commuter trains under the Helsinki city centre. The loop-shaped railway starts in Pasila and runs in a tunnel via Töölö, Helsinki city centre, Hakaniemi and back to Pasila. At present, problems in train traffic easily lead to disturbances affecting the whole country, since the commuter and longdistance traffic are so closely connected. This new railway line will smooth traffic flow not only for the 1.4 million inhabitants in the Helsinki region, but in the whole country.

20 Largest design project based on information / product modelling in Finland. Complex, built, urban and historical environment. Multidiciplinary Integration of all fields of expertise by modelling In City Rail Loop design process the modelling is expected to: improve communication with authorities and decicion makers give support for city planning help finding possibilities and best practicies improve quality and cost controll in design improve productivity in construction
