Bridge tasks in Finnra 2006 Central administration in Helsinki Personnel ca 25 • Bridge policies • Tecnical requirements for bridges • Technical support to road districts • Inspection of bridge plans • Managing R&D • upkeep and developement of IT-systems • Statistics Road districts (9) around Finland Personnel ca 15 • Managing of inspections • Managing of maintenance works • Managing of construction works • Datainput toBMS Inspections, Maintenance and Construction works by private partners Dansk Brodag 2006

  11. The Finnish Bridge Management • Policy • Maintenance strategy • Yearly Budget and Targets • Inspection of bridges • Inspection types • Bridge Inspectior Qualifications • BMS (Siltarekisteri) • Reference group for modelling Network Level BMS • Project Level BMS • Programming of the works • Road district • BMS Dansk Brodag 2006

  12. Maintenance Strategy • No bridges with limited load on main roads • Number of bridges with limited load is decreasing • Bottleneck bridges on heavy vehicle routes repaired • Rehabilitation of the bridges under low traffic might be postponded Yearly targets and budgets are set from • The Ministry of Transport and Communications Finland • The Finnish Road Administration, Central Administration Yearly targets Dansk Brodag 2006

  13. Number of Bridges in Very Bad Conditionin 1991-2004 Dansk Brodag 2006
