This presentation will cover:
• Background context of Bridge Strikes
• General concepts of Cost Recovery
• Lessons learned from a typical emergency
recovery
This is not a technical presentation – no time to
make things complicated in an emergency!

• The railway often older than the road
• Many low clearance rail over road bridges
• Average of 34 strikes per year
• Usually at least 1 catastrophic strike a year
• Likely bridge strikes are unreported
Background

The damage can
be catastrophic
but…

The bridge
usually wins!

In New Zealand:
• The driver of the vehicle is liable
• If a hit and run – the local authority is liable
• Insurance companies used to agreeing costs
before expended – Not possible for Bridge
Strikes
General Concepts of Cost Recovery
![Page 8: RAIL OVER ROAD BRIDGE STRIKES - DISCUSSION OF AN EMERGENCY RECOVERY …€¦ · Small Bridges Conference Melbourne, November 2015 DISCUSSION OF AN EMERGENCY RECOVERY IN A METRO AREA](https://reader033.vdocument.in/reader033/viewer/2022053012/5f0f66657e708231d443f8a1/html5/thumbnails/8.jpg)
General Concepts of Cost Recovery
![Page 9: RAIL OVER ROAD BRIDGE STRIKES - DISCUSSION OF AN EMERGENCY RECOVERY …€¦ · Small Bridges Conference Melbourne, November 2015 DISCUSSION OF AN EMERGENCY RECOVERY IN A METRO AREA](https://reader033.vdocument.in/reader033/viewer/2022053012/5f0f66657e708231d443f8a1/html5/thumbnails/9.jpg)
• Engineers lead initial response if catastrophic
• Dedicated cost recovery team manages
interfaces beyond initial response
• Short term aim is to record and recover ALL
costs - Average cost to KiwiRail is NZD$18,000
• Long term aim is to reduce bridge strikes
General Concepts of Cost Recovery
![Page 10: RAIL OVER ROAD BRIDGE STRIKES - DISCUSSION OF AN EMERGENCY RECOVERY …€¦ · Small Bridges Conference Melbourne, November 2015 DISCUSSION OF AN EMERGENCY RECOVERY IN A METRO AREA](https://reader033.vdocument.in/reader033/viewer/2022053012/5f0f66657e708231d443f8a1/html5/thumbnails/10.jpg)
It is not just physical repair costs that can be
recovered:
• Internal staff time and external Consultants
• Disbursements (hotels, flights, meals)
• Revenue losses
• Speed restrictions
• Alternative transport (buses, road bridging)
General Concepts of Cost Recovery
![Page 11: RAIL OVER ROAD BRIDGE STRIKES - DISCUSSION OF AN EMERGENCY RECOVERY …€¦ · Small Bridges Conference Melbourne, November 2015 DISCUSSION OF AN EMERGENCY RECOVERY IN A METRO AREA](https://reader033.vdocument.in/reader033/viewer/2022053012/5f0f66657e708231d443f8a1/html5/thumbnails/11.jpg)
Pitfalls;
• Must be able to prove costs – Good
documentation!
• Never discuss costs unless based on evidence
• Insurers will not pay for betterment
• Large claims likely to be contested and may
take years to recover
General Concepts of Cost Recovery

• Cost recovery is a worthwhile process

Br 30 WL – Bridge Strike on 7th January 2015
Lessons learned:
• Recognize the limits of your knowledge
• Assess and mitigate risks (design, fatigue,
unknowns)
• Reinforced the value of BOL planning
• Don’t compromise – impact beam was hit
within 72hrs of the bridge re-opening
