The Importance of Robust Data when Dealing with Natural Events

  1. 1. Submitted to RIMS ForumMarch 2012
  2. 2. • Transport Network Reconstruction Program – Fitzroy Region Queensland Australia – Following the 2009 and 2010 Flooding• Christchurch Earthquake damage 2010/2011• Nelson/Golden Bay Flood Damage December 2011• Fiji Flooding February 2012
  3. 3. – Creation and use of emergency plans– Use of data to allow desktop assessments– Data is used in multiple ways by multiple users– Decisions have to be made often quickly including linking to funding and costs– Contracts are created and awarded– Asset management planning– And many others!
  4. 4. • Out of date information• Data gaps particularly for – What is over, around and under roading networks - it’s either not known or unavailable – Existing resource consents• Data inaccuracies (where it is held!) particularly for – Service locations – Old survey data – Catchment areas• Reliance on local resources for knowledge – is it held in heads or more readily accessible?• Data stored in multiple systems that aren’t easily compatible.
  5. 5. • No prevention strategies in place• Poor solutions and/or decisions are made because of inaccurate or incomplete data• Added costs and delays result from decisions having to be changed• Costs increase due to the need to urgently capture accurate data to allow informed decisions and recovery to proceed• Public/Government’s expectations for a timely recovery cannot be met due to an inability to move quickly without the data• Approach to re-construction may change resulting in delays, costs and compensation• Solutions end up being short-term only• Without resource consent understanding, dump sites for material are unknown
  6. 6. • Accurate and appropriate emergency management plans can be created• Multiple use of data by multiple users• Appropriate decisions can be made by understanding the possible impacts, risks and issues• Planning becomes more robust• Budget setting is more accurate• Recovery is more timely• Longer term solutions are adopted• Re-work is minimised• Contractors are not delayed• Forward planning becomes more accurate
  7. 7. • Consider the accessibility, availability and format of the data• Be careful about Client solution requests that are not feasible• Don’t rely on stored data being accurate• Check asset lists are comprehensive• Comprehensive Lidar Survey and aerial photography information helped with immediate responses• Emergency management plans based on accurate data ensured roads were closed prior to issues occurring• Predicting potential upcoming natural events allows prevention strategies to be put in place
