T98 Visual Asset Inspection – Stockton-on-Tees Council

We were commissioned by Stockton Borough Council to create their Flood Risk Asset Register and develop a Flood Risk Asset Management Website. Once the register had been updated to include all of their flood risk assets, we identified the locations in a desktop study.


Our inspectors travelled to each location and carried out a detailed condition assessment of over 300 culverts highlighted on the register. The assessments were carried out using GISmapp, in accordance with the Environment Agency’s Condition Assessment Manual (T98). The inspections included recording the condition grades of each culvert using the table below.


The data captured included:

  • General structure details
  • The watercourse channel upstream and downstream
  • Key asset dimensions
  • Any damage to the structure with recommendations for repair
  • A wide selection of photographs.

As a part of the project we also created a Public Facing Asset Register allowing the general public to navigate to a location on the GISmapp website and view the condition of culverts, including photographs of the asset. The Public Facing Flood Risk Asset Register meets the basic requirements under Section 21 of the Flood and Water Management Act (2010).


Under the framework agreement with Stockton Borough Council, we were then commissioned to provide the same service to Darlington Borough Council, currently inspecting over 350 culverts from their own Asset Register.
