Street Lighting >Street Lighting - Structural Testing
CWC Policy states that visual inspections are performed every three years and structural every 6 years. The main structural test programme is targeted at steel lighting columns.
- Steel columns – require regular structural testing (because of internal and external corrosion risks).
- Concrete columns – rely more on visual inspection (looking for spalling, cracking, exposed reinforcement), but may also need testing if defects are suspected.
- Cast iron / other materials – are inspected based on age and condition.
Of the x steel columns currently installed on Wolverhampton highways land, y have had a visual inspection in the last three years, and z have had a structural test.
Of the y visual tests, yy columns required a follow-up structural test.
Of the z structural tests, zz columns failed the structural test. Of those failures, zzz have been replaced.
ToDo:
- x, y, z etc. figures above need populating.
- Need information on the visual inspection and structural testing frequencies for all types of column material.
- Ideally this would be a linked page that also shows the total count of each column type (last 3 financial years) that would also feed PMF survey.
- In Confirm we have a Structural Condition Outcome field that is colour-categorised. What is the process once a column is identified as "red", since the assets do not appear to have been replaced, or if they have they have not had a follow-up certificate awarded to show they are valid. This should be a link to a process page as part of the replacements summary.
