1. How many public lighting columns is your authority responsible for?
16,777 Highway and Amenity lighting columns.

2. In a typical year how many lighting columns does your authority test for structural integrity? Information on electrical testing is not required.
We anticipate that we will structurally test circa 450 to 500 columns per annum over the next few years.

3. What methodology does your authority use to test structural integrity ? e.g. Ultrasonic Testing (UT), push-pull method etc. If you use more than one method please state all methods used on a regular basis and state which is the most used method.
Wokingham Borough Council use a “Force Deflection NDT Stability Test” (Push-pull).

4. In a typical year, how many lighting columns does your authority replace? Preferably the response should be replacements due condition or end of serviceable life rather than replacement due to accidental damage, however if condition/service life data only is not available, then total number of replacements typically per annum is sufficient.
We undertook a major capital programme of LED upgrade including replacement or aged columns during 2016 to 2019. We have not had to replace any columns due to age or condition to date since then. This situation will of course change in future years as our current stock ages.
