The purpose of the projectwas to provide a new cable route from the mains cubicle location to the station building as there was no existing duct route.
 
Scope of the work:
 
The area to be excavated was CAT scanned and the appropriate paperwork filled in and any restrictions noted on the Permit to Dig.
 
The area was then excavated in accordance with the Permit to Dig.
 
150mm layer of sharp sand was laid in the excavated trench and a 4 inch duct was then laid on the sand and covered with 150mm of sharp sand. A draw wire was installed into the new duct prior to back filling.
 
The excavation was then half back filled and cable warning tape laid. Then trench was then fully back filled and as it was rough open ground, any remnant spoil was spread in the surrounding area.
