I did Underground wreckout about 30 years ago and the cable was double stuffed in poly pipe. Ensure you have a blanket dig permit, a good backhoe, and a really good air compressor.
The usual air spades, jack hammers, digging bars and men who will actually work. The SOW needs to have pot hole sizes spelled out, locates care notoriously wrong. Potholes are great for padding billing!!! especially unforseen problems.
pair count must be taken into consideration, direct bury sucks, but restoration can be itemized, specifically where tree roots are concerned.
heavy chains are must have and chinese fingers and a boxes of electric tape.
