Crossover

Does anyone know how much approx a crossover costs? Our builders have to replace our footpath because the whole thing was sinking but we have to pay for the crossover. The concretor is saying we have to pay cash. We want a written quote with details. Also they never actually replaced two panels of the crossover. { this was a knockdown - rebuild}.

Recently got a few quotes for our crossover (which included moving it slightly from where it is now) which was between 4,500 - 5,800.
