  If you are constructing a 48″ diameter gas transmission pipeline you need to consider the trench excavation and the high specifications required by the oil and gas companies.

The pipeline must not be lowered on to rocks etc. The newly welded pipes are treat like babies and have to be put to bed on a layer of  sand which is previously screened and all rocks removed. This sand must be at least 150mm deep and in some cases 300mm all around the circumference of the pipe. If the contractor does not own or has not made provision for hiring sand screening plant, then the sand has to be hauled from suppliers many Km away at great cost.
