Hi-Rinus,



Piping inch dia based on Pipe sch./class , in gerenal we can assume 30- 40 inch Diameter weld per day by one welder, in case of pipeline projects for STD class pipe,



Pipe trench , execavation depands on soil capacity , we can assume 80 -100 mtr Q. for normal soil.



Back filling subject to how many equipment you want to use,

Hi Rinus



Welcome to Planning Planet.



What exactly is "Process Piping"



This is a very complex question and you seem to be excluding the main factors that determine productivity.



Just laying the pipes in the trench is a side issue compared with all the other factors of urban engineering.



I would be more concerned with traffic control - section lengths - underground obstructions etc.



Unless of course you are on a greenfield site.



Best regards



Mike Testro
