I have seen conflicting specifications regarding whether shop drawings or laying schedules follow the approved geometry drawings of trunk water mains. Any thoughts on this?
why would you approve them if they didn't? Contractor had better have a good reason for changing your alignment and the engineer had better agree on it. Otherwise, might as well let the contractor design the waterline.
I confess to be at a loss with your answer. The question is, and I apologize if it was not clearly understood, after the geometry, what comes next? the laying schedule or the shop drawings. I've read specs. that indicated that the laying schedule follows the geometry, then shop drawings come next; other specs. indicate otherwise, shop drawings after the geometry then the laying schedule.
