I have seen on submission for Site Drainage from PTG and now I have received a Site Drainage Plan from SPP and both are difference therefore I have one question which one do I look at.
Anyway the one from SPP have not given Invert Elevation of the Manhole, I cannot give any comment on that, but it seem more economical than PTG. SPP have to develop from that and give me the Invert Elevation of each manhole.
One more thing please settle between PTG and SPP who is going to submit the shop drawing not both of them on the same subject.
