Keith,
I have a few questions:
1 ) What type of pipe are we to use, SDR-35 or SDR-267
2) What type of embedment are we to use?
3) What is the proper procedure to abandon the existing manholes?
4) Are you going to require any slope protection on the creek bank at
the aerial crossing? We will probably build a bypass to cross the creek
in order to drill the piers.
5) The quantity of 18" is 1759', if you go by station # to station #
there is only 1729'. It is only 30' but it is at a depth of 19' to 20'
which could be a fair amount of money.
Are you going to change the quantity?
6) The quantity for piers is 60 VF, also we must penetrate 5' into rock,
if we drill more than 60' will this be an over run of the item?
I don't have any other questions at this time, but if I do I'll let you
know.
Thank you,
Dewey Bailey
