Inquiry #7: On sheet DP-26 at Drainage System #54 the pipe is called out 165.7 LF of 48†RCP culvert to be installed. On Sheet DQ-31 Drainage System #54 is called out as a 48†Cured-In-Place Pipeliner. Since there is no existing pipe in this location it appears that Bid Item #108 is incorrect. Should this pipe run actually be included in the Bid item #82 48†APC? Should item #108 be deleted? Please advise which is correct.

Inquiry #10: The CIPP lining specification section 71-3.08B(1) says that at location 87, the minimum wall thickness for the CIPP is 2 inches or the minimum thickness shown in the authorized installation plan, whichever is greater. This will require the CIPP installed in the 30" diameter pipe to be, at a minimum, over 50mm thick, which is too thick for this diameter of CIPP and will not be possible to install. We will be unable to quote the CIPP lining on this project if this minimum thickness requirement is not removed from the specifications or reduced to something more feasible like 0.76 inches.
