Inquiry #1: The CIPP lining specification section 71-3.08B(1) says that at location 14, 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 54" 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 0.7 inches.

Inquiry #8: Addendum 1 has changed the Risk Level from 2 to 1 and made it a SWPPP project with REAPs and Stormwater Sampling & Analysis Days. Risk Level 1 projects do not require REAPs or Stormwater S&A Days.
Also, the Water Quality Sampling and Analysis Days do not have the typically associated items Water Quality Sampling Report and Water Quality Annual Report. Is that intentional?
