Inquiry #5: Section 71-308B(1) states that the minimum wall thickness for Drainage System 8 is 2" (~50.8mm). This appears to be an error/typo. Please remove this requirement as an 18" x 50.8mm or 24" x 50.8mm liner is not constructible. Minimum wall thickness for CIPP should be designed per ASTM F1216, Appendix X1.2.1 as mentioned in Section 71-3.08A(3).

Inquiry #6: Bid Item #38 ROADWAY EXCAVATION for 24,100 CY... This item is broken down and reflected on Plan Sheet Q-1. A takeoff has been performed and the access road quantity appears to be about 3,000 CY lower than shown. Additionally, there is no roadway excavation shown on the plans for the "mainline". The only excavation in the mainline is for the various underground piping items and this excavation is incidental to the pipeline(s) and is not considered roadway excavation.

Please clarify where/what the 10,990 CY of "mainline roadway excavation" or delete if in error.

Inquiry #7: For the "#16 TEMPORARY AUTOMATED END OF QUEUE WARNING SYSTEM (TYPE 1) DAY" & "#17 END OF QUEUE MONITORING AND WARNING WITH TRUCK MOUNTED CHANGEABLE MESSAGE SIGN DAY"... I am referencing the standard plan RSP T26 (Sheet 168) of then plan sheets.

I am having a difficult time understanding what is to be included in the bid item/work... The graphic shows one PCMS but there are nine message options that is confusing me as to whether there is only one PCMS or if there are nine PCMS with one PCMS for each message. Please help clarify.
