Inquiry #23: Addendum No. 1 only partially clarified the quantity discrepancies between the pavement removal, excavation, and new structural pavement quantities. There are still numerous locations that are in conflict and/or need to be further clarified - for example, how can there be roadway excavation associated with Section No.1 which details the 1.15' existing section to be replaced in kind? They Q sheets imply that the existing section to be removed is not all Concrete Pavement and Base.

Inquiry #27: Bid item 0041 calls out for Prime Coat 84 ton. It is not clear where the Prime Coat will be implemented. Addendum #1 did not seem to clarify this issue in the new Q sheets.

The contract 2018 Standard Specifications and the current Contract Special Provisions do not have a provision for Prime Coat.

Can we please see a Special Provision for this bid item that clarifies when and where it is applied and at what rate? Perhaps this should be additional tack coat being applied to cold planned surface?

Inquiry #28: It appears that the Structure Pavement Quantities Q1-Q6 already include the Roadway Summary Quantities from Sheet Q8. So, no need to add them to the bottom line "From the Roadway Summary".

In essence all the Roadway Quantities (Cold Plane, RHMA, GPI and Tack Coat ) from Roadway Summary Table in Q8 are doubled in Structure Pavement Quantities Table.

Please review and adjust as you see fit.
