Inquiry #12: In order to install the concrete barrier transitions, we have to remove part of the existing bridges, according to plan sheets 277 and 278. Should there be a bridge removal bid item?

Response #2:There is no bridge removal for sheets 277 and 278 because we are not touching the bridge. We are removing an old transition barrier which is covered under Bid Item 114 “REMOVE CONCRETE BARRIER" (8 LF). The quantities are paid in LF.

Inquiry #13: Per the answer to Bidder Inquiry #11, since dowel baskets are to be used should the Individual Slab Replacement (RSC) bid item be considered a Jointed Plain Concrete Pavement (RSC) bid item? Per P8 of the 2018 Standard Plans, Individual Slab Replacements do not need dowel baskets.
Inquiry submitted 01/17/2023

Response #1:Submitted for consideration.
Response posted 01/17/2023


Response #2:"Dowel bar retrofit" (that requires dowel bar basket) can be used as an alternative to "drill and bond (dowel bar)".
Individual Slab Replacement (RSC) (bid item #411105) and JPCP(RSC) (# 401055) are not the same.
ISR (RSC) will be used in this project.

Response posted 01/20/2023



Inquiry #14: Per the answer to Bidder Inquiry #10, Dowel Bar Retrofit (Dowel Bar) which is referenced on 2018 Standard Plan P7 is a different work scope than Drill and Bond (Dowel Bar) which is referenced on 2018 Standard Plan P8. Please advise as to which Standard Plan Section is to be followed by the contractor. The only dowel bars that should need to be placed per the Standard Plan P8 would be at the beginning and end of shift of the ISR work.

Also, the Individual Slab Replacement (RSC) item which is referenced on P8 does not show dowel baskets being needed at the contraction joints as referenced in Section B-B of P8. Please advise.

Inquiry #18: Bidder's Inquiry questions #10, #11, #13, and #14 are asking about the number of dowel bars required and whether dowel bar baskets are required due to the long, continuous runs of individual slab replacement (RSC) being constructed on this project. Your answers have been that dowel bar baskets are required and the drill and bond dowel bar quantity is correct. Your answer also instructs us to refer to 2018 Standard Plan P-8, "Individual Slab Replacement with Rapid Strength Concrete". As you can see from that plan, dowel bars are only required at the beginning and end of each slab pour. Also, there are no dowel bar baskets required transversely within each of these pours (just a sawcut contraction joint) and there are no tie bars that tie the lanes together. Someone asked if the bid item should be called JPCP (RSC) since your answers more describe what is shown on 2018 Standard Plan P-1. Can Caltrans clarify exactly what they are asking us to construct? The cost differences are very significant between the doing the project as shown on sheet P-8 or as shown on P-1.

Response #2:Please use standard plan P-8 for the construction of IRS (RSC).
