Inquiry #5: On Page 60 of the Special Provisions for Contract # 08-1C38U4, it states that “ For HMA base, Treat aggregates with lime slurry with marination….” and on Plan Sheet X-1 “Typical Cross Sections”, Note 16 states “Treat Aggregates in the HMA Base with Lime Slurry with Marination”.

Based on these requirements, it appears that lime slurry marination of aggregates is required only for Structural Section number 1 as shown on Plan Sheet X-1. Please provide clarification that lime slurry marination of aggregates is not required for any other Structural Section numbers (i.e. 2, 3,4,5,6,7 and 13) that are listed on Plan Sheet X-1.

Inquiry #12: Bid Item 40 Lean Concrete Base 1370 cubic yards is shown on layout drawings as Structural Section 10 which is designated as LCB (RS) and in summary of quantities Route 10 Ramp Quantities as Lean Concrete Base. As these ramps are in the 10 day closure areas, it would require for sack of time to be the same material as Item 41 Lean Concrete Base Rapid Setting. Will this be addressed in a future addendum?

Inquiry #13: With regards to Question #10 and the quantity variations, out takeoffs for Item 61 JPCP ISC is over 28% less than Caltrans Quantities. This seems a bit more than a rounding error as previously stated.
Will Caltrans consider moving the bid date to address some of these issues?

Inquiry #14: Plan sheets L-40 thru L-43 from station +/- 246+10 to 254+00 and 264+00 to 275+20 indicate both structural sections 8 and 12. Shading in these areas indicate JPCP ISC which contradicts that summary of quantities on Q-5. The quantities for JCPC RS are 15% lower than Caltrans quantities based upon take off area versus Caltrans summary of quantities. The JPCP ISC is 28% lower than Caltrans summary of Quantities. Please advise contractors how to bid based upon the erroneous quantities in the summary of quantities versus actual area take offs?
