Inquiry #11: The quantity for bid item 146 (F) is 76 cy. The Avenue 12 OH bridge states that there are 76 cy of slope paving at this location. However, various plan sheets for Ave 12 OC (sheets 412-443) show slope paving at this bridge as well, which would mean there is a bust in the State's quantity.

Will an addendum be issued changing the Engineer's estimate quantity of item 146 if slope paving is to be placed at this location?

Inquiry #12: Bid Items 70 and 71 are listed as Final Pay items. I have never seen these listed as Final Pay on any other project I have bid.

Inquiry #18: The Department of Fish and Game permit states that a water diversion is required when equipment is in the Cottonwood Creek Channel. Recent typical Caltrans projects either show on the plan sheets or describe in detail in the Special Provisions or Permits what is required for said diversion. Neither of these is present here; is the contractor able to design whatever diversion will work for the contractor's operations? If the contractor is to design our own diversion, what are the flows that need to be passed by said diversion? Lastly, most projects state specific periods of the year when any "in-channel" activities are prevented; this information is not present either in the Permits nor in the Special Provisions. Is the contractor able to work year round within the Cottonwood Creek channel as a result?
