Considering the depth of information required from the prime contractor for the DBE Confirmation/Good Faith Effort Documentation it is unrealistic and unnecessary to provide the escrow information 5 business days after the bid opening. In addition it is extremely difficult to assemble all of the subcontractors required escrow information by the first Tuesday after the bid. We respectfully request this escrow information be required 15 business days after bid opening, giving sufficient time for review and approval prior to project award.

Inquiry #14: There are two significant/large projects that bid or are bidding during the same time frame as this project; CDOT 03-0H10U4 @ $230 million bid on 08/16/2018 and a Contra Costa Transportation Authority project @ $80 million bidding on 08/29/2018. Due to these other project bidding, there is hesitation by many significant subcontractor and DBE's to bid this project. Both contracts are large as is this contract and take an extreme amount of resources to put together, in addition to smaller contracts on the bid calendar. Due to the fact that these large contracts are all bidding in such a close proximity subcontractors and DBE's need more time to prepare bids for this project.
We kindly as the state to consider postponement of the bid date.

Inquiry #20: It is our understanding that the median concrete barrier south of Tormey Drain Bridge is to be installed at the end of the job. This is to allow traffic to be routed in the median during phase 2 and 3. In some bridges, there is a conflict between the median barrier rebar connecting to the bridge decks and routing traffic in the median. The bridges at Tormey Drain, North St and Balls Ferry currently have a cast in rebar dowel detail for the barrier rebar connection to the deck, which will conflict with routing traffic in the median. Please advise if it is Caltrans intent to build this barrier in the last phase of the project. If it is, please provide a rebar detail to install the barrier rebar on the bridges in the final phase of construction. Or provide another solution for this conflict.

Inquiry #21: 1. Every vault shown along the fiber pathway is listed as a SV, splice vault. Is a splice required of the 144 and 48 strand at each splice vault or are most just pass-through, as per detail on ED-11?

2. Per ED-11 there only appears to be 2 points of 6 strand breakout from PM5.91 to PM3.51. Is this correct?

3. Also per EQ-1 there is only 1 location where 6 strand SM fiber is accounted for, Sheet E-3. This appears to be incorrect as there is no splice point on sheet E-3. E-4 shows a 6 strand splice point. Should there be 2 locations with new 6 strand fiber on sheet EQ-1. Per ED-11?
