Inquiry #2: Sheet E-19 (page 172 of 473): Conduit it to be installed across Bridge #53-1527 (BNSF UC).
It appears that conduit will be installed across an active railroad - will a BNSF permit need to be obtained by Caltrans and will railroad insurance be required by the bidder?

Inquiry #4: The bid express bid system for this contract does not have a section to list DBE subcontractors. There is a section to list ALL subcontractors but no where to indicate if they are being used as DBE participation. Just want to verify that I am not missing something. Please confirm. Thank you.

Inquiry #5: A follow up question in regards to Response #2:
It is this contractor's opinion that the Bidding Contractor does not time or have the responsibility to contact Railroad companies about their requirements. In an effort to maintain a "level playing field" between all bidders, would Caltrans consider all costs borne by the contractor for permits, insurances etc from the Railroad Companies be considered a force account change order at the beginning of the project?

E-77
E-95

On most shots, there is very limit shoulder space, and there are existing Soundwalls/Retaining Walls/Concrete Barriers/Guard Rail/Steep Slopes that leave limited space to setup bore rigs. In this contractor's opinion, the "spud pits' will most likely end up in the middle of the slow lane. Furthermore, the conduit from the "spud pit" back to the edge of the shoulder most likely will need to be trenched in. That would then require extensive freeway lane and shoulder restoration.
Question: What is the preferred boring method and restoration method of these conduit runs in tight spaces that may need extensive restoration?
Inquiry submitted 10/28/2019
Response #1:Please Bid Per Contract Plans and Specifications.

Inquiry #9: On the following Sheets
E-11,E-13,E-53,E-77,E-95,E-121,E-127,E-133,E-151,E-152,E-165,E-192,E-193,E-169,E-178,E-179,E-181,E-183 - there are bore shots shown on the plans listed above that provide difficult access for bore rigs. There are existing sound walls, retaining walls, concrete barriers, guard rails, and steep slopes that attribute to this difficulty. In this contractor's opinion, the setup for the boring rig is such that the "spud pit" may have to be the middle of the slow lane (or even the 2nd lane). This leaves restoration/safety issues. Additionally, the balance of the run back (from the spud pit back to the shoulder) will need to be trenched in - which will need extensive restoration of the freeway lanes and shoulder.
Question: What is conduit boring installation and restoration method for those conduit bore shots with difficult access for rigs?

Inquiry #10: On sheets E-12, E-13, E-14, E-15, E-26, E-74, E-93, E-95, E-151,E-152,E-165,E-168,E-178,E-179,E-183,E-186, it appears that conduit needs to go through existing structures (sound walls, retaining walls, concrete barriers) to get conduit from one side of the structure to the other. What is the conduit installation method in these instances? Core drilling? Is there a standard detail to use? Please advise.
