Inquiry #2: This project was advertised on November 13th. The roiginal specs required a mandatory pre-bid meeting for November 27th. On Friday, November 16th the State issued an addendum changing the MANDATORY pre-bid to Monday, November 19th. One day notification, especially during the holiday season, is insufficient notification to allow contractors to re-schedule and attend the MANDATORY pre-bid. Is Cal Trans going to provide another opportunity to attend a MANDATORY pre-bid meeting and allow the entire contracting community to bid on this project?

Inquiry #50: Bid items 56-61 seem to be missing some quantities.

Bid Item 57 lists a total of 260 class 90 Alt "X" piles but that number does not seem to include the piles from the Washrack or the Fuel Island foundations. My takeoff is showing that there should be 298 piles for this bid item, Please clarify the correct Quantity

Bid Item 61 lists a total LF of 35,717 class 90 Alt "X" piles but I'm finding it to be more around 33,000 including the piling left out in Bid Item 57. Please clarify the correct Linear Footage

On page ST1-0 of the project drawings there is a broken down quantity of the indicator and production piling but the following pages ST1-1 through ST1-6 do not show a distinction between the piles. If these piles could be differentiated that would be appreciated.

Please Clarify

Inquiry #58: We are trying to verify quantities of Item 39 - Roadway Excavation (Type H / CL2), and Item 40 - Imported Borrow. We have calculated excavation and removal of soil down to bottom elevation of the Primary Grade Beams across the entire pad, and then per Stage Construction Sheet SC-1, backfill the entire pad with Import Borrow (1.2 Designated Work 2, SC-1). Is this how the quantities and work was calculated?

The next item of work (1.3 Designated Work 3, SC-1)would then be structure excavation (in the import borrow), construction of grade beams, and any structure backfill which would be paid under the LS Building Item. Is this correct?

Inquiry #59: The electrical Specifications and drawings are separated into two distinct Bid Items. Specification 10-3 and drawings 68-72 are covered by bid item 82, Electrical Duct Bank and Conduit Layout. Specification 12-16 and drawings 97-792 are covered by bid item 86, Building Work.

Specification Section 10-3.04 states "Conduit to be installed underground shall be Type 2 unless otherwise specified."

Specification Section 10-3.08 states "Underground conduits shall be Type 2 encased in concrete...All conduits entering and leaving the manholes and pull boxes shall be bonded together with copper bare conductor with ground clamp connected to system ground. All conduit connections shall be threaded."

Cal Trans Standard Specifications Section 86-2.05A states that Type 2 conduit is "Hot-dip galvanized rigid steel conduit...coated with polyvinyl chloride..."

Nevertheless the duct bank conduits shown on sheets 68 & 69 are called out to be PVC conduit per sheet 616 and the schedule on sheet 639.

It would appear that the intent is to provide concrete encased PVC conduits for the duct banks shown on sheets 68 & 69. If this is in fact the case Sections 10-3.04 & 3.08 should be revised to eliminate the conflict that now exists.

It is also noted that the schedule on sheet 71 conflicts with the schedule on sheet 639 in regards to conduit fill. One or the other of these sheets should also be revised to eliminate conflicts.

All of the remaining underground conduits, except those shown on sheets 68 & 69, are covered by Specification section 12-16. Part 3 1.5 states "Rigid non-metallic (PVC) conduit shall be used in underground, exterior locations." In the same section, near the bottom of page 534, it states "warning tape shall be centered over the conduit and shall be placed over the 6 inch layer of sand covering the conduit as specified elsewhere in these special provisions." It is therefore understood that all underground conduits, except those shown on sheets 68 & 69, shall be PVC with sand encasement.

To recap, all underground conduits shall be PVC (with the exception of conduits at the fuel island that are specified elsewhere to be PVC coated rigid steel). PVC conduits shown on sheets 68 & 69 shall be concrete encased, all others shall be sand encased.

Inquiry #74: A number of questions have been submitted regarding the discrepancy in pile "furnish" quantities between contractor's takeoffs to the Caltrans bid quantitities. I have that same question, since my takeoff for bid item 59 comes in about the same 10% short of the bid quantities. I believe this is due to serious confusion regarding the way elevations and datums are used in specifying pile cutoff and tip elevations. Note that on plan sheet 329 the note that "Elevation +11.70 = Datum 0'-0"". One way for me to get to the bid quantities is to use the actual project elevation for pile tips rather than the building datum, to account for the extra 11.7' per pile times the 266 piles in the Maintenance Building, or 3,112 additional feet of pile.
This is very critical, since it means the 12" square piles would be about 122' long instead of the already lengthy 110' long. It seems that both the pile top and the pile bottom should be set by the same datum, but to get to the bid quantities this appears NOT to be the case. Please clarify this immediately!
