Response #2:Prior to commencing any work on the railroad's right of way, the contractor will need to submit a request for a UPRR Right of Entry which includes some sort of administrative fee. This application can be found on the UPRR web site. Contractor will also need to provide proof of insurance. After the railroad processes the Right of Entry, the contractor then needs to make arrangements with UPRR's Manager of Track Maintenance (MTM) to secure a flagger - contractor should allow for some lag time (4-8 weeks). The flagger should bill Caltrans directly for the flagging costs. The flagger needs to reference our service contract #04R387 in his work order (WO) in order to be reimbursed in a timely manner.

Inquiry #31: On Sheet 169 of 186 - Mococo Southbound Off-Ramp Retaining Wall Details of the project's drawings the sheet pile requirement is specified with a minimum section modulus of 26in^3/ft and the available sections to meet this criteria are Arcelor AZ14 and Bethlehem PZ27. First, Bethlehem no longer manufactures steel sheet pile. Second, AZ 14 Sheet Pile is made by Arcelor Mittal, which is located in Luxembourg, in Europe. This project is Federal-Aid Project ACNHPI-680-1(071)E, which means all of the steel sheet pile should be 100% Melted and Manufacutred in the USA. The specification really should read "Nucor Yamato PZ 27" and "Gerdau PZC 18". Both Nucor Yamato and Gerdau manufacture hot-rolled steel sheet pile and are located in the United States. Please address this on the project's next addendum and make the necessary changes to the project's drawings.

Inquiry #32: On page 69 of the project's special provisions, it states "Replace the 1st paragraph of section 49-2.05B with: Steel sheet pile must comply with ASATM A690/A690 M for interlocking marine grade steel sheet piling and be manufactured by the hot rolling method." All of the sheet piles for this project have to be coated with a zinc coating system (Section 59 of the Special Provisions). Coating the sheet piles will provide the sheet pile with sufficient corrosion protection, and therefore removes the need to have the sheet pile manufactured per the ASTM A690 specification. Since the steel sheet piles are going to be coated, the material should be manufactured per ASTM A572, Gr. 50. This will save the California Dept. of Transportation approximately $160/net ton toward the cost of the steel sheet pile. Please ammend page 69 of the project's Special Provisions regarding Section 49-2.05B, and issue this clarification on the project's next addendum.

Cure the sealing compound as recommended by the manufacture before subsequent painting activities.

Is it Caltrans intentions to caulk all contact surfaces of stiffeners, railings, and built up members?

Will Caltrans identify all the areas that exceed 6 mils for bidding purposes. Due to very limited access on the bridge the contractor has no idea of areas that exceed 6 mils.

The final response we received is that temporary fence and gates are exempt from the Buy America requirement.

**Please see below for the reponses we received on both contracts and clarify if the Temporary Fence and Gates are exempt from the Buy America requirement.




Contract #04-235624 Bidder Inquiry #31: The response we received for Bidder Inquiry #20 was "Response #2:1) RSS section 6-2.05C does not exempt temporary work items from "Buy America" requirements."

We received the following response from Contract #04-0A7104 Bidder Inquiry for the same question:

Inquiry #36: Will the Buy America material requirement for steel products apply to the Temporary Fence (Type CL-6) since this is not a permanent structure?

Response #2:No. Buy America applies only to iron and steel products required to be permanently incorporated into a Federal-aid construction project. Temporary use means that the contract specifications provide that the iron and steel products used on the project either must be removed at the end of the project or may be removed at the contractor's convenience.

Temporary use means that the contract specifications provide that the iron and steel products used on the project either must be removed at the end of the project or may be removed at the contractor's convenience. Also, where a contracting agency is able to document that phased construction is imminent and the steel or iron product will be removed in subsequent near term stages, then the iron or steel product may be considered temporary and not subject to Buy America. However, if the iron or steel product is required to remain in place at the end of the contract (per contract documents) and where phased construction is not imminent, then the product is deemed permanent and Buy America applies.

Inquiry #74: On page 69 of the project's original Special Provisions, it states "Replace the 1st paragraph of section 49-2.5B with: Steel sheet pile must comply with ASTM A690/A690 M for interlocking marine grate steel sheet piling and be manufactured by the hot rolling method."

The project requires 5,260 sq ft of steel sheet pile. There are only two (2) manufacturers of hot rolled steel sheet pile in the United States, Gerdau who manufactures the PZC Series of sheet pile and Nucor Yamato who manufactures the PZ Series of steel sheet pile. With the project drawings requiring a section modulus of 26 in^3/ft the sections most likely used for this project would be either the PZC 18 produced by Gerdau or PZ 27 produced by Nucro Yamato.

To supply this project with the sufficient amount of sheet pile is would require apporx. 68 tons of PZC 18 Sheet Pile (24.2 lbs/sq ft x 5,260) or approx. 71 tons of PZ 27 Sheet Pile (27 lbs/sq ft x 5,260).

Sheet Pile manufactured in conformance with ASTM A690 is not commerically available and not commercially rolled and both mill require 300 to 400 tons to be accumulated before they will commit to rolling sheet pile per the A690 grade. Therefore, maintaining the A690 specification for the sheet pile will force sheet pile suppliers to offer sheet pile per A690 with "subject to accumlation" terms which will make it unclear to the bidders and to CalTrans when the material can be delivered to the project's jobsite.

Therefore it is highly recommended that CalTrans change the specification for the steel sheet pile to the commercially rolled and commerically available grade which is sheet pile manufactured in conformance ASTM A572, Gr. 50 and require that the sheet pile be coated/painted if there are concerns about corrosion.

Inquiry #76: Refering to Sheets 118 and 120, there are 10 Bents that show 6 each "B" symbols and 2 each "C" symbols indicating a total of 60 each B's and 20 each C's. However, using the 60 B's and 20 C's increases the total weight of the corbel plates to nearly 350,000 pounds which is significantly over Caltrans estimate. This indicates there might be an issue. Examining the details for C's and B's shows they straddle a corbel on both sides. Does each B and C symbol represent an occurance of the respective details? Or, does each symbol represent a side of the respective detail? This represents a serious discrepiancy in the plans and should be addressed immediately. It is in the interest of the state to clarify how to interpret these references to the B and C details.

Response #2:Please refer to Sheet 128 and 129 of 186 for placement of corbels B and C. Each symbol represents a single girder support that is placed on its respective side of the bent. These girder supports are connected by a straddle plate for types B and C to form a corbel system. There should be 2 symbols for each B or C system as shown on the details in sheets 128 and 129.

Inquiry #82: Addendum 3 delayed the bid date and mentioned a potential upcoming addendum which would presumably have new/revised information. Respectfully, in the interest of time management:
1) Is there a timeframe for the issuing of the upcoming Addendum?
2) Will the Bid date be changed to a 4th bid date?

Inquiry #83: Ref. Plan Sheet 116 of 186, Notes (Construction Sequence for Steel Corbels); Note 1 states “Coring and drilling operations shall be performed before the fabrication of steel corbels. Holes in plates shall match the field conditions of the cored and drilled holes in concrete”. Also refer to the requirements of Special Provision Section 75 which states “Replacement of cable-type restrainers at adjacent bents is not allowed. At a bent, no more than half of the cable restrainers may be removed at a time” We feel that if NONE of the corbel fabrication can begin prior to the drilling of holes in concrete, the project schedule cannot be met. In order to meet the project schedule, corbels must be prefabricated without holes prior to coring and drilling holes in concrete. Holes in the corbels will then be drilled and corbels shop painted after coring and drilling of holes in concrete. Please confirm this is acceptable.

Inquiry #84: Referring to Inquiry # 83, this is a legitimate area of concern for all. There are in excess of 3,000 plate parts many of which will be drilled for more than 3,000 holes (some skewed). . .all to be matched with field drilled holes that many times are intended to correspond with holes on the opposite side of the bent...
Fabricators must plan and price per the contract drawings which imply a certain level of repetition of tasks such as drawing shop drawings, laying out, and drilling the plates. Depending upon the extent of variations in actual final measurements, there could well be increases in cost to produce and install these plates. And, changes in schedule. .. The design documents do as they must and assume conditions based upon information available to the design team to convey the plan. . .which they have.
The accuracy of the holes will likely fall to the party drilling them. Conflicts between accurately drilled holes and items currently embedded within the existing bents will be the owner's responsibility. The biggest challenge here though is going to be getting accurately place holes which are drilled perpendicular with surfaces or planned skews and they must, when required, match holes on the opposite side of the bents. . .I think this falls into "means and methods".
I'm not sure if my interpretation of this situation is correct but it has applied every time I've crossed similar circumstances during my career - variations in the hole locations or plate shapes are "unforeseeable conditions".
Please let me know if my interpretation of this circumstance is incorrect and elaborate on what Caltrans' interpretation of this circumstance is.
Respectfully submitted.
