The availability or use of information provided in the responses to bidder's inquiries is not to be construed in any way as a waiver of the provisions of Section 2-1.03 of the Standard Specifications or any other provision of the contract, the plans, Standard Specifications or Special Provisions, nor to excuse the contractor from full compliance with those contract requirements.

Q) Can you provide contour grading plans?

A) No.


Q) Can you provide a digital CAD file of the contour grading plans?

A) No.

A) Copies of the permit are now available at Airport Blueprint, 4854 N. Blackstone Ave, Fresno, CA 93726. Phone number is (559) 225-9055.


Q) When you add up the quantities on the profiles and compare them to the quantity pages for the excavation and embankment, some of the locations are off significantly. For example, using the sheets 180 thru 192, and comparing the sum of the in dividual profiles to the quantities indicated on sheet 303 for the DC line (Channel) 10+00 to 102+35.682, there is 507,060+/- m3 compared to 786,921 m3. The project will be short of material for the embankments if the profile quantities are correct. Without the cross sections, I understand they will be available shortly, we have no way to check and see what are the correct numbers. What do you want the contractor to use or is there an error in the plans, that will have to be corrected in an addendum?

A) Please refer to Addendum No. 2, dated December 15, 2005.


Q) Plan sheet Q-2 displays a table containing roadway excavation quantities. The profile sheets also give excavation and embankment quantities; however, some of the quanties shown on the profile sheets are different than the quantities shown in table on sheet Q-2. For instance, the drainage channel excavation quantity shown on sheet Q-2 is 786,921, but the cumulative quantity show in the profile drawings is only 507,029. Please explain.

A) Please refer to Addendum No. 2, dated December 15, 2005.


Q) When CalTrans designed this job did they intend for the earthwork to be balanced? In other words, did the designers intend for the contractor to have to import fill material for the earthwork to balance? Did the designers intend for the contractor to have to waste material, either on the job or off the job, for the earthwork to balance?

A) Yes. This contract is a balanced earthwork project.


Q) Sheet 302 of the plans shows a table of “Roadway Quantities” . The entry for the DC line shows an excavation quantity of 786,921 m3. Sheets 180-192 show the same DC line in profile. These sheets list the excavation for this line sheet by sheet. The sum of these sheet totals is approximately 507,060 m3. Please clarify why the sum of the excavation shown on the profile sheets for the DC line is not the same quantity listed in the summary. Which is the correct excavation quantity?

A) Please refer to Addendum No. 2, dated December 15, 2005.


Q) Are the Earthworth work quantities included to construct the detours contained in the Earthwork Quantity sheet on "Q2"?. Note: There is an item for the detour removal (Item 34), however; no specific quantity for the construction of the detours appears to be called out.

A) Please refer to Addendum No. 2, dated December 15, 2005.


Q) Sheets 306-312 are planting plans. They show areas designated as UVA’s, or “Undisturbed Vegatative Areas”. UVA areas 32, 36, 41, and 46 separate the DC Line (required excavation area) from the C Line (required embankment area). UVA areas 33, 37, 40, 42, 45, 47, separate the C Line from the D Line (another required embankment area). The way the plans are laid out it appears the access routes from the main excavation area to the embankment areas are spaced at 2000 meter intervals between stations 105 and 166. If we assume we can only access the C and D lines from the DC line using the access points shown at 2000 meter intervals we will be forced to add excessive haul costs to our price. Section 5-1.22 of the special provisions addresses the rules governing the UVA’s. They are somewhat murky. They say the exact boundaries of the UVA’s will be determined by the engineer at a future date. They say we can’t cross the UVA’s but say if our operations harm the UVA’s then we will repair or mitigate such damage. What is your intent? Do you intend for us to haul an additional 5,000 to 6,000 lineal feet on every m3 we dig out of the DC line destined for embankment at the C or D lines? Do you intend for us to be able to cross the 25-75 foot wide UVA’s at a closer spacing which would give a more reasonable and competitive price and then repair the damage at the end of the job? We don’t want to add the extra haul cost to our bid. Please explain your intent in spacing these crossings at 2000 meter intervals.

A) The intent is for a crossing every 1000 meters. The Special Provision is written for exact boundaries and crossing locations to be determined in the field by the engineer, as needed. Partnering is highly recommended in this instance. Please Refer to Sheet PP-5, Sta 123+00, Sta 143+00 for an example of crossing locations.


Q) What is the intent of note 2? The roadway is being raised and there isn't a detour around the work during this construction. Do you intend for traffic to flow through the area during embankment operations? Please explain.

A) Bid in accordance with the contract plans and specifications.


Q) Our drainage quantities for box culverts # 1,2, and 3 mult.cell (4) don't check in with quantities on page 196 drainage quantities.

A) Quantities were derived from the Standard Plans (July 2004). Please bid in accordance with the Contract plans and Specifications.


Q) What is a mult cell?

A) "mult. cell" is an abbreviation for "multiple cell" as shown on drainage profile sheet DP-1


Q) RSP & Fabric Quantities are shown drainage system #39 as Minor concrete (minor structure). Is this correct? Other areas show RSP & fabric Quantities are in (light method B)?

A) The inlet and outlet of this culvert require "concreted rock slope protection."


Q) Sheet 162 of 388 Pin Detail. Do these need to be galvanized or painted?

A) Pins do not need to be galvanized or painted.


Q) Sheet 155 calls for 25mm x 25mm x 17ga. galv. steel mesh fabric. Sheet 162 calls for 1/2"sq. hdwr. cloth. SPs 10-1.06 Page 140 Wire Mesh: Calls for 25mm x 50mm hardware cloth of commercial quality. Please clarify opening size and gauge of hardware cloth.

A) In accordance with Section 10-1.06, "Temporary Fence (Type Desert Tortoise)," use 25-mm x 50-mm wire mesh. Hardware cloth shall be commercial quality and shall be approved by the Engineer.


Q) What is the type of post for Tortoise Fence?

A) Bid in accordance with the contract plans and specifications.


Q) Are the hoops for the pier columns flash welded (butt splice) or may they be lapped spliced? There are normally details showing splice options for the hoops.

A) Per sheet number 378 of 388 of the contract plans, the hoops are "'Ultimate' butt spliced continuous." Ultimate splices cannot ever be lap splices. Other splice types are acceptable assuming they meet the specification requirements for ultimate splices (see Standard Specification amendments beginning on page 29 of the Special Provisions). Electric resistance welds (flash), other weld types, and some mechanical splices can meet these specifications.


Q) There is an existing Sign Structure at the new Cal City Overcrossing depicted on these drawings, but there isn't a method of payment given in the specifications for the removal. Please explain.

A) This work will be performed in accordance with Section 4-1.03D, "Extra Work," of the Standard Specifications.


Q) January index is not posted yet. what do you want us to use for the index (Ib) in our asphalt calculation?

A) January Index is 298.2. This information is available at the following website: http://www.dot.ca.gov/hq/esc/oe/asphalt_index/astable.html
