  • See Addendum No. 2.
Plan Sheet / Specification Reference=Item 43

Erreca's has built a portion of Stage 1 and Stage 5 work north of Navajo Road for Contract 11-010734. This work is not shown in the bid package. From cross-sections provided, it appears that the amount of export material on the project has now increased proportionally. Will the State be issuing an addendum revising the contract?

  • See Addendum No. 2.
Plan Sheet / Specification Reference=Plan sheet 206, EARTHWORK QUANTITIES.

There are quantities listed for "D1..D6".  It would appear that these are quantities for building the detours. Some of the embankments will be removed in a later stage.  If these detour embankment removals are to be measured and paid as roadway excavation, are the quantities available?

  • The quantities are already included in roadway excavation. 
Plan Sheet / Specification Reference=Item 42, Develop water supply. Special Provision Section 10-1.34 states: "Attention is directed to "Beginning of Work, Time of Completion and Liquidated Damages." elsewhere in these special provisions, regarding availability of water.

I can find no mention of the subject of availability of water in the referenced section of the Special Provisions.

  • See "Materials Information" for available source of water.
Plan Sheet / Specification Reference=Item 43 ROADWAY EXCAVATION, 

Special Provision Section 10-1.35, fourth paragraph states: "Stepped slopes, as shown on the plans or designated by the Engineer, shall be excavated to conform with the typical cross section as shown on the plans.

  • See Plan Sheet C-12 CONSTRUCTION DETAILS (53 of 353).
Plan Sheet / Specification Reference=BID ITEM #119, PLAN SHEET Q-2 SUMMARY OF QUANTITIES 

It appears that the bid quantity for Item#119 is substantially overstated.
In the quantity summary, the second line (900 CY) appears to be in error. Also no provision is made for the concrete quantity in the areas of the overhead sign structures on the "A" Line. Please review and inform us of the correct quantity.

  •  See Addendum No. 2.
Plan Sheet / Specification Reference=

Besides the Plan Sheets listed there is information and requirements for the mandatory disposal site included on other revised sheets and within the Special Provisions. 
Plan Sheet / Specification Reference=QUESTION AFFECTS MULTIPLE ITEMS


  • No.
Plan Sheet / Specification Reference=ADDENDUM #2, SPECIAL PROVISIONS, SECTION 10-1.35 EARTHWORK "Excess material shall be placed with the future Route 52/125 interchange..."

Now that the earthwork is to excavated on one Caltrans project and placed in a mandatory embankment on another Caltrans project, will the trucking of this material be subject to prevailing wage requirements?  If so, does the prevailing wage requirement apply to bona fide owner-operator truckers?

  • Yes, the trucking and placement of the material to the mandatory disposal site is covered work therefor subject to prevailing wage requirements. 
  • Yes, prevailing wage requirements apply to owner-operator trucks. See Question 24.
Plan Sheet / Specification Reference=SITE INSPECTION THIS MORNING

There are loose piles of broken concrete, broken asphalt, dirt, and debris randomly scattered within the limits of work covered by this contract in the area north of Navajo Road.  How are we to address the work involved in loading, sorting, hauling, compacting or disposing of this material?  Is this work covered in some pay item?  If so, which one?  Is this considered incidental to the work and we should anticipate performing this work for no pay since it can be observed in a site visit, as we are frequently advised by Caltrans field staff?

  • The site cleanup is included in the ongoing contract and will be completed before the start of this contract.
Should our schedule of values under Water Pollution Control include quantities for the measures for which there is already a pay item (i.e. silt fence, straw bales, gravel bags, etc....) if we think more of these measures will be required than is shown on the plans.  As an example, say the plans call for 100 straw bales from station A to B and our approved plan requires us to install 120 bales from station A to B.  Should we put the cost of the additional 20 bales in the Water Pollution Control item, or will the extra 20 bales be paid at the unit price for straw bales?

If the approved SWPPP has the same control measures as shown on the plans, but the measures end up in a different configuration than shown on the plans--will the measures be paid for by the contract item?  We ask this question because the special provisions states that any items placed at locations other than as shown on the plans will be paid under Water Pollution Control.  Since approval of the SWPPP is the Contractor's ultimate responsibility, we run the risk that none of the measures will be in the exact location as shown on the plans and that we will be paid nothing for all the temporary control measure items.

Would you please clarify your intent in this area of work?

  • No, the schedule of values should not include items where there is a contract pay item for but the additional control measures should be shown on the plan. 
  • Yes, the additional control measures shown in a different configuration that have a pay item will be paid as increase in contract item at the contract unit price with no adjustment.   

Can Caltrans tell us what the total current hourly rate of a standard, dirt hauling, highway type, double dump truck must be, in order to be compliance with the prevailing wage provisions for owner/operators? 

  • For compliance of an owner/ operator the only requirement is to substantiate their status not to verify wage or equipment payments. Owner / operators need not report hourly wages just gross earnings per week. The owner/ operators must be paid the equivalent rate at least equal to the sum of the equipment rental rate for the equipment used and the prevailing wage rate for the classification of operator.
