Plan Sheet / Specification Reference=NOTICE TO CONTRACTORS

Given that the cross sections will not be available before 10/01/02, the bid opening should be postponed. That simply is not enough time to takeoff, and bid a 10 stage project. 

  • As of today there is no intention of postponing bid opening. Although Addendum No. 2 is still pending and delay may be necessary based on the new information to be provided.
  • It is anticipated that Addendum No. 2 will be issued 10/04/02 and the bid opening date will remain 10/17/02.

Will it be O.K. to put our field office trailer in the job right-of-way ?

  • NO. In accordance with Section 5-1.18 AREAS FOR THE CONTRACTOR'S USE there is no area available and none will be given ever during the contract time due to the multiple projects that will be working concurrently in the same area as listed in Section 10-1.13 COOPERATION.

Plan Sheet / Specification Reference=Item 20 : Temporary Railing (Type K)

Are the stage plans correct relative to "staking" of the k-rail? Not all stages require this anchoring. Why is this now being required? This will greatly increase the workers exposure to traffic, because of the increased time to install and remove the railing.

  • A no cost contract change order shall be issued in accordance with Section 4-1.03 of the Standard Specifications to eliminate the staking of the temporary rail. Section 10-1.26 TEMPORARY RAILING paragraph 7 shall be eliminated and paragraph 8 shall be modified to remove "including removing steel stakes and filling holes". The detail specifically shown on sheet 58 of 470 - CONSTRUCTION DETAILS C-3 (sheet 58 of 470) CONCRETE BARRIER (TYPE K) detail and the various staging plans shall not apply.
  • SEE ADDENDUM NO. 4 - staking of the rail for Items 20 and 147 shall be eliminated.

Addenda No. 1, Section 4 revised the completion time from 480 days to 350 days.
Are you going to change Bid Item No. 2 (Time-Related Overhead) to match the 350 day completion time ?

  • Yes, the TRO will be corrected by addenda. 
  • See Addendum No. 2.

Q:09/25/02
R:10/04/02
Plan Sheet / Specification Reference=104 (f) - Shotcrete, sheet 463 of 470

Typically, these walls have a second CIP concrete application that covers the shotcrete and tieback anchorage. 

  • This is usually the case, but the CIP concrete application is not the case for this retaining wall. 
Being that this shotcrete appears to be the final exposed product, what will be the requirements for shotcrete surface finish, construction joint alignment, and tieback anchorage alignment?
  • The requirement for the shotcrete surface finish is found on page 177 of the special provisions:
    • "The surface finish of the shotcrete shall conform to the provisions of Section 51-1.18, "Surface Finishes," of the Standard Specifications."
    Except for the tieback elevations shown on Sheet 462, elevations for construction joint alignment and tieback anchorage alignment can be determined by subtracting the height of the CIP concrete cap and the various heights of construction joint lifts or tieback lifts on Sheet 463 from the top of wall elevations on Sheet 462.

R:10/16/02
Plan Sheet / Specification Reference= Section 10-1.29 

Section 10-1.29 calls out for an ADIEM-350 crash cushion manufactured by Trinity Industries.
California Public Works Code Section 3400 prohibits a public agency from specifying only one source or manufacturer by name. Will Caltrans except as equal product for this crash cushion?

  • Public Contract Code Section 3400 states, in part, "In those cases involving a unique or novel product application required to be used in the public interest, or where only one brand or trade name is known to the specifying agency, it may list only one."

  • Due to obvious safety concerns, the Department has developed formal processes for traffic products, in the interests of the traveling public, as well as those of the Department and private construction and maintenance workers.  The Department has a formal process by which crash cushions and end treatments for barriers and railings are submitted by the manufacturers, reviewed and tested as necessary for performance by the Department, approved for use on State highways, and placed on a list of approved products.  This is an intensive process.  The products must be approved and on the list to be considered in the design of a project.  Each of the approved products has individual physical and functional characteristics that affect its ability to perform the function needed at the particular location within a project.  The Department determines the appropriate product to be required at each location, as part of the project design, based on such factors as traffic volume, traffic speed, accident history, available space, setback distances, maintenance safety, initial and maintenance costs, and other factors unique to the location and to the products. When the Department has specified only one product, it has determined, through the above process, that only one product can meet the Department's needs at a particular location.  Consequently, the Department's action complies with the requirements of Public Contract Code section 3400.

R:10/16/02
Plan Sheet / Specification Reference= Section 10-1.76

Section 10-1.76 once again specs out one brand name for the REACT system. Will an equal be allowed per California Public Work CODE?

  • Public Contract Code Section 3400 states, in part, "In those cases involving a unique or novel product application required to be used in the public interest, or where only one brand or trade name is known to the specifying agency, it may list only one."

  • Due to obvious safety concerns, the Department has developed formal processes for traffic products, in the interests of the traveling public, as well as those of the Department and private construction and maintenance workers.  The Department has a formal process by which crash cushions and end treatments for barriers and railings are submitted by the manufacturers, reviewed and tested as necessary for performance by the Department, approved for use on State highways, and placed on a list of approved products.  This is an intensive process.  The products must be approved and on the list to be considered in the design of a project.  Each of the approved products has individual physical and functional characteristics that affect its ability to perform the function needed at the particular location within a project.  The Department determines the appropriate product to be required at each location, as part of the project design, based on such factors as traffic volume, traffic speed, accident history, available space, setback distances, maintenance safety, initial and maintenance costs, and other factors unique to the location and to the products.

Plan Sheet / Specification Reference= Item# 60:STRUCTURE EXCAVATION (CRIB WALL), Item#62:STRUCTURE BACKFILL (CRIB WALL)

The two crib wall items were not classified as "final pay" as they should be. Can this be corrected prior to bid?

  • No, and the table for the CRIB WALL quantities as shown on QUANTITIES Q-6 (sheet 279 of 470) re-issued in Addendum No. 2 should be disregarded. The quantities on the original sheet and the Engineers Estimate should be used. 
  • SEE ADDENDUM NO. 4 - the original quantities remain the same, quantity sheet Q-6 shall be re-issued to correct the quantities shown in Addendum No. 2.

R:11/04/02
Plan Sheet / Specification Reference=

The earthwork summary breakdown has a row titled "Design Grading". It is the sum of the contour areas at the on and off ramps, as well as outside shoulder to R/W areas. Your cross section index identifies them by "note 2" but you do not breakdown the qty's by location. Without this breakdown over 50% of the embankment cannot be identified. It would also be helpful to breakdown the "G" Line by NB/SB and median. Will you provide this information.

  • SEE ADDENDUM NO. 4 - the quantity sheet Q-1 shall be re-issued with minor adjustments and further breakdown of the earthwork also the bid item ROADWAY EMBANKMENT shall be added.

Plan Sheet / Specification Reference=Section 10-1.43 CONCRETE PAVEMENT (WITH DOWELED TRANSVERSE WEAKENED PLANE JOINTS) 

In Section 10-1.43 paragraph 1 states:

2. Any portion of a test strip fails to conform to the provisions in Section 40-1.10, "Final Finishing," of the Standard Specifications for straight edge and profile requirements without the use of grinding or other corrective method, or
It also goes on to state:
If test strip fails to conform to the specifications, before grinding, test strip shall be removed at the Contractor's expense.  Additional test strips shall be constructed until the Contractor can demonstrate that test strip will conform to the requirements of these specifications.
The pavement is being constructed adjacent to existing lanes where the existing edge may be irregular, can any leniency be given to allow grinding per Section 10-1.10 Final Finishing in lieu of complete removal? 
  • In accordance with Section 4-1.03 of the Standard Specifications, the State will pay for grinding of the existing adjacent lane if necessary. Grinding of the test strip shall be allowed as a corrective measure. All remaining requirements of Section 40-1.10 "Final Finishing" of the Standard Specifications and Section 10-1.43 of the Special Provisions shall be met.
