Plan Sheet / Specification Reference=

Question=(1) For the Green Valley Creek Bridge, will a construction joint be allowed below pile cutoff at the bottom of the column cage?

  • This is a Design Sequencing Project. Please refer to Section 1, "Specifications and Plans" of the special provisions, paragraphs 6 and 7.
(2) Design memorandums for CIDH piles require a minimum of 5" X 5" windows for concrete flow. This appears to be in conflict with section 10-1.55 of the special provisions, which calls for 75mm clear space between PVC test pipes and vertical reinforcing. Please clarify which requirement shall supercede. 
  • Design memorandums are not part of the contract documents. The special provisions are the contract requirements.


(3) To avoid steel escalation, if all of the permanent steel casing for the CIDH piles is purchased during the first phase of construction, will it be paid upon delivery to the site? Is there a location to have it stored on site?
 

  • Payment upon delivery of this material is covered under Section 5-1.16 "Payments," of the special provisions for materials furnished but not incorporated in the work. Payment for the material purchased would be made in accordance to section 9-1.06 "Partial Payments" of the Standard Specifications. Staging areas shown on the plans and any other other locations within the project limits may be used if approved by the Resident Engineer. 


(4) Section 10-1.55 "Piling," of the Special Provisions indicates  that "Acceptance tests of the concrete will be made by the Engineer..." and "Tests will included gamma-gamma logging."  Pursuant to section 6-3.01 of the Standard Specifications, "...all tests shall be performed in accordance with the methods used by the Department of Transportation...", however we are unable to locate Caltrans' defined test method for gamma-gamma logging.  Accordingly, please provide the following information:

 Defined procedures for gamma-gamma logging (Cal Test number);
 Defined procedures for interpretation of gamma-gamma logging results;
 Defined procedures for re-test and interpretation of gamma-gamma logging.
 

  • To date Caltrans has not yet completed the writing of a test method.  For information regarding this type of foundation testing you can visit the following website:http://www.dot.ca.gov/hq/esc/geotech/ft/gamma.htm

Please see Plan Sheets 760 and 761.  Note 1 indicates details not shown are found on the “Retaining Wall Details No.2 Sheet.”  The referred to sheet does not give the footing thickness for the retaining walls.  Scaling the dimensions gives 550mm.  Is this correct.  Please clarify. 

  • Sheet 768, Retaining Wall Details No. 2, indicates that for details not shown, see Revised Standard Plan B3-1.  This standard plan provides details for the retaining walls including footing dimensions.

Question=Stage 1A calls for a temporary AC widening for NB 15.  However,
there is no typical section, structural section or quantities for this work.
In addition, the k-rail in this stage does not protect this work area from
NB 15.  How does Caltrans intend to do this work and pay for it? 
 

  • The temporary AC widening will be handled in accordance with section 4-1.03 CHANGES of the Standard Specifications.  The K-rail shown is not meant to protect this construction work area from traffic. It will temporarily act as a positive barrier in lieu of the removed Thrie Beam guard rail.

Plan Sheet / Specification Reference=Materials Information Handout- Lake Hodges Operating Levels.

Question=It is unclear as to what operating level of Lake Hodges will be
maintained from current time thru September 2006.  Is it correct to assume
that elevation 290' MSL will be maintained during this time?
 

  • No.  The operating level of Lake Hodges varies with weather and surface water

  • inflow.  From the current time until approximately January 2006, Lake Hodges
    will be controlled by weather and surface water inflow.  From approximately
    January 2006 through September 2006 the operating level will be maintained
    at approximately elevation 290 or below for the construction of the Water

2) Page 97 of the plans shows k-rail being staked to the top of ac dike. Is staking to take place only when k-rail sits on the ac dike, or for all k-rail?
 
  • Staking should be done for all k-rails of the Stage 1.
3)Is sand backfill of the existing pipe (N) no pay? The drainage quantities indicate on one schedule no pay and another that it will be payed.
 
  • Sand backfill is included in the price for abandon culvert. There is no item and a zero quantity for sand backfill. (N) Not a seperate pay item, for information only is inadverdently overlooked in the chart for sand backfill on page D-91 of DRAINAGE QUANTITIES. 
4) The as-built bridge plans cannot be obtained at the fax # shown on page 195 of the specifications. Where can we obtain these?

Plan Sheet / Specification Reference=Item Number127, 128, plan sheet 450, 492-493 

Question=What is the difference between item 127 TILE TEXTURE PATTERN BULL-NOSE, and item 128 ARCHITECTURAL SURFACE(BARRIER)?  The quantity summary for item 128 on sheet 450 covers walls 403M, 413M, 416M, and 423M.  Based upon the length of barrier on these walls the bid quantity covers approx. 340mm of rail height for the respective lengths of those walls.

According to the quantity summary on sheet 492-493 the quantity for item 127 covers those same four walls.  Based upon the revised bid quantity of 2500 M2,
this covers an average of 860mm of rail height for those walls.

Finally, walls HV11L and HV9L also show barrier rail with tile texture but according to the summaries neither bid item appears to address these two walls.

Which item should cover payment for the tile texture on the barrier rail for the six walls in question?

Please advise.

  • The difference between the contract items 127 and 128 is mainly in the height and radius size. Plerase refer to section 5-1.04 COORDINATION AND INTERPRETATION OF, PLANS STANDARD SPECIFICATIONS, AND SPECIAL PROVISIONS FOR THE REMAINDER.
