CLARIFICATION

Additional Information Regarding Clarification No. 20, Addendum No. 2:
Page ADD2-Clarifications-3, Question No. 20, regarding field bending of #10 bars, please see the following question and answer below: 

Question: We have examined the use of a hydraulic bender to field bend the outmost #10 bar of 2 bundled bars.  Hydraulic benders cannot be used on bundled bars.

a.    Is it acceptable to use "T"-head on all #10 bars, or

b.   "T" heads on outside bars and have the tails of the inside bars turn in? 

Answer:  While it is true that bundled bars typically cannot be bent using a hydraulic bender, these bars are not in "intimate contact" due to the T-heads.  We believe that the top hoops could be lowered, the hooks bent out, and the hoops relocated after the CIDH concrete has been placed and cured. 

a.   No.

      b.   Since the detail applies only to the retrofit lateral restraint at the abutments (no vertical load will be put on the cap), the "T" heads may be on the outside bars and hooked inside bars may be turned in as long as there is sufficient room for one or more tremie tubes, etc. without cutting the hooks. 

Please fill out the Addendum Acknowledgment sheet (page BB-5 of the Bidder's Book) verifying your receipt of this Clarification (1-25-06).
