Q1) Will the approved Keystone Keysystem I retaining wall system a Caltrans approved alternative retaining wall be allowed on this project? If it is can you issue an addendum?
A1) No. This is about changing the crib wall. The Caltrans Standard Type B Crib Wall (page C7A Std plans)cannot be changed at this time.
Q2) Section 4 of ASTM D 5813 defines Type II CIPP to be for partially deteriorated pipe and Type III CIPP to be for fully deteriorated pipe. Appendix X1.1.1 of ASTM F 1216 is targeted solely to a definition for partially deteriorated pipe. Please clarify the conflicting requirement in the special provisions section 1.8.1 on page 82 to classify the CIPP as Type III (partially deteriorated). Is the CIPP supposed to be Type II (partially deteriorated) or Type III (fully deteriorated)? If it is to be Type III (fully deteriorated), then the ASTM F 1216 reference in special provision paragraph 1.8.1 should also be corrected to Appendix X1.1.2. If it is to be Type II (partially deteriorated), then the ASTM F 1216 reference in special provision paragraph 1.8.2 should also be corrected to Appendix X1.2.1. Please advise.
A2) Please refer to Addendum No. 2 dated February 11, 2010.
