Inquiry #1: 1. Please confirm that it is approved and allowed by Caltrans to use all straight strands in all girders with combination of Debonding. It has been a standard procedure and approved by Caltrans precast committee and designers to submit RFI (and receive approval) to change the strand profile from harped to straight for multiple jobs in the past. Straight strands will expedite the production schedule, creates a safer operation for the precast yard and ultimately reduces the precast cost. We propose Debonding strands as allowed by Caltrans (up to 33%) of the strands.
2. Please confirm that the 4” tail at the bottom of vertical welded wire reinforcing (WWR-V) shown on page 421 of 486 is not required. It appears that this 4” tail is drawn as a typo.
3. Please confirm that the web thickness for 7’ tall wide flange girders shown on page 423 of 486 is 7” wide.
4. Please confirm that welded wire (WWR) could be used on 7’ tall wide flange girders shown on page 423 of 486. WWR will be similar to what is shown on page 421 of 486 and spacing will match with spacing shown on page 424 of 486.
5. Please confirm that the 7’ tall girder stirrups will be extended straight from top of the girders and will be field bent by the general contractor. (page 423 of 486)

Inquiry #2: In the specs on page 46, 14-11.06C(3)Excavation- it states in part that the excavated and stockpiled DC soil will be sampled and removed by other forces. Why is the awarded contractor not allowed to bid on the transportation and disposal of the stockpiled DC material? Who are the "other forces". I understand that it needs to be sampled by registered geologists, however I don't see why transportation and disposal portion can't be done by the awarded contractor.
Inquiry submitted 08/28/2013

Response #1: The work in question is not part of the transportation project and as a result not part of this Construction Contract. It is remediation work that is a separate responsibility and therefore is being performed under a separate contract.

Inquiry #39: Section 39-1.18A(1) says to treat the HMA aggregate with dry lime, Section 39-1.19A(1) says to treat the HMA aggregate with lime slurry and Section 39-1.20A(1) says to treat the HMA asphalt binder with liquid antistrip. Since lime slurry and dry lime are both HMA aggregate treatments, is a liquid antistrip treatment an acceptable replacement for lime treated aggregates? Or does Caltrans intend for one of the HMA aggregate treatments to be chosen to be done in conjunction with the liquid antistrip treatment of the asphalt binder? If so, how is one to determine the HMA aggregate treatment method required?

Response #2: If the Contractor exercises its “WMA option” and/or its “greater than 15% RAP” option, the Contractor has the option to choose which aggregate treatments (with lime slurry marination, dry lime with damp aggregate, and/or liquid antistrip) are necessary to meet mix design requirements for California Test 371 or AASHTO T 324 (Modified). The Contractor may need one or more treatments to meet these additional requirements.
