Contract 10-0L6304

The responses to bidder's inquiries, unless incorporated into a formal addendem to the contract, are not a part of the contract and are provided for the bidder's convenience only. In some instances, the question and answer may represent a summary of the matters discussed rather than a word-for-word recitation. The availability or use of information provided in the responses to bidder's inquiries is not to be construed in any way as a waiver of the provisions of Section 2-1.03 of the Standard Specifications or any other provision of the contract, the plans, Standard Specifications or Special Provisions, nor to excuse the contractor from full compliance with those contract requirements. Bidders are cautioned that subsequent responses or contract addenda may affect or vary a response previously given.

Q1) Are there cross-sections available for contract no. 10-0L6304? If so, where can we order/pickup them from?

A1) Please refer to Addendum No. 1, dated October 27, 2009, which revised Section 5-1.08, "Supplemental Project Information," of the Special Provisions. Copies of cross sections can be purchased from Stockton Blue Reprographics, Phone (209) 464-8724.

Q2) According to the Typical Cross Sections (x-1 thru x-3) there is no mention of any work happening between stations 64+44.85 to 70+72.67. Can you please specify the work required between these stations?

A2) For additional information, refer to the cross sections available as supplemental project information. Please see response to Question 1.

Q3)Specifications address the potential presence of Aerially Deposited Lead in the excavation. Has there been an ADL study for the project? If so, will the State make available the findings? We are concerned about disposal of the excess, since excess excavation is the property of the contractor.

A3) The lead concentration levels and disposal requirements are identified in Section 10-1.22, "Earth Material Containing Lead," of the Special Provisions.

Q4)Reference to previously asked question. Any amount of lead in the excavated material not just hazardous levels will require some sort of special handling since material containing any amount of aerially deposited lead directly changes where the material can be dumped offsite. Can the exact levels be provided by addendum before bid day or will this be addressed by change order after the bid?

A4) Please refer to the response to Question 3.

Q5) Will the State make the Dust Control Plan that is referenced in Section 5-1.10 available electronically?

A dust control plan is not required. Refer also to Section 14-9.02 "Dust Control" of the Amendments to the Standard Specifications (in the Special Provisions).
