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) For 80 tons of material, why is Standard process specified? Could the material be switched to Method Process instead? On the same 80 tons, Lime treat the aggregates. Can we be given the option to use LAS in leiu of Lime?

A1) Use the standard process as specified in the Special Provision. Method Process is required for Transporting, Spreading, and Compacting (39-1.11 ) for paved thickness less than 0.15'. Lime treated aggregate is necessary because of the aggregate quality in this area. 24Mar10.

Q2) On the OGFC mix, Lime treated aggregate is specified along with the PG 54-33PM. This seems redundant, since there is no TSR requirement for this mix, can the use of lime treated aggregates be waived?

A2) Lime treated aggregrate is necessary beacause of the aggregrate quality in this area. The grade of asphalt binder must be PG58-34PM as specified in Section 10-1.20, "Hot Mix Asphalt Open Graded Friction Course," of the Special Provisions. 24Mar10.

Q3) Even though lime is required on both the conventional and OGFC mixes, has there been any issues on using aggregate sources from District 7?

A3) Bid in accordance with the current contract documents. 26Mar10.
