Where provisions of the following supplementary data differ from those on the original documents, this Addendum shall govern and take precedence. Contractors are hereby notified that they shall make any necessary adjustments in their proposals on account of this Addendum.

Below are supplementary instructions that require minor adjustments of the Contract Details. All Bidder Questions have been posted to the Bid On Line. All Bidders must register to this service for their bids to be considered. Where no further clarification to a Bidders Question is provided, the item is to be Bid as shown on the plans or specified in the specifications. 1. On the Bid Schedule Form, Eliminate Item #9, Class 2 Aggregate Base, from Base Bid. This item of Class 2 Aggregate Base shall be bid as Alternative 1 line item and included in the Total Bid including Alternative 1 only. Refer to Detail 1 and Detail 2 on sheet D1.
