A bid item was, therefore, included in the contract documents for Street Cut/Pothole Repair. This bid item was for the removal of 2,000 sq. ft. of pavement, including sub grade to a depth of 2 feet, and replacement. Approval of the plans and authorization to advertise for bids was delayed due to protests filed by adjoining businesses over the proposed curbed median. Additional deterioration of the pavement occurred during this delay. After construction was commenced, it was determined that 13,250 sq. ft. of pavement now needs to be replaced. This need was found to be due to failure of the pavement, and not the sub- grade. --- Change Order No. One will delete the bid item for Street Cut/Pothole Repair, and add an item for removal of 13,250 sq. ft. of approximately 5 inches of asphalt concrete pavement. Deletion of the bid item for Street Cut/Pothole Repair will result in a credit of $12,000.00, and the inclusion of an item for removal and replacement of paving will cost about $21,200, for a net increase in the contract price of $9,200.00.
