This change order was proposed by the contractor and accepted by the City. 1) On both Rd 68 and Burden Blvd the contractor proposed re -compacting the existing base rock that had been under the asphalt for use under the new patch. This proposal helped to shorten the amount of time the lanes on the roadway where closed. Once the contractor removed the asphalt the City Inspector for the project looked at the amount of existing rock present and found that there was adequate rock already in place. The contractor then rec-compacted the existing rock prior to placement of the new asphalt. This change resulted in the contractor completing the same prep work, minus placement of new rock. The contractor utilized the same amount of labor and equipment in order to re -compact the existing rock. The Following Table shows the costs associated with Change Order #8. NO. DESCRIPTION UNIT BID UNIT PRICE QUANTITY TOTAL 1 Labor for Bid Item #9 LS $1048.00 1 $1,048.00 2 Labor for Bid Item #10 LS $12,548.00 1 $12,548.00 3 Labor for Bid Item #11 LS $7,624.00 1 $7,624.00 4 Less Quantity Bid Item #9 SY $4.20 -219 -$9,198.00 5 Less Quantity Bid Item #10 SY $7.50 -2,444 -$18,330.00 6 Less Quantity Bid Item #11 SY 1 $4.20 1 -2,158 -$9,063.60 TOTAL CHANGE ORDER #8 1 -$15,371.60 The price for the labor for each of the bid items was found by subtracting out the quantity of rock installed, and converting the remaining rock which was not installed to tons. The tonnage was this multiplied by the per ton price the contractor would have paid for the rock. This cost was this subtracted out of the remaining cost for the bid item to give the LS price for the labor. Please see the attached calculations. • Page 1 dC vs �u 'a I
