Project No. 116743 and 1'. ;15 <br />Request for Approval of Change Order No. 1 <br />March 24, 2014 <br />Page 2 of 3 <br />mitigate potential conflicts, the contractor was directed to furnish and install 3 <br />additional static signs, 2 changeable message signs, 2 speed feedback signs and 8 <br />credit signs (project acknowledgement). These items were not part of the original <br />bid. <br />In addition, the project phasing was revised to minimize the impacts to business <br />owners and residents. Field modifications were made to increase safety, including <br />signage, striping and lane delineation. A prior approval was granted on January 6, <br />2014 (PCO# 1- 3,14- 15,29,50 and 52). <br />AGREED PRICE $183,123 <br />Extra Work at Agreed Unit Prices <br />3. While potholing the water main and services on Broadway, existing buried concrete <br />pavement was encountered. The coring results indicated that cement treated base <br />was present beneath the asphalt concrete pavement but once exposed, the <br />material was more difficult to remove and required additional saw cutting or <br />breaking prior to removal. The export of the spoils was hauled to a different plant for <br />further processing and disposal. <br />The proposed pavement structural section was revised to incorporate the existing <br />buried concrete pavement in the center lanes. The buried concrete pavement in the <br />outer lanes has to be removed to allow for construction of the water main and curb <br />and gutter. These modifications will not sacrifice the integrity of the pavement, <br />maintaining a design -life expectancy of at least 20 years. <br />The following contract items were deleted or decreased to allow for the change in <br />scope. <br />Item # <br />Bid Item <br />Unit <br />Quantity <br />Unit Price <br />Amount <br />3 <br />Cold Milling (3") <br />SF <br />- 10,400 <br />$0.54 <br />- $5,616.00 <br />4 <br />Pulverized Material and Cement - <br />Treated Base(CTB) <br />SF <br />- 241,900 <br />$0.89 <br />- $215,291.00 <br />5 <br />Additional 1% Cement Content <br />SF <br />- 241,900 <br />$0.23 <br />- $55,637.00 <br />6 <br />Remove Excess Pulverized Material <br />CY <br />-5,300 <br />$20.52 <br />- $108,756.00 <br />7 <br />Pavement Fabric <br />SY <br />- 17,850 <br />$5.30 <br />- $94,605.00 <br />21 <br />Furnish and Install Survey Monument <br />EA <br />-20 <br />$1,387.93 <br />- $27,758.60 <br />33 <br />Furnish and Install CPS Unit <br />EA <br />-3 <br />$1,115.56 <br />- $3,346.68 <br />Subtotal <br />- $511,010.28 <br />
