Agenda Item: Approval of Change Order No. 11, City Contract No. 2012-183 A11, with <br />A. Miner Contracting, Inc., for construction of the Runway 21 L-3R Runway Safety Area <br />Improvement Project in the amount of $26,272.52 <br />Additional CLSM was used to expedite the installation of storm drain pipes underneath <br />Runway 12-30 in lieu of installing granular backfill. This option provided the least <br />impact to normal operations because a shorter runway closure period was necessary <br />through the use of CLSM. The increased cost of CLSM in lieu of the granular backfill <br />was $24,421.85. <br />The two items resulted in a total net increase to the contract in the amount of <br />$43,311.42. <br />Change Order #10 was for work required by the City's Public Works Department <br />relating to the abandonment of a waterline which crosses underneath Runway 21 L-3R. <br />The abandonment reduces the need for waterline maintenance access and the resulting <br />disruptions to normal airport operations when maintaining an infield water hydrant for <br />fire protection services on the airport. <br />While this abandonment was part of the original plans,. the Water Department later had <br />water quality concerns regarding this dead-end hydrant line and requested the addition <br />of a backflow preventer to isolate the on -airport fire line from the water main feeding it <br />outside the airport. This request was received after the project bids were received. The <br />change order resulted in a net increase to the contract in the amount of $36,045.75. <br />Change Order #11 is for work to seal coat pavement areas where paint markings were <br />previously obliterated -and re -stripe portions of the runway. The seal coat is required to <br />re -seal those affected pavement areas to prevent the pavement from failing and the <br />asphalt becoming loose and potentially damaging aircraft. <br />The Federal Aviation Administration and the Arizona Department of Transportation <br />reviewed the change order request and provided their approvals to proceed with <br />Change Order 11 as specified. <br />Financial <br />The net increase of Change Order 11 is $26,272.52. The City's share of the change <br />order is $656.81. <br />The net increase of all contract Change Orders (1 through 11) is $215,050.13 <br />($188,777.61 + $26,272.52). This is an overall contract increase of 2.7%. Of the total <br />change order costs to date, the City's additional cost is $5,376.25 (2.5%); ADOT's <br />additional cost is $5,376.25 (2.5%); and FAA's additional cost is $204,297.63 (95%). <br />Attachment - A. Miner Contracting — Change Order #11 <br />Recommended Action: MOVE to approve Change Order No. 11, City Contract No. <br />2012-183 A11, with A. Miner Contracting, Inc., for the 21L-3R Runway Safety Area <br />Improvement Project in the amount of $26,272.52. <br />K <br />
