2) Approve change order authority in the amount of $ 14,914.80 (10%) of the contract amount to cover potential costs associated with unanticipated items of work; and
3) Authorize the City Manager to execute the necessary documents.

Has There Been Previous Council Decision on This:

Yes. Council accepted a grant from ADOT Aeronautics on December 17, 2013 in the amount of $279,000.00 to fund the project. Council approved the design contract for this project at the regularly scheduled meeting of April 17, 2012.

Options and Alternatives:

1) Approve the construction contract as presented. This would allow for timely completion of the project;
2) Reject approval of the contract and direct staff to re-advertise for bid. This would effectively delay the project by several months.

Background/History:

City Council approved award of the design services agreement for this project on April 17, 2012. That design work is now complete. The project was first advertised for bid on July 18, 2012. When bids were opened on August 2, 2012, it was determined that funding would only provide for the first phase of the work. That work was completed in the Fall of 2012. This project, the second phase, was first advertised for bid on January 31, 2014. Bids were opened on February 13, 2014. A total of three firms submitted bids for the project. A tabulation of the 3 (three) bids received is attached and is summarized below:

Bidder			Total Amount Bid
Consultant's Estimate			$ 205,175.00
Robert E. Porter Construction			$ 149,148.00
CSW Contractors			$ 221,628.45
BEC Southwest			$ 299,642.66

Key Considerations:

Replacement of the concrete ramp joints is a routine maintenance function which seals the joints from water penetration and eliminates the potential for degradation of the subsurface soils and consequent damage to the concrete pavement.

Expanded Financial Considerations:

This project is budgeted in FY 2014 in the amount of $240,000.00 in Account 221-07-222-3139. The project is funded by a grant from ADOT Multimodal Planning Division - Aeronautics Group in the amount of $279,000 (90% of the total project cost) with a City match of $31,000. The contract provides for a change order authority of 10% of the amount bid to cover the cost of unanticipated or additional work which may be required during construction. All work is anticipated to be complete in FY 2013/2014.

Community Benefits and Considerations:

The purpose of the project is to use the available grant funds in the most efficient manner to lengthen the service life of the concrete pavements and to avoid costly pavement reconstruction in the future.

Community Involvement:

The Public Participation Goals of Inform and Involve were used In public meetings where the City Airport Commission reviews the Airport Capital Improvement Plan and is updated monthly on project progress and impacts.
