On April 17, 2012, City Council approved an Agreement for Consulting Services with Kimley-Horn and Associates to provide design services for the Concrete Ramp Joint Repair project.  That staff report to Council indicated that Kimley-Horn had been selected and was to be retained for a five year period, and that future design elements would be presented for approval to Council, for FAA and ADOT Aeronautics grant awards as a Supplemental Agreement.  The Concrete Ramp Joint Repair Project has already been completed under the original agreement.
 
A Scope of Work and fee estimate for the Westplex Taxilanes Reconstruction project has been formulated, negotiated and agreed upon in accordance with FAA guidelines for Supplemental Agreement No. 1.  A copy of the Scope of Work and fee estimate is attached.
 
The project consists of removal and reconstruction of pavement on taxilanes for all hangars and tie-downs in the Westplex, and other related work.  Design is to begin upon approval of the Supplemental Agreement.  Construction is scheduled to begin in early April 2013 and be complete in November 2013.

The pavement in the taxilane areas to be removed and replaced is the final remaining pavement on the airport which was constructed prior to utilization of performance graded asphalts.  The pavement is oxidized and has large transverse thermal cracks that require repeated patching and frequent maintenance.  Replacement of these pavements will enhance pilot safety and provide significant improvements to tenants renting hangar space.

Construction of these improvements will increase utility and safety of operations at the airport.  New pavements will provide a higher level of service to tenants using these pavements to access their aircraft storage facilities.

Inform - Construction of these improvements is included as part of the current Pulliam Airport Master Plan Improvements as approved by City Council and the FAA and ADOT.  Approval of the Master Plan included numerous public meetings and hearings where public input was actively solicited.  Public hearings were sparsely attended with very little public input received. In addition, the Airport Commission has had involvement in review of the overall project as part of the airport project updates discussed at regularly scheduled monthly meetings with observations provided in their meetings.  Pilots affected by the construction will be notified of closures and allowed the opportunity to relocate elsewhere on the airport during construction.

Approve Supplemental Agreement No. 1.  This will allow the project to proceed in accordance with ADOT grant agreements.
Do not approve Supplemental Agreement No.1.  This will halt progress on the project.
