SUBJECT


Pearson Field Pavement Rehabilitation, PAPI and Sign Replacement - Construction Acceptance
Key Points
  • Pearson Field Airport is owned and maintained  by the City of Vancouver

  • The airport has one major runway.

  • Although there has been periodic pavement surface maintenance efforts since, the runway pavement had not been rehabilitated since 1991.

  • The pavement rehabilitation project was 90% funded through a grant from the Federal Aviation Administration (FAA), and 5% funded through a WSDOTA grant.

Strategic Plan Alignment

 

Goal 1, Objective 1.2: Ensure our infrastructure, including buildings and utilities, is safe, environmentally responsible and well maintained.


Present Situation

The City of Vancouver owns and maintains Pearson Field Airport. The airport serves the local general aviation community with one runway; runway 8-26. The runway is surfaced with asphalt pavement which, although maintained in intervening years, had not be rehabilitated since 1991. With a  design  life expectancy of 20  years,  the existing  pavement  had provided good service, but was ending the end of it's useful life.  Rehabilitation was necessary to continue airport operations

 

The project called for the removal and replacement of the asphalt surface of the 60' x 3250' runway, the replacement of the Precision Approach Path Indicator (PAPI) pilot landing assistance system for runway 26, and the replacement of some field guidance signs.

 

The project was 90% funded from a grant from the Federal Aviation Administration (FAA), 5% funded by a WSDOTA grant, and 5% funded from the Pearson Airfield enterprise fund.

 

The work was completed satisfactorily in accordance with the plans and specifications. Contract costs are summarized below:

 

TOTAL CONTRACT COSTS
Labor, Equipment and Material $749.713.30
Sales Tax $62,975.92
Total $812,689.22
   

 

The original contract amount, including sales tax, was $742,197.46. The final project cost was $812,689.22, which was $70,491.76 (9.5%) more than the original contracted amount. The difference between original contract amount and final contract amount can be attributed to a one change order for work to remediate an area of unsuitable subgrade, a 17% addition to the planned asphalt paving quantities as directed in the field during construction, as well as the typical variances in quantities commonly encountered during construction. 

 

As this project was funded by a federal grant, the City could not require apprenticeship goals.



Advantage(s)
  1. Provided for a new runway pavement surface with a 20-year lifespan.
  2. Replaced an aging pilot landing assistance system with new equipment for runway 26.
  3. Completes the City’s contractual and statutory process for accepting the project.
  4. Formal project acceptance allows for closure on third-party bond claims and facilitates completed project close-out.


Disadvantage(s)
None
Budget Impact

None. Budget has been established for this project in the Airport fund with 90% of the project paid for using an FAA grant, and another 5% being paid by a WSDOTA grant, the Pearson Field enterprise fund is obligated to pay for the remaining 5% using cash balance.


Prior Council Review

Action Requested

Accept as complete the improvements as constructed by Granite Construction Company subject to receipt of all project close-out documentation as required by law.
