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:

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.
