Coffey County Airport Runway 18‐36 Reconstruction

Coffey County Airport, located seven miles north of Burlington, Kansas, initiated a project to replace the pavement and edge lighting system for Runway 18-36. As part of a master on-call contract, Lochner provided construction administration and observation services.

Lochner’s responsibilities included preparing and executing construction observation plans for the Federal Aviation Administration (FAA) as well as submitting regular reports to airport representatives.

Prior to construction, Lochner developed an engineer’s design report, finalized design, and prepared construction plans and specifications. The team also assisted the airport with FAA coordination, project bidding, the completion of a design/as-built airport GIS survey, and contractor selection. As a continuation of services, Lochner provided construction engineering services to adjust the design as necessary and verify the project met design intent.

Using data from pavement analysis and geotechnical investigations, Lochner produced an engineer’s design report to identify and recommend possible runway rehabilitation options, which resulted in the complete replacement of airfield pavement. Lochner’s replacement design used Portland Concrete Cement Pavement (PCCP) capable of supporting 30,000‐pound, dual‐wheel gear aircrafts. In addition, the design allowed for the recycling of the existing concrete pavement to be used as the proposed base course for the new pavement section. The proposed medium‐intensity edge lighting system consisted of LED energy‐efficient fixtures, which is more cost-efficient over the life of the fixture. A construction safety and phasing plan was also included to identify safe procedures for construction operations and communications. Following the acceptance of the report, the Lochner team prepared construction plans and specifications along with a storm water pollution prevention plan (SWPPP). Lochner also assisted the airport with FAA coordination, project bidding, the completion of a design/as‐built airport GIS survey, and contractor selection. Lochner is currently providing construction administration and observation services.
