Project Description:

GEM participated in the design of an expansion to accommodate larger aircraft at the Owensboro-Daviess County Regional Airport. The project included a 1500 feet permanent extension and a 1400 feet temporary extension to the south end of existing Runway 18-36, an approximately 2100 feet extension to the south end of existing Taxiway “C”, an approximately 261 feet by 178 feet extension to the south end of the existing Million Air Apron, a new hanger along the east side of the new apron extension, and a concrete overlay for all of existing Runway 18-36 and Taxiway “C”. Fourth-eight soil borings and eighteen pavement cores were drilled for this project. The soil borings were drilled to depths of 5, 10 and 15 feet below the existing ground surface in compliance with FAA requirements. The pavement borings were extended through the upper asphalt, concrete and aggregate along existing Runway 18-36 and Taxiway “C”. Penetration testing and split-spoon sampling were conducted at selected intervals in each soil test boring to provide an indication of the strength and compressibility of the soil, and samples for laboratory testing. GEM services also included laboratory testing on selected samples, and preparation of an engineering report summarizing our findings and recommendations as related to: field and laboratory testing procedures and results, pertinent on-site observations, subsurface conditions observations, runway, taxiway and apron pavement designs, site preparation and fill construction recommendations, and other identified geotechnical concerns with appropriate remediation methods. The identified concerns included: soft surface soils, perched groundwater, low lying areas, surface drainage, construction accessibility, topsoil, use of on-site soils as fill, agricultural land, low plasticity lean clays, and existing utilities.
