Gold Award – Sioux County Regional Airport, Sioux Co., IA
Contractor: Cedar Valley Corporation*
Owner: Sioux County Regional Airport
Engineer: DGR Engineering
Creating a new airport out of an Iowa cornfield is a once-in-a-lifetime experience, according to the engineer who headed up the team that designed the Sioux County Regional Airport. Due to a funding quirk by the Federal Aviation Administration, this concrete paving project was built under two different contracts separated by a year.
In addition to the phasing challenges posed by the FAA multi-year funding package, horrible weather conditions during the two years also posed scheduling challenges. Overall, the airport was constructed during five different construction seasons. Cedar Valley Corporation built a 5,500 lineal ft. by 100-ft.-wide runway. The paving also
included four taxiways, a large apron area, and the concrete around two T-hangars. In all, CVC placed 122,532 SY of concrete. In spite of weather conditions, crews placed concrete 47 different days to complete these projects.
The stops and starts in the project, stemming from the funding issue and bad weather, may have affected the schedule, but did not impact CVC’s focus on quality. The contractor was not allowed to use probes to determine concrete strength, so crews used extra sets of beams to determine early strengths.
CVC met or exceeded all quality goals and despite the difficult site conditions, the company posted an exceptional safety record on the project. There were no loss of time injuries or recordable vehicular accidents with almost 47,000 man-hours of exposure.
