About this Project
In spring 2019, Amazon began phase one of its $1.5 billion project at Cincinnati/Northern Kentucky International Airport (CVG). The project will include a 2.6 million square foot sort facility with auxiliary buildings and up to 100 total aircraft parking positions with room to expand in the future. Hunt Construction and Kokosing Construction each contracted Wieser Concrete to produce stormwater drainage box culverts for the runoff on the taxi lanes and new sortation building. Produced in our Roxana plant, Wieser delivered 535 loads/pieces of box culvert for the Hunt portion and 995 loads equaling 1,172 pieces for the Kokosing portion.
The culverts were designed by Wieser Concrete and Delta EAS, while the storm drainage was designed by Gresham Smith. Wieser was selected by both Hunt and Kokosing due to the special designs, ability to meet the tight timeline, and scale of the project. The special culvert designs had a range of fill heights varying from 3′ to 48′ of fill. Additionally, HS-25 and aircraft loading requirements had to be met throughout the project. Many of the culverts had 10% silica fume added to the mix design to help mitigate the effects of the de-icing agent on the concrete while in the culvert. Up to 10 box culvert pieces were poured per day from spring 2019 to December 2020. The Amazon Air Hub at CVG is expected to create at least 2,000 jobs and attract over 100 companies to the region to take advantage of the increased shipping capacity. To date, this is our Roxana team’s largest project ever produced.
