The two existing airports in Sioux County, Iowa, built 50 years ago, had constraints that limited both usage and aircraft size. Discussions for a new regional airport to address these issues began in 1999, although earthwork did not begin until 201.
DGR Engineering (DGR) led the design and construction phase engineering for the development of the $30 million airport. Tasks included all phases of design and construction engineering activities.
In all, 17 general contractors and major subcontractors were involved in the project, which opened in November of 2018. Not only can the new regional airport receive larger planes, it can also provide hangar space for 40 aircraft, and has a larger aircraft maintenance shop along with increased charter office space.
In addition to several other phases of the extensive project, construction of the runways and taxiways were completed in three phases beginning with a $3.5 million first grading phase in 2016. The construction of the $4 million initial paving project was completed in fall 2017. A final $5 million paving and electrical project was completed in 2018.
DGR also provided design and construction services for support facilities that included a new 15,400 square foot terminal building and hangar. The terminal building serves as fixed base operator (FBO) offices and as the airport arrival/departure facility.
The hangar also supports FBO services for the new airport. DGR also designed and provided construction observation for the new fuel system which includes twin 12,000 gallon tanks for aviation and jet fuel.

New Water Distribution System
The City’s residents enjoy high quality water that comes to them in a new and reliable distribution system.
Site Development, Utility Improvements
A multi-phase plan for infrastructure projects was developed for the City of Alton.
Health, safety and public welfare were all improved by this project.
DGR engineers helped L&O Power Cooperative improve communications on its electric transmission system using existing transmission lines, fiber and underground fiber line.

Treatment Plant & Well Exploration
DGR Engineering worked closely with OCRWS to design a new Water Treatment Plant to target iron and manganese removal from a shallow groundwater source near the site.
Due to concerns with the age and condition of the structures, along with safety clearances to energized equipment and conductors, a project was undertaken to replace the old infrastructure with new underground lines and associated padmount equipment.

DGR Engineering provided design and construction services for support facilities at the new Sioux County Regional Airport. Plans included a new 15,400 square foot hangar and terminal building. The hangar supports fixed base operator (FBO) services for the new airport. The attached terminal building serves as FBO offices and as the airport arrival/departure facility.
DGR also designed and assisted with construction observation for a new fuel system to include twin 12,000 gallon tanks for avgas and jet fuel.
DGR Engineering completed a recent apron expansion and runway rehabilitation project. DGR is currently designing a hangar area taxiway project. DGR previously provided design and construction services for the $3 million development of a new runway and taxiway. DGR has also managed new hangar facilities, drainage projects, pavement rehabilitation, and other related projects for a total cost of improvements at the airport of over $5 million. Current active projects include: new hangar area development, taxiway design, AWOS relocation, and private hangar development.
