Olsson Associates has been providing engineering services for the Alma Municipal Airport since 2006. Projects have included runway design, apron and taxiway paving and lighting, environmental site assessment, and land acquisition assistance.
The Runway 17/35 paving and lighting project was selected as the 2013 Project of the Year by the Nebraska Department of Aeronautics. This $2 million project was completed in August 2013-ahead of schedule, under budget, and with no change orders. Olsson provided design, bidding, and construction observation services. Prior to the runway construction, Olsson’s land acquisition services included conducting a legal survey, providing environmental site assessment, coordinating with appraisers, and performing a topographical survey.
The project's design included a runway pavement of an existing turf strip, connecting taxiway pavement, and providing turnarounds at each runway end. Other design elements included medium intensity runway and taxiway lights (MIRL and MITL), retro-reflective markers on the turnarounds, rotating beacon, lighted wind cone with segmented circle, and electrical vault work. The project's design also called for tree removal and trimming, county road re-grading to provide adequate approach clearance, and building a property fence.
Bids for the runway project were opened in July 2012 and were 21 percent under the estimate, allowing the alternate bid to be funded. To watch a time-lapse video of the project's construction, click here.
Concrete apron and taxiway
In 2007, the concrete apron and taxiway were constructed. This six-inch concrete pavement job included a 5,000-square-yard apron and short connecting taxiway.
Olsson designed a new layout for the aircraft parking and fueling areas, and was able to justify a larger apron than originally anticipated. The future fuel tank location was revised to make it more accessible for the refueling truck, and to allow for an orderly expansion of the terminal area. The connecting taxiway pavement was designed to match the grade of the future runway pavement.
While not specifically required in the contract, Olsson surveyed the existing grass runway in anticipation of the future runway. Olsson commonly looks ahead to long-term improvements to minimize future construction issues.
