GES is currently supporting infrastructure improvements at Fillmore Municipal Airport; a small regional facility located approximately 130 miles north of St. George. Working in collaboration with engineering firm J-U-B Engineers, our Las Vegas and St. George teams are joining forces to provide geotechnical evaluation services that will help shape the future of this airport.
The Fillmore Airport site features an asphalt-paved runway, taxiway, and apron along with associated support facilities. The surrounding area is largely undeveloped to the west, with sparse residential and commercial development to the east and north, a setting typical of rural Utah’s municipal airports serving regional connectivity needs.
We conducted a comprehensive geotechnical evaluation at the site, with a focus on understanding existing asphalt pavement conditions, aggregate base, and subsurface soil characteristics. This includes asphalt pavement and aggregate base thickness measurements, along with subgrade sampling and testing to assess the structural foundation supporting the airfield pavements.
In addition to the pavement evaluation, we provided permeability tests to measure the permeability of native on-site soils, important data for drainage design and any future stormwater management considerations. All findings will be compiled and delivered in a detailed geotechnical evaluation report with design and construction related recommendations for the project team.
Our subsurface borings were advanced to evaluate soil conditions across the site. Groundwater was not encountered within the boring depths. Upon completion, borings were backfilled with cuttings to the base of existing asphalt and finished with an asphalt cold patch to restore surface conditions.
Representative soil samples collected from the borings were submitted for geotechnical laboratory testing to determine key physical and engineering parameters, providing the design team with the data needed to make informed decisions about pavement rehabilitation or expansion.
