Four Corners Regional Airport has been an Armstrong client since 2014. Since then, we have completed numerous AIP projects, a few of which are outlined below.
FAA Identifier: FMN
Airport Activation Date: 1947
Elevation: 5506.4 ft.
Physical Address: 1296 Navajo St. | Farmington, NM 87401
The purpose of this project was to acquire 0.57 acres of land to the south of Runway 5/23 to eliminate the existing through-the-fence operation. The proposed property to be acquired was accessed through existing airport property. The parcel was needed to provide Sponsor ownership to avoid future through-the-fence operations.
The $3.6 million Taxiway E, F, and G project consisted of the design and full depth reconstruction of a group of parallel and connector taxiways. Existing pavements were experiencing severe distress due to poor subgrade conditions and excessive aircraft loads. Working in collaboration with the Sponsor and the FAA, Armstrong designed a cost effective pavement section that supported the fleet mix weight. This allowed for aircraft of over 100,000 lbs., such as C-130s and large corporate jets, to utilize the taxiways. Several geometry issues were also addressed to increase operational safety and functionality.
Despite a late summer release of the FAA grant, Armstrong worked with airport management and the contractor to use an accelerated phasing plan for late season construction. This plan resulted in minimal disruptions to airport operations. This project was completed on schedule and under budget.
This project consisted of one schedule containing defined tasks to be performed on the west end of the safety area of Runway 7. Schedule I involved the removal of the existing concrete drainage slab structure, stabilizing the eroded slope, and installing underground drainage structures to minimize future erosion. The drainage structures installed consisted of a concrete inlet that feeds a culvert pipe that carries storm water over the edge of the mesa and discharges it into a natural gully. The storm drain also uses two manholes that serve both as pipe junction points and as energy dissipaters to reduce the amount of energy from the storm water during significant storm events. This helps to reduce the severity of erosion that will be caused by storm water as it is discharged from the storm drain system. The energy dissipation provided by the manholes will also be aided by the rip-rap stilling pool located at the pipe discharge point.
