The reclaimer is also used for stabilizing subgrade material by mixing existing soil with water from a connected water truck. (Released/Official U.S. Army Photo By: Edward N. Johnson)

Altus Air Force Base is home to the 97th Air Mobility Wing. The 97th AMW plans and executes C-17, KC-135 formal school initial and advanced specialty training programs for up to 3,000 students annually.

In addition, the 97th AMW sustains C-17, KC-135 airland, airdrop and air refueling mobility forces, and provides air traffic control and weather forecasting for flying operations.

In May, 2018, the Tulsa District, U.S. Army Corps of Engineers began replacing the assault landing zone at Altus. Pilots at Altus AFB use this runway to train in assault landing zone procedures.

The overall contract is for demolition and repair of Assault Landing Zone Runway with Portland Cement Concrete. The repair will include replacing the existing Asphaltic Cement Concrete with PCC.

Requirement consists of 41,000 square yards of runway, 20,212 sy of shoulder, and 9,675 sy of overrun area.

During the 152 day construction phase of the Altus Air Force Base Assault Landing Zone, multiple features of work will be accomplished.

Work will include PCC demolition, ACC demolition, excavation, grading, electrical work, underdrain inspection, asphalt drainage layer installation, PCC paving, asphalt paving shoulder/overrun, and airfield markings.

Core samples were taken as part of the evaluation of the initial concrete test section. Three days after completion of the test section, eight core samples at least six inches in diameter by full depth cut from selected points were taken. The cores will be evaluated for surface paste, uniformity of aggregate distribution, segregation, voids, and thickness.

Concrete will be produced for the Altus ALZ project from one of its two Vince Hagan batch plants. The Hagan plants are identical with a capacity of 1.0 — 11.0 cubic yards per cycle.

“The plant is complete with feed bins, conveyors, weigh scales, cement and fly ash storage, admixture storage and control, batch mixer, and a control shack. A portable generator is provided for site power with access to various chillers and water heaters for temperature control if required,” said Aaron Trice, Tulsa District site Quality Assurance Representative.

According to Trice, “A portable asphalt plant has also been erected on-site at Altus AFB to complete the asphalt paving requirements of the contract. The plant is complete with feed bins, asphalt oil storage, lime and mineral filler silos, load out hopper with certified weigh scales, and bag house for particulate control.”

“With the presence of onsite plants, a construction site will benefit from a constant supply of concrete and asphalt. A steady supply of both is key to ensuring the construction site is as productive as possible,” stated Trice.

“Relying on a concrete supplier to deliver concrete to your site can result in delays. With your own onsite plants, you can ensure that your material is mixed to the exact specifications and quantities required.”

The new assault landing zone at Altus AFB is expected to be complete in early 2019 at a total cost just under $12 million.

Air traffic control tower construction project in full swing at Tinker

Construction of a new air traffic control tower takes shape on Tinker Air Force Base, as U.S. Army Corps of Engineers, Tulsa District personnel work with Air Force partners to keep the project on track for completion in 2019.

In preparation for the project, Air Force Civil Engineering Center provided a scope of work to the U.S. Army Corps of Engineers, Tulsa District, to construct a new 130 foot tower which will also include a 500 square foot air traffic control simulator facility. The new facility will be modern, efficient, and appropriately-sized to house system components directly supporting the mission.

Initial civil site layout on the tower began in January 2018, with the overall facility size established at 8,900 square feet upon completion.

Physical completion is expected to be early 2019. Once complete, the 85th Engineering Installation Squadron from Keesler Air Force Base, Mississippi will install all airfield communications, cable antenna, and translators needed to control aircraft approaching, departing, and transiting.

“It’s exciting for the Corps to be able to build this control tower for Tinker Air Force Base. We had a lot of lessons learned on the Vance AFB tower and we were lucky to have some of the same personnel working on this project”, stated Kendrick Adams, U.S. Army Corps of Engineers, Tulsa District, project engineer, “This control tower will be the most modern structure possible and will closely resemble the tower that the Tulsa District recently completed at Vance AFB near Enid, OK.”

The new air traffic control tower will be equipped with a storm shelter which will be located on the 1st floor and may be of interest to many due to the fact Oklahoma sits in the heart of what is known as, “Tornado Alley.” The design meets sustainable requirements and provides for Leadership in Energy and Environmental Design (LEED) “Silver” certification.

Final construction costs after executed modifications will be around $14.5M.

The existing air traffic control tower was designed and built in 1970 and provides less than 50 percent of the required space to support today’s mission. The tower cab, by today’s standards, is too small and cramped to accommodate all of the occupants. The old 100 foot tall tower and simulator building will be demolished after the new tower has been certified for functionality.

Tinker Air Force Base in Oklahoma City employs more than 26,000 military and civilian personnel. The installation is the largest single-site employer in the state of Oklahoma with an annual statewide economic impact of $3.51 billion, creating an estimated 33,000 secondary jobs. The Air Force owns 4,048 acres, leases 810 acres and has 642 acres of easements with 458 total buildings.

The 72nd Air Base Wing at Tinker provides base installation and support services for the headquarters, Air Force Sustainment Center, the Oklahoma City Air Logistics Complex and 45 associate units assigned to six major commands, including the largest flying wing in Air Combat Command.

Tinker is also home to the 507th Air Refueling Wing which currently flies KC-135’s aerial refueling aircraft and the 552nd Air Control Wing which flies the E-3 Airborne Warning and Control Systems (AWACS) aircraft.

Tinker’s largest organization is the Oklahoma City Air Logistics Complex which houses depot maintenance for Air Force, Navy, Air National Guard and Air Force Reserve aircraft.

This depot is the largest most expansive of three depot repair complexes in the Air Force Materiel Command and provides depot maintenance on the C/KC-135, B-1B, B-52 and E-3 aircraft, expanded phase maintenance on the Navy E-6 aircraft, as well as maintenance, repair and overhaul of F100, F101, F108, F110, F118, F119 and TF33 engines for the Air Force, Air Force Reserve, Air National Guard, Navy and foreign military sales.
