Construction of KC-46A depot maintenance hangars underway at Tinker

After celebrating more than 60 years of KC-135 depot maintenance at Tinker Air Force Base the time has come to transition to the newest of the Air Force’s aerial refuelers.

In July 2016, the United States Air Force, alongside Oklahoma and Oklahoma City officials, formally broke ground on the Sustainment Campus for its incoming fleet of KC-46A Pegasus aircraft.

The Air Force ultimately intends to replace its fleet of aging KC-135 Stratotankers in a three-phased effort, beginning with the KC-46A Pegasus.

According to Boeing, the KC-46A aerial refueler boasts 62,000 lbs. of thrust with a wingspan of 156′ 1″, a165′ 10″ fuselage length, and height of 52′ 10″. Boasting 65,000 lbs. maximum cargo capacity the aircraft also has an impressive 212,299 fuel capacity.

Constructed on a Boeing 767 airframe, the Pegasus is taller, longer and has a larger wingspan than the 707-based airframe of the KC-135 Stratotanker. The larger, more sophisticated aircraft requires new hangars and facilities for depot maintenance.

In 2016, the Tulsa District, U.S. Army Corps of Engineers embarked upon a multi-phase construction project to support the maintenance operations for the KC-46A at Tinker.

Construction is expected to run through fiscal year 2029, with final construction providing hangar space for 14 separate KC-46A aircraft.

“It’s a great opportunity to see an entire project build out all at once for a new platform having that complete campus as one progressive project being done phased throughout the fiscal years gives us a unique opportunity to build something from scratch,” said Isabelle Rico, U.S. Army Corps of Engineers, Tulsa District, resident engineer.

“Usually you’re trying to fit stuff in where you can and that has its drawbacks. Building in a consolidated area gives us synergy and gives us the opportunity to plan well and execute well. It’s nice to have a clean slate and it’s a faster, cleaner, more organized process,” added Rico.

As Rico puts it, “The sheer magnitude of the project brings something to the community from the standpoint of the labor it brings. I think anytime you bring a new platform to a community it adds to the surrounding economy.”

Currently construction is underway on one-bay and two-bay hangar facilities as well as a KC-46A systems integration laboratory.

Work on the one-bay maintenance dock began in September 2016, with an estimated completion date of February 2019.

Final cost on the single bay facility will be just under $35 million.

The two bay hangar currently under construction is scheduled to be completed in September 2019.

Total cost on this facility will be nearly $121 million.

The system integration laboratory is expected to have a total cost of more than $12 million and is projected to be completed in March 2019.


Sustainability Assessments drive push toward energy savings

The federal initiatives for energy efficiency continue to be prevalent in our Nation, affecting the infrastructure in which we work and live, and the tools our communities use every day.

These initiatives are in response to Executive Order 13834 which requires the federal government to promote building energy conservation and management, improve agency water use efficiency and reduce greenhouse gas emissions. To support the requirement, agencies develop baseline data for setting and tracking sustainability goals, and provide an annual report of the results to the Council on Environmental Quality (CEQ) and the Office of Management and Budget (OMB).

This has opened the door to more opportunities for the U.S. Army Corps of Engineers to meet many energy challenges facing federal agencies.

Executive Order 13834 requires OMB to prepare scorecards on Federal agency performance on energy efficiency and sustainability. The annual scorecards are based on data, metrics, and scoring criteria that agencies provide regarding their energy management activities, energy and water savings, greenhouse gas emissions, and associated cost reductions. Performance is assigned a green, yellow, or red score for each goal area.

To meet the Sustainable Federal Building (SFB) goal on the scorecard, each agency provides SFB data in accordance with the Federal Real Property Profile (FRPP) requirements documenting whether or not the building has been assessed and whether or not it meets the SFB guiding principles. The guiding principles focus on five areas for both new construction and existing buildings: employ integrated design, assessment, operation and management principles in new or existing buildings, optimize energy performance, protect and conserve water, enhance indoor environmental quality and reduce environmental impact of materials.

The USACE sustainability scorecard currently shows “red” and zero percent complete for the SFB compliance goal, meaning that the agency was not on track to attain compliance with the guiding principles.  USACE implemented a SFB compliance program in October 2014 by adopting UFC 1-200-02, High Performance and Sustainable Building Requirements, as the USACE guidance on obtaining guiding principle compliance.

Leading the charge in this national effort, is the Fort Worth District. The district is conducting sustainable building assessments for selected USACE owned buildings throughout the United States.

Albert Rice, the Fort Worth District’s sustainability project coordinator, said the Corps of Engineers currently has approximately 312 buildings totaling 6.2 million square feet. By fiscal year 2025, the Corps of Engineers is targeting 0.9 million square feet of sustainable federal buildings for compliance.

To date, the District has assessed more than 124 sites at seven districts and divisions, such as the San Francisco Bay Model and the New Orleans District Headquarters – the largest USACE owned building.

“The assessments are the first step in getting all USACE owned buildings over 5,000 square feet assessed. After the assessments, recommendations for obtaining compliance are provided to the project coordinators. Cost savings and energy efficiency go hand in hand and are key goals of the USACE Sustainability Program,” added Rice.

USACE is and will continue its commitment to compliance with applicable environmental and energy statutes, regulations, and Executive Orders.

Volunteers from California Native Plant Society plant native species outside of the U. S. Army Corps of Engineers San Francisco Bay Model visitor center that will require minimum watering. This meets the Federal Energy Management Program guiding principle metric #8, ‘outdoor water use’, which calls for water efficient landscaping limiting potable water use.
