Army Contracting Command, Aberdeen Proving Ground awarded Structural Engineering Group Inc., of Hamilton, Virginia, a $200 million firm-fixed-price, multiple-award indefinite-delivery/indefinite-quantity contract for maintenance, repair, and construction services at Tobyhanna Army Depot on June 23, 2026. The ordering period runs through September 29, 2031, under contract number W51AA1-26-D-A037. Forty-four bids were received for the award, which will fund the physical infrastructure that keeps the Department of Defense's largest full-service electronics maintenance facility operating at full capacity for C5ISR sustainment. Work locations and individual funding amounts will be determined with each delivery order issued under the vehicle throughout the performance period.
Background
Tobyhanna Army Depot, located in the Pocono Mountains of northeastern Pennsylvania, holds a singular position in the defense supply chain. It is the DoD's largest full-service electronics maintenance and repair facility, providing Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance — C5ISR — sustainment support to the joint force. The depot processes a high volume of C5ISR equipment, including radars, satellite communication terminals, night-vision systems, tactical radios, and electronic warfare platforms used by soldiers, sailors, airmen, and Marines in every combatant command theater. Tobyhanna has evolved continuously over decades as military electronics have become more complex and more central to warfighting effectiveness across all domains of modern conflict.
The scope of that mission has expanded as the military fields more networked, software-defined systems. Each new platform entering service creates a sustainment tail: components wear out, firmware must be updated, and assemblies must be refurbished after field use. Tobyhanna absorbs that load at industrial scale. The depot operates repair lines and ships reconditioned equipment back to units worldwide. Keeping the enterprise running requires continuous investment in the physical plant — maintenance bays, clean rooms, high-bay assembly areas, environmental control systems, and utility infrastructure built to handle high-value electronics work without unplanned interruption to the depot's repair output.
Structural Engineering Group Inc. is a Virginia-based construction and facilities services firm. Depot maintenance and repair work of this type falls within a category of base operations and facilities support that Army Contracting Command Aberdeen Proving Ground awards on a recurring basis to maintain long-range facility planning with sustained contractor competition. Multiple-award task order contracts allow the government to issue individual delivery orders against a pool of vetted contractors, preserving competition at the order level while avoiding the cost and time of a full re-solicitation every time a facility project arises. The 44-bid field for this award reflects sustained industry demand for access to depot infrastructure work at major Army sustainment installations.
Key Details
The contract covers maintenance, repair, and construction services at Tobyhanna Army Depot across the ordering period running through September 29, 2031. Specific work packages — building repair projects, construction upgrades, or facility modifications — will be defined and funded through individual delivery orders as requirements emerge from depot planning cycles. The firm-fixed-price structure places cost risk on the contractor, incentivizing accurate scheduling and materials management on every task order. The multiple-award structure means Structural Engineering Group competes against other awardees for individual task orders throughout the ordering period, rather than holding exclusivity over the full ceiling value of the vehicle.
Contract number W51AA1-26-D-A037 carries a ceiling of $200 million. The contracting activity is Army Contracting Command, Aberdeen Proving Ground, Tobyhanna, Pennsylvania — the administrative office co-located with the depot itself. Forty-four offers were received, reflecting sustained industry focus on Army depot infrastructure work and the competitive dynamics typical of large maintenance and construction vehicles at major military installations.
Tobyhanna's C5ISR repair mission directly affects readiness rates across the services. When a tactical communications terminal, radar receiver, or night-vision assembly fails in the field, it enters a maintenance pipeline that frequently routes through Tobyhanna. The speed at which the depot turns around those repairs depends on the physical condition of its facilities. Maintenance bays taken offline for structural repairs, HVAC failures, or outdated electrical infrastructure reduce repair throughput and extend the time a unit operates with degraded or unavailable equipment. The maintenance, repair, and construction IDIQ addresses that vulnerability by keeping a standing contract vehicle available to execute facility projects as needs arise, eliminating procurement lead time that would otherwise delay routine upkeep and the resolution of deferred maintenance backlogs that accumulate across any large industrial campus over a multi-year period.
What It Means for Contractors
The Tobyhanna award reinforces the depot's role as the Army's primary electronics maintenance hub, and signals continued investment in structural and facilities engineering support as the installation modernizes its repair lines for next-generation communications and radar systems.
- Structural Engineering Group holds a position on a $200 million multiple-award vehicle at one of the Army's highest-priority sustainment installations. Actual revenue flows through individual delivery orders; the base contract award carries no guaranteed minimum obligation to any awardee.
- Firms interested in similar multiple-award task order contracts at Army depots should monitor Army Contracting Command Aberdeen Proving Ground solicitations on SAM.gov. These vehicles typically re-compete on multi-year cycles with advance notice periods that allow time to develop past performance packages and identify teaming partners before the competitive window closes.
- C5ISR sustainment is a documented DoD investment priority under the National Defense Industrial Strategy. Contractors with proven facility management experience at active military depots and arsenals are positioned for sustained demand as the military accelerates platform modernization and the volume of networked fielded equipment grows across the joint force.
- Task orders under this vehicle will be funded through Army appropriations as individual projects are scoped and approved. Contractors can anticipate likely work types by tracking Army Materiel Command industrial base assessments and Tobyhanna's congressional budget justification submissions, which detail planned facility investments by project category and fiscal year.
- Firms without a prime position on this vehicle can access depot work through subcontracting. Construction and repair projects at Tobyhanna frequently require specialty trades — electrical, mechanical, structural steel, and environmental controls — that prime awardees subcontract to qualified firms registered in the System for Award Management.
