About this vehicle

The Department of the Army Materiel Command Communications Electronics Command established this Master IDIQ on September 28, 2012, with a shared ceiling of $7 billion; the ordering period closed on September 27, 2022, halting new task order activity three years and nine months ago. The vehicle is no longer active for new orders, though task orders with ultimate completion dates extending into 2024 remain in performance.

Across 66 task orders with a combined potential value of $2.79 billion, the vehicle funded software engineering, systems engineering, and technical services supporting CECOM's Software Engineering Center across multiple directorates and divisions. Work spans post-production software support, staff augmentation, field support, data architecture, business application sustainment, and tactical network software support. Task orders funded worldwide field support and garrison operations, with place of performance including sites across the continental United States and overseas locations for mission command training centers and field deployments.

Mantech Advanced Systems International leads by potential value with $845.9 million across six orders, followed by Caci Technologies ($514.6 million, 12 orders) and Leidos ($431.4 million, seven orders). These three firms capture the largest share of activity by dollar volume; Logistics Systems Incorporated and The Keyw Corporation round out the top five. Nineteen other contractors hold the remaining task orders, creating a moderately concentrated but diverse competitive base.

Ordering was heavily concentrated within CECOM itself, which placed 46 of the 66 task orders valued at $1.93 billion combined potential value—roughly 70 percent of vehicle activity. Remaining orders funded Army Contracting Command Aberdeen Proving Ground, Army Headquarters Office of the Chief of Staff, and acquisition support centers for command control communications and enterprise information systems.

Set-aside distribution reflects an unrestricted vehicle: 61 task orders (92 percent) carried no set-aside, four small business orders (6 percent) competed among eligible SBs, and one veteran-owned small business order (2 percent) was sole-source. Cost-Plus-Fixed-Fee dominated pricing across nearly all orders; typical task order ceilings ranged from roughly $5 million to $350 million, with the largest being W15P7T12DE005-KX01 at $351.5 million ceiling for worldwide field support. Obligated dollars total $1.7 billion, representing 61 percent of combined potential value. Ordering momentum slowed sharply after 2016, with no new task orders placed after March 2021.

Description

The primary objective of this Master IDIQ is to acquire scientific, systems engineering, and software engineering technical services to support the life cycle activities associated with CECOM Command's Software Engineering Center (SEC) WMA, BMA, EMA software systems and services, and to support the software engineering technology and interoperability efforts of SEC.
