Expected Level of Effort for Deliverables (Based on ITES-3S):

ITES-4S is expected to be structured similarly to ITES-3S, specifically:

  • Open to Army, Department of Defense (DoD), and Federal agencies
  • Contracts will include firm fixed price, time and materials, and cost plus
  • NAICS Code: 541519: Other Computer Related Services (possible additional NAICS codes)
  • Scope similar to ITES-3S: Cybersecurity Services, IT Services, Business Process Reengineering, Enterprise Design, Integration, and Consolidation, Network/Systems Operation and Maintenance, Telecommunications/Systems Operation and Maintenance, IT Supply Chain Management, IT Education & Training

The Army — specifically Program Executive Office Enterprise Information Systems’ (PEO-EIS) Computer Hardware, Enterprise Software and Solutions (CHESS) — is considering several significant additions to the ITES vehicle, including:

  • Multiple NAICS codes
  • Two sets of suites (high-end vs. low-end)
  • 8(a) set-asides
  • More small-business goals
  • Requirement for vendors to provide additional details on their websites about current partners, subcontractors and the benefits of partnering with them

Based on the prior ITES-3S contract, interested bidders can expect a similar level of effort for the updated ITES-4S. The ITES-3S proposal included:

  • Volume I: Mission Support: 30 pages maximum (Mission Support Forms included)
  • Volume II: Past Performance: Up to three pages per reference (IAW L.9.2.1). No page limit for Adverse Performance Information, Letter of Consent, or PPQ

Of the 187 bids received for the ITES-3S contract vehicle, the Army awarded 135 contracts – 85 to small businesses and 50 to large businesses. The overall contract spend for ITES-3S was more than $741 million as of September 30, 2022, according to the Army.
