Quick Summary

The Department of Homeland Security (DHS), Office of Procurement Operations (OPO), Information Technology Acquisition Center (ITAC) intends to award a Sole-Source Justification (SSJ) for Architecture, Development, Engineering, and Management Services (ADEMS). This is a follow-on order to be awarded to ECS Federal, LLC, valued at an estimated $24.1 million, for a 12-month period. The purpose is to ensure continuity of highly specialized technical contractor support for the Office of the Chief Information Officer (OCIO) until a new competitive solicitation under the ADaPTS 2.0 BPA can be issued.

Scope of Work

The ADEMS services provide highly specialized technical contractor support for the OCIO. This includes application analysis, architectural design, engineering, development, maintenance, and support. Expertise is required in platforms such as Dynamics 365, Power Platform, SharePoint, Office 365, Azure, Dataverse, Confluence, Jira, and ServiceNow. The scope also covers agile software development, project management, technical architecture, continuous integration, testing, configuration management, ongoing operations and maintenance, and cloud migration.

Contract & Timeline

  • Type: Sole-Source Follow-on Order under the Multiple-Award Schedule Program.
  • Intended Awardee: ECS Federal, LLC.
  • Period of Performance: 12 months, from April 20, 2026, to April 19, 2027.
  • Estimated Value: $24,107,321.13 (Independent Government Cost Estimate - IGCE).
  • Published: May 4, 2026.

Set-Aside

This is a Sole-Source Justification; therefore, no set-aside applies. The agency plans to competitively solicit future requirements once the ADaPTS 2.0 vehicle is awarded.

Evaluation

As this is a sole-source justification, there are no proposal submission or evaluation criteria for external bidders. The contracting officer has determined the proposed order represents the best value, considering price and administrative costs. GSA has negotiated fair and reasonable pricing rates, and the contractor's labor mix and level of effort will be compared to the IGCE to ensure reasonableness.

Additional Notes

This action is authorized under FAR Class Deviation 25-20 and GSAM/R 538.7104-3(b)(iii). Market research was conducted, and the agency intends to post this sole source requirement at the Government-wide Point of Entry (GPE).
