TOTAL ENGINEERING AND INTEGRATION SERVICES (TEIS) IV On-Ramp Opportunity
DEPT OF DEFENSE.DEPT OF THE ARMY.AMC.ACC.ACC-CTRS.ACC-APG.W6QK ACC-APG CONTR CTR · Response deadline: Fri, 30 Oct 2026
What the government is buying
The Army Contracting Command at Aberdeen Proving Ground (ACC-APG) is conducting an on-ramp opportunity for Total Engineering and Integration Services (TEIS) IV. This is a partial small business set-aside under the TEIS IV multiple-award contract vehicle, which supports the government's need for professional engineering and systems integration services.
TEIS contracts typically cover a broad range of engineering support, including systems engineering, technical integration, test and evaluation, and related professional services for Army communications and electronics systems. Fort Huachuca, Arizona, serves as the primary place of performance—a major Army installation focused on military intelligence and network operations, which aligns with the technical nature of this requirement.
An "on-ramp" opportunity means the government is adding new vendors to an existing multiple-award indefinite-delivery/indefinite-quantity (IDIQ) contract. This allows additional qualified small businesses to compete for task orders that would otherwise be restricted to existing contract holders.

Who can bid
This opportunity is partially set aside for small business concerns under NAICS 541512 (Computer Systems Design Services), which carries a size standard of $34.5 million in average annual receipts. Only firms meeting this size standard and registered in SAM.gov as small businesses should pursue this opportunity.
The "partial" set-aside designation is significant: the government may award some portions to small businesses while reserving other portions for full and open competition, or this may represent a small business pool within a larger unrestricted contract structure. Firms should verify their small business status is current in SAM.gov and that their socioeconomic certifications (if any) are accurate.
Given the on-ramp nature of this procurement, competitive range and award decisions may be influenced by the government's need to maintain a diverse vendor pool alongside existing contract holders.
How to put together a competitive bid
For TEIS IV on-ramp proposals, focus on these elements:
Demonstrate relevant past performance. The government will evaluate your track record performing similar engineering and integration services for federal clients. Prior Army or DoD work at Fort Huachuca or within communications-electronics domains carries particular weight. Document specific contract values, periods of performance, and customer contact information.
Highlight technical capabilities in systems integration. NAICS 541512 covers computer systems design, but TEIS requires broader engineering competencies. Detail your methodologies for requirements analysis, architectural design, interface management, verification and validation, and lifecycle engineering support.
Address security clearances and personnel qualifications. Work at Fort Huachuca frequently requires cleared personnel. Identify your cleared workforce and your ability to obtain interim clearances for critical positions.
Emphasize cost competitiveness for IDIQ vehicles. Multiple-award contracts are awarded based on demonstrated capability and competitive pricing at the ceiling level; task order competitions determine actual revenue. Structure your pricing to be competitive while sustainable across potential task order scenarios.
Submit complete proposals by the tight deadline. With only three days between posting and response deadline, this opportunity may represent a streamlined on-ramp with limited proposal preparation time. Prioritize required sections and ensure compliance with page limits, format instructions, and mandatory representations.
