ICD-705 Controlled Spaces Modernization and Sustainment Program
Osan Air Base, Republic of Korea
U.S. Army Corps of Engineers – Far East District
DISCLAIMER: This Sources Sought is issued solely for market research/intelligence and acquisition planning. It is not a solicitation, Request for Qualifications, or commitment to issue a solicitation or award any agreement or contract. No Statements of Qualifications or proposals are requested. Participation is voluntary; the Government will not reimburse response costs and will not accept unsolicited proposals. Responses will inform acquisition strategy, industry capability assessment, and project delivery options. Responding does not affect eligibility for any future solicitation.
THE OPPORTUNITY
The U.S. Army Corps of Engineers, Far East District (USACE FED) invites industry partners to help shape the acquisition strategy for a high-priority modernization and sustainment program involving ICD-705 controlled spaces at Osan Air Base, Republic of Korea. The Government is evaluating an innovative Progressive Design-Build (PDB) delivery method executed through an Other Transaction Agreement (OTA) under 10 U.S.C. § 2808a.
This approach enables early contractor involvement, collaborative design development, open-book pricing, and flexible risk allocation—advantages particularly valuable for complex, security-sensitive work performed in an active overseas operational environment with unique host-nation and ICD-705 constraints. The Government has not made a final acquisition strategy determination and seeks candid industry input on the benefits, limitations, risks, and commercial terms of a PDB OTA compared with traditional design-bid-build or design-build approaches.
WHY PROGRESSIVE DESIGN-BUILD / OTA?
ICD-705 controlled spaces, collective protection systems, and HVAC modernization on an active air base present technical, security, operational, and logistical complexities that benefit from early industry engagement. A PDB OTA structure may allow:
The Government is particularly interested in industry’s practical experience with these methods on similar secure or operationally constrained projects, as well as any recommended alternatives that would better achieve mission, schedule, and cost objectives.
PROJECT SCOPE
The program encompasses modernization and sustainment work in two existing facilities at Osan Air Base:
Building A – Collective Protection, HVAC & ICD-705 Modernization
Building B – ICD-705 Conversion & Facility Sustainment
Estimated program magnitude: $60–100 million. Construction funding for both facilities is anticipated for obligation in FY27, subject to availability of funds and applicable approvals. This Sources Sought is the Government’s primary tool to assess industry interest, capability, and preferred commercial practices before finalizing the acquisition approach.
ACQUISITION APPROACH UNDER EVALUATION
Industry feedback will help refine potential agreement structure, project phasing, pricing approach, governance, risk allocation, and other commercial terms.
Potential Phase 1 – Design and Preconstruction
The Government and selected contractor would collaborate to refine project requirements, develop the design, conduct constructability reviews, identify long-lead equipment, evaluate phasing and operational constraints, obtain subcontractor input, develop cost estimates, and mitigate technical and execution risks. Feedback is requested on the design maturity, site investigations, pricing information, and agreement terms needed to establish a reliable construction cost and schedule baseline.
Potential Phase 2 – Construction
Following design development and resolution of key technical and commercial risks, the contractor may be asked to propose a construction price, potentially including a Guaranteed Maximum Price (GMP) if appropriate to the final structure. Any transition to construction would be subject to the terms of the resulting agreement, Government acceptance, availability of funds, and required approvals. The Government seeks practical recommendations for off-ramp provisions, design deliverables, compensation, and transition arrangements should the parties be unable to reach agreement on construction pricing or other required terms.
Alternative acquisition strategies that industry believes would better support the program’s security, technical, schedule, cost, and operational requirements are welcome and encouraged.
INDUSTRY DAY
A Virtual Industry Day is to be determined. The SAM.gov posting will be updated with registration instructions and meeting information when available. Interested firms are strongly encouraged to add themselves to the Interested Vendors List associated with this announcement on SAM.gov to receive timely updates, including Industry Day details.
INFORMATION REQUESTED FROM INDUSTRY
Your candid, detailed feedback is critical to shaping a successful acquisition. The Government’s primary mechanism for obtaining market research is the Industry Questionnaire, which addresses capability and capacity, relevant experience, Progressive Design-Build experience, open-book pricing, technical capabilities (ICD-705, CPS, secure facilities), real estate and construction considerations in the Republic of Korea, schedule, security, risk, governance, and recommended commercial practices.
1. Complete the Industry Questionnaire: Access the Questionnaire Here (https://forms.osi.apps.mil/Pages/ResponsePage.aspx?id=unZN_HzxUEy5p48xY9J1gkOXdBFTSSpJlGbZL6EFB8NUN1FSQ0pXMEE3TU05UzlUQ09QNjNMSjNTTyQlQCN0PWcu) or complete the questionnaire attached.
2. Submit a Capability Statement (not to exceed 12 pages). Include:
The Government especially values recommendations on commercial practices, agreement terms, project phasing, risk sharing, open-book pricing approaches, governance structures, and other considerations that could improve successful execution of this project under 10 U.S.C. § 2808a.
HOW TO RESPOND
Interested firms should complete the Industry Questionnaire and submit any supplemental Capability Statement via email no later than 2:00 p.m. Korea Standard Time (KST), Tuesday, 17 November 2026.
