Who can bid
This solicitation is full and open competition with no set-aside, meaning businesses of any size may compete. Contractors must be registered in the System for Award Management (SAM.gov), hold a valid UEI, and meet any required security clearances, bonding capacity, and past-performance qualifications specified in the solicitation.
Given the overseas performance location, bidders should consider:
- Experience working on U.S. government construction projects in Japan or comparable overseas environments
- Familiarity with NAVFAC, UFC, and military medical facility standards
- Ability to obtain status of forces agreement (SOFA) credentials and comply with Japanese labor, environmental, and import regulations
- Capacity to perform in yen or manage currency fluctuation risk, depending on contract terms
Small businesses without prior NAVFAC or Japan experience may need to subcontract or partner with firms possessing relevant credentials.
How to put together a competitive bid
Understand the contract vehicle. "FY27 Special Project" suggests this may be a task order under an existing IDIQ or multiple-award contract. Verify whether you must already hold the underlying contract to bid—see the solicitation.
Demonstrate relevant past performance. NAVFAC heavily weights experience on military hospital alterations, projects in Japan, and work within restricted-access installations. Document completed projects of comparable complexity, dollar value, and geographic location.
Address the Japan operating environment. Develop plans for: local labor sourcing (Japanese and third-country nationals), material procurement with potential Buy America Act implications, waste disposal per Japanese environmental law, and coordination with base security and medical operations during active-hospital conditions.
Price realistically. Overseas construction involves logistics costs, currency exposure, and extended mobilization/demobilization. Escalation clauses and material-price-adjustment mechanisms may be critical—see the solicitation for permitted terms.
Submit a complete technical proposal. NAVFAC RFPs typically evaluate technical approach, management plan, safety record, small business subcontracting plans, and past performance before price. Missing volumes or forms risk disqualification.
