One-time capital costs are dominated by construction of a continuous 3 m-thick titanium wall and associated civil works, producing an estimated upfront cost of roughly $4.04 billion. Annual operating costs (security, staff, maintenance, legal and logistics) are ~ $8.28 million/year, with incident scenarios capable of adding millions to billions in a given year.

| Role | Count | Notes |
|---|---|---|
| Security Officer / Guard Force | 30 | [#7] 24–40 guards typical; estimated 30 FTEs to provide 24/7 coverage, supervisors and leave/sick coverage (salaries included in staff_wages). |
| Research Scientist / Technician | 8 | [#14] Small research team (6–10 FTEs) to analyze samples, maintain instrumentation and run experiments; estimated 8 FTEs (salaries included in staff_wages). |
Confidence Notes
Containment requirements (notably the explicit 3 m titanium wall) are specified in the brief, allowing a bounded capital estimate, but major uncertainty remains in titanium pricing, fabrication logistics, and the likelihood/scale of breach scenarios; recurring costs are better constrained by staffing and maintenance estimates.
