Initial capital and contingency reserves dominate — major one-time costs are PER-3257 construction, tunnel works and large contingency/insurance reserves; recurring costs (~$4.7M/yr) are driven by staff wages, security, legal/cover operations and logistics for secure transfers.

Confidence Notes
Estimates are midpoints of wide provided ranges; large uncertainties stem from negotiation outcomes with the Holy See/City of Rome, archaeological surprises during excavation, and the scale of required insurance/escrow for priceless frescoes. Recurring staffing/logistics estimates are better-defined but still variable.
