Functional recreation of the documented facility in Sweden using current construction methods and 2026 prices, preserving the documented capacity, protection, autonomy and redundancy. Ex VAT; excluding land, financing, remediation, classified mission equipment and data-centre hardware.
Provisional audited central concept screen; expected-risk calibration is pending. It is not yet a risk-adjusted expected cost.
Method, scope and confidence →Published, calculated and proxy dimensions are deliberately separated. Missing evidence stays visible instead of becoming zero.
Rock in place removed before bulking; the excavation-pricing quantity.
Internal airspace; not the amount of rock removed.
Blasted material after bulking; the haul and disposal quantity.
These cubic metres are not interchangeable.
Usable, floor or footprint area; the label is preserved because these are not always interchangeable.

No usable quantity in the reviewed source · Evidence gapBlasted material after bulking, or its handled mass. No swollen cubic metres are inferred when only tonnes are modelled.
No rock mass-handling scope applies to the audited morphology. · Audited morphologyLength alone is insufficient; a costable tunnel also needs width, height or cross-sectional area.
No tunnel geometry applies to the audited morphology. · Audited morphologyPublished chamber or arch geometry used to test volume and support assumptions.
No usable quantity in the reviewed source · Evidence gapRock surface requiring bolts, mesh or shotcrete, preferably measured in square metres.
Rock-support surface does not apply to this audited morphology. · Audited morphologyCounts and dimensions of access, transfer, utility and emergency interfaces.
Archetype portal/escape count. · Reviewed base modelCast inner structures and linings, kept separate from excavated rock and reinforcement mass.
Proxy for a larger protected BasC with command, reserve power, BC protection and rest space. Archetype concrete factor is 2 m³ per usable m². · Reviewed base modelGroundwater, inflow, drainage, pumping and moisture-control evidence affecting construction and operation.

Different specifications receive different estimates; they are not used as the upper and lower limits of one answer.
Preserves documented capacity, protection, autonomy and redundancy using current construction methods.
Requires a modern structural, fire, protection and supplier performance brief.
Requires IT load, cooling topology, grid capacity, redundancy and autonomy. Server hardware is excluded.

Ex VAT; excluding land, financing, remediation, classified mission equipment and data-centre hardware. Eskilstunabasen was a distributed Bas 60 attack base built 1960–1962 and converted toward Bas 90 from 1987, with a main runway, two built remote short runways, taxi/aircraft roads, alert and service areas, multiple dispersed fuel tanks, shelters, a buried con…

The three inputs most likely to move the current screen.
These deterministic stress cases simultaneously vary quantities, rates, scope allowances and contingency. They are not confidence intervals and no longer serve as the headline answer.
Links support a rate, scope boundary or method. Context-only sources are not represented as quotations.
Public ready-mix material check only; installed underground rates require RFQ.
Public retail material check only; cutting, bending, fixing, waste and underground logistics require RFQ.
