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.

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 gapRock in place removed before bulking; the quantity used to price excavation.
The audited morphology is not a rock-excavation class. · Audited morphologyInternal air or chamber volume. It is not solid excavation without overbreak, access and support geometry.
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.
No usable quantity in the reviewed source · Evidence gapCast inner structures and linings, kept separate from excavated rock and reinforcement mass.

Different specifications receive different estimates; they are not used as the upper and lower limits of one answer.

Requires a modern structural, fire, protection and supplier performance brief.
Requires IT load, cooling topology, grid capacity, redundancy and autonomy. Server hardware is excluded.

Scope lock. 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. Whole-site history of two wartime fields about 2 km apart that merged into Fält 8/9 and were upgraded to Bas 60. Direct quantities include three 700 m runways at Fält 9, a later 2,000 m concrete runway, 38 initial revetments, 20 buried 100 m³ fuel tanks, 18 l…

Transitional limitation. SEK 177,156,250 is still a blanket concept contingency, not probability-weighted expected risk. This is why the amount is labelled provisional. The audited airbase system WBS remains the central scope ledger.

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 material establishes specialized systems but no prices. Package values are assumptions and must not be read as classified equivalence.
