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.
No usable quantity in the reviewed source · Evidence gapGroundwater, 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.

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. The article supports one 1940 hilltop machine-gun position of the Lindén/kg-hat type, with a cupola above shelter and crew accommodation. It describes bomb/artillery resistance qualitatively and notes a 2006 restoration, but gives no dimensions, material quan…
Audit revision sweden-replacement-audit-2026.08.15. The central WBS below incorporates the 61-article review. The former deterministic low/base/high cases remain available only as sensitivities and revision history.

Not yet probability-weighted. The current legacy concept contingency remains separate.
22% applied to the direct-work screen.
Raw model SEK 7.1m · rounded for Confidence E.
Transitional limitation. SEK 1,200,000 is still a blanket concept contingency, not probability-weighted expected risk. This is why the amount is labelled provisional. The audited small bunker WBS remains the central scope ledger.
One documented Lindén-type machine-gun position; dimensions are not published.

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.
Provider-listed starting prices include VAT. They are divided by 1.25 for an ex-VAT sanity check and used only for compact bunker units.
