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 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.

One portal package per 4000 usable m² / 43,056 ft², subject to a 1-package minimum. · Reviewed base modelCast inner structures and linings, kept separate from excavated rock and reinforcement mass.
The 1985 table's reported shelter area is held fixed as usable area; concrete shell quantities require archetype assumptions. 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.

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. The article is a 15-shelter programme history and 1985 schedule, and the complete mapping links one dossier for every table row. Across all 15 large shelters it reports 63,450 m² / 682,970 ft² and 53,896 places; the units comprise nine rock shelters and six r…

Central quantities × current installed-rate screen.
Not yet probability-weighted. The current legacy concept contingency remains separate.
22% applied to the direct-work screen.
Raw model SEK 222.9m · rounded for Confidence E.
Transitional limitation. SEK 37,900,000 is still a blanket concept contingency, not probability-weighted expected risk. This is why the amount is labelled provisional. The audited population shelter concrete WBS remains the central scope ledger.
The row is a named physical facility extracted from a 1985 class table; the printed type is concrete but exact burial/shell geometry is not published.

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.
MCF's knowledge-document register establishes civil-shelter system scope but supplies no project prices; all three unit rates are transparent screening assumptions.
Public sources establish specialized tested products but not project prices.
No lifecycle dates were established from the public source.
