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 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 usable quantity in the reviewed source · Evidence gapPublished 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.
No representative facility construction cost selected
General purchasing-power comparison—not a construction quote
Broad BKI proxy—not a bunker-specific rebuild price
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 is principally a STRIL/styrdata systems history. It supports procurement of 41 FMR-10 transmitters, a three-person wartime operating team per node, unmanned peacetime operation, seven equipment racks, antennas/transmission equipment and standby ge…
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.
Direct works + owner / design / investigation + legacy concept contingency
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 3.28bn · rounded for Confidence E.
Transitional limitation. SEK 558,466,125 is still a blanket concept contingency, not probability-weighted expected risk. This is why the amount is labelled provisional. The audited telecom protected WBS remains the central scope ledger.
The archive record is a 41-site class/programme, not one physical bunker.

The workbook publishes one revised central schedule. Its prior low and high stress cases are retained only under sensitivities; no line-level probability distributions are implied.

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 sources establish specialized tested products but not project prices.
The cited large-tunnel electrical award is a macro systems cross-check only; node package values are assumptions.
