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 preserved 1970s forward rescue-unit personnel shelter and explicitly says this example had no vehicle shelter. The discussion of five personnel out of a 20-person fire service is illustrative, not a stated design capacity. No area, sh…
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 31.3m · rounded for Confidence E.
Transitional limitation. SEK 5,322,735 is still a blanket concept contingency, not probability-weighted expected risk. This is why the amount is labelled provisional. The audited rescue shelter WBS remains the central scope ledger.
The article confirms a personnel-only shelter and explicitly excludes vehicle shelter.

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.

| Subject | Claim | Value | Date | Evidence | Certainty |
|---|---|---|---|---|---|
| facility claim | Claim | This visited site used a purpose-built personnel shelter for the forward unit. | — | B004 | Reported |
| facility claim | Claim | The site had personnel protection only; it had no vehicle shelter inside or adjacent to the facility as described. | — | B004 | Reported |
| facility claim | Claim | The article reports construction in the 1970s. | — | B007 | Reported |
| facility claim | Claim | The article described it as a preserved example and one of few then still in good condition. | — | B007 | Reported |
| class context claim | Claim | Forward units could use purpose-built shelters, existing shelters such as shelter garages, and sometimes internal or adjacent vehicle protection. | — | B004 | Reported |
| class context claim | Claim | The wartime concept dispersed rescue-service personnel across a municipality to reduce dependence on a vulnerable main fire station and improve local response after infrastructure damage. | — | B005 | Reported |
| class context claim | Claim | The article says crews worked two, possibly three, shifts at a time; wartime-assigned personnel would be led by rescue-service professionals. | — | B006 | Reported |
| current-state claim | Claim | At publication the facility was described as preserved and in good condition. | — | B007 | Reported |
