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 describes one anonymous modern underground concrete county command post built in 1998, one of fifteen similar facilities built nationally during the 1990s, and comprehensively renovated in 2014. About 60 people can work there. It is intended to su…

Transitional limitation. SEK 15,118,500 is still a blanket concept contingency, not probability-weighted expected risk. This is why the amount is labelled provisional. The audited command buried WBS remains the central scope ledger.
