The expanded Bofinken article documents a single anonymized rock-cavern civil-defence command centre through design, excavation, two construction stages and operation. It reports about 20 m rock cover, an initial 850 m² / 9,149 ft² room programme, a planned approximately 12 m room width with 2.5 m arch rise, a 25,000 m² / 269,098 ft² site and a two-level concrete inner building evidenced by lower/upper-floor work. It records main and reserve exits, a through-blast/air path, evacuation and ventilation shafts, extensive bolting/mesh/shotcrete, difficult water supply, a 15 m³ internal reserve, CBRN/blast barriers, diesel power for about 30 days, EMP room, telecom and 60 m mast. The exact 1,300 m² / 13,993 ft², 8,500 m³ and 140 m tunnel values used by the dossier do not occur in this source_order 19 text; they occur in the separate archived Bofinken source_order 61.

area_m2: value: 850 m² / 9,149 ft² | scope: initial internal room programme | note: Excludes unspecified spaces; breakdown is 415 work, 175 sleep, 26 toilets, 18 wash, 16 corridors and 200 machine rooms. Not an as-built gross area.; value: 100 m² / 1,076 ft² | scope: surplus space after Type A to Type C reduction | note: The facility was initially designed for about 100 people; surplus later supported reserve functions.; value: 25000 m² / 269,098 ft² | scope: acquired land parcel | note: Site area, not floor area. | height_m: value: 2.5 | scope: planned cavern arch rise | note: Rise of arch, not total internal height and not explicitly confirmed as-built. | span_m: value: 12 | scope: planned room width | note: Pre-design geological recommendation, not an as-built survey. | inner_structure: Two-level reinforced-concrete building within a rock chamber, with concrete floor slabs, walls and barriers, separated protected/unprotected plant areas and accessible interstitial space between rock and building for drainage/inspection. | levels: value: 2 | scope: Bofinken inner building | note: Lower and upper floors are explicitly referenced in construction inspections. | other: value: 20 | unit: m | scope: rock cover above facility roof; value: 15 | unit: m³ | scope: internal water reserve; Main entrance and reserve exit with blast doors are explicit. The through-blast/ventilation tunnel has upper and lower daylight openings, but the article does not consolidate these into a single portal count.; An evacuation rise/shaft, ventilation shaft, antenna boring/mast foundation and generator exhaust route are described; exact shaft count and sections are not safely stated.; Rock stabilization included dozens of roof/portal bolts, mesh, shotcrete, local cast reinforcement and recurring entrance scaling.

amount_sek: 2000000 | price_date: May 1963 estimate | basis: early total facility estimate | scope: Bofinken, one facility | note: Later increased; not an outturn cost.; amount_sek: 3320000 | price_date: 22 May 1964 estimate | basis: total facility estimate excluding radio and telecom equipment | scope: Bofinken, one facility | note: Breakdown: excavation and road 625k; protective barriers 260k; inner construction 1.35m; external sewer 30k; VVS 260k; electrical 330k; design risk 265k; guarding 100k; equipment 75k; water investigation/well 25k.; amount_sek: 4350000 | price_date: October 1964 revised estimate | basis: revised total facility estimate | scope: Bofinken, one facility | note: The article also states building costs of 3.25m in the later discussion; not final outturn.; amount_sek: 415496 | price_date: 1964 accepted bid | basis: rock-excavation contract | scope: Bofinken first-stage excavation | note: Accepted bid, distinct from the 625k excavation-and-road allowance in the total estimate.; amount_sek: 3640000 | price_date: 1968 estimate | basis: second-stage expenditure estimate | scope: Bofinken building, finishes, VVS, power/lighting, telecom and standby power | note: A phase estimate; relationship to earlier total estimates must be reconciled before escalation.; amount_sek: 58145 | price_date: 1967 final land cost | basis: land acquisition | scope: approximately 25,000 m² / 269,098 ft² Bofinken site; amount_sek: 80000 | price_date: 1979 proposal | basis: entrance-rock concrete stabilization | scope: Bofinken maintenance | note: Maintenance proposal, not original construction.

system: blast, CBRN and EMP protection | evidence: 20 m rock cover; reported 10 atö nuclear blast resistance and 20 atö protection class; blast/gas barriers, gas locks, stone filters, decontamination showers, protected cables and a dedicated EMP room. | scope: Bofinken; system: power | evidence: Grid transformer ultimately 200 kVA, diesel standby generation with about 30-day aggregate endurance, oil tank, automatic control, emergency lighting batteries and separate protected air/exhaust paths. | scope: Bofinken; system: water, sewage and drainage | evidence: Multiple unsuccessful internal borings, external deep well and long feed, pumps, 15 m³ reserve, internal water tank, three-chamber sewage well, drainage and groundwater pumps; water scarcity forced air-cooled generator design. | scope: Bofinken; system: ventilation and cooling | evidence: Improved protected ventilation, filters, rapid valves, cooling plant and separate gas-protected air paths; construction records show complex commissioning and condensation/drainage issues. | scope: Bofinken; system: communications | evidence: Telephone exchange and line-taking system, radio, internal alarm/loudspeaker, protected cable routes and a 60 m radio mast; the selected off-site telecom connection was estimated around 12 km. | scope: Bofinken; system: habitability and mission | evidence: Designed initially for about 100 staff, with sleeping, sanitation, sick room, command/orders rooms, pantry and about one week of reserve food; later accommodated additional reserve/local-command roles. | scope: Bofinken

published cavern volume and tunnel geometry from the separate archived capture; two-level inner concrete building and barrier system; site-specific bolting, mesh, shotcrete and recurring unstable entrance rock; blast/CBRN/EMP doors, filters, locks and protected penetrations; deep-well exploration, external water route, tank, pumps, sewage and drainage; 30-day diesel power, cooling, oil storage and emergency batteries; 60 m mast, long telecom connection and protected communications; long, staged construction and commissioning complexity

One anonymized facility. All project estimates and work packages are Bofinken-specific, but estimates are from different dates/stages and should not be summed without reconciliation. The linked dossier also merges the separate archived source_order 61, which supplies exact as-described geometry absent from source_order 19.

Revised upward after source-specific review.

reconciliation of 850 m² / 9,149 ft² planned programme with 1,300 m² / 13,993 ft² figure in archived source; as-built drawings and gross/net area by level; tunnel and shaft sections and consolidated external-interface count; as-built concrete and reinforcement quantities; rock-support quantities and present condition; final actual construction cost and phase-cost reconciliation; as-built external water, sewer and telecom route lengths; post-1983 repair costs and current condition

The dossier combines evidence from source_order 19 and the archived source_order 61; provenance should show which article supports each quantity.; The dossier's displayed SEK 5.5m/1972 historic amount is not stated in source_order 19 and appears to come from source_order 61; source 19 instead gives a sequence of estimates and phase budgets.; Early 850 m² / 9,149 ft², 12 m width and 2.5 m arch rise are design-stage evidence, not necessarily as-built geometry.; Cost estimates from 1963, 1964 and 1968 overlap or supersede each other and must not be added blindly.; The exact location is deliberately anonymized.
