Observations- och mättjänst

The article provides a useful micro-facility type standard. An observation point comprises a personnel shelter plus a protected two-person lookout/post and an instrument position. The personnel shelter is about 12 m² / 129 ft² for at least three and at most six people. Its construction could be an existing normal shelter, freestanding shelter, rock shelter or fragment/radiation shelter depending on location. Lookout-to-shelter travel should not exceed two minutes; separate observation sites should be at least 2 km apart. Göteborg had twelve observation sites, three newly built freestanding sites in 1961. The group cost for those three was estimated at SEK 150,000 in 1961 (SEK 1,655,048 in 2016 money).

area_m2: value: 12 m² / 129 ft² | scope: personnel shelter archetype | evidence: Explicitly reported as approximately 12 m² / 129 ft² for 3–6 people. | inner_structure: Possible forms include an existing normal shelter, freestanding shelter, rock-fixed shelter or fragment/radiation shelter.; Lookout/post should, where possible, have pressure resistance comparable to a reinforced-concrete framed building. | other: Lookout/post capacity: two people.; Personnel shelter capacity: minimum three, maximum six.; Lookout-to-shelter movement time: no more than two minutes.; Spacing between two observation sites: at least 2 km.; Explosions-point instrument should preferably be adjacent to the lookout and no more than 200 m away.; Dense measurement-network spacing: generally 5–10 km; instrument-use distance limits of 10–15 km from a town centre, up to about 20 km for Stockholm, Göteborg and Malmö.

amount_sek: 150000 | price_year: 1961 | equivalent_sek: 1655048 | equivalent_year: 2016 | scope: aggregate estimated cost of three new freestanding observation sites in Göteborg | note: This is a group total. Do not assume equal per-site costs or treat it as the cost of all twelve sites.

Telephone and radio usable from both shelter and lookout.; Heating, bunks and assigned hand tools.; Observation, radiological/gas measurement instruments and explosions-point indicator.; Weather protection at the lookout.; Normal-shelter protection value of at least 3 atö where building-shelter duty applied; otherwise fragment protection and residual-radiation protection factor 100 as the stated minimum.
