The article provides useful storage-cavern geometry: a little over 30 m shock tunnel; one main 60 m by about 20 m chamber with maximum height about 3 m; and two smaller chambers each roughly half the main size, implying about 2,400 m² / 25,833 ft² of chamber footprint. It also describes one truck-loading entrance, exhaust ventilation, a heavy blast door and rolling concrete barrier, a freestanding sheet-metal/timber inner structure, active water dripping to coarse-gravel drains, and a separate ammunition concrete caisson at an undisclosed place.

published: shock tunnel slightly over 30 m; main chamber 60 m by about 20 m by maximum 3 m high; two chambers each about half main size; approximately 2,400 m² / 25,833 ft² inferred total chamber footprint; one angled protected entrance/loading shed | not_published: exact smaller-chamber dimensions and heights; connecting-tunnel geometry; crown/overbreak and support; inner-building dimensions; ammunition-caisson location and size

truck exhaust extraction beneath loading dock; heavy blast door; rolling concrete blast barrier; sheet-metal/timber inner enclosure; coarse-gravel drainage channels; owner-added solar, wind, batteries, dehumidification and generator are post-military additions

chamber and tunnel volume; support surface and water condition; drainage/dehumidification; blast door and rolling barrier; loading interface and exhaust; basic storage fit-out

One anonymous storage cavern; the separate ammunition caisson is not dimensioned and should be excluded or separately scoped.

Derive chamber clear volume from the published dimensions and separate access/crown/overbreak; price rock support by exposed area; add water inflow, drains and dehumidification explicitly; separate blast door and rolling barrier; exclude owner-added renewables and unlocated ammunition caisson unless separately scoped

exact smaller-chamber dimensions; cross-sections and support class; water inflow/hydro survey; inner-enclosure schedule; blast-door/barrier specifications; loading/exhaust equipment schedule

water is visible in the source but absent as a WBS line; protection interfaces are compressed into portal allowance; source-era versus owner-added systems need stronger provenance badges
