Archive room: mobile shelving for the father and mother archive

Planned (October 2026, user): the archive in the office gets mobile
archive shelving, A-Z Solutions (Vienna) as the reference
(a-z-solutions.eu, checked October 2026: hand wheel or electric drive,
lockable, rails need early floor planning; no published prices).

+### Archive room: mobile shelving
+
+Planned (October 2026): the archive in the office is fitted with **mobile
+archive shelving**, carriages on floor rails that close up into one block
+and open a single aisle where it is needed. The reference is A-Z
+Solutions' archive shelving (Vienna; fahrbare Archivregale,
+https://www.a-z-solutions.eu/buero-archiv/archivregale, checked October
+2026): hand wheel or electric push-button drive, optional front panels,
+lockable, and the vendor asks to be involved early because the rails set
+requirements on the floor and the room layout. Prices are not published.
+
+**What it holds.** The father and the mother of every side (decided
+October 2026, [galvanics](equipment/galvanics.md)): 4 parts per title,
+about 1,200 to 2,400 a year at full capacity, in protective sleeves,
+standing in labelled boxes. Also paper records that have to be kept as
+originals. A reference pressing of every title could go here too; that is
+a proposal, not decided.
+
+**Size, estimates.** A 12" father or mother grows on a 14" lacquer: about
+35 cm across, 0.25 mm thick, ~9.6 dm² ([plant
+operation](plant-operation.html) and galvanics figures), so about 0.2 kg of
+nickel. In a sleeve with a separator, assume ~3 mm of shelf per part:
+~330 parts and ~75 kg per shelf metre, on 400 mm deep shelves with ~400 mm
+clear height, five levels to ~2.2 m. In the Payap scenario's office the
+archive is a ground-floor room of about 4 × 5.75 m
+([site candidates](site-candidates.md)). With the rails along the long
+side it takes two fixed single-sided runs, four double-sided carriages
+about 3 m long and one ~0.9 m working aisle: ~150 shelf metres, roughly
+50,000 parts, which is 20 years or more of fathers and mothers at full
+capacity. Static shelving with an aisle between every pair of runs
+would hold about 60 % of that.
+
+**What it asks of the building.**
+
+- **Floor load.** Fully loaded, a double carriage carries about a tonne
+  per metre of length: ~11 kN/m² under the shelving block and ~6 kN/m²
+  averaged over the room (estimates), above an office floor. The archive stays on the ground slab, and
+  that slab keeps the full rating if the slab is zoned lighter under
+  offices ([phase 1 RFQ](finance/phase1-construction-rfq.md)).
+- **Rails.** Set into the floor screed during fit-out, or on a raised
+  floor ramped at the door, so the shelving layout and the rail positions
+  are fixed before the floor finish. Rail type, depth and floor flatness
+  tolerance come from the shelving supplier.
+- **Drive.** A geared hand wheel with an aisle lock is enough for a room
+  one or two people use and has nothing to fail; electric drive is an
+  option, not a need.
+- **The room around it** stays as above: clean-agent gas suppression
+  (the suppression designer confirms the agent reaches into the closed
+  carriage block), climate control with the archive in the tightest
+  monitoring tier ([digital factory](digital-factory.md)), a water-leak
+  sensor along the rails, lockable carriages behind the room's access
+  control.
+- **Locations.** Every box carries a barcode and every position an
+  address (carriage, face, level, slot); the factory application records
+  each part's archive location there, so a repress order says which box
+  to pull.
+
+**Open points.**
+
+- **Quotes:** A-Z Solutions and a Thai or regional mobile-shelving
+  supplier against the same spec (carriages ~3 m, five levels, 400 mm
+  shelves, at least ~100 kg per shelf level per metre, geared hand wheel
+  with aisle lock, central lock, rail embedding detail, delivery and
+  installation in Chiang Mai). Steel shelving shipped from Austria is
+  heavy, so the A-Z system is the reference spec rather than the default
+  buy.
+- **Storage format:** sleeves, boxes, passivation and humidity for
+  archived nickel parts, from the galvanics vendors
+  ([open questions](equipment/galvanics.md#open-questions-for-the-quotes)).
+- **Two compartments:** with fathers and mothers in one room, one event
+  can take both. Keeping the fathers (rarely pulled) in a second fire
+  compartment or off site, and the mothers (pulled for every repress) in
+  this room, would meet the off-site point above.
