+# Project Scale: Rough Numbers
+
+One-page sizing of the whole project. Everything here is a planning
+estimate derived from the session's vendor data and standard ratios;
+figures marked "estimate" have no vendor confirmation yet. Update this
+page as real quotes and the site decision land.
+
+## Production capacity
+
+| Phase | Fleet | Rough output |
+|---|---|---|
+| Launch | 1 semi-auto press (Newbilt Single), 1 shift | ~90,000 to 135,000 records/yr |
+| Duplex | 2 semi-auto presses, 1 to 2 shifts | ~300,000 to 600,000 records/yr |
+| Mature | 2 semi-auto + 2 automated (50/50 fleet), 2 shifts | ~1.0 to 1.5 million records/yr |
+
+Basis: the automated AD12 presses ~140 records/hour each (vendor datasheet);
+semi-automatic throughput is unpublished, assumed 60 to 80 records/hour per
+press with operator handling (estimate); 16 h/day, 300 days/yr, with
+realistic overall effectiveness of 60 to 70% applied. The theoretical
+ceiling of the mature fleet at 100% uptime is roughly 1.9 to 2.1 million
+records per year.
+
+## Building
+
+| Zone | Rough area |
+|---|---|
+| Semi-auto press hall (Newbilt Duplex spec) | ~200 m² |
+| Automated press zone | ~100 to 150 m² |
+| Galvanics clean room + water treatment + chemical storage | ~80 to 150 m² |
+| Mastering and cutting room | ~40 to 60 m² |
+| Stamper prep | ~30 m² |
+| Packaging + finished goods warehouse | ~300 to 500 m² |
+| Utility rooms (boiler, compressor, chiller, electrical) | ~100 to 150 m² |
+| Offices, QC/listening, archive, IT, entrance | ~150 to 200 m² |
+| Circulation, walls, misc | ~150 to 250 m² |
+| **Total under roof** | **~1,200 to 1,700 m²** |
+
+The HVAC budget in the utilities CSV already assumes ~1,500 m² conditioned.
+Single story throughout: all heavy equipment needs ground-slab floor
+loading (multiple tons per m²).
+
+## Land: factory plot
+
+Industrial plots typically allow 50 to 60% building coverage, and the site
+needs truck access and turning, parking, the outdoor cooling tower, the
+separated BESS enclosure, possible ground-mount solar, and expansion room.
+
+- Minimum workable: **~4 rai** (6,400 m²)
+- Comfortable with expansion and ground-mount solar: **~6 to 8 rai**
+  (9,600 to 12,800 m²)
+
+Separate asset: the **60 rai** forestry-classified parcel for coppice
+fuelwood (see [biomass](biomass.md)), pending its title check. It is a fuel
+plantation, not a factory site candidate unless the classification allows
+conversion, which forestry land generally does not.
+
+## Electrical scale
+
+| Load | Rough figure |
+|---|---|
+| Pressing machinery (semi-auto line + 2 automated presses) | ~70 to 80 kW installed |
+| Process chiller (250 kW cooling) | ~80 to 125 kW electrical |
+| Whole-factory HVAC | ~100 to 200 kW peak (estimate) |
+| Electric steam boiler (if chosen over biomass/LPG) | ~300 kW |
+| Compressed air, lighting, IT, misc | ~30 to 50 kW |
+| **Plant peak demand** | **~300 to 450 kW without electric boiler; ~600 to 750 kW with it** |
+
+Grid connection: a medium-voltage connection with a transformer in the
+**500 to 1,000 kVA** class from PEA, sized by the boiler decision.
+
+## Solar and storage
+
+- Roof of a ~1,500 m² building fits roughly **150 to 200 kWp**; reaching the
+  illustrative 300 kWp in the utilities CSV needs carport or ground-mount
+  on the plot (about 1 rai of ground per additional 100 kWp, estimate)
+- Northern Thailand yield ~1,400 to 1,500 kWh/kWp/yr, so 300 kWp produces
+  roughly **420 to 450 MWh/yr**
+- Plant consumption at mature two-shift operation: roughly **1,000 to
+  1,500 MWh/yr** without electric steam, up to **~2,500 MWh/yr** with it
+  (estimate), so 300 kWp covers on the order of **20 to 35%** of
+  consumption; a bigger array shifts that up
+- Battery: **271 kWh** Gobel stack (peak shaving and ride-through, roughly
+  two to three hours of the chiller's electrical draw)
+
+## Steam and fuel
+
+- Boiler: **400 kg/h at 10 bar / 180 °C** (~300 kW thermal)
+- If biomass: **~350 to 400 t/yr** air-dry wood at mature operation, of
+  which the 60 rai coppice could supply **~80 to 135 t/yr**
+- If LPG: **~2.5 to 5 t** bulk tank on site (no gas pipeline in the North)
+
+## People
+
+Rough mature-operation headcount (estimate): 4 to 6 press/finishing
+operators per shift, 2 to 3 galvanics, 1 to 2 mastering/cutting engineers,
+1 to 2 QC, 2 maintenance, 3 to 5 admin/sales/logistics. Roughly **15 to 25
+people** across shifts at maturity, fewer than half that at launch.
+
+## Money (cross-references)
+
+- Newbilt semi-auto line: **~€200,500** (2024 quote, expired, in
+  [pressing-line](equipment/pressing-line.md))
+- Thai-sourced utilities, HVAC, racking, solar, BESS baseline: **~24M to
+  42M THB** (~€630k to 1.1M), detail in the
+  [utilities CSV](finance/utilities-investment.csv)
+- Not yet priced: automated presses (indicative ~$340k each, unverified),
+  galvanics line, mastering/cutting room, metrology, building
+  construction/fit-out, land
