User, October 2026: the Duplex sketch is not to scale, check it against
the documents; the fire water tank is too small.
Model (changed live in the open FreeCAD 26.3 document):
- both Duplex cells rebuilt in the sketched arrangement at the documented
sizes: presses 0.95 m square (0.9 m2) turned 45 deg, EX 50 0.5 x 1.0 m
(0.5 m2), EX 35 0.4 x 0.8 m and trimmer 0.6 x 0.6 m (estimates),
operator position marked; 0.6 to 0.8 m between machines;
- fire water: the ~25 m3 yard tank replaced by the facility-security
planning tank, 9 m x 4 m (254 m3 gross, ~200 m3 usable), new params
fw_dia, fw_h, fw_x, fw_y, at the front by the access road, outside the
production yard, on a ring foundation, with a pump house (duty electric,
standby diesel, jockey); the yard process water tank is now the 5 x 3 m
raw water tank of the phase 1 RFQ.
Docs: site-candidates (cell, raw water, fire water bullet),
facility-security (the Payap model draws the tank; 6 m racking and twice
the floor area make ~200 m3 a floor there).
User, October 2026: ground-floor colour store plus outdoor silos; a
two-storey block at the east end with packaging below and printing plus
print and packaging stock above; in-house printing not decided, so the
print room is reserved only.
Model (rebuilt live in FreeCAD 26.3 after checking a copy of the saved
file for user edits; parametric check plot 150->160 m and upper floor
3.8->4.2 m passed):
- factory 128 x 25 m, plot 150 m (14.1 rai), corridor 98 m, fire wall
at 106 m, new params crane_x (runway end = press hall end, 92 m) and
mezz_z (+3.8 m);
- galvanics open to stamper prep (wall kept only on the material area
and electrical side);
- colour store 10 m bay (~180 m2): two racking rows, ~100 pallet
positions on 4 levels (estimate), weighing and mixing, vacuum
conveying station; indoor silos replaced by regrind bins;
- 4 outdoor PVC silos (2 black, 2 standard colours, ~50 m3 each,
estimate), big-bag filling station, buried conveying lines;
- finishing and print block 14 x 25 m: ground floor trim, optical
inspection, QC, packaging (tables, shrink wrap, pallet wrapper), stair
(Arch Stairs) and goods lift; upper floor print room (reserved), print
stock, packaging materials.
New docs/cnx_vinyl_parametric_payap-block.png with both block levels.
Docs: site-candidates Payap section rewritten (areas ~3,800 m2 under
roof, ~4,630 m2 of floor), crane doc (98 m corridor, runway ends at the
press hall), README bullet and layout line.
User, October 2026: the office building also houses several showers, a
changing room, toilets and a canteen; the office area itself about
150 m2; the building can be multi-storey.
Model (office rebuilt live in FreeCAD 26.3; factory and site untouched):
- 32 x 15 m on two storeys (off_storey 3.6 m), ~960 m2 of floor, Arch
Stairs plus a lift, first floor slab with the stair and lift void;
- ground floor: reception and lobby (entrance and link door), canteen
~40 seats with kitchen and servery, changing rooms women and men with
4 showers each and lockers, toilets, mastering and cutting (acoustic
lining), listening room, archive;
- first floor: offices 147 m2 (16 desks), training room (Payap
programmes), meeting room, IT and server, toilets, pantry, flexible
room;
- factory staff entry relabelled "PPE, WC" (changing is in the office).

Docs: site-candidates Payap section (office bullet, staff entry, area
~3,400 m2 footprint / ~3,880 m2 floor), README bullet and layout line.
User, October 2026: the factory is too small and needs room to grow
(possibly ten more Classics), one shared hydraulic and air supply, water
treatment perhaps in a separate building connected to the galvanics lab,
and a fully equipped workshop (maintenance tools, 3D printers, maybe a
lathe and a small CNC mill).
Model (rebuilt live in FreeCAD 26.3, BIM objects, Params-driven,
parametric check plot 135->145 m and factory 112->120 m passed):
- plot 135 m (11.4 rai) with a reserve; factory 112 x 25 m, 16 bays,
82 m visitor corridor, fire wall at 90 m;
- press hall ~870 m2: two Duplex systems (EX 50 + EX 35), the Classic,
ten future Classic positions in two rows on a service trench;
- central hydraulics and compressed-air plant room (~62 m2);
- water treatment building 12 x 10 m behind galvanics: buried duct
(gravity from the +1.2 m floor), covered crossing 6 m clear;
- workshop ~200 m2 with benches, tool cabinets, 3D printers, lathe,
small CNC mill, drill, saw, welding bay, press, washer, measuring table.
Docs: galvanics (water treatment building, proposed), crane doc (workshop
fit-out; lathe and CNC mill not yet priced; corridor now 82 m),
site-candidates Payap section rewritten, README bullet.
A separate FreeCAD 26.3 model (the Mueang Chi model is untouched) sites
the plant on a 110 m square placeholder plot of Payap land, built from
BIM objects (Arch Site, Buildings and Levels, walls, slabs, columns,
beams, a ramp, Spaces with computed areas, Equipment). Every object sits
on an expression-driven base, so the Params sheet drives plot, setbacks,
floor level, building sizes, fire wall line and office gap (checked:
plot 110 to 120 m and factory 84 to 90 m, everything followed).
- Factory 84 x 25 m, production only, in process order along a 54 m
glazed corridor; press hall 465 m2 with the October fleet (two Duplex
systems, each EX 50 + EX 35, and the Classic); crane to the fire wall;
machine door and 12 m ramp at the north-west corner.
- Office building 24 x 15 m, 12 m away on its own slab with a covered
link: reception, offices, meeting/training, mastering and cutting,
listening, IT, archive. Resolves the crane-zone conflict of the old
sketch.
- Utility yard behind the press hall (boiler and chiller flagged for
re-sizing), gate, truck apron, car park, service road.
- site-candidates: new section and plot-fit note; crane doc: conflict
resolved, 54 m corridor; README bullet and layout lines; the old
sketch is labelled as Mueang Chi with the earlier fleet.
Payap also wants to work closely with the project on new student
programmes: audio engineering (mastering, lathe cutting), IT, business
administration and more.
New docs/payap-partnership.md: why it fits (mastering/cutting engineers
are the hardest hires; Payap has music, IT, business, communication arts,
an English-language International College and pharmacy labs; the plant has
a lathe, production data and a real factory application), programme areas
mapped to the docs they draw on, and what it changes: a reason to bring
the cutting room (roadmap item 27) forward, a cutting engineer before the
students, lacquer and stylus cost of teaching, pre-release security for
customer audio, student access and safety, IT work on staging only, the
link to the Payap land, BOI R&D merit. Suggested form: MOU, internships,
short certificate courses first, degree tracks later; what to settle in
writing and questions for the next meeting.
Links from README (bullet, layout), site-candidates, roadmap item 27, the
supplier map's open training item and the BOI open items.
Payap University (Chiang Mai) is interested in leasing land to the
project; a pharmaceutical facility is under construction on the same land.
New docs/site-candidates.md puts the three options side by side (Mueang
Chi lease, Northern Region Industrial Estate, Payap) with the public facts
on Payap (Mae Khao campus on the Chiang Mai-Lampang superhighway, bought
as low-lying land, ~275 acres; Faculty of Pharmacy cosmetics production
facility tendered July 2024; RPAH cannabis/herbal bioreactor centre), why
it is attractive (5 km from the old city, a university partner with music,
pharmacy and labs, production already being built there) and the checks
that could rule it out, in order: zoning for pressing, boiler and later
electroplating; whether the university can lease to a company; the GMP
neighbour's sensitivity to our emissions (argues against biomass steam
there); flooding; plot fit; galvanics consent. Questions for the next
meeting listed. Nothing re-sited: model, RFQ and site code stay on
Mueang Chi until a plot is known.
README (intro, bullet, layout), roadmap item 9 and the lease fork in
project-timeline link to it.
