grabowski 9d5d695855 Add parametric BIM model; rework site works, envelope and phase 2
The parametric model (docs/cnx_vinyl_parametric.FCStd) is now tracked. It
is the spreadsheet-driven Arch/BIM rebuild that supersedes the hard-coded
massing in factory_building_rough.FCStd, which is kept because the current
renders still come from it.

Site works. The two gates are consolidated into a single 10.0 m bi-parting
opening, with the wall plugged where the second one stood. The guard house
sits beside it clear of the entry corridor, and was raised out of the
ground - it had been modelled sunk half a storey. The fire water tank moved
to the north-west corner of the plot, taking utility-yard clearance from
5.6 m to 18.6 m; the fire pump house follows it. The site is now paved
continuously from the frontage through to phase 2: 4,387 m², split 1,608
heavy-duty and 2,779 general so the two can be priced apart.

Phase 1 envelope. The walls stopped flat at 8.2 m while the roof rose to
12.6 m, leaving the entire high-side wall and both gable triangles open -
about 366 m². Walls now follow the roof underside exactly. The rebuild also
starts the sandwich panel on top of the masonry dado, clearing a 31.9 m³
overlap that had been double-counting 425 m² of envelope. A vehicle ramp
(10.5 m at 1:10) and three stair flights are added, since with FFL at
+1.2 m the building had no means of access at grade.

Phase 2. Built from the design already documented in scale.md: 45 x 38 m,
two-bay sawtooth at 10.35/7.0 m with a 3.35 m glazed riser, bays falling
ESE. A three-storey office cube - canteen, office, office plus sleeping -
stands at the yard end of the west tooth, 1.65 m proud of the ridge. Its
walls and the hall walls are Arch Walls, and the yard glazing is Arch
Windows, so both carry IFC types and cut their own openings.

RFQ updated against the model throughout, with a new section on where
mineral-wool core is required instead of PIR, for compartmentation and for
acoustics.
