DRAWING CHECK · 29 OCTOBER 2026

3 retained component records. These tables cover selected readable outlines, not the whole job. Mass and weight are gross estimates before sink and fixture deductions.

What was checked and what is still missing

Compared with the paper

  • Three raised left panels retain separate row labels 19/20/21.
  • Row19 width 45.5 + 30.125 + 29.375 = 105; row20 28.75 + 30.25 + 46 = 105; row21 46.125 + 30.25 + 28.75 = 105.125 checked.
  • Center heights 33.875, 32.625, 32.375 and base heights 19.75, 20, 19.75 agree with retained readings.

Needs confirmation

  • Corresponding right-side notched wall panels and cropped upper row are not fully resolved.
  • Electrical openings have local callouts but need exact size/position confirmation.
  • TCE1220 2400 kg/m3 is a labeled family estimate.

The source images were visually reviewed; handwriting and field dimensions are not independently verified. Actual support positions and connection capacities are also unconfirmed.

THE PROJECT AT A GLANCE

Assembly sketches join only faces supported by the drawing. Other pieces are grouped as sets. These are reconstructed schematics, not AutoCAD exports.

WHY THE CALCULATIONS MATTER

Understand the material before planning the job.

Area and thickness determine stone volume. Density turns that into an estimated mass, and gravity gives its weight. These quantities support planning and discussion with the family business; supports, handling and installation need fabricator or qualified professional review.

Area → volume

A = L × D, or add rectangle areas
V = A × t
1 in = 0.0254 m

Table results are per component; quantity is shown separately. Sink and fitting templates remain notes until confirmed. Grouping does not combine different rooms or alternative sheet versions into one slab.

Volume → mass → weight

m = ρV
Fg = mg
g = 9.81 m/s²

Mass uses kilograms and weight uses newtons. A blank result means thickness or density is unconfirmed. Density assumptions and provisional readings remain identified in the calculation notes.
