PROJECT 10 / TCE4047

An estimated top and a separate strip

The upper top is a visual draft. The lower notched Y9006 strip belongs to a separate job.

DRAWING CHECK · 29 OCTOBER 2026

1 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

  • Lower independent Y9006 strip is 18.625 × 5 with 1 × 1 corner notch; 92.125 square inches, 0.059435365 m2 gross polygon.
  • Upper source explicitly shows 22.5 depth, 11.75 step, 36.5 sink-center-to-right dimension and 3 cm thickness; full length absent.

Needs confirmation

  • 68-inch full length and 24.5-inch step location are invented visual assumptions, clearly labeled; never treat as measured job data.
  • Upper 9.25 local dimension and sink location need clarification.
  • Upper TCE4047 and lower Y9006 are different jobs/materials and must never be merged.
  • Support review covers only the lower calculated strip and explicitly holds upper capacity checks.

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

PROJECT 10 / THREE-DIMENSIONAL PREVIEW

Three-dimensional preview of Upper stepped sink countertop

Drag to orbit after opening the 3D model. Use + / − to zoom.

Visual scenario: 68 in overall length and 24.5 in step offset are estimates chosen for the model, not measured job dimensions. Sheet notes include 22.5 in depth, 11.75 in step and 30 mm thickness; the 9.25 in local note remains unresolved. No area or mass is assigned to this estimate. Surface finish is illustrative.

This is the missing upper countertop. The 68-inch length and 24½-inch step offset make a visual draft; they have not been measured. The local 9¼-inch note and sink position need clarification. Area, mass and weight remain unassigned. The lower Y9006 strip remains a separate material group.

Sink and backsplash notes

Nominal sink template: 17¾ × 11¾ in, radius reading 1 in; actual cutout and position unconfirmed. Backsplash note: 3¼ in high, full length unconfirmed. Neither becomes an additional stone part.

Thickness and density used in this table
  • Separate lower job: notched Y9006 strip: 20 mm drawing reading; density unassigned in this fixed record.

Per-piece gross estimates. Sink and fixture openings are not deducted. Blank results need missing inputs; support examples may use separate, labeled assumptions.

Lower drawing: a Y9006 strip at 20 mm thickness, recorded as its own material group. The upper TCE4047 drawing has an incomplete outline.

Measurements & calculation steps

Separate lower job: notched Y9006 strip

length: 18.625 in · height: 5 in · upper Right Notch Width: 1 in · upper Right Notch Depth: 1 in

A = 92.125 in² (rectangle addition) × 0.0254² = 0.0594 m²
V = A × 0.02 = 0.00119 m³
Mass and weight need the missing inputs listed above; a blank is not zero.

Separate physical job below divider; material Y9006 and 2 cm explicitly written. Included in all-visible inventory under its own material, not merged with upper TCE4047 job. Corner 1 x 1 notch is an outer-profile subtraction.

The 1 × 1 in edge notch is already removed from this outside polygon; do not subtract it twice.

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.
