The direct answer
A reviewable takeoff connects every physical countertop piece to its drawing reference, dimensions, quantity, and fabrication details. This example tracks three pieces totaling 54.50 square feet, records two assumed cutout operations separately, and shows how stated pricing assumptions produce an estimate.

Doing Stone Takeoff's with 2cm.ai
A short demonstration focused on countertop and stone estimating.
Watch on YouTube (opens a new tab): Doing Stone Takeoff's with 2cm.ai1. Read the plan and identify unique pieces
FG-01, revision A, is an original teaching drawing created for this guide. K01, K02, and K03 are three separate rectangles. The space between the two runs is deliberate: there is no shared corner to deduct. Dimensions and locations are illustrative, not an actual customer job or an AI detection result.
Keep the piece ID with the drawing reference. For this exercise, accept the labeled dimensions as the estimating basis. On a real job, resolve drawing conflicts and missing overhang information before treating those dimensions as confirmed.
- K01: main run, 120 × 25.5 inches, quantity 1.
- K02: separate run, 96 × 25.5 inches, quantity 1.
- K03: island, 65 × 36 inches, quantity 1.
- Sink A and Sink B indicate two assumed cutout operations. Their final specifications remain to be confirmed.
2. Calculate and review the quantities
For each rectangular piece, multiply its length by its depth in inches, then divide by 144. Multiply by its quantity only after confirming that the piece is not already represented elsewhere in the takeoff.
This example uses gross surface area before subtracting openings. The two cutouts are separate fabrication operations, and no backsplash or waterfall panel is included. A shop may use a different billable-area rule; record that rule before pricing.
| Piece / reference | Dimensions × quantity | Area |
|---|---|---|
| K01 / FG-01 Rev A | 120 × 25.5 in × 1 | 21.25 sq ft |
| K02 / FG-01 Rev A | 96 × 25.5 in × 1 | 17.00 sq ft |
| K03 / FG-01 Rev A | 65 × 36 in × 1 | 16.25 sq ft |
| Reviewed example total | No cutout deductions | 54.50 sq ft / 5.06 m² |
3. Record what the drawing does not settle
The surface-area total does not establish a complete price. The teaching plan intentionally leaves production and service details open so that the handoff makes those questions visible.
| Scope item | Example handoff decision |
|---|---|
| Material | Selection, thickness, finish, slab dimensions, and direction: to confirm. |
| Finished edges | 22 linear ft is an estimate assumption, not measured from this plan. Replace it after marking charged sides and profiles. |
| Two cutouts | Operation count assumed; models, opening dimensions, and finish requirements: to confirm. |
| Seams & supports | Locations, requirements, and charges: to confirm. |
| Splash & waterfall | No quantities carried in this exercise; confirm actual job scope. |
| Services | Template and installation carry an illustrative combined charge. Delivery, tear-out, plumbing, and access are unresolved unless separately stated. |
4. Apply a stated pricing basis
To connect this takeoff to the existing estimating example, assume the shop bills 54.50 square feet before cutout deductions, adds a 12% material billing factor, and charges $68 per billable square foot. Also assume 22 linear feet of finished edge at $18, two cutouts at $150 each, and $850 for template and installation.
These are invented USD selling rates and quantities for teaching. They are not a customer quote, recommended rates, measured product performance, or 2cm.ai subscription pricing. The 12% factor does not demonstrate that these pieces fit on any particular slabs.
| Example line | Calculation | Amount |
|---|---|---|
| Material | 54.50 × 1.12 × $68 | $4,150.72 |
| Finished edge allowance | 22 linear ft × $18 | $396.00 |
| Cutouts | 2 × $150 | $300.00 |
| Template & installation | Assumed combined charge | $850.00 |
| Illustrative subtotal | Before tax and unlisted work | $5,696.72 |
5. Keep the evidence with the estimate
Save the drawing issue, piece IDs, reviewed dimensions, quantity table, and scope qualifications together. If the plan changes, identify the affected pieces and recheck edges, cutouts, seams, and services as well as area.
The 2cm.ai video on this page demonstrates the product workflow on a different example. Use it as product context, then bring a known job to evaluate drawing review, editable geometry, and shop pricing. The teaching plan above was not processed by the AI and is not evidence of its accuracy.
Common questions
Is this an actual customer takeoff?
No. It is an original teaching plan with illustrative dimensions and pricing assumptions. The embedded 2cm.ai video shows a separate product demonstration.
Can I use the 54.50 square foot total to order slabs?
Not by itself. Check piece arrangement, material direction, seam decisions, slab dimensions, defects, and usable area before determining purchased material.
Are the sink openings deducted?
No. This example reports surface area before opening deductions and records two assumed cutout operations separately. Apply the actual shop billing rule for a real estimate.
