Pile Takeoff & Materials Estimator

▾ Symbol classes (pile types)

Workflow: draw the Manual map area, choose a pile type, use Teach symbol to box one clean example, then click Find matching marks. Add more examples only when the same pile type is drawn in different styles.

Estimator tip: keep the green map box around the pile plan only. Use Exclude for schedules, legends, title blocks, and detail views so examples do not inflate counts. Enter each mark's Schedule qty to reconcile against the drawings.

▾ Manual map area

No map area set. Counts can include schedules or details until you draw one.

X / Y

Width / Height

Fallback when auto area selection is wrong: click Drag map area, then draw a green box around the actual pile plan. Exclude schedules, legends, title blocks, and details separately with Exclude.

▾ Detection settings

Match sensitivity

0.66

Missing symbols? drag LEFT (looser). Marking junk? drag RIGHT (stricter). Re-Detect after each change.

Match rotations

also find symbols turned 90/180/270° (slower)

Min spacing (px)

0 = auto. Increase if two marks land on one symbol; decrease if piles sit very close together.

Number marks

show a number on every mark so each one can be eye-checked

Review candidates

show amber near-miss candidates on the drawing

Auto-set scans every sensitivity and parks the slider where the count is most stable. Amber ? marks are near-misses just below your setting: click them in Add mode to keep, Erase mode to reject, or resolve all at once.

▾ Image cleanup (faint scans / lines)

Plan too light, or gridlines/columns hard to see? Clean it up here. This also improves symbol detection.

Preview cleaned

white lines on black background

Adaptive is best for faded blueprints with uneven lighting; Otsu makes crisp black/white. Detection uses the cleaned image whether or not Preview is on.

▾ Estimator QA

Use this before export: plan area reviewed, schedules/legends/details excluded, amber marks resolved, schedule quantities reconciled, and assumptions written down.

Assumptions / notes

▾ Design check (per pile, from load + soil)

Uses the selected class's pile type. Preliminary sizing aid based on published methods (torque-to-capacity; individual-bearing). Confirm with your engineer & geotech report.

Service load (kips)

Factor of safety

Soil at bearing

SPT N (blows/ft)

Su undrained (psf)

Eff. unit wt γ' (pcf)

Machine max torque (ft·lb)

▾ Bill of materials & cost

Item	Qty	Unit	Unit $	Total $
Project total				$0

Quantities come from your counts × each class's parameters. Edit unit prices to price the job.

▾ Estimate summary (install + totals)

Production (piles/day)

Crew cost / day ($)

Mobilization ($)

Load tests (#)

Load test each ($)

Spoil disposal ($/cy)

Contingency (%)

Labor = crew-days x crew/day (production rate sets days). Materials pull from the Bill of materials prices. Load-test and mobilization are standard deep-foundation bid lines. Tune to your rates.
