Pile Takeoff & Materials Estimator

▾ Symbol classes (pile types)

Workflow: select the takeoff area, choose the symbol shape and pile type, then click Run pile count. Use Teach symbol only as a fallback when the sheet uses an unusual pile mark.

Estimator tip: keep the green takeoff 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 count to reconcile against the drawings.

▾ When to use manual controls

Takeoff area

Use on every real sheet before final count. Box only the actual pile plan so schedules, title blocks, and detail views stay out of the count.

Exclude

Use when the plan box must include notes, keys, callouts, or details. Red boxes are ignored by counts.

Teach symbol

Fallback for unusual marks. Box one clean mark, not a label, leader line, dimension, or schedule symbol.

Sensitivity

Lower when real piles are missing. Raise when dimensions, text, or grid marks are being counted as piles.

Review marks

Turn on when Run pile count reports candidates. Keep real missed piles, dismiss junk, then export only after review is clean.

Clear / Reset

Clear marks when the scan is wrong but the taught example is good. Reset symbol when the example itself was bad.

Count factor

Use when the pile schedule says one drawn pad or mark represents 2 or more piles.

Schedule count

Enter the schedule count to catch mistakes before pricing or sending the takeoff.

▾ Select takeoff area

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

X / Y

Width / Height

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 near-matches that are not counted yet

Auto-set scans every sensitivity and parks the slider where the count is most stable. If the schedule count is higher than the reviewed count, Review schedule gap turns on amber candidates and Add mode so you can click only the true missed pile.

▾ Review + learn log

Browser-local feedback data. It records what the app found, what was reviewed, and what a person corrected so future symbol libraries can be trained from real estimator decisions.

Logs auto-found, possible, accepted, rejected, manual-added, manual-erased, clear, undo, and redo actions. The plan image stays local; exported events include coordinates and settings, not image crops.

▾ Image cleanup (faint scans / lines)

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

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.

▾ 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.

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.
