Weld takeoff from piping ISOs

What it counts

• Butt welds (BW), socket welds (SW), and olet welds, each by nominal pipe size.
• Shop welds and field welds in separate columns. Field welds are picked up from the FW callouts on the drawing.
• Field fit welds (FFW) on butt and socket welds. Each one adds 6 inches of pipe to the materials export for the trim.
• Pipe supports from the BOM, in the same sheet as the welds.

How it finds the welds

TakeOffTrak reads the drawing itself, not a picture of it. It finds the weld symbols in the PDF's linework, picks up the FW and FFW callouts, and then sorts each weld into butt, socket, or olet. It reads the weld symbol styles of many drawing formats.

Scanned or image-only ISOs have no linework to read. On those, TakeOffTrak still reads the BOM, and you place the welds by hand with the weld tool. The app tells you when a drawing is image-only, so it never looks like a drawing with zero welds.

You check it, you own it

Turn the overlay on and scan the drawing. A weld with no marker stands out. Then fix it:

• Add a weld with one click where it is missing.
• Delete a marker that is not a weld.
• Lasso a group of welds and change their type or section in one move.
• Mark a field weld as a field fit weld.
• Undo and redo anything.

The export always matches what you see on the drawing. If you changed it, the count changed.

What lands in Excel

The Weld Takeoff export has one row per drawing per pipe size. Each row carries the spec, material, and schedule, then the shop weld counts and field weld counts by type, the shop support count, and a total. You can export shop welds, field welds, or both.

Every count carries its size, so diameter inches are one column of math: weld count times NPS. Your labor units stay yours.
