Steel BOM · weld & fit-up hours · coating area · should-cost
Feed FabDFM the steel BOM your detailing software already exports, or a 3D model, and get back a should-cost estimate for the whole weldment — cut, drilled, fit, welded, blasted, coated, delivered — plus a routing traveler the shop can work from. Price a job in the time it takes to open the file, not the afternoon it takes to build a takeoff by hand.

The problem
Tonnage, connection hours, weld metres, coating area — added up by hand, and every estimator does it a little differently. Slow, inconsistent quotes lose jobs to the shop that answered first.
Fit-up and welding hours are what actually set the cost on a weldment, not the steel itself — and most quotes are still built on an estimator's gut feel for how many hours it'll take.
Sanity-check a supplier's steel price, or re-price a revision, and you're back at the beginning — pulling the BOM apart and re-adding it by hand.
What you get
Feed Partimation the same BOM your detailing software already produces — no re-modeling the job in a separate costing tool, no re-typing member lists into a spreadsheet.
The four numbers that actually set a weldment's cost come straight out of the takeoff, not an estimator's gut feel — so two estimators land on the same price.
See the price at every quantity, with the tonnage price breaks that apply at real mill order sizes — not a flat per-piece number that ignores how steel actually gets bought.
Weld metres and connection types come off the member contacts automatically, with hand-weld markup applied — then it all ships as a routing traveler carrying BS EN 1090 execution-class context (advisory, not a certification).
How it works
Upload the steel BOM your detailing software exports, or a 3D model. No re-modeling, no template.
Tonnage, fit-up hours, weld metres, and coating area come out of the takeoff automatically, each with the number behind it.
See the price at every quantity, tonnage price breaks included, so you know exactly where the next mill order gets cheaper.
Get a shop-floor traveler with the routing and EN 1090 execution-class context already on it — ready for the floor, not just the quote.
Pricing
Priced for a one-person job shop and a production fabricator alike. Takeoff and should-costing are unmetered — run as many BOMs as you like.
EUR prices exclude VAT, added at checkout where it applies. Early adopters keep their price as the suite grows.
Run it your way
Sign in and price a weldment from any browser. We run the compute, ship the updates, and keep your data yours — the shared model only ever learns from your own jobs to calibrate your rates.
Defense, infrastructure, and anyone under NDA can run the whole thing on their own hardware. Licenses and updates are signed files — it never phones home, so an air-gapped install stays air-gapped.
Go deeper — welding
If fit-up hours and weld cost are the number you don't trust, WeldDFM is the same FabDFM engine, focused on the joint — bolted vs. welded calls, deposition time and consumables by process, and EN 1090 execution-class context, one joint at a time.
