If Your Team Does It on a Computer, AI Can Do It: What to Automate Around Tekla PowerFab

If you run a steel fab shop on Tekla PowerFab, you already own a capable system. But PowerFab can’t read the packing slips, mill certs, supplier quotes, invoices and PDF drawings that land in your office every day. Somebody still keys those into PowerFab by hand, then turns PowerFab data back into reports, emails and spreadsheets.

That’s the work AI can take on. The simple rule: if someone in your office does it on a computer, AI can do it. It reads, types, clicks, compares and writes the way your people do, and your people approve the result. It also never gets bored on the fortieth heat number of the day.

Here’s what that looks like, workflow by workflow, for owners who have PowerFab but don’t live in it.

Why do PowerFab shops still retype so much?

In one LinkedIn discussion among PowerFab estimators, people described building takeoffs in Excel, importing them, then moving numbers back into Excel to price the job. One warned that typos get kicked out on import, and too few people check the import log.

A Trimble case study tells a revealing story. Before PowerFab, All Things Metal was tracking status in spreadsheets and coordinating by email, with too much time spent managing data instead of fabricating steel. PowerFab fixed a lot of that. But even now, with PowerFab working well, their next step is connecting it to their accounting system to stop entering the same data twice. That gap between systems is where AI fits.

PowerFab has the features. The hard part is the gaps: getting messy information in, clear answers out, and the same numbers into your other systems without retyping them.

How does AI work alongside PowerFab?

• PowerFab stays the system of record. Your jobs, POs, inventory and costs stay put. Everything here adds to PowerFab.
• It uses a computer like your team does. The AI logs into PowerFab under its own user account and works through the same screens. It also works across your email, Excel, Bluebeam, supplier portals and accounting software, so it can handle a whole workflow, not just one step.
• It uses the shortcuts you already have. PowerFab has an open API and Excel imports for estimating, purchasing, inventory, production control and time tracking. Many shops barely touch them. We set them up as part of the work.

No big IT project, and no new system for your team to learn.

What can you automate around PowerFab, workflow by workflow?

1. Receiving, heat numbers and mill certs

Today: Your receiver matches the packing slip to the PO, types each heat number into PowerFab, files the mill cert and chases the ones that never arrived.

With AI: The receiver snaps a photo of the packing slip. The AI matches each line to open PO items, pulls heat numbers from emailed certs, checks chemistry and mechanical properties against the grade ordered, and drafts a request for any missing cert. The receiver approves the receipt before it’s saved, and your QA lead still signs off on cert acceptance.

2. Dashboards and weekly status reports

Today: Your PM runs several reports to answer a GC’s “where’s my steel?”

With AI: A morning digest lands in your inbox: backlog, late POs, drawings out for approval, upcoming loads and jobs over on hours. Each GC gets a draft weekly status for the PM to review and send. You can ask plain questions, like “which jobs are over budget on labour?” Reporting is read-only, so it doesn’t change your data.

3. Supplier quotes, from request to PO

Today: Quotes come back as PDFs, emails and suppliers’ own spreadsheets, priced per hundredweight, per foot or per pound. Someone lines them up by hand.

With AI: With your approval, the AI sends the requests, follows up on the slow ones, converts units and lays out a side-by-side comparison with lead times. Your purchaser picks the supplier, and the AI prepares the PO for the purchaser to approve before it’s saved in PowerFab.

4. Drawing revisions and change orders

Today: A new revision arrives and someone compares it to the last set by eye.

With AI: The AI lists every added, deleted or changed piece with the tonnage impact, and checks PowerFab for pieces already cut or welded, so you catch costly changes early. It builds the change-order backup and a draft email to the GC for your PM to price and approve.

5. Supplier invoices

Today: Someone checks each invoice against the PO and what was received, then keys it into accounting.

With AI: The AI checks each invoice line by line against the PO and the receipts in PowerFab, and flags mismatches with a draft dispute email. Once your bookkeeper approves, the AI enters the invoice in your accounting software.

6. AI takeoff into PowerFab estimating

Today: Your estimator keys shapes, sizes, lengths and grades off PDF drawings. In a busy bid week, some jobs never get bid.

With AI: The AI builds a draft takeoff, matches shape names to PowerFab’s material list, and flags anything PowerFab would reject, like a section size that doesn’t exist. Your estimator starts from a draft instead of a blank sheet, so you can bid more jobs with the same team.

To be straight about it: 2D takeoff accuracy varies from one drawing set to the next. Your estimator reviews the draft, adds labour, connections and judgment, and owns the number.

And the rest of the office

• Bid invites: summarizes scope, exclusions and due dates, tracks addenda and keeps your bid log current.
• RFIs and submittals: drafts RFIs and reminders, and tracks every open item and drawing out for approval.
• Shop floor status: a fitter says “14B is welded” into a phone, confirms it, and PowerFab stays current.
• Shipping: drafts load lists, bills of lading and delivery notices from PowerFab.
• Time and job costing: prepares hours against the right jobs for a supervisor to approve, and flags jobs where labour is running over.
• QA and closeout: turns inspection photos into reports and NCRs, and assembles closeout packages.
• Progress billing: drafts each billing, including holdback, from what’s been fabricated and shipped.

How do you keep AI safe inside PowerFab?

AI is good at reading and preparing. It shouldn’t make the final call on your data. Our rules:

• Nothing is saved without approval. The AI prepares; your people approve receipts, POs, estimate lines, change orders, invoices, and emails to GCs and suppliers.
• PowerFab’s own doors only. Screens, imports and API, never around them.
• Its own user account. Your admin controls its PowerFab permissions, just like a new hire.
• No direct database writes. Ever. PowerFab’s own checks for inventory, costing and history still apply.
• Every action is logged. You can see exactly what the AI did and when.

The AI runs on a computer in your network or a secure machine you approve. What’s possible depends on your PowerFab version and setup, so we check that first.

What changes for your team, and what stays the same?

What changes: less typing, hunting and chasing. Your receiver approves receipts instead of keying them, and your PMs send reports instead of assembling them.

What stays the same: PowerFab, your screens and your processes. Your estimator owns the estimate, your PMs own the GC relationship, and QA signs off on mill certs.

Say that second part out loud to your team. This takes work off their plate; it doesn’t second-guess their judgment.

How do you get started?

1. Pick one workflow that eats the most hours or causes the most errors. Receiving and reporting are often easy first wins.
2. Map it with the people who do it, including the spreadsheets and workarounds nobody admits to.
3. Run it alongside your current process for a few weeks. When your team trusts the results, they approve instead of redo.
4. Add the next one. It goes faster because the groundwork is done.

Frequently asked questions

Do we have to replace Tekla PowerFab to use AI?

No. The AI adds to PowerFab. Your jobs, POs, inventory and costs stay in PowerFab, and the AI works through PowerFab's own screens, Excel imports and API. Nobody on your team learns a new system.

Will the AI change our PowerFab data without anyone checking?

No. Nothing is saved without approval: a person on your team approves every receipt, PO, estimate line and change order before it goes into PowerFab. The AI uses its own login that your admin controls, never writes directly to the database, and logs every action.

Which PowerFab workflow should we automate first?

The one that eats the most hours or causes the most errors. Receiving with mill certs and weekly reporting are often easy first wins, and reporting is read-only, so it carries the least risk. Run it alongside your current process for a few weeks first.

Can AI do our steel takeoffs?

It can build a draft takeoff from PDF drawings, matched to PowerFab's material list, so your estimator starts from a draft instead of a blank sheet. Accuracy varies by drawing set, so your estimator still reviews it, adds labour and judgment, and owns the number.
