Building assembly slip software for steel construction
In steel construction, a large share of the work happens away from the workshop. What an erection crew does on site often reaches the office as a paper slip or a WhatsApp message, and extra work becomes a dispute after the fact. Appfront builds software for erection slips in steel construction: for each day, what was erected, with which crew and equipment, what deviated, and which extra work the site manager signed off.
What is software for erection slips in steel construction?
An erection slip records what an erection crew has done on site: which marks or positions were erected, who worked and for how long, which crane or aerial work platform was on site, what did not fit according to the drawing, and what extra work was added. For a steel construction company, it is the basis for progress tracking, post-calculation, the invoice and the project file. NEN-EN 1090-2 also sets requirements for erection.
In practice, the erection slip is often a scrap of paper or a photo in a group chat. The project manager only hears at the end of the week what has been erected, extra work is agreed verbally and disputed later, and a gap in delivery or a deviation only comes to light when the crew has already moved on to another project. As a result, the post-calculation rarely matches reality.
We build custom software because every steel construction company works differently. Do you work with your own crews or with subcontractors, how do you divide projects into phases and marks, which checks do you record, and how do you invoice extra work? That determines what the slip looks like. The crew must be able to fill it in on site within a few minutes, even wearing gloves and without good reception.
Every day
One slip per crew.
From the drawing
Marks and positions.
Extra work signed off
On site.
How we build your software for erection slips in steel construction
We start with your erection process: how are projects divided up, what does a crew need to record each day, which checks are involved, and how is extra work currently agreed and invoiced. Then we build a first version of the slip with hours, marks and deviations, because that is where the biggest gain lies. One or two crews use it on real projects for a while. Signed-off extra work, equipment, progress and the integrations with your administration and planning follow once that goes well. After that, we keep the software up to date as your way of working changes.
Projects, crews, checks.
Hours, marks and deviations.
Extra work, equipment, progress.
Go-live, monitoring, and maintenance when things change.
What software for erection slips in steel construction actually does
The components below appear in almost every erection slip in steel construction. Which ones you need depends on your projects and your crews.
Daily slip
Per crew and project.
Brands
Erected according to the drawing.
Hours
Per person and phase.
Equipment
Crane, aerial work platform, tools.
Deviations
With photo and position.
Additional work
With signature.
Who we build software for erection slips in steel construction for
The software is intended for companies that erect steel and want to know what is happening on site without waiting for a pile of paper slips. The more crews and projects you have, the more it delivers.
Steel fabricators
Own workshop and erection.
Installation companies
Erection for others.
Industrial building
Industrial and commercial buildings.
Main contractors
Visibility of subcontracted erection.

This page is about erection on site. For the whole steel construction company, see our page on steel structure software, for the workshop our page on the FPC file and EN 1090, and for slips in other sectors our page on the service engineer slip app. You can read about our approach at building software.
Why Appfront for your software for erection slips in steel construction?
Extra work that was never recorded, a final costing that doesn't add up, or a deviation that only surfaces weeks later costs a steel construction company margin and leads to disputes. That is what we build on: a daily report for every day, marks taken straight from the drawing, deviations with a photo and extra work with a signature.
Extra work on record
Signed, not debated.
Progress known
Same day at the office.
Final costing adds up
Hours per phase and project.
Security and privacy in software for assembly reports in steel construction
The software processes data on employees, subcontractors and projects: hours, names and sometimes locations. We only use what the report needs, access is set up per role, and a subcontractor only sees their own reports. Every report and change is logged with a name and timestamp.
The software runs in a European data centre, with encrypted storage and daily backups. Signed reports are retained, so if there is a dispute about extra work you can show what was agreed.
Frequently asked questions about software for assembly reports in steel construction
Questions that steel construction companies ask before they get started.
A record of what an assembly crew did on site in a day: which marks or positions were erected, who worked and for how long, what equipment was on site, what deviated and what extra work came up. It is the basis for progress tracking, final costing, invoicing and the project file.
Yes. If your drawing package or model can export a list of marks and positions per phase, we put that on the report. The crew ticks off what has been erected instead of copying it out. We look at which route fits in the first step.
Yes. The app works offline and sends the report as soon as there is a connection again. Photos and signatures are kept until they have been safely transferred.
The foreman records the extra work with a description, photos and the hours or materials, and the client's site manager signs on the tablet. The signed report goes straight to the office, so there is no later dispute about what was agreed.
Yes. A subcontractor gets access to the daily reports for their own crews and projects, and sees nothing from other parties. That way, even with hired-in erection crews, you have the same data in the same format.
A deviation, such as a part that doesn't fit or a missing delivery, is recorded with a photo and position and goes straight to the project manager. They can follow it up with the workshop or the client while the crew is still on site.
For steel construction and erection companies with multiple crews and projects that want to better capture extra work, progress and post-calculation. If you have one crew and a handful of straightforward projects, a simple report in an off-the-shelf app may be enough.
