Replacing paper site checklists with an online forms system
Spennteknikk’s installers filled in technical checklists on paper and in Excel. We built an online system where project leaders prepare each form, installers complete it on site, and the system works out the numbers and produces the PDF report.

The problem
Spennteknikk’s project leaders send installers out to sites with a stack of technical forms: records, checklists and data sheets. Each job needs its own version of each form.
- Forms were filled in by hand, on paper or in Word and Excel
- Some details had to be filled in before the form went out
- Calculations and totals were worked out manually
- The first idea, an off-the-shelf form tool linked to Excel, couldn’t fill in their existing templates
Mapping the process first
Before building anything, we took a deep dive into how Spennteknikk actually works. A paid consultation and a small trial, turning one form into a PDF, came first. Then a discovery workshop where we mapped the whole process:
- Every form type, and which details are filled in before a form goes out to site
- Who prepares each form, who completes it on site, and who checks it afterwards
- Every calculation the installers were doing by hand
- Where entries need correcting after they’ve been submitted
- What the finished PDF report has to show
What we built
- Forms built from templates. Project leaders prepare each job’s forms and assign them to a named installer, who sees only their own.
- Calculations on the form. The figures installers used to work out by hand are calculated automatically.
- Smarter checklists. Pick several items at once and the totals are added up for you.
- Finished PDF reports. Every completed form produces the report, ready to file or send.
- An admin area. Project leaders manage jobs, forms and installers, and correct entries after submission.
