Why does European construction need European software?
Because the documentation is the product. A German Bautagebuch is a legal document with expectations about what it records and when. A French OPR produces réserves in a form the maître d’ouvrage signs off. Handover packs, retention periods and defect liability all follow national contract law.
A platform built around American project conventions produces output that has to be reformatted by hand, which removes the point of digitising and leaves the practice awkwardly half-digital — harder to defend in a dispute than consistent paper would have been.
The archive matters too. Construction documentation is evidence years after handover, so knowing whose law governs it and being able to export it in full is worth more than it appears while the project is running.
What makes site software get used?
Offline capability, without exception. Half a building under construction has no signal, and a tool that cannot record a defect without a connection is replaced by a phone camera within a week.
Subcontractor licensing second. If closing a defect requires the subcontractor to buy a seat, they will not, and the process reverts to email with somebody retyping. PlanRadar and CAPMO both price that access separately for this reason.
And the number of taps. Recording an observation should be tap the drawing, photograph, choose a trade, assign. Anything requiring a form filled in on scaffolding gets done later from memory, which is how site diaries become fiction.
Which stage are you actually buying for?
Four different jobs sit under one heading. Tendering, where the money is decided — Cosuno. Site execution: diaries, defects, observations — PlanRadar, CAPMO, BulldozAIR. Progress and valuation — Sablono. And the common data environment across organisations — Thinkproject.
Most companies start with site execution because the pain is daily and visible, then discover the tendering and progress gaps afterwards. Buying a site tool to solve a tendering problem is the most common mismatch in the category.
