General Contractors & Joint Ventures
You are responsible for the whole. We deliver the control.
Twenty subcontractors, one schedule, your liability: as a general contractor, you carry the responsibility for work that others perform. OX gives you the tools to keep it verifiably under control — from the first site walk to the last warranty deadline.

What does Open Experience do for general contractors?
With Open Experience, general contractors record defects and findings on the go, notify their subcontractors with full documentation and have every deadline tracked automatically. The subcontractors participate via free access, daily reports are created on the go — and in a dispute, a gapless, time-stamped documentation proves who reported what and when.
This is what site management without paperwork looks like
07:30 — Site walk
Photo, plan position, trade, subcontractor, deadline: the defect is recorded before you enter the next construction section.
10:00 — Regular meeting
The defect list per subcontractor is long since finished — filtered, illustrated, as a PDF. Debates about "we never received that" end here.
14:00 — Acceptance preparation
Open items per trade at a glance. The subcontractors submit their completion reports themselves — via free access.
17:00 — End of the day
The daily report is already written: recorded on the go, weather data added automatically, sent to those involved.
Your tools as a general contractor
Four building blocks cover the general contractor's day-to-day — they interlock instead of standing side by side.
- Construction Defects Construction Defects — defect notices under VOB (German construction contract procedures), automatic deadlines, free subcontractor access.
- Construction Diary Construction Diary — daily reports without after-hours work, weather data included.
- Construction Time Construction Time — deadlines and sequences in view across the project, before delay gets expensive.
- DIGIBAU 360 Every site walk fully documented — in 360°, without extra effort.
In a joint venture, everyone works in the same project
Role-based permissions instead of an isolated solution per partner: all joint-venture partners work on one shared documentation, and everyone sees what concerns them. No reconciliation by email, no second version of the truth.
What general contractors' site managers report
„Lists could be sent out immediately without post-processing, and the subcontractors found the problem spots on their own. Defect management without a specialized solution is no longer conceivable.“
- Over 100,000 defects managed in a single project
- Free access for subcontractors — defect completion reports and daily reports included
Frequently asked questions
What does my subcontractors' participation cost?
Nothing. Access for defect processing, completion reports and daily reports is free of charge — you only pay for your own users. We publish all prices openly on our pricing page (/en/preise/).
How quickly are 20 subcontractors on board?
The accounts are set up in minutes, and the interface is designed for everyday construction-site use: photo, comment, done.
What happens in a dispute over a defect notice?
Delivery, deadline, photos and processing status are documented without gaps and with time stamps — the chain of evidence you need when it matters.
Does it work on a large joint-venture construction site?
Yes: projects of any size, multiple partners, role-based permissions — from a single-family house to a large-scale project with 100,000+ defects.
And if there is no signal on the construction site?
When the connection is weak, the apps switch to offline mode automatically and synchronize later — basements and underground garages included.
