More than 50,000 users in seven languages work with our systems — here, eleven of them tell you what has changed on their construction sites.
Who works with Open Experience?
Open Experience is used by general contractors and joint ventures (PORR, Implenia, Leonhard Weiss), residential and project developers (Riedel Bau, Brömer & Sohn), portfolio holders such as the B&O Group, and engineering and architecture firms in site supervision (Ingenieurgesellschaft Burgert, b.i.g.). Project sizes range from around 50 residential units to large-scale projects with several thousand defects in a single platform.

What our customers say
All quotes come verbatim from our customers. Where a company wished to remain anonymous, the role is given instead of the name.
„A good relationship with subcontractors has always been very important to us. On a construction project with around 50 residential units, we used Construction Defects for the first time. After a short adjustment phase, all project managers got into the habit of recording defects, photos and freehand notes exclusively on mobile devices. Lists could be sent out immediately without any post-processing, and the subcontractors found the problem spots on their own. Defect management without a specialized solution is no longer conceivable.“
„Open Experience's Construction Defects service enabled us to handle the nearly 8,000 defects in our construction project with over 160 residential units efficiently and quickly. The quality and efficiency of my work as the person responsible for defect rectification improved dramatically after its introduction.“
„By introducing OpenExperience's services, our defect management made the leap into modern construction-site operations. Deadline tracking used to cause a lot of effort — with the Construction Defects management, the system now does everything automatically. For us as project managers and site managers, this tool has made projects of a whole new magnitude possible. The current challenges of construction supervision (service phase 8 of the German HOAI, 'Leistungsphase 8') are no longer conceivable for us without OpenExperience's services.“
„With Open Experience's software, we can document the entire construction progress from small to large projects and present it without gaps. Thanks to automatic PDF generation, defect notices can be created and sent professionally with virtually no post-processing. Deadline tracking, which used to be very laborious, is now handled automatically by Construction Defects — and the free contractor accounts are gladly used.“
„We use the Construction Defects software on a construction project with 265 apartments to record execution, acceptance and warranty defects. Processing was extremely effective and easy to handle; with conventional defect management it would not have been possible to work through the defects in that time.“
„Applied digitalization, transparency and the right use of resources matter to us. With Open Experience and its tools, we managed to get a big step closer to these goals in a very short time. What made the rollout successful for our employees, customers and subcontractors was the clear structure and simple handling of the tools.“
„Using OpenExperience's Construction Defects for many years has made our defect management clearer and more efficient, both during and after the construction task. In addition to structured recording of construction defects, the processing steps are documented transparently for all project participants. With this tool, our site management can focus more on substantive issues.“
„With this program, all construction-related topics — remaining work, additional work and defect management — can be handled transparently throughout the construction period. Using tablet and smartphone, processing is quick and easy.“
„By using Open Experience, our construction projects can be delivered more economically and with higher quality. The simplified option of digital construction documentation supports a successful project close-out and the subsequent review. Thanks to the easy handling and the good service, Open Experience was quickly integrated into our internal processes.“
„We have been working with Open Experience for quite a while now; the ease of use of this software stands out in every area. We are also delighted with the support and the speed of responses to our questions. Defect tracking has also become much simpler for our subcontractors.“
„Open Experience's services make our daily work in health and safety coordination (SiGeKo) easier. We used to create the reports in Word — maintaining those tables took a great deal of time. Today we record all events on mobile devices, add photos and plan sections, and create the report in real time right on the construction site. An absolute asset to our daily work!“

- Around 50 residential units (PORR): the first deployment — afterwards “no longer conceivable without it”
- Health-and-safety reports in real time on the construction site instead of Word tables in the office (GeoCon)
