More Information

Enrich photos with information

The photos are available to you in real time in the 123-Office. There you can review the images, enrich them with information and post-process them simply in the photo documentation.


Record special services, remarks & notes

The photo documentation app logs the time and GPS coordinates of each capture. In addition, you and your co-workers can note special services, comments, notes, and notations. The notes remain stored in your site documentation at all times.


Use photo documentation automatically for your construction diary

As a project manager, you can simply place a check mark next to captured photos, which will be used directly for your construction diary, as well as add a comment if you wish. To do this, you have to have the projects module with the construction diary active in 123onsite.
