The digital companion on your construction site

We attach great importance to a flexible, easy-to-use and reliable solution. 

Therefore, with our professional construction software, you benefit from complete documentation via construction site diary and ensure consistent transparency throughout the company. This ensures an uncomplicated flow of information and rapid communication within your team and thus bundles all important documents and plans in one central location. With just a few clicks, the work carried out on the construction site, as well as the people working and the machines used, can be listed comprehensively via the construction app.

In addition, thanks to the complete recording of important data, you also create the necessary legal certainty, which is particularly relevant in the construction industry. Thanks to our construction site app, you not only document your construction work faster and much easier, but also additional agreements, changes, photo logs and much more can be recorded completely and processed transparently for the entire team. It is also possible to capture the client and customer signatures directly via the app.

Construction times and progress always in view

The extensive time recording of our construction software enables your employees on site to document their working hours and progress immediately and easily via app. 

The direct input via smartphone or tablet eliminates the effortless and manual rework on the PC.

Thanks to the simple "Start/Stop" function, the mobile time clock also ensures that working times are recorded to the minute. As a result, all internal employees are also well informed about the current status of the construction site and project progress can be optimally monitored. Potential delays or problems can thus be identified in good time.

In addition, thanks to simple documentation of the material used, it is also very easy to determine when and where further materials are required and can therefore be requested in good time. Our app automatically creates the necessary delivery notes.

An intelligent tool for the entire construction process

Whether construction planning, documentation of the construction site progress via construction site diary, feedback on structural changes, photo documentation or the recording of material consumption and working times - 1Tool bundles all the necessary functions for your construction site management in one piece of software.
