Quadra Ligna

Quadra Ligna is an expert in renovating windows in architecturally valuable buildings. They renovate and glaze the original old building window, bringing them back to life. To do so, they rely on a combination of manual work and state-of-the-art technologies, such as the use of a robot to precisely cut out the window glass.

Window renovation with precision for historic buildings

An important prerequisite for precise work is the exact measurement of the windows. That is why Quadra Ligna employees measure every window on site, down to the smallest detail. Previously, this required two people, but thanks to the innovative mobile app, this can now be done by one person.

Focus on user-friendliness

The app was originally developed as a university project and is now being optimized and further developed by us. In the process, we have placed particular emphasis on user-friendliness and redesigned the user interface. In addition, we have added useful functions such as validations, automatic calculations and the automatic saving of input values. This has made the daily work of Quadra Ligna employees easier and saved a lot of time in recurring activities.

Availability of data

The availability of data in structured form is also of great importance for Quadra Ligna. The window measurement data is needed for offers, glass orders, renovations and the robot. Therefore, it is stored in the Google Cloud. Via the app, the data can be downloaded in the desired file format, which helps to improve the accuracy of the data and reduces manual processes.
