Web App design in archaeology

C'est ce que AnalyticBase Sàrl recherchait dans leur web design

We need a professional design for a web app. Only the main page for now. Users will work on this app all day long so we need it to be looking clean and have calm colors and nice filling and professional look. This app will be used as well on tablets. We already have a base design (attached here) but need it to be improved or redone. This app is used in archaeology, to input data of their discoveries.
There are 2 different lines of tabs. It's described in the second print screen attached.
If we are satisfied, there will be more pages to design for this app in the same direction after this project is closed. Voir plus
