Abstract
Task
The objective of this diploma thesis is to develop a centralized calculation tool for the architectural
firm X Architekten ZT GmbH. The application consolidates construction cost estimates, fee
calculations and fee distributions into a single unified system. The final result of these calculations
indicates how many hours an employee should spend on a given project. The results can be
exported as a PDF document whose layout conforms to the company’s corporate identity. The
solution is primarily implemented as a web application and is additionally available as a desktop
application.
Implementation
The implementation began with a requirements analysis aimed at consolidating calculations
that were previously spread across multiple Excel files into one central system. After logging
in, the application provides a dashboard for managing existing projects and creating new ones.
A structured process guides the user through three calculation steps, culminating in a final
summary with PDF export. In addition, an administrative interface enables the management of
users and system-wide calculation parameters.
Result
The application was fully developed as part of this diploma thesis and will be handed over to
the client, X Architekten ZT GmbH, upon completion of the project. Following the handover,
selected employees will be trained in a presentation, and an electronic manual will document
the application’s usage as well as the calculation workflow. Simon Brunner will remain available
for future maintenance and support. No additional costs will be incurred by the company, as
the software was developed free of charge within the scope of this thesis.
