Core values

  • We are always DEVELOPING in the belief that to stand still is to go backwards.
  • We have a lot of scientific KNOWLEDGE and implement the latest insights in our software.
  • We are OPEN and transparent in what we do and how we do it.
  • We value EQUALITY and want our software to be accessible for every structural engineer.
  • We SHARE our knowledge with our users so that every structural engineer can take full advantage of its functionalities.



Our company is characterized by short lines of communication. All our employees have frequent contact with the users of the software.

Struct4U was founded in 2014 by Rob Baaij. Rob has more than 25 years of experience as a software engineer of structural software. This has allowed him to develop a strong vision of how structural engineering software should be put together. All insights from the past come together in Struct4U Engineering Tools.


Our development team has been assembled very carefully and currently consists of programmers, scientists, structural engineers and a mathematician. This team has developed the software over the past few years and works continuously to make the software even better and add new functionality.

The developers have decades of experience in programming calculation software and almost all have a civil engineering background. They therefore speak the language of every structural engineer.

Working method

We have a flat organisation which gives us short lines of communication with our customers. Both with large engineering firms and with independent structural engineers. Much of the functionality in Struct4U Engineering Tools was therefore developed in close consultation with our customers.

Corporate culture

Our objective is to be and remain as agile as possible and to be at the forefront of the development and ease of use of our software.

Programming technique

The Struct4U Engineering Tools are written entirely new in C#.NET. The 3D visualization engine runs on OpenGL. Many clever intelligent programming techniques have been used, resulting in unprecedented speed and minimal memory usage.


Our goal is to create modern reliable and user-friendly software for every structural engineer at an accessible price. The software is user-friendly so that it feels like an extension of yourself rather than a hindrance. The software is made so that you as a structural engineer are in control and have full insight into how calculations are made.
