“
ProtaStructure Suite is indispensable for my work as an independent engineer, especially with reinforced concrete (RC) building projects. Several key features have significantly enhanced my workflow.
“
A few years ago, I noticed that my engineers needed to learn a range of different software in order to model and design a single project, especially when considering Reinforced Concrete and Foundation Design. This wasn't particularly productive and meant that I had to support a range of different software applications.
“
Prota Engineering's engineering and BIM teams used ProtaStructure throughout the entire Istanbul New Airport Terminal Building design phases in order to produce fast and safe models which also minimizes human errors.
“
My journey with Prota Software began through a recommendation from a long-time colleague, Duško Dimitrijevic. After exploring the capabilities of ProtaStructure Suite, I was impressed with what it had to offer. Testing the software quickly revealed that it could meet all my needs, especially in terms of ease of modeling and output results, which are critical for our main product.
“
ProtaStructure Suite has noticeably enhanced both the speed and accuracy of our structural design workflow. Its integrated 3D modeling and parametric reinforcement tools allow us to deliver more coherent, precise, and well-coordinated projects, ultimately improving our overall engineering efficiency.
“
ProtaStructure Suite has greatly enhanced my professional capabilities with its flexibility in modeling, calculations, and detailed checks. It empowers me to push the boundaries of structural design and confidently tackle complex, innovative projects. Thanks to ProtaStructure, I'm setting new standards in structural engineering, and I highly recommend it to professionals seeking excellence.
