Switching between different software programs to complete a project can be time-consuming and frustrating, especially when trying to meet multiple deadlines and client requirements. ProtaStructure Suite allows me to complete all stages of a project, from modeling to detailing, in one place. This was a huge advantage, so I became a licensed user immediately.
Víctor Bisonó Ramia
Gerente General en Grupo Inercia SRL
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.
Nebojša Savićević
Direktor at INTERPROJEKT
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.
Perunding RekaCekap
Structural Engineering Consultancy
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.
Danyal Kubin
Chairman & Founder
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.
