The LARSA 4D Difference

At LARSA, we've spent the last three decades leading the field of bridge engineering software with the latest computing technologies produced to the highest standards of quality. During this time we've developed a way of doing things that we call The LARSA 4D Difference.

It's about an unwavering commitment to all steps that go into the development of our software, and the ever-changing needs of the bridge engineering community supported by LARSA's staff of engineers and researchers that are highly specialized, yet very collaborative. But most of all it's about our commitment to deliver the highest degree of customer satisfaction to our clients, who believe there's a better way of doing things.

LARSA 4D Version 2023.R1

LARSA 4D 2023.R1 is the first major release in 2023. The version includes numerous improvements throughout LARSA 4D and LARSA 4D’s new Inter-Suite and C-Suite product additions supporting interoperability and integrated design for concrete components. Visit LARSA 4D's product download page for more information.

2023 New Product Additions

LARSA 4D C-Suite

LARSA 4D C-Suite is a design expansion for LARSA 4D BRIDGE SERIES integrating analysis and design capabilities for concrete components. Rapidly perform Biaxial Interaction Analysis, Moment Curvature Analysis, and detailed code checks for reinforced and pre- and post-tensioned concrete structures, including pier columns.

LARSA 4D AOM Pile Foundation Modeler

The LARSA 4D AOM Pile Foundation Modeler is a tool for the modeling and analysis of pile foundations based on the principles of soil structure interaction. The tool uses parametric input to rapidly generate analytical models of one or more pile foundations that can be analyzed directly within the Modeler or exported to LARSA 4D.
