About LARSA, Inc.

LARSA, Inc. develops advanced software for the analysis and design of bridges and structures based on the finite element method. Our flagship product, LARSA 4D BRIDGE Series, is recognized as the premier software for bridge engineers with the innovative tools necessary to support the life of a bridge project from design to construction.

By coupling structural analysis and design with the latest computing technology, LARSA 4D has become the most reliable software of its kind for segmental, cable-stayed, suspension, steel girder and other bridge forms, as well as other structures requiring geometric or material nonlinearity, complex three-dimensional geometry, or advanced staged construction analysis.

LARSA, Inc. is privately owned and based in New York, with all its software development and product supports services conducted in-house.
