SCAD Office 23.1.1.1

SCAD Office is a comprehensive structural engineering software suite developed by SCAD Soft, a Russian company specializing in finite element analysis (FEA) and design tools for civil and structural engineers. It is widely used for the analysis, design, and verification of buildings, bridges, industrial structures, and foundations, adhering to international and Russian standards such as SNiP (now SP), Eurocodes, and GOST norms. The software is certified for compliance with GOST R ISO/IEC 9126-93, GOST 28195-89, GOST R ISO 9127-94, and RD 50-34.698-90, with Gosstroy of Russia certification for SNiP compliance.

Version 23.1.1.1, released around late 2022 to early 2023 (build dated November 22, 2022), is part of the 23.x series and focuses on enhanced performance for 64-bit systems, improved user interface, and expanded automation for complex structures. It builds on version 21.1 (from 2021) by introducing better integration with BIM workflows, advanced stability modules, and refined reinforcement design tools. As of October 22, 2025, a minor update to 23.1.1.3 is available, but 23.1.1.1 remains a stable release for many users.

The suite is designed by engineers for engineers, offering a unified graphical environment for modeling from simple frames to intricate 3D assemblies, with seamless transitions between analysis, design, and reporting.
