CAISSON designs momentresisting reinforced concrete pier (caisson) foundations and evaluates embedment depths for directembedded pole foundations used in power and communication structures. 

CAISSON analyzes foundations subjected to lateral, vertical, and bending loads using ultimate strength design principles to assess soil resistance and structural capacity. 

Yes. CAISSON supports layered soil profiles and models both cohesive and noncohesive soils using soilspecific strength parameters defined by depth. 

Yes. CAISSON integrates with other Power Line Systems applications, supporting shared workflows, consistent inputs, and coordinated foundation design processes. 

CAISSON is intended for experienced foundation or structural engineers with an understanding of soil mechanics and the interpretation of geotechnical data. 

Foundation design software is specialized engineering software used to analyze, design, and verify structural foundations under applied loads and sitespecific soil conditions. It enables engineers to model subsurface behavior, evaluate stability and strength requirements, and ensure compliance with applicable design codes and standards. 

A caisson foundation, also known as a drilled shaft, is a deep foundation made by drilling a largediameter hole and filling it with reinforced concrete. It transfers structural loads to strong soil layers or bedrock below the surface. Caisson foundations are widely used for structures subjected to high vertical and lateral loads, such as transmission line structures, bridges, wind turbines, and heavy industrial facilities.
