✓  Design, analyse and detail foundations with S-FOUNDATION, the most customisable and automated foundation software.

​✓  S-FOUNDATION automatically generates and manages the underlying structural FEA model as you create the foundations.  

✓  Analyze with a linear or non-linear analysis, followed by a design-code assessment to produce detailed engineering reports.

✓  Customize and automate any part of the process while maintaining  complete control over geometry, material, reinforcing, and loading.

Foundation Modeling

✓  Model Virtually any Foundation

S-FOUNDATION will model virtually any foundation including isolated footings, combined footings, continuous footings, wall footings, strap footings, and mat foundations.

Foundations can include pedestals, walls, piles, steps, holes, and areas of increased or decreased thickness.

✓   Quick and Easy Footing Creation

Easy to use graphical tools help users define a footing component database to efficiently model footings.

S-FOUNDATION modelling tools are designed for efficiency with standardised keyboard shortcuts found in other S-FRAME and 3rd party software to help users become productive quickly.

✓   Model Mat Foundations of any Shape and Size

No matter what shape and size your architectural drawings specify, virtually any mat foundation can be modelled quickly and easily with the S-FOUNDATION software.

⭐️     Automatic Finite Element Model Generation

The underlying finite element mesh is automatically and quickly generated using the same industry-leading mesh algorithms used in S-FRAME.

Mesh constraints are fully adjustable by the user. Update your model and watch the algorithms redefine a new mesh using your constraints.

S-FOUNDATION Import and Export

Full S-FRAME Import and Export Integration

Import the superstructure model from S-FRAME and use the model as a guide to easily model your footings and foundations. Base reaction loads from the superstructure analysis are automatically applied to the foundation model. After completing the foundation model, analysis, and design, transfer the model back into S-FRAME for further analysis. The imported foundations will provide more accurate and realistic support conditions for the superstructure.

Full S-FRAME Import and Export Integration

Run S-FOUNDATION as a stand-alone analysis and design foundation application or integrated within S-FRAME Analysis. With S-FRAME Analysis, two-way data transfer automatically applies foundation loading conditions and post-processing from S-FRAME Analysis, then combines the optimised foundation model with the S-FRAME Superstructure model for a more detailed soil-structure interaction analysis.

Alternatively, import geometry and loading data using CSV files to use as the starting point for your model.  Import support data (locations, reactions, preliminary foundation design) from 3rd party analysis software, create the model, and optimise the foundations.


Soil Supports

Nonlinear zero tension soil springs automatically generated on foundation joints considering the assigned soil properties. View and verify spring stiffness, pile head fixities, and tip support conditions to match desired analysis parameters.

Soil Pressure and Uplift Analysis

Visualize soil pressure contours to identify areas of uplift and run an uplift code check.

Rigid Zones

Rigid zones automatically created under pedestal footprints and walls using rigid links, to avoid load concentration and ensure loading pressure is transferred to the pad realistically.

Strip Lines

S-FOUNDATION automatically generates strip integration lines, with exclusion areas, based on code requirements and pedestal locations.

Automation and Customization

Customisable Design Wizards

S-FOUNDATION includes design wizards to help design foundations 

according to your custom constraints. Wizards use the S-FRAME OpenAPI, 

are open source and fully customisable to meet your design requirements.

Customisable Modelling Wizards

Included modelling wizards in the foundation software provide a starting point for

modelling your standalone model and allow further customisation to meet user needs.
