Transform how you design deep excavations, tunneling, and flood control embankment works!

BRaced excavation with steel struts

Every year we work hard to make a great solution better. Our upcoming DeepEX 2023 is coming with new features to better help you deliver the right solution. After many years of requests, we have implemented MSE walls, stone columns, and geo-reinforcements. We have also expanded the ability to import large scale city data from publicly available sources and new elevation generation tools. The new version comes with corrugated sheeting and tunnel options and new analysis methods, improvements in slope stability slicing, and speed enhancements in large scale visualizations.

Text to model features

Write descriptive commands and automatically generate excavation models.

Internal steel bracing design for deep excavations

New Structural Codes:

Concrete: AREMA-15, Indian IS 456:2000, Canadian CSA A23.2.19, Hong-Kong

Steel: Indian IS800:2007, Canadian CSA S16-19, Hong-Kong HK 2021


New Load Combinations:

Canadian NR24-28-2018 with and without cranes

Canadian bridge design code S6-19

Proposed EC7 updated with significance factor


Seismic Analysis Options

Including cohesion effects can reduce the total seismic demand with these two methods:

RichardsShi solution for soils with both cohesion and friction

Machairas - Iskander solution for soils with both cohesion and friction


Frame analysis (3D walers)

Visualization speed improvements.

Weld and connection generation improvements.

Options for reducing waler moments by modelling bracing reactions at strut edges.

Viewing increment option for 3D models.

Waler extensions to struts, extend walers at connections. Connect struts to waler extensions for complex geometries.

Digital Twin City Data

Import buildings from DXF and CadMapper, import utility lines from QGIS dxf files. Tools allow you to easily import utility lines for damage assessment.

Planning level analysis with damage assesment for subway projects

City Module & Ground Data

  • Transportation level analysis based on Google API, MapQuest, and other methods. With this tool you can quickly provide planning level estimates for travel times to new stations, number of people served withing 5, 10, 15 min time intervals and overall subway project benefits.

  • Improved global settlement large scale analysis

  • Trimming of imported ground surface data

  • Importing of ground elevations from dxf files

  • Improved quick estimation for subway lines and quick subway project cost estimates.

Slope stability for reinforced earth embankment

Soil reinforcements

  • Steel grids and strips, geogrids, geotextiles for slope stabilizations

  • Stone columns and adaptive soil improvement. Stone column shear strength calculation from replacement ratios.

  • Embankment Wizard with loading, geo-reinforcements, train loading, stone columns, etc.

Wall Sections

  • Double H-Beam soldier pile and secant pile walls

  • Corrugated sheeting two-flange and four flange, with support for CONTEC and DSI underground sections. Special methods available for circular shafts with corrugated sheeting. Wizard added for quick generation of circular corrugated sheeting excavations.

  • Base wall footing option added.

Corrugated sheet pile design for deep excavations

Slope Stability

- Improvements in slice generation for more accurate differentiation for layer intersections, stone columns, soil zones.

- Soil reinforcements such as geogrids, geotextiles, steel strips.

Finite Element Analysis Upgrades

- Improved speed and convergence.

- Improved algorithms for load combinations and standardization of loads for EC7 and other combinations.

- Dynamic analysis and time history options.

- Groundwater drawdown analysis.

- Automatic adjustment of properties at stone columns based on area replacement ratio.

Damage Assessment

Damage assessment for utilities with cost estimation and disruption level analysis. Estimating the settlements from tunneling and excavations, the program can assess the potential impact on existing utilities, determine service level disruptions, and potential costs. This large data feature allows for the quick study of the impact of large scale tunneling works on existing underground utility infrastructure.

Gravity Wall Analysis Options

Additional options for selecting support force reactions independent from slope stability analysis. Service reactions, allowable resistance, or ultimate resistances can be selected.

Multivariate Optimization

Improvements for multivariate optimization with wall sizes and other options.


New report templates, more condensed detailed calculation outputs, general report improvements.

Soil strength profiles

User specified Su, OCR elevation profiles. Allows for the specification of exact Su strengths and OCR values with elevation for cities such as Boston, etc.
