Leveraging DeepEX for High-Performance Support of Excavation Systems
The successful delivery of a deep excavation for a major pump station facility in Austin, Texas stands as a strong example of how advanced numerical modeling and design optimization can drive both technical excellence and project efficiency.
With excavation depths exceeding 100 feet, the project required a highly engineered support system capable of addressing complex geotechnical and structural challenges in a constrained urban environment.

Engineering Challenges
The design team at KELLER was faced with a demanding combination of factors:
Interaction with adjacent infrastructure and restricted site access
Variable subsurface stratigraphy and rock profiles
Strict deformation and performance criteria
Multiple potential failure mechanisms requiring verification
Construction sequencing constraints across different excavation depths
To meet these challenges, a multi-level support of excavation system was developed, combining different support mechanisms adapted to changing ground conditions and excavation geometry.

DeepEX as a Core Design Platform
DeepEX was used as the primary analysis and design platform throughout the project. Its capabilities enabled a rigorous and efficient evaluation of the excavation system, including:
Soil-structure interaction modeling using advanced earth pressure formulations
Staged construction analysis, capturing the full excavation sequence and support activation
Wall performance evaluation, including bending moments, shear forces, and deflection profiles
Support system response, with detailed assessment of load distribution and structural demand
Global and local stability checks, addressing multiple potential failure modes
The ability to integrate all these checks within a unified environment allowed the engineering team to maintain consistency across analyses while reducing the need for fragmented calculations or external tools.
Rapid Iteration and Design Optimization
One of the key advantages of DeepEX in this project was the ability to quickly evaluate and compare alternative design scenarios.
Engineers at KELLER were able to:
Perform parametric studies to understand system sensitivity
Assess critical loading combinations and worst-case scenarios
Refine the support configuration to balance performance and constructability
Optimize the overall system while maintaining compliance with design criteria
This iterative workflow significantly accelerated the design process and enabled data-driven decision-making at every stage.
Delivering Measurable Project Value
The use of DeepEX extended beyond technical validation—it directly contributed to project success:
Optimized support configuration, reducing unnecessary conservatism while maintaining safety
Improved constructability, aligning design with field constraints and sequencing
Enhanced bid competitiveness, through efficient and well-justified solutions
Increased confidence, supported by comprehensive analysis and verification
By enabling a more refined and efficient design approach, DeepEX helped KELLER transform a highly challenging excavation into a feasible and economically viable solution.

Clear Communication and Team Alignment
DeepEX also facilitated effective communication across the project team. Its structured outputs and clear visualization of results allowed engineers to:
Present design assumptions and results transparently
Support discussions with stakeholders and decision-makers
Provide a clear basis for construction planning and execution
A Proven Tool for Complex Excavations
KELLER emphasized the importance of combining advanced software with strong technical support. The reliability of DeepEX, along with responsive expert assistance, played a key role in addressing project challenges and maintaining design momentum.
Conclusion
This project highlights how modern excavation design requires more than traditional methods—it demands integrated analysis, rapid iteration, and optimization capabilities.
DeepEX provides engineers with the tools to:
Tackle complex soil-structure interaction problems
Evaluate multiple design scenarios efficiently
Optimize systems for both performance and cost
Deliver confident, high-quality excavation designs
For challenging deep excavations, DeepEX is not just a calculation tool—it is a comprehensive engineering platform that enables better decisions and better outcomes.
