Safe, staged excavation support through geotechnical design and construction guidance
Deep and temporary excavations come with unique geotechnical risks. D.W. Kozera, Inc. provides excavation support system design, stability evaluations, and groundwater control recommendations to help teams complete earthwork safely and efficiently. Whether you’re working in an urban footprint or near sensitive infrastructure, we tailor excavation designs to your site, sequencing plan, and safety requirements.
Core Services
- Temporary Support of Excavation (SOE) System Design
Designs for soldier pile and lagging walls, sheet piles, and braced or tieback systems that account for soil behavior, site access, and structural loads—ensuring safe excavation while minimizing disruption. - Global and Internal Stability Analysis
Stability modeling for retained soil systems and excavation slopes under static and seismic conditions, helping manage risk and validate designs against movement and failure. - Adjacent Structure Monitoring
Assessment of potential movement impacts on neighboring buildings, utilities, and infrastructure, with recommendations for monitoring and mitigation strategies to reduce risk during excavation. - Construction Phasing and Access Planning
Support for temporary excavation layouts and stepwise construction sequences that maintain safety and allow continuous work in constrained or staged construction zones.
