Temporary Support of Excavation Design​

Practical, buildable solutions for safe and efficient below-grade construction ​

D.W. Kozera, Inc. provides design services for temporary and permanent excavation support systems that balance safety, constructability, and cost. Our geotechnical engineers work directly with contractors, structural engineers, and design-build teams to develop systems that fit the site conditions, construction phasing, and project goals, helping teams complete below-grade work safely and efficiently. ​

Whether your project requires support for a deep foundation, utility corridor, or multi-story basement, we design excavation support systems that are both technically sound and contractor-friendly. With expertise in a wide range of shoring and retention methods, from traditional cantilevered sheeting to complex braced, anchored, or tied-back systems, we tailor each design to the excavation depth, adjacent structures, and soil/groundwater conditions. ​

Services Offered ​

  • Excavation Support Design for Basements, Utility Trenches, and Deep Foundations ​
  • Soldier Pile and Lagging Systems ​
  • Steel Sheet Pile and Cantilever Wall Systems ​
  • Braced, Raker, and Tieback Shoring Designs ​
  • Temporary Support of Adjacent Structures ​
  • Slope Stability and Global Stability Analysis ​
  • Construction Sequencing and Dewatering Considerations ​
  • Coordination with Field Instrumentation and Monitoring ​

Why Work with D.W. Kozera? ​

  • Buildable Designs Grounded in Field Experience ​
    Our support systems are engineered with real-world constraints in mind, making them easier to install, phase, and adapt on active construction sites. ​
  • Geotechnical Expertise Backed by Regional Soil Knowledge ​
    With decades of experience across the Mid-Atlantic, our team delivers excavation designs that account for local soil behavior, groundwater, and adjacent structures. ​
  • Close Coordination from Preconstruction Through Removal ​
    Whether part of a design-build team or supporting a GC directly, we stay engaged through all phases of your project, aligning designs with your construction plan, schedule, and safety needs. ​

With a deep foundation in geotechnical engineering and a hands-on understanding of construction logistics, D.W. Kozera delivers excavation support designs that help your project dig deeper safely and effectively. Contact us today to discuss support system options or request a design proposal. ​
