Reliable design input and testing support for shallow and deep foundation systems
Accurate foundation recommendations are critical to structural performance, budget control, and long-term reliability. D.W. Kozera, Inc. delivers geotechnical evaluations, load testing, and construction-phase observation to support a full range of foundation systems, front spread footings, to driven piles and drilled shafts. Our engineers provide clear, site-specific guidance to help design teams select appropriate foundation types and assist contractors in verifying performance during installation.
Core Services
- Shallow Foundation Design Recommendations
Site-specific evaluation of bearing capacity and settlement behavior for spread footings and mat foundations, helping support efficient structural design and avoid over-conservatism. - Deep Foundation Design Support
Design parameters and installation criteria for driven piles, drilled shafts, auger cast piles, and micropiles, developed with soil-structure interaction and constructability in mind. - Pile Load Testing and Performance Evaluation
Coordination and interpretation of static and dynamic pile load tests (PDA, CAPWAP, and static load), offering reliable confirmation of design assumptions and construction quality. - Foundation Observation During Construction
On-site observations of foundation bearing surfaces and pile installations to confirm that field conditions align with design expectations and support timely decision-making. - Low-Strain and Non-Destructive Integrity Testing (PIT, CSL, TIP)
Post-installation testing to assess foundation element continuity and detect anomalies such as voids, necking, or poor concrete placement without destructive excavation.
