Capabilities
Geotechnical & Drilling
Subsurface investigation, drilling, foundation engineering, and geotechnical analysis for commercial and government projects.
Our Approach
How We Deliver
PRD provides geotechnical and drilling services that characterize subsurface conditions, support foundation and earthwork design, and reduce uncertainty during planning and construction.
Field-verified data
Drilling, sampling, and testing practices that produce reliable subsurface profiles for design and permitting.
Design integration
Close coordination with designers and contractors so geotechnical recommendations are practical and buildable.
