The Geotechnical Section consists of four areas that provide soil testing services as well as drilling and complete geotechnical engineering services.

Compaction Laboratory 
Tests soils for relative compaction. Certified personnel conduct field in-place density tests using both the nuclear gauge and sand cone methods. Soil is tested for lab maximum density and optimum moisture content.

Foundation & Classification Laboratory 
Performs soil tests including particle size, Atterberg limits, direct shear, consolidation, triaxial, California Bearing Ratio, R-value, and permeability.

Special Projects Unit
Inspects and monitors earthwork construction activities such as excavations and backfill compaction. This group performs fill certifications, coordinates soil testing and provides geotechnical engineering analyses and recommend
