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.

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

Drilling Unit
Unit provides drilling, logging, and sampling services for subsurface investigation. Full laboratory support is available for testing soil engineering properties and possible chemical contamination. Other services include well installation and well abandonment.

Geotechnical Engineering 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 recommendation. Seismic testing on unreinforced masonry buildings is also available.
