Concrete testing consisted of primarily compressions tests
to check specifications and density of freshly poured concrete in
the field. Tests were conducted on concrete core samples or 6 x
12 cylinders created by petitioner’s technicians or brought in by
third party contractors.
Petitioner also tested soil samples for moisture contents,
density determinations, shear strengths, permeability tests,
proctor tests, and other tests. Soil borings, and sometimes rock
core borings, were obtained to classify the type of soil or rock
substance. To conduct a soil density test technicians in the
field used nuclear meters to determine the density of materials
for earthwork projects. Training to read the meter was done on
the job in approximately 30 minutes. Technicians handled all
aspects of obtaining samples, drilling, or laboratory testing.
In both concrete and soil testing, information collected
from a test was given to clerical staff. Upon request by a
client, an engineering analysis could be generated from the test
results. Otherwise, the data was given to the client in a report
written by the clerical staff without analysis. Only technical
personnel conducted and collected data from geotechnical tests.
It was not the function of the engineers to create or test the
cylinders or core samples.
Petitioner also provided engineering services. Engineering
services included offering recommendations on types of
