- 4 - 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 ofPage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 Next
