Mr. Hiser:
As you requested, during the period from January 6 through January 25, 2000, Earth Engineering
Consultants, Inc. (EEC) personnel provided construction observation and testing services for the
referenced project. Those services were provided on a part-time, on -call basis and included
observation and testing of post -tensioned slab construction for the referenced project. Results
of the post -tensioned slab observations completed by EEC personnel on the referenced dates are
included with this report.
When requested, EEC personnel observed and tested Portland cement concrete delivered to the
site for placement in the post -tensioned slab foundations. The tests completed on the plastic
concrete included slump, air content, and concrete temperature. The ambient air temperature at
the time of placement was also recorded. Concrete test cylinders were cast from representative
samples of the plastic concrete for laboratory curing and compressive strength testing. Results
of the field and laboratory testing are being provided in separate reports.
