Notes:
S.W. Cole Engineering Construction Services Technician Robert Reuter arrived onsite at 5:15 AM for "Concrete Field Testing"
and for the placement location referenced above. Upon arrival, met with Eric Salo with CDM Smith who provided information
about today's job duties.
Concrete was delivered by "Cape Cod ready mix." and was 3/4” & 1-1/2” 4500 PSI Concrete. A total of (200) cubic yards of
concrete was placed.
A sample was collected from load (1) of the 3/4”concrete. Loads (1) of the 1-1/2”. Loads and the standardized testing was
performed with; one set of 1-1/2” (5) cylinders were cast from the load for laboratory compressive strength testing at 7, 14,
and (2) 28 days. One cylinder was made for 'Hold' purposes. Two sets of 3/4” (6) cylinders were cast
from the load for laboratory compressive strength testing at 7, 14, and (3) 28 days. One cylinder was made for 'Hold'
purposes.
