Notes:
As requested by Eric (CDM Smith), S.W.COLE rep was onsite to perform construction
observation services, including concrete sampling and testing, during placement operations at
the project site.
The S.W.COLE rep arrived onsite at approximately 6:30 AM and departed at approximately
11:30 AM after completing the requested observation, sampling, and testing services.
Concrete placement activities were ongoing during the time the S.W.COLE rep was onsite
performing services.
Concrete Delivery No. 1 arrived onsite consisting of approximately 11 cubic yards of 4,500-psi
concrete with 1-1/2-inch aggregate.
Sika 75 admixture was reported to have been added prior to placement.
The concrete was placed via pump truck.
Two sets of field tests were performed on sampled concrete with the following results:
Truck 52 – Load 2
• Slump: 6 inches
• Air Content: 3.5 percent
• Concrete Temperature: 77°F

Truck 51 – Load 10
• Slump: 7 inches
• Air Content: 4.2 percent
• Concrete Temperature: 77°F
Two sets of compression test cylinders were cast for laboratory testing at 7, 14, and 28 days
(two cylinders per test age), along with one hold cylinder.
Laboratory compressive strength test results will be reported separately upon completion of
testing.
Concrete Delivery No. 2 arrived onsite consisting of approximately 11 cubic yards of 4,500-psi
concrete with 3/4-inch aggregate. Sika 75 admixture was reported to have been added prior

One set of field tests was performed on sampled concrete with the following results:
Truck 67 – Load 1
• Slump: 6.5 inches
• Air Content: 3.2 percent
• Concrete Temperature: 79°F
One set of compression test cylinders was cast for laboratory testing at 3, 7, 14, and 28 days
(three cylinders per test age), along with one hold cylinder. Laboratory compressive strength
test results will be reported separately upon completion of testing.
Test results and observations were verbally reported to Eric (CDM Smith) while onsite.
