Notes:
As requested by Rayssa, 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 6:20 AM and departed at approximately

Concrete Delivery No. 1
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.
One sets of field tests were performed on sampled concrete with the following results:
Truck 51 – Load 2
Slump: 8 inches
Air Content: 3.0 percent
Concrete Temperature: 75°F
One set 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.
