Notes:
As requested by Rayssa (CDM Smith), S.W.COLE rep was onsite to observe concrete placement
and perform concrete sampling and testing at the locations referenced above.
The S.W.COLE rep arrived onsite at approximately 6:30 AM. Concrete placement activities were
observed during the time of sampling and testing. Observations were limited to conditions
present and activities occurring at the time of the site visit.
One concrete delivery was observed during the site visit. Concrete Delivery No. 1 arrived
onsite consisting of approximately 10.5 cubic yards of 4,500‑psi concrete with 1‑1/2‑inch
nominal aggregate. The concrete reportedly included Sika® 75, which was added prior to
arrival. The concrete was placed via pump truck.
One set of field tests was performed on the sampled concrete with the following results:
Truck 53 – Load 1Slump: 8.5 inches
Air Content: 4 percent
Concrete Temperature: 70°F
One set of compression test cylinders was cast for laboratory testing at 7, 14, and 28 days (two
cylinders per test age), along with one hold cylinder. Test results will be reported separately
upon completion of laboratory testing.
Test results and field observations were verbally reported to the onsite Justin while onsite.
The S.W.COLE rep departed the site at approximately 9:15 AM after completing the requested
services.Attachments: 2 Photos Reviewed by:5/18/2026 Kaylie OSu iv Kaylie OSullivan
