Notes:
As requested by Wright-Pierce, S.W. Cole representative Riley Nordahl was onsite to perform
concrete field-testing services associated with the referenced concrete placement.
S.W. Cole Engineering Construction Services Technician Riley Nordahl arrived onsite at
approximately 6:25 AM.
Upon arrival, the S.W. Cole representative met with Rayssa Fonte of CDM Smith, who provided
an overview of the planned work activities for the day.
Concrete was supplied by Cape Cod Ready Mix and was reported to consist of 3/4-inch
nominal maximum aggregate, 4,500-psi concrete with Sika Control 75 admixture.
Approximately 4 cubic yards of concrete were placed during the observation period.
Concrete samples used for field testing and fabrication of compressive-strength test
specimens were obtained from Load No. 1. Field-testing services were performed in
general accordance with applicable ASTM test procedures.
Concrete test specimens were fabricated for compressive-strength testing at 7-day, 14-day,
and three 28-day intervals. One additional specimen was retained as a hold sample.
Field Test Results – Load No. 1
Slump: 3 inches
Air Content: 3.5%
Concrete Temperature: 81°F
