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 5:20 AM. Upon arrival, the S.W.COLE rep. 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 consisted of 1-1/2-inch, 4,500 psi concrete with Sika Control 75 as an additive. Approximately 301 cubic yards of concrete were placed during the observation period. Concrete samples for field-testing and fabrication of compressive strength specimens were obtained from Loads 1,10,19 and of the placement. Field-testing services were performed in general accordance with applicable ASTM test procedures. Concrete test specimens were fabricated from the sampled concrete for subsequent laboratory compressive strength testing at one 7-day interval, one 14-day interval, and two 28-day intervals. One additional specimen was retained as a hold sample.
