Field Testing of Concrete performed:Yes
*CYLINDER SET NO:792-187 to 792-188 *Refer to associated concrete test report
Notes:
As requested by CDM Smith, S.W.COLE rep. 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 6:20 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 135 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 2 and 10 of the concrete placement. Field-testing services were
performed in general accordance with applicable ASTM test procedures. Concrete test
specimens were fabricated for subsequent compressive strength testing at 7-day, 14-day, and
two 28-day intervals, with one specimen retained as a hold sample. [You Need t...Skills.pdf |

Based on the field-testing performed, the measured concrete properties were observed to fall
within the project-specified acceptance ranges.
Test results and observations were verbally reported to Rayssa Fonte of CDM Smith while
onsite.
Upon completion of the requested services, the S.W.COLE rep. departed the site at
approximately 10:35 AM.
