Notes:
As requested by Wright-Pierce, S.W. COLE rep. Andrew Carter, Construction Services
Technician, arrived onsite at approximately 6:22 AM to observe concrete placement activities
and perform field testing. Upon arrival, S.W. COLE rep. met with Allen Sulc, representative of
Wright-Pierce, to discuss the planned concrete placement activities for the day.
Concrete was supplied by Cape Cod Ready Mix. The concrete was reported to be a 1½-inch
nominal aggregate, 4,500-psi design mix. Approximately 55 cubic yards of concrete were
placed during the observation period. Concrete sampling and field testing were performed in
general accordance with applicable ASTM standards.
Samples were collected from the first load delivered to the site. The following results were
obtained from the first load:
First Poured Load – Truck No. 81
Slump: 6 inches
Air Content: 3.8%
Concrete Temperature: 80°F
Concrete placement activities were observed utilizing a pump truck and internal consolidation
activities were observed utilizing a worm-type internal vibrator.
A total of five (5) 6" x 12" concrete cylinders were cast from the first load for laboratory
compressive strength testing, consisting of one (1) cylinder for 7-day testing, one (1) cylinder
for 14-day testing, and two (2) cylinders for 28-day testing. One (1) additional cylinder was
designated as a hold specimen.
Field test results and observations were verbally communicated onsite to Allen Sulc,
representative of Wright-Pierce, at the time of testing.
