Notes:
As requested by Wright-Pierce, S.W. COLE rep Andrew Carter, Construction Services Technician, arrived onsite at
approximately 0655 AM to observe concrete placement operations 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 Code Ready Mix. The concrete was reported to be a 3/4‑inch nominal aggregate,
4,500‑psi design mix. A total of approximately 99 cubic yards of concrete was 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. 74
Slump: 5.25 inches
Air Content: 3.3%
Concrete Temperature: 81°F
Concrete placement was observed to be performed using a pump truck. Internal consolidation was observed
using a worm‑type internal vibrator. Concrete spreaders were observed to be used to spread the concrete, and
hand trowels were observed to be used to level and finish the surface. The 2 columns on the east of the
headworks building and the process footing support wall were left to be poured. AJC had to depart to report to
another job. Allen verbally told AJC that only one test was required although there was more than 100 cubic
yards placed (only 99 cubic yards were observed by AJC).
A total of five (5) concrete cylinders were cast from the first load for laboratory compressive strength testing,
consisting of one (1) cylinder at 6 days, one (1) cylinder at 14 days, and two (2) cylinders at 28 days. One (1)
additional cylinder was designated for hold purposes.
Field test results and observations were verbally communicated onsite to Allen Sulc, representative of Wright-
Pierce, at the time of testing.
