*CYLINDER SET NO:792-206 to 792-207 *Refer to associated concrete test report
Notes:
As requested by Wright Pierce S.W.COLE rep Henry was onsite to observe concrete placement
activities and perform concrete testing.
Ready-mix concrete trucks began arriving onsite at approximately 5;30 a.m. Delivery tickets
were reviewed for concrete mix designation, batch time, truck number, aggregate size, and
delivered quantity.
For the Exterior wall, concrete was supplied by Cape Cod Ready Mix concrete and was
reported as a 4500-psi mix incorporating 1"1/2-inch nominal maximum aggregate. (2) loads of
concrete approximately (23) cubic yards of concrete were reported to have been placed during
this operation.
For the staircase , concrete was supplied by Cape Cod Ready Mix concrete and was reported
as a 4500-psi mix incorporating 3/4-inch nominal maximum aggregate. (1) loads of concrete
approximately (10) cubic yards of concrete were reported to have been placed during this
operation.
Concrete was discharged and transported to the placement area using a concrete pump by
Marguerite Concrete . Placement operations were observed throughout the area, including
areas adjacent to openings and corners. Concrete consolidation was performed using an
internal vibrator and manual methods where necessary.
During the observation period, no significant segregation or excessive bleeding was observed
in the concrete being placed.

For the exterior wall, field concrete testing was performed during placement. Samples were
obtained from Truck Nos. 60. Five (5) 6-inch by 12-inch concrete compression test cylinders
were prepared of concrete placement for subsequent compressive strength testing.
For the staircase, field concrete testing was performed during placement. Samples were
obtained from Truck Nos. 83. Six (6) 4-inch by 8-inch concrete compression test cylinders were
prepared of concrete placement for subsequent compressive strength testing.
