<br /> Failure to meet the requirements of this Specification or the QCP will
<br /> automatically void the concrete portion of the QCP . To obtain QCP re -approval, implement
<br /> corrective actions as approved by the Engineer . The Engineer may allow the Contractor to
<br /> continue any ongoing concrete placement but the Engineer will not accept concrete for any new
<br /> placement until the QCP re-approval is given by the Engineer.

<br /> with each batch of concrete before unloading at the placement site . The delivery ticket may be
<br /> proprietary software or in the form of an electronic spreadsheet, but shall be printed . Ensure that
<br /> the materials and quantities incorporated into the batch of concrete are printed on the delivery
<br /> ticket . Include the following information on the Delivery Ticket :
<br /> ( 1 ) Arrival time at jobsite ,
<br /> (2) Time that concrete mix has been completely placed,
<br /> (3 ) Number of revolutions upon arrival at the jobsite ,
<br /> (4) Total gallons of water added at the jobsite,
<br /> (5 ) Additional mixing revolutions when water is added,
<br /> (6) Total number of revolutions at mixing and agitating speed.
<br /> Items 3 through 6 do not apply to non- agitating concrete transporting vehicles .
<br /> Ensure the batcher responsible for production of the batch of concrete signs the
<br /> delivery ticket, certifying the batch of concrete was produced in accordance with the Contract
<br /> Documents .
<br /> Verify that the chloride test results on the delivery ticket meet the requirements of
<br /> Table 4 .
<br /> Sign the delivery ticket certifying that the design mix maximum specified water to
<br /> cementitious materials ratio was not exceeded due to anyjobsite adjustments to the batch of
<br /> concrete, and that the batch of concrete was delivered and placed in accordance with the Contract
<br /> _ Documents .
<br /> SUBARTICLE 346- 6 . 4 (Pages 329 — 330 ) is deleted and the following substituted :
<br /> 3464.4 Plastic Property Tolerances : Do not place concrete with a slump more than
<br /> It plus or minus 1 . 5 inches from the target slump value specified in Table 2 .
<br /> Reject concrete with slump or air content that does not fall within the specified
<br /> tolerances and immediately notify the concrete production facility that an adjustment of the
<br /> concrete mixture is required so that it will fall within specified tolerances . If a load does not fall
<br /> within the tolerances , test each subsequent load and the first adjusted load. If failing concrete is
<br /> not rejected or adjustments are not implemented, the Engineer may reject the concrete and
<br /> terminate further production until the corrections are implemented.
<br /> Do not allow concrete to remain in a transporting vehicle to reduce slump . Water may be
<br /> added only upon arrival of the concrete to the jobsite and not thereafter .
