The production schedule shall be documented and adhered to such that the blocks may be inspected and tentatively approved or rejected by the Contracting Officer.

3.2 FORMING, CASTING AND HANDLING UNITS

3.2.1 Each block shall be cast in one continuous operation. There shall be no cold joints.

3.2.2 Consolidation: Immediately after placing concrete, the plastic concrete shall be consolidated by internal or external formwork vibrating equipment. Vibrators shall not be used to transport concrete within the forms. The vibrating equipment shall be adequate in number of units and power to properly consolidate the concrete. Concrete shall be consolidated in horizontal layers 18 inches or less in thickness.

3.2.3 The Contractor shall be responsible for maintaining the soundness of castings: The contractor shall devise and adhere to schedules and procedures for manufacturing, handling and storing blocks in a manner that will not induce latent weakness in the units. In the event the Contracting Officer's Representative finds cause to question the structural adequacy of any block for any reason of method or occurrence that is within the Contractor's control, it shall be the Contractor's responsibility to demonstrate the acceptability of the precast unit. Any block found structurally unsound, in the opinion of the Contracting Officer's Representative, will be rejected and shall be promptly removed from the point of final delivery at the Contractor at his expense.

3.2.4 Surface Requirements:

3.2.4.1 A magnesium trowel finish is required and after consolidation, screeding and floating of the concrete.

3.2.4.2 Maximum allowable surface irregularities shall not exceed ½ inch.

3.2.4.3 Lifting and Handling: The Contractor shall exercise caution when removing the concrete units from the formwork. The concrete must attain a minimum of 2000 psi (f’c) prior to handling the units by way of the lifting eye system. The handling or movement of the units shall not damage or otherwise adversely affect the structural qualities of the units. Any unit damaged due to early handling will not be accepted.

3.2.5 Hot Weather Concrete Placement: If concrete is proposed to be placed under hot weather conditions, the materials and methods will be provided in accordance with the requirements of ACI 305 and the Contractor’s submitted and approved procedures. The concrete placing temperature shall not exceed 90 degrees F. Cooling of the mixing water and/or aggregates will be required to obtain an adequate placing temperature. An approved retarding admixture may be used to facilitate placing and finishing.

3.2.6 Cold Weather Concrete Placement: If concrete is proposed to be placed under cold weather conditions, the materials and methods will be provided in accordance with the requirements of ACI 306 and the Contractor’s submitted and approved procedures. Concrete shall not be subjected to freezing temperatures before it reaches minimum required compressive strength (4000 psi).

• For Commercial/Industrial Use Only • Page 1 of 2

P-60 Swift Lift Tension Bar Installation The proper installation of a tension bar is as follows:

1) Place the tension bar through the eye of the anchor in such a manner that the tension bar contacts the bottom of the eye.

2) Make certain the legs of the tension bar are equal on either side of the anchor.

3) Wire the tension bar into position so that the tension bar stays in contact with the bottom of the eye.(See sketch below.)

DO NOT attempt to use field-bent bars as a replacement for the Dayton Superior P-60 Tension Bar. Field bending may result in an improperly shaped tension bar, an incorrect radius and/or a cracked bar. A problem, such as this, can cause the field-bent tension bar to fail prematurely.

Right

Wrong

The Dayton Superior Swift Lift Tension Bar (P-60) is designed to be used with the P-53 Eye Anchor in order for the eye anchor to develop its published rated working loads. See P-60 sizes and dimensions below.
