SPECIFICATIONS FOR STEEL STRANDS: Grade 270, 7-wire, uncoated, low

relaxation steel strand shall conform to the requirements of AASHTO M203

(ASTM A-416) and Supplement I.

STRAND: All strands shall be the size and type as shown on the Plans. Initial

load per strand shall be 75% of the breaking strength of the strand for low

relaxation strand.

Painting to be done by fabricator.

SHOP DRAWINGS: The Contractor shall have his Prestressed Concrete Beam

Fabricator furnish the Bridge Engineer, for his approval, two sets of checked shop

drawings. Shop drawings shall show the casting length center to center of

bearings, and the calculated prestress shortening. One copy shall be returned to

the fabricator with any desired corrections indicated. The fabricator shall then

furnish the Bridge Engineer with as many, generally seven, corrected copies of the

shop drawings as may be required for approval and distribution. The approval

of the shop drawings in no way relieves the Contractor or his fabricator of the

responsibility for mistakes on the shop drawings.

PRESTRESSED CONCRETE BEAMS:

CHAMFER REQUIREMENT: Chamfer all exposed edges of P.C. Beams 19mm unless

otherwise noted.

FORMS & PALLETS: All beams shall be cast in concrete floored pallets and metal

forms.

FINISH: Top of beams to be rough floated. At approximately the time of initial

set, entire top of beam shall be scrubbed transversely with coarse wire brush to

remove all laitance and to produce a roughened surface for bonding slab.

CEMENT: Type I or III Portland Cement may be used for the Prestressed Concrete

Beams.

HANDLING: In the handling of the beams, they must be maintained in an

upright position at all times and must be picked up from the lifting eye

provided at the beam ends. Disregard of this requirement may lead to collapse

of the member.

The Prestressed Concrete Beams may be redesigned to use "Debonded" and or

15 mm strands rather than the "Draped" strands shown. The New Design and

Structural Calculations for "Debonded" and or 15 mm strands must be prepared

by and sealed by a Professional Engineer registered in the State of Oklahoma

and submitted to the Bridge Engineer for approval.

If "Debonded" Strands are used the "U" bars shall extend an additional

1200 mm, toward the middle of the span, just past the point of debonding.
