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.
