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.

TYPE III - 7.8 m RDY.

FABRICATOR SHALL PROVIDE

REQUIRED DESIGN STRENGTH

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.

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.

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.

TREATMENT OF CUT STRANDS: All cut off strands that will be exposed are to be coated with

two coats of an approved zinc rich paint (minimum 80 m). 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.
