GENERAL REQUIREMENTS

In case of conflicts between the applicable ACI and ASTM Standards and this Practice, the most stringent requirements shall govern.

The Manufacturer shall furnish all plant, labor, materials, tools, and equipment, and perform all operations and incidentals necessary for the furnishing, detailing, fabricating and delivering to the jobsite of reinforcing steel as specified herein and shown on design drawings.

MATERIALS AND FABRICATION

Materials shall be selected in accordance with EP 4-3-1.

Fabrication

Detailing and fabrication of all reinforcing steel shall be in accordance with ACI 315. Tolerances shall be per Chapter 7 of CRSI MSP-2.

Reinforcement shall not be welded.

Laps or splices shall conform to ACI 318. Welding shall not be permitted for splicing reinforcing bars #11 and smaller. The minimum lap splice of wire fabric shall be in accordance with EP 4-3-2.

5.1.4 Hot bending is not permitted.

Identification and Marking
All reinforcing steel shall be bundled and identified with metal tags marked in a legible manner. No less than one tag shall be wired to each bundle. Identification tags shall show the grade, the size, the length of the bars, the piece mark, the related design drawing number, and the heat number. Any bundles not so tagged shall be rejected.
(*)Material shall be identified to insure traceability of each group of bars to its certified mill test report during fabrication, while in transit, and when delivered. A record of identification shall be submitted by the fabricator.
Welded wire fabric shall be rolled for shipment and marked in accordance with Paragraph

5.3.1 of this Practice.

Workmanship
Material so improperly fabricated as to create extra placing work in the field shall be the responsibility of the Manufacturer. The Manufacturer shall pay the entire cost of replacement, or of field corrections, including all shipping costs.
The Manufacturer shall repair or replace, at his own expense, any material damaged in transit before delivery to jobsite. When it is impractical to return defective material to the Manufacturer's shop, or when the construction schedule does not permit it, the Manufacturer shall make the necessary repairs in the field.

INSPECTION

The Owner reserves the right to inspect materials and workmanship at the Manufacturer's plant.
(*)When requested by the Owner, three copies of mill test reports shall be furnished by the Manufacturer.
Inspection by the Owner shall not relieve the Manufacturer of responsibility for compliance with all requirements of this Practice.
The Manufacturer's service shall include inspection by his own shop inspector.
The Manufacturer shall provide facilities, including drawings, for shop inspection of materials and workmanship to the Owner.

DOCUMENTATION

Drawings
(*)The Owner's Engineer will furnish copies of design drawings covering all data required for preparation of shop details and placing drawings for the reinforcing steel.
The Manufacturer shall prepare and submit for the Owner's Engineer information, prints and a reproducible of each placement drawing and associated bar bending schedule. The bar bending schedule shall include, as a minimum, types, sizes, and quantities of bends and splices and shall reference the related placing drawing. The placing drawings shall reference the Owner's design drawings.
The Manufacturer shall submit a drawing Control Log identifying the title, items shown, sequence number, scheduled date of issue, and revision number of each placing drawing and bar bending schedule.
(*)The Owner's Engineer will review the Manufacturer's placement drawings and bar bending schedules to verify compliance with this specification and the design drawing. The Manufacturer shall be responsible for the completeness and accuracy of all dimensions and details and for conformance of materials to the requirements of this specification.

7.2 Mill Test Reports

(*)For each heat or mill shipment, whichever is less, the Manufacturer shall furnish to the Inspector three certified copies of mill test reports covering the chemical and physical properties of the reinforcing steel, as specified in the referenced specifications and standards. Each delivery shall be identified by its applicable mill test report and heat number. The reports shall be submitted to the Inspector at the time of steel delivery to the fabrication shop. Proceeding with fabrication prior to approval of the Inspector will be at the Manufacturer's risk.
