1.04 QUALITY ASSURANCE:

A. Welder Qualifications: As a minimum, the welder shall meet the qualifications for: Electrodes up to and including E 7018; Steel thickness 1/8- to 3/8-inch; fillet, groove, low-hydrogen welding; or meet code qualifications for structural plate and rolled structural shapes.

PART 2: PRODUCTS

2.01 MATERIALS:

A. Cattle Guard Grids: Shall be constructed of materials as shown on the drawings and described in these specifications. Design loading of grids shall conform to AASHTO HS-20 for BLM grid and dimensions shall be as shown on the drawings and the Work Data Sheet.

1. New material shall be used in the fabrication of cattle guards.

B. End Wings: Shall be as shown on the drawings.

C. Rough treated 12x12 rough treated CCA.4 ponderosa pine 16 ft timbers

2.02 FABRICATION:

A. Steel Cattle Guard Grids: Steel grids shall be all-welded construction. Welds shall be secure and complete along both edges of cross pieces and at joints in the frame and shall conform to AWS

D1.1. Welding shall be performed according to a welding procedure specification (See AWS D1.1) which has been approved by the Contracting Officer.

B. Paint: Structural steel shall be cleaned according to SSPC SP-6, Commercial Blast Cleaning.

Cattle guard grids and end wings shall each receive a prime and finish coat. The prime coat shall be a lead free, zinc-rich, rust-inhibitive alkyd metal primer. Minimum thickness shall be 1-1/2 mils dry-film thickness (DFT). The finish coat shall be an oil alkyd-enamel, gloss paint. Minimum thickness shall be 3 mils DFT, applied in two applications. Color shall be Federal Safety Yellow or match color no. 13655, FS 595. Cattle guards shall be painted after fabrication.

2.03 SOURCE QUALITY CONTROL:

A. Plant Inspection: The contractor's manufacturing facility shall be open to the Contracting Officer during normal hours. There shall be a Contractor's Representative on the site to answer questions.

B. Material Marking: Material to be used in the fabrication process shall be labeled, marked, or otherwise segregated from differing material.

C. Weld Inspection: The quality of the weld shall be "acceptable" under the visual requirement of

AWS D1.1, AWS B1.10, and AWS WI, CH16. Unacceptable welds or defects in the welds as detected by visual inspection or by radiographic, penetrant dye, or magnetic particle techniques shall be repaired or removed and replaced by methods acceptable under the applicable AWS welding codes, or the entire piece may be rejected by the Contracting Officer. Repaired or replaced welds shall be re-inspected by the applicable nondestructive testing method.

D. Sandblast Inspection: The Contractor shall notify the Contracting Officer when and where the grids shall be sandblasted so that the Contracting Officer will arrange an inspection of the sandblasting quality prior to paint application.
