9.1 General. Material before being laid off or worked must be straight. If straightening is necessary, it shall be done by methods that will not injure the metal. Sharp kinks or bends shall be cause for rejections of the material. Material with welds will not be accepted, except where otherwise approved. Where heating is required, precautions shall be taken to avoid overheating the metal and it shall be allowed to cool in such a manner as not to destroy the original properties of the metal. Finished members shall be free from twists, bends and open joints.

9.2.2 Finished Surfaces - Where surface finishes are indicated on the drawings or specified herein, the symbols used or finishes specified shall be in accordance with ANSI B46.1-2002. Finished surfaces shall be 125 micro inch unless otherwise shown.
9.3 Protection of Painted and Machined Surfaces: Painted and Machined Surfaces shall be packed so that the items do not contact each other or any other hard surfaces that would cause damage to the painted or machined surfaces.
10: WELDING:
10.1 General: Welding of structural steel shall be by an electric arc welding process using a method which excludes the atmosphere from the molten metal. Welding shall conform to the applicable provisions of AWS D1.1 unless otherwise specified or authorized.
10.2 Welding Procedures. The Contractor shall prepare and submit for approval a complete schedule of Welding Procedure Specifications (WPS) consisting of detailed procedure specifications for each structure to be welded with tables or diagrams showing the procedure to be used for each required joint. The schedule shall conform to the provisions of AWS D1.1. Filler metal, preheat, interpass temperature, and stress relief heat treatment requirements must be included in the procedures. Gas Metal Arc Welding Spray Transfer (GMAW-S) shall not be used.
10.3 Qualification of Welders and Welding Operators. Welding operators, welders, and tack welders shall be qualified and re-qualified if necessary for the particular type of work to be done. Qualification shall be in accordance with AWS D1.1. The Contractor shall provide by name the welders and welding operators qualified, the date of qualification, code and procedures under which qualified. Prior qualification will be accepted if welders have performed satisfactory work under the code for which qualified within the preceding six months. The Contractor shall require welders and welding operators to repeat the qualifying tests when, in the opinion of the Technical Representative, their work indicates a reasonable doubt as to proficiency. Those passing the re-qualification tests shall be re-qualified. Those not passing shall be disqualified until passing. All expenses in connection with qualification and re¬qualification shall be borne by the Contractor.
10.4 Weld Inspections. All welds shall be visually inspected in conformance to AWS D1.1 Structural Welding Code. The Inspector must be a AWS Certified Welding Inspector (CWI) or meet the Inspector Qualification Requirements per AWS D1.1 Structural Welding Code. 20% of all fillet welds shall be MT (magnetic particle testing) inspected per the AWS D1.1. All complete joint penetration welds groove welds shall 100% be UT (ultrasonic testing) inspected per AWS D1.1. All groove welds shown on the drawings with no weld size are complete joint penetration welds. All partial joint penetration welds shall be inspected by MT (magnetic particle testing) in the following manner. Partial joint penetration welds of ½" effective weld size and less shall have 100% of the root pass inspected by MT followed by 100% of the face inspected by MT & VT. Partial joint penetration welds of greater than ½" effective weld size shall have 100% of the root pass inspected by MT, 100% of the weld layer at which the groove depth is ½ filled, and 100% of the face inspected by MT & VT.
11.0 Painting:
11.1. General: Surfaces of ferrous metal work except machined surfaces, shall be given three coats of paint as specified in the drawings. The finished coatings shall be free from holidays, pinholes, bubbles, runs, drops, ridges, waves, laps, excessive or unsightly brush marks, and variations in color, texture, and gloss. Application of initial or subsequent coatings shall not be applied unless the atmospheric conditions and the surfaces to be coated are satisfactory. Each paint coat shall be applied in a manner that will produce an even, continuous film of uniform thickness. Edges, corners, crevices, seams, joints, welds, rivets, corrosion pits, and other surface irregularities shall receive special attention to ensure that they receive an adequate thickness of paint.
11.2. Surface Preparation. Ferrous surfaces shall be dry blast-cleaned to SSPC-SP-7. The blast profile, unless otherwise specified, shall be 1.5 to 2.5 mils as measured by ASTM D 4417, Method C. Appropriate abrasive blast media shall be used to produce the desired surface profile and to give an angular anchor tooth pattern. If recycled blast media is used, an appropriate particle size distribution shall be maintained so that the specified profile is consistently obtained. Steel shot or other abrasives that do not produce an angular profile shall not be used. Weld spatter not dislodged by blasting shall be removed with impact or grinding tools and the areas re-blasted prior to painting. Surfaces shall be dry at the time of blasting.
11.3. Surface Cleaning. All loose scale, rust, dirt, oil, residual traces of abrasive, or other foreign substances must be blown, swept, or vacuumed from the surface prior to prime coating. Oil and grease shall be removed in accordance with SSPC-SP-1, prior to blast cleaning and shall be accomplished with mineral spirits or other low toxicity solvents having a flash point above 100 degrees F.
11.4. Surface Application. Within 8 hours after cleaning, prior to the deposition of any detectable moisture, contaminants, or corrosion, all ferrous surfaces shall be given their first coats of primer. The paint shall be spray applied, except that areas inaccessible to spraying shall be brushed. The paint should be mixed and applied according to the manufacturers "best practices" recommendations. The paint should be well mixed and stirred while being applied and no paint shall be used after it has caked or hardened. Paint shall not be applied to damp surfaces nor when the temperature is below 50 degrees F. Rivets, bolts, and similar surface projections shall receive sprayed paint from every direction to ensure complete coverage of all faces. Pits, cracks, and crevices shall be filled with paint insofar as practicable, but in any event, all pit surfaces shall be thoroughly covered and all cracks and crevices shall be sealed off against the entrance of moisture. Fluid and atomization pressures shall be kept as low as practicable consistent with good spraying results. Except where otherwise indicated, and under coat of the paint may receive the next coat any time after the undercoat is tack free and firm to the touch, provided that no speedup or delay in the re-coating schedule shall cause film defects such as sags, runs, air bubbles, air craters, or poor coat to coat adhesion. Neither the prime coat nor any other coat shall be subjected to any abrading action until it has hardened sufficiently to resist mechanical damage.
