PART 2 EXECUTION

2.1 PREPARATION OF MATERIAL

A. To minimize warpage and distortion, fabrication shall be per ASTM A384. B. Cold-worked material shall be handled per ASTM A143 to safeguard against embrittlement. C. A stamped metal tag shall be wired to all fabricated structural steel, pipe, etc., before

galvanizing to assure identification after galvanizing. D. All structural steel, pipe, etc., shall be thoroughly cleaned by the fabricator after fabrication

and before galvanizing. This cleaning shall include removal of all weld splatter, slag and flux deposit.

E. All mill scale, rust, oil and other foreign matter shall be removed by the galvanizer before



galvanizing.

2.2 GALVANIZING

A. Material shall be hot-dip galvanized as follows, unless otherwise specified on the drawings: 1. Structural steel shapes, plates, pipe, grating and bars per ASTM A123, and/or A120. 2. Hardware, bolts, nuts, etc., per ASTM A153. 3. Each component shall be completely submerged in the molten zinc. If multi-dipping is

necessary for complete coverage, a procedure which gives the minimum amount of warping shall be used.

4. Components of bolted assemblies shall be dipped separately with bolts removed. 5. Each component shall be brushed or wiped after dipping to remove flux, icicles, dross

or any irregularity in the zinc coating. 6. Components shall be checked for straightness after dipping and shall be straightened if

warped. Permissible variations in cross section, flatness, and straightness of components shall be per ASTM A6 except that the tolerances permitted for 3-inch structural shapes also apply to sizes 1 1/2 inches to 3 inches.

7. After galvanizing, internal threads in nuts and tapped holes shall be retapped oversize as follows when the external threads on the bolts or matching member are to be galvanized.

OVERSIZE OF INTERNAL THREAD

BOLT DIAMETER DIAMETER INCHES

Under 5/8” 1/64 5/8” and Over 1/32

2.3 USING COLD GALVANIZING COMPOUND

A. Preparation of the damaged surface is critical. The following general guidelines shall apply:

1. Surfaces to be reconditioned with cold galvanizing compound shall be clean, dry, and free of oil, grease, and corrosion products.

2. Blast clean the surface to near-white metal, in accordance with SSPC-SP10 (1 to 2 mil (25 to 50 um) anchor pattern), as a minimum. Where circumstances do not allow blast cleaning, it is permissible to power disk sand areas to be repaired to bright metal. To ensure that a smooth reconditioned coating can be effected, surface preparation shall extend into the undamaged galvanized coating. The method and extent of surface preparation shall be determined by the Engineer.

3. If the area to be reconditioned includes welds, first remove all flux residue and weld spatter of a size or type that cannot be removed by blast cleaning by mechanical means, that is, chipping, etc.

4. Brush-apply the cold galvanizing compound to the prepared area. Apply the compound as recommended by the manufacturer employing multiple passes to achieve a dry film thickness as specified in Section 05100, paragraph 3.01(B).

5. Take thickness measurements with either a magnetic or electromagnetic gage to ensure that the applied coating thickness is as specified.

2.4 QUALITY ASSURANCE AND QUALITY CONTROL

A. The adherence of the zinc coating to the surface of the base metal shall be determined by

cutting or prying with the point of a heavy knife, applied with sufficient pressure to remove a portion of the coating. The adherence shall be considered inadequate if the coating flakes off in the form of a layer of skin so as to expose the base metal in advance of the knife point. Testing carried out at edges or corners (points of lowest coating adherence) shall not be used to determine adherence of coating. Likewise, removal of small particles of the coating by paring or whittling shall not be used to determine failures.



B. The distribution of the zinc coating shall be determined by visual inspection. Except for local excess coating thickness, which would interfere with the use of the product, rejection for poor distribution shall be made only for plainly visible excess coating not related to design factors such as holes, joints, or special drainage problems. If, in the opinion of the examiner, visual examination is not conclusive, the distribution of zinc can be determined by the use of a magnetic thickness gauge after a sufficient number of readings (not less than 10), is taken at each end and in the middle of the piece being examined.

C. The average weight of coating shall be determined by magnetic thickness gauge where its use is applicable. Where thickness measurement is not feasible, the coating weight shall be determined as specified in Table I (ASTM specifications).

hickey or conduit-bending machine. Do not install crushed or deformed conduits. Avoid trapped conduits. Prevent plaster, dirt, or trash from lodging in conduits, boxes, fittings, and equipment during construction. Free clogged conduits of obstructions.

4. Pull Wire: Install pull wires in empty conduits. Pull wire shall be plastic having minimum 200 pound tensile strength. Leave minimum 36 inches of slack at each end of pull wire.

5. Locknuts and Bushings: Fasten conduits to sheet metal boxes and cabinets with two locknuts where required by NFPA 70, where insulated bushings are used, and where bushings cannot be brought into firm contact with the box; otherwise, use at least minimum single locknut and bushing. Locknuts shall have sharp edges for digging into wall of metal enclosures. Install bushings on ends of conduits, and provide insulating type where required by NFPA 70.

6. Flexible Connections: Provide flexible steel conduit between 3 and 6 feet in length for equipment subject to vibration, noise transmission, or movement; and for motors. Install flexible conduit to allow 20 percent slack. Minimum flexible steel conduit size shall be 1/2 inch diameter. Provide liquidtight flexible conduit in wet and damp locations and for equipment subject to vibration, noise transmission, movement or motors. Provide separate ground conductor across flexible connections.

C. BOXES, OUTLETS, AND SUPPORTS

1. Provide boxes in wiring and raceway systems wherever required for pulling of wires, making connections, and mounting of devices or fixtures. Boxes for metallic raceways shall be cast-metal, hub-type when located in wet locations, when surface mounted on outside of exterior surfaces and when specifically indicated. Boxes in other locations shall be sheet steel, except that aluminum boxes may be used with aluminum conduit, and nonmetallic boxes may be used with nonmetallic conduit system. Each box shall have volume required by NFPA 70 for number of conductors enclosed in box. Provide gaskets for cast-metal boxes installed in wet locations and boxes installed flush with outside of exterior surfaces. Fasten boxes and supports with wood screws on wood, with bolts and expansion shields on concrete or brick, with toggle bolts on hollow masonry units, and with machine screws or welded studs on steel. When penetrating reinforced concrete members, avoid cutting reinforcing steel.

2. Boxes for use with raceway systems shall be minimum 1 1/2 inches deep, except where shallower boxes required by structural conditions are approved.

3. Pull Boxes: Construct of at least minimum size required by NFPA 70 of code-gauge aluminum or galvanized sheet steel, except where cast-metal boxes are required in locations specified herein. Provide boxes with screw-fastened covers.

4. Conductor Identification: Provide conductor identification within each enclosure where tap, splice, or termination is made. For conductors No. 6 AWG and smaller

Page 6 of 7

diameter, color coding shall be by factory-applied, color-impregnated insulation. For conductors No. 4 AWG and larger diameter, color coding shall be by plastic-coated, self-sticking markers; colored nylon cable ties and plates; or heat shrink-type sleeves.

5. Splices: Make splices in accessible locations. Make splices in conductors No. 10 AWG and smaller diameter with insulated, pressure-type connector. Make splices in conductors No. 8 AWG and larger diameter with solderless connector, and cover with insulation material equivalent to conductor insulation.

6. Covers and Device Plates: Install with edges in continuous contact with finished wall surfaces without use of mats or similar devices. Plaster fillings are not permitted. Install plates with alignment tolerance of /16 inch. Use of sectional-type device plates are not permitted. Provide gasket for plates installed in wet locations.

7. Grounding and Bonding: In accordance with NFPA 70. Ground exposed, non-current-carrying metallic parts of electrical equipment, metallic raceway systems, grounding conductor in metallic and nonmetallic raceway systems.

8. Equipment Connections: Provide power wiring for the connection of motors and control equipment under this section of the specification.
