(b)Anchor Bolts, Nuts, and Washers. Section 1105.02(c)2, galvanized as specified in Section 1105.02(s).

(c)Caulking Compound. Section 705. 7

1012.3CONSTRUCTION —As shown on the Standard Drawings and as follows:

(a)General. Before erection, thoroughly coat the surface of aluminum alloys in contact with other metals,

stone masonry, or concrete with caulking compound. After erection and alignment, seal openings between metal surfaces and concrete with caulking compound. After the concreting and other operations have been completed, thoroughly clean the railing. Remove accumulations of oil, grease, dirt, or foreign materials, using a solvent cleaner.

(b)Assembly. Assemble, as shown on the accepted shop drawings and the Standard Drawings .

Make cuts true, smooth, and free from burrs or ragged edges. Fillet -drill all re -entrant cuts, before cutting. Do not flame cut. To facilitate bending, Contractor may heat material to a temperature of 400F for a period not exceeding 15 minutes. Drill rivet and bolt holes, or subpunch 3/16 inc
