After the above test, the weld section shall not <br />exhibit any tearing out or cracking. <br />B. Types of Welds (unless otherwise noted): <br />1. Make all fillet welds 3/16 inch minimum. <br />2. Make all butt welds complete penetration welds, see Article 3.03 A. <br />3. Welds not required to be complete penetration welds are specifically noted on the <br />Drawings. <br />C. Grinding: Grind smooth the following structural steel and connections; <br />1. Exposed cut ends of structural and fabricated shapes. <br />2. All welds exposed to view. <br />3. Mitered and fit -up corners and intersections. <br />D. Backing Bars: Required for all complete penetration welds <br />3.04 ERECTION <br />A. General: Erect all structural steel in strict accordance with the Drawings, and all pertinent <br />regulations, unless otherwise noted. <br />B. Erection Tolerances: <br />General: Per AISC Code of Standard Practice: <br />a. Maximum Variation from Plumb: 1/4 inch per story, non -cumulative, <br />b. Maximum Offset from True Alignment: 1/4 inch. <br />2. Acceptance of Position and Alignment: Prior to placing or applying any other materials, <br />the Contractor is responsible for determining that the location of the structural steel is <br />acceptable for plumbness, level and alignment within tolerances. The erector is given <br />timely notice of acceptance by the Contractor or a listing of specific items to be <br />corrected in order to obtain acceptance. Such notice is rendered immediately upon <br />completion of work and prior to start of work by other trades that may be supported, <br />attached to the structural steelwork. <br />C Templates: Provide bolt setting templates for all anchor bolts. Provide instructions for the <br />setting of anchors and bearing plates, verify these items are set correctly as work <br />progresses. <br />D. Column base plates: Set level to correct elevations, support temporarily on steel wedges, <br />shims, or leveling nuts where shown, until the supported members are plumbed and grouted. <br />1. Grout solid the full bearing area under base plates prior to installation of floor and/or <br />roof decks. See Section 03300 - Cast -In -Place Concrete. <br />2.
