Verify that structural steel may be fabricated and erected in strict accordance with the <br />original design, the approved Shop Drawings, and the referenced standards. <br />B. Discrepancies: <br />1. In the event of discrepancy, immediately notify the Architect. <br />2. Do not proceed with fabrication or installation in areas of discrepancy until all such <br />discrepancies have been fully resolved. <br />3.02 FABRICATION <br />A. General: Fabricate all structural steel in strict accordance with the approved Construction <br />Documents and the referenced standards. <br />B. Holes, Cutouts, and Fittings: <br />1. General: Provide where shown on structural drawings and steel shop drawings. No <br />additional holes, cutouts, or fittings permitted without written permission. <br />2.

Shop cleaning and priming: <br />Finishes: Prepare and finish structural component surfaces as follows: <br />a. Structural and miscellaneous Steel for interior dry exposure (finish painted or <br />unpainted): <br />1.) Surface preparation: SSPC-SP2 hand tool or SP3 Power Tool Cleaning. <br />Where jobsite exposure is expected to exceed 6 months, SSPC-SP6 <br />Commercial Blast Cleaning is required. <br />2.) Apply Primer Type A. <br />b. Structural and miscellaneous exterior steel or interior steel subjected to wet <br />conditions or fumes (finish painted): <br />1.)
