1 All surfaces of the port hole rim itself as well as all exterior structural steel areas affected by welding, including weld <br />metal, shall be galvanized in accordance with ASTM A780. <br />2. The following criteria are required for adherence to this standard. <br />A. Use rim as template for cutting hole in monopole. Care shall be taken to minimize the root opening (AWS tolerances <br />allow a maximum of 0. 19"). <br />B. Provide minimum 24" clear vertical separation between rim and other openings in monopole. Align ports on same <br />azimuth as existing ports. <br />C. Maximum variance of port hole center elevation shall not be greater than 6 <br />D. Provide 90' minimum radial separation or two times the hole width clear circumferential separation between rim and <br />adjacent opening in monopole, whichever is greatest. 18-sided pole with 4 ports shall not be allowed. <br />E. Edge of opening for the exit port must be at least 24" from splice. <br />I I <br />F. Grind all edges of cut opening, achieving a bevel angle of 450 and removing the zinc from the weld area plus 1/4 <br />Ensure all weld areas and surfaces are clean and free of zinc and loose particles. Zinc shall not be allowed to <br />contaminate the weld. <br />G. Position the rim as required and securely tack weld. Finish welding the rim with bevel weld and reinforcing fillet weld <br />size as determined from the design method. <br />6. All proposed and/or replaced <br />bolts shall <br />be of sufficient length such that the <br />end of the bolt <br />be at least flush with the face <br />of the nut. it <br />is not permitted <br />for the <br />bolt <br />end to <br />be <br />below <br />the <br />face of <br />the <br />nut <br />after tightening <br />is completed. <br />7. Hot -dip galvanize all items, UNO. <br />Galvanize per ASTM Al 23, ASTM Al 53/A1 53M or ASTM A653 G90, as applicable. <br />8.
