1.  Too close to free edge.  Based on hole position, consider effect on splice capacity if the bolt were ignored and investigate how close the hole is to the edge.  “As is” condition may be satisfactory.  If unsure, evaluate pattern and any holes not yet drilled to see if spacing and edge distance on other holes permit “as is”.  The last resort is to increase web splice plate size and add a row of bolts.

2.   Hole too close to edge of splice plate.  Investigate possibility of planing edge.  Consider enlarging splice depth if clearance permits. See above alternates if planing and/or enlarging splice depth is unsatisfactory.

3.    Hole too close to adjacent hole.  Consider parameters in AISC’s “Specification for Structural Joints Using ASTM A325 or A490 bolts” to determine if bolts’ installation requirements and contact areas justify using “as is”.  See alternates above (1 & 2) otherwise.
