KOR Review Guidelines – Structural Steel

STANDARD NOTES AND DETAILS – THINGS TO CHECK:

  1. CHECK THAT EVERY MEMBER SHOWN ON THE STRUCTUREAL DRAWINGS IS IN PLACE AND IN THE CORRECT CONFIGURATION.
  2. CHECK MEMBERS AS FOLLOWS:
    1. VISUALLY CHECK ALL BEAM DEPTHS AND COLUMN DIMENSIONS AND SPOT CHECK WITH A TAPE MEASURE.
    2. SPOT CHECK MEMBER FLANGE WIDTHS AND/OR THICKNESS AGAINST THE STEEL HANDBOOK.
    3. VISUALLY CHECK IF MEMBERS ARE GLVANIZED OR SPECIALLY PRIMED IF SO REQUIRED BY DRAWINGS.
    4. GENERALLY CHECK FOR MISALIGNED OR OUT-OF-PLUMB MEMBERS, FIELD MODIFICATIONS, AND CUTTING OF MEMBERS BY OTHER TRADES.
  3. CHECK CONNECTIIONS AS FOLLOWS:
    1. CHECK THAT ALL BOLTS ARE IN PLACE.
    2. SPOT CHECK A FEW BOLTS BY HAND TO SEE IF THEY HAVE BEEN TIGHTENED.
    3. CHECK THAT BOLT HOLES HAVE NOT BEEN ENLARGED BY GAS-CUTTING.
    4. CHECK FOR A “FULL” NUT ON EACH BOLT.
    5. CHECK THAT ALL WELDED CONNECTIOINS HAVE BEEN WELDED IN SOME MANNER. EXAMINE A FEW WELDS CLOSER TO GET A GENERAL IMPRESSION OF THE QUALITY OF THE WELDING.
    6. CHECK BEARING LENGTHS.
      FULLY CHECK ALL CONNECTIONS WHICH ARE FULLY DETAILED ON THE STRUCTUREAL DRAWINGS.
    7. IF A CONNECTION SEEMS LIGHT FOR THE SIZE OF THE CONNECTED MEMBERS, CHECK THE SHOP DRAWINGS TO SEE IF IT CORRECT.
    8. IF A CONNECTION IS OF A DIFFERENT FORM THAN SHOWN ON THE STRUCTUREAL DARWINGS (I.E. SINGLE-ANGLE INSTEAD OF DOUBLE-ANGLE), CHECK THE SHOP DRAWINGS TO SEE IF THE CHANGE HAS BEEN APPROVED BY THE DESIGN ENGINEER.
    9. IF A CONNECTION HAS BEEN SIGNIFICANTLY ALTERED TO MAKE IT FIT, AND THE ALTERATION SEEMS INADEQUATE TO THE DESIGN ENGINEER, THE SPECIALTY STRUCTUREAL ENGINEER SHOULD BE ASKED TO PROVIDE A SEALED LETTER OR SKETCH ATTESTING TO ITS ADEQUACY.
    10. IF A MEMBER HAS BEEN (WELD) SPLICED BETWEEN CONNECTIONS, AND THE SPLICE IS IN A CRITICAL LOCATION (I.E. NEAR MIDSPAN), IT SHOULD BE TESTED TO THE CONTRACTOR’S ACCOUNT.
      CHECK THAT COMPLETE CONNECTION ARE TOUCHED UP WITH PRIMER (AND PAINT) AS REQUIRED.
  4. CHECK OPEN-WEB STEEL JOISTS AS FOLLOWS:
    1. VISUALLY CHECK DEPTHS (SPOT CHECK WITH A TAPE MEASURE).
    2. COUNT THE NUMBER OF JOISTS OR VISUALLY CHECK SPACINGS.
    3. EXAMINE A FEW JOISTS TO GET A GENERAL IMPRESSION OF THE QUALITY OF THE WELDING BETWEEN CHORDS AND DIAGONALS, AND THE WELDING OF THE JOIST ENDS TO THE SUPPORTING MEMBERS.
    4. CHECK JOIST BEARING AND ECCENTRICITY (DISTANCE FROM FACE OF SUPPORT TO FIRST DIAGONAL) AT SUPPORTS. REPORT ANYTHING UNUSUAL TO DESIGN ENGINEER.
    5. IF THE STRUCTUREAL DRAWINGS SHOW THE BRIDGING LOCATIONS AND ARRANGEMENT, VISUALLY CHECK THAT THIS HAS BEEN FOLLOWED. OTHERWISE, JUST VISUALLY CHECK THAT BRIDGING OF SOME SORT IS IN PLACE.
    6. CHECK FOR BOTTOM CHORD EXTENSIONS AT SUPPORTS, WHERE REQUIRED BY THE STRUCTUREAL DRAWINGS.
  5. CHECK STEEL DECK AS FOLLOWS:
    1. CHECK GAUGE, DEPTH.
    2. CHECK NUMBER (OR SPACING) OF PUDDLE WELDS AND BUTTON PUNCHING.
    3. EXAMINE A FEW PUDDLE WELDS TO GET A GENERAL IMPRESSION OF THE QUALITY.
    4. CHECK STEEL DECK FROM BELOW TO SEE IF PUDDLE WELDS HAVE BEEN MISSED JOIST CHORDS (OR BEAMS) OR BURNED THROUGH.
    5. CHECK LONGITUDINAL EDGES OF DECK FOR CORRECT WELDING TO PERIMETER SUPPORTS. OFTEN TH DECK ENDS ON THE HIGH FLUTE INSTEAD OF THE LOW AND HAS TO BE “PATCHED UP”.
    6. VISUALLY CHECK THAT THE SPECIFIED DECK COATING HAS BEEN APPLIED.
    7. CHECK THAT PUDDLE WELDS ARE COATED WITH SHOP PRIMER OR “GALVACON” AS REQUIRED.
    8. CHECK THAT OPENINGS IN STEEL DECK ARE REINFORCED AS PER THE STANDARD NOTES.
