NOTES:

1. THIS DETAIL APPLIES FOR OPENINGS 8"∅ AND LARGER. FOR SMALLER

OPENINGS, BEND BARS OR ADJUST SPACING OF REINFORCEMENT TO

AVOID OPENING.

2. PLACE EXTRA BARS OF THE SAME SIZE AS THE INTERRUPTED BARS AT

EACH SIDE OF OPENING. QUANTITY OF EXTRA BARS AT EACH SIDE

SHALL EQUAL HALF THE QUANTITY OF INTERRUPTED BARS EXCEPT

WHERE NOTED OTHERWISE.

3. PROVIDE ONE DIAGONAL BAR EACH SIDE OF OPENING WITH SIZE EQUAL

TO MAIN REINFORCEMENT, TYPICAL EACH FACE.

4. WHERE INVERT OF OPENING IN WALL IS LESS THAN 44 BAR DIAMETERS

FROM TOP OF SLAB, EXTRA REINFORCEMENT ON EACH SIDE SHALL

INCLUDE DOWELS EMBEDDED INTO SLAB WITH STANDARD 90 DEGREE

HOOKS TO SPLICE WITH EXTRA VERTICAL REINFORCEMENT. DOWELS

SHALL ALSO STILL BE PROVIDED BELOW OPENING.

5. WHERE INVERT OF OPENING IN WALL OR SLAB IS CLOSER THAN 44 BAR

DIAMETERS TO EDGE OF SLAB OR BOTTOM OF WALL, EXTRA DIAGONAL

BARS MAY BE TERMINATED TWO INCHES FROM EDGE OF SLAB OR

BOTTOM OF WALL. DOWELS DO NOT HAVE TO BE PROVIDED TO SPLICE

WITH DIAGONAL BARS.

FLOOR SLAB.

2. THE CONTRACTOR SHALL PROVIDE LEVELING CHANNELS AND LEVELING CHANNEL ANCHORS FOR

SWITCHGEAR, SWITCHBOARDS, MOTOR CONTROL CENTERS, AND SIMILAR EQUIPMENT WHEN

REQUIRED TO MEET EQUIPMENT MANUFACTURER'S LEVELING TOLERANCES. THE CONTRACTOR SHALL PROVIDE 1" MINIMUM NON-SHRINK GROUT FOR PUMPS AND SIMILAR EQUIPMENT WHEN REQUIRED TO

MEET EQUIPMENT MANUFACTURER'S UNIFORM BEARING AND LEVELING REQUIREMENTS.

3. PRIOR TO PLACING CONCRETE PAD, LEVELING CHANNEL SIZE AND MEANS OF INSTALLATION, ANCHORAGE, GROUT, CONCRETE EDGE DISTANCE, AND CONCRETE BLOCKOUTS REQUIREMENTS

SHALL BE COORDINATED WITH EQUIPMENT MANUFACTURER.

4. COAT DISSIMILAR MATERIALS PER THE CONTRACT DOCUMENTS.

5. STAGGER CHANNEL ANCHORS AND PAD DOWELS.

6. FOR PADS 24" OR GREATER IN DEPTH, PROVIDE #4@8" HORIZONTAL SKIN REINFORCING AROUND

PERIMETER OF PAD.
