STRUCTURAL NOTES
1. DIMENSIONS FROM FACE OF CONCRETE TO STEEL ARE
TO CENTER OF BAR, UNLESS OTHERWISE SHOWN.
2. CONCRETE DIMENSIONS SHALL BE MEASURED
HORIZONTALLY OR VERTICALLY ON THE PROFILE, AND
PARALLEL TO OR AT RIGHT ANGLES (OR RADIALLY)
TO CENTER LINE OF CONDUIT ON THE PLAN EXCEPT AS
OTHERWISE SHOWN.
3. ALL BAR BENDS AND HOOKS SHALL CONFORM TO THE
AMERICAN CONCRETE INSTITUTE'S "BUILDING CODE
REQUIREMENT FOR REINFORCED CONCRETE", LATEST
EDITION, SECTIONS 7.1 AND 7.2.
4. TRANSVERSE CONSTRUCTION JOINTS SHALL NOT BE
PLACED WITHIN 30 INCHES OF MANHOLE OR JUNCTION
STRUCTURE OPENINGS.
5. TRANSVERSE CONSTRUCTION JOINTS IN WALLS AND
SLABS SHALL BE IN THE SAME PLANE. NO
STAGGERING OF JOINTS WILL BE PERMITTED.
TRANSVERSE CONSTRUCTION JOINTS SHALL BE NORMAL
OR RADIAL TO THE CENTER LINE OF CONSTRUCTION.
6. THE TRANSVERSE REINFORCING BARS SHALL TERMINATE
ONE AND ONE-HALF INCHES FROM THE CONCRETE
SURFACES UNLESS OTHERWISE SHOWN ON THE
STRUCTURAL DETAILS.
7. EXPOSED EDGES OF CONCRETE MEMBERS SHALL BE
ROUNDED OR BEVELED.
8. NO SPLICES IN TRANSVERSE BARS REINFORCEMENT
WILL BE PERMITTED OTHER THAN SHOWN ON THE
DRAWING WITHOUT APPROVAL OF THE ENGINEER. NO
MORE THAN TWO SPLICES WILL BE PERMITTED IN ANY
LONGITUDINAL BAR BETWEEN TRANSVERSE JOINTS.
SPLICES SHALL BE STAGGERED.
9. LONGITUDINAL BARS SHALL BE LAPPED 20 BAR
DIAMETERS AT SPLICES. TRANSVERSE BARS SHALL
BE LAPPED 30 BAR DIAMETERS AT SPLICES.
10. LONGITUDINAL BARS SHALL BE CONTINUOUS AND
EXTEND THROUGH ALL CONSTRUCTION JOINTS.
11. UNLESS OTHERWISE SHOWN ON THE DRAWINGS,
TRANSVERSE CONSTRUCTION JOINTS (IN BOTH SLABS
AND WALLS), SHALL BE PLACED AT THE END OF EACH
POUR, BUT THE SPACING THEREOF SHALL NOT EXCEED
50 FEET NOR BE LESS THAN 10 FEET.
12. UNLESS OTHERWISE SHOWN ON THE DETAILS, IN
CURVED SECTIONS TRANSVERSE BARS SHALL BE PLACED
RADIALLY. STRAIGHT TRANSVERSE BARS IN TOP AND
BOTTOM SLABS SHALL BE SPACED AS SHOWN ON THE
TYPICAL SECTIONS: SPACING SHALL BE AT THE
CENTER LINE OF THE BARREL ON THE OUTSIDE OF THE
CURVE FOR DOUBLE BARREL BOXES. STRAIGHT BARS
AND L -BARS IN WALLS SHALL BE SPACED AS SHOWN
ON THE TYPICAL SECTIONS, WITH THE SPACING
MEASURED BETWEEN THE VERTICAL LEGS OF BARS.
13. AT THE BEGINNING AND ENDING OF ALL POURS, A
CURTAIN OF REINFORCEMENT COMPOSED OF B, C,
C2, D, CW, F, G, AND H BARS SHALL BE PLACED
THREE INCHES FROM THE TRANSVERSE CONSTRUCTION
JOINT.
14. D BARS AND CW BARS MAY BE SPLICED 20 BAR DIAMETERS
AT THE LOWER LONGITUDINAL CONSTRUCTION JOINT,
AT CONTRACTOR'S OPTION.
15. IN ALL SECTIONS LAP C AND C2 BARS. THE
VERTICAL LENGTH OF C AND C2 BARS HAS BEEN
CALCULATED FOR A FOUR -INCH STARTER WALL. IF
THE HEIGHT OF THE STARTER WALL IS VARIED,
THE VERTICAL LENGTH OF THE C AND C2 BARS SHALL
BE VARIED CORRESPONDINGLY SO AS TO MAINTAIN A
30 DIAMETER LAP BETWEEN THE TWO BARS. THE
LAPS SHALL BE BASED ON THE SMALLER BARS.
16. CONCRETE QUANTITIES ARE BASED ON A SIX -BY -SIX
INCH FILLET AND THE STEEL QUANTITIES DO NOT
INCLUDE ANY OPTIONAL SPLICES.
17. IF WALL THICKNESS IS SIX INCHES, PLACE
REINFORCEMENT AT THE CENTER LINE OF THE WALL.
18. THE DESIGN OF BOX SECTIONS IDENTIFIED BY A
NUMERICAL VALUE ONLY IS BASED ON A WIDTH OF
TRENCH EQUAL TO THE OUTSIDE WIDTH OF THE
CONDUIT PLUS 3 FEET. WHEN THE COVER IS EQUAL
TO 10 FEET OR LESS THE TRENCH WIDTH IS
UNRESTRICTED. WHEN THE COVER IS GREATER THAN
10 FEET AND THE TRENCH WIDTH IS GREATER THAN
THE OUTSIDE WIDTH OF THE CONDUIT PLUS 3 FEET
FOR A DISTANCE IN EXCESS OF 10 FEET AN
ALTERNATE SECTION SHALL BE USED AS INDICATED
BELOW:
A. WHEN THE DEPTH OF COVER IS LESS THAN 18
FEET, SECTIONS WITH THE SUFFIX "B" SHALL
BE USED.
B. WHEN THE DEPTH OF COVER IS GREATER THAN 18
FEET AND:
1. THE TRENCH WIDTH IS LESS THAN THE
OUTSIDE WIDTH OF THE CONDUIT PLUS 6
FEET, SECTIONS WITH THE SUFFIX "A"
SHALL BE USED.
2. THE TRENCH WIDTH IS GREATER THAN THE
OUTSIDE WIDTH OF CONDUIT PLUS 6 FEET,
SECTIONS WITH THE SUFFIX "B" SHALL BE
USED.
