ARE TO BE CONSTRUCTED IN THE SHAPE SHOWN.

2. CONSTRUCTION MAY BE CAST-IN-PLACE, PRECAST IN ONE OR

MORE MULTIPLE SECTIONS, OR ANY COMBINATION OF

CAST-IN-PLACE AND PRECAST.

3. OPTIONAL CONSTRUCTION JOINTS LABELED "CJ" MAY BE

ROUGHENED CONCRETE, KEYED OR DOWELED AS PER THE

TYPICAL DETAILS SHOWN HEREIN, OR AS APPROVED BY THE

ENGINEER. NON SHRINK GROUT MEETING THE REQUIREMENTS

OF SUBSECTION 715.5 OF THE SPECIFICATIONS MAY BE USED TO

A DEPTH OF 1/2" FOR LEVELING BETWEEN PRECAST SECTIONS.

THICKER DEPTHS WILL BE ALLOWED AS PER THE

MANUFACTURER'S RECOMMENDATIONS.

4. THE FINAL INSTALLED TOP SURFACE OF INLET AND GRATE SHALL

BE FLUSH WITH ADJACENT FINISHED SURFACES SUCH AS

PAVEMENT, GUTTERS, CURBS, AND SIDEWALKS. TOP OF GRATE

ELEVATION, IF SHOWN ON THE PLANS, IS FOR INFORMATION

ONLY.

5. REBARS ARE TO BE INSTALLED AT THE QUARTER POINTS TO

CONNECT CURB TO INLET. REBARS ARE NOT REQUIRED IF CURB

IS POURED MONOLITHICALLY WITH THE INLET OR IF TYPE V OR VI

MEDIAN IS SPECIFIED ON THE PLANS.

6. THE CONTRACTOR MAY, AT HIS OPTION, OMIT USE OF THE

SHALLOW FRAME BY FORMING A LEDGE IN THE CONCRETE.

7. SPECIAL CARE SHALL BE EXERCISED IN FORMING THE 2" WIDE

CONCRETE LEDGE TO PROVIDE A SMOOTH, EVEN SURFACE FOR

SUPPORTING THE GRATE IF A FRAME IS NOT USED. NO

PROJECTIONS SHALL EXIST ON THE GRATE AND THE GRATE

SHALL SEAT ON THE LEDGE WITHOUT ROCKING.

8. FIBRE FORM SHALL BE REMOVED PRIOR TO COMPLETION OF THE

PROJECT.

9. PC (MINIMUM PIPE COVER) SHALL BE 12" BELOW INLET TOP FOR

PIPES PLACED UNDER SIDEWALK OR GRASSED AREA OR 24"

BELOW INLET TOP FOR PIPES PLACED UNDER PAVEMENT OR

SHOULDER.

10.CURB, IF SPECIFIED, MAY BE EITHER CONCRETE PLACED ON THE

INLET BACKWALL AS DETAILED HEREIN OR AN APPROVED CURB

BOX AS MANUFACTURED WITH THE GRATE AND FRAME.

DIMENSIONS OF THE CURB BOX SHOULD REASONABLY CONFORM

TO THE STANDARD CURB AS SPECIFIED IN THE PLANS. THE CURB

WILL BE PAID FOR PER SECTION 610, IN EITHER CASE.

11.THIS INLET SHALL NOT BE PLACED IN A PEDESTRIAN CROSS

WALK.

12.THE MINIMUM DISTANCE FROM THE TOP OF ANY PIPE OPENING

TO ANY CONSTRUCTION JOINT ABOVE THE OPENING SHALL BE

FOUR (4) INCHES.

13.THE NUMBER AND LOCATION OF PIPE OPENINGS SHALL BE AS

SHOWN IN THE PLANS. THE CONTRACTOR AT NO ADDITIONAL

COST, SHALL BE RESPONSIBLE FOR ANY TEMPORARY BRACING

1. ALL CONCRETE SHALL BE CLASS B CONCRETE.

2. REINFORCING STEEL SHALL BE NEW BILLET STEEL AND SHALL

CONFORM TO THE REQUIREMENTS OF 709.1 OF THE

SPECIFICATIONS.

3. THE COVERING FOR REINFORCING STEEL SHALL BE 2"

MEASURED FROM THE SURFACE OF THE CONCRETE TO THE

FACE OF THE BAR, UNLESS OTHERWISE NOTED ON THE PLANS.

REINFORCEMENT IN MEMBERS WHERE CONCRETE IS DEPOSITED

ON THE GROUND SHALL HAVE 3" OF CONCRETE FROM THE FACE

OF THE BAR TO THE GROUND CONTACT SURFACE.

4. ALL EXPOSED EDGES SHALL HAVE A 3/4" x 45° CHAMFER.

CHAMFER ON VERTICAL EDGES SHALL BE CONTINUED A MINIMUM

OF ONE FOOT BELOW FINISHED GROUND LINE.

5. WHEN WINGWALLS ARE PLACED ON THE INLET END OF

CORRUGATED METAL OR STRUCTURAL PLATE PIPE, A BEVEL

SHALL BE USED AT THE INLET OPENING. THE END OF THE PIPE

SHALL BE SET IN FROM THE FACE OF THE WALL AS SHOWN ON

THE "BEVEL DETAIL", AND THE BEVEL CONSTRUCTED FROM THE

END OF THE PIPE TO THE FACE OF THE WALL.

6. WHEN WINGWALLS ARE PLACED ON THE INLET END OF

CONCRETE PIPE, THE "BELL" OR "GROOVE" OF THE PIPE SHALL

BE PLACED IN THE WALL, AND THE INSIDE OF THE "BELL" OR

"GROOVE" SHALL BE FILLED WITH CONCRETE UP TO THE FLOW

LINE.

7. BEVELS ARE NOT REQUIRED ON OUTLET WINGWALLS OR ON

INLET WINGWALLS FOR CONCRETE PIPE.

8. KEYED OR DOWELED TYPE CONSTRUCTION JOINTS,

ACCEPTABLE TO THE ENGINEER, MAY BE USED DURING

CONSTRUCTION.

9. IF EMBANKMENT SLOPE ABOVE WINGWALLS IS FLATTER THAN

2:1, PROVIDE WINGS FOR 2:1 SLOPE AND WARP EMBANKMENT TO

2:1 SLOP AT WINGWALL.

10.THE PAY QUANTITY FOR WINGWALLS, CONSTRUCTED IN

ACCORDANCE WITH THE DETAILS HEREIN, WILL BE THE CUBIC

YARDS OF CLASS B CONCRETE SPECIFIED ON THIS SHEET. COST

OF ALL REINFORCING STEEL SHALL BE INCLUDED IN THE UNIT

PRICE BID FOR CLASS B CONCRETE.

11.WATERSTOP MEETING THE REQUIREMENTS OF 708.10 SHALL BE

PLACED AS SHOWN WHEN CONCRETE GUTTER IS TO ABUT THE

WINGWALL.
