GENERAL NOTES

GRADE BOTTOMS OF TRENCH TO PROVIDE UNIFORM BEARING AND SUPPORT FOR THE BOTTOM

QUADRANT OF EACH SECTION OF THE PIPE. EXCAVATE BELL HOLES TO THE NECESSARY SIZE AT

EACH JOINT TO ELIMINATE POINT BEARING. REMOVE ALL STONES 75mm (3 INCHES) IN DIAMETER

OR GREATER.

WHERE UNSTABLE MATERIAL IS ENCOUNTERED IN THE BOTTOM OF THE TRENCH, REMOVE THE

UNSATISFACTORY MATERIAL A MINIMUM OF 150m (6 INCHES) OR UNTIL SATISFACTORY BEARING

MATERIAL IS ENCOUNTERED AND BRING THE EXCAVATION TO GRADE USING GRANULAR BACKFILL.

PROVIDE BEDDING MATERIAL MEETING THE REQUIREMENTS OF OMA SPECIFICATIONS . PLACE

INITIAL BACKFILL MATERIAL AND COMPACT IT WITH APPROVED TAMPER TO A HEIGHT OF AT LEAST

300mm (12 INCHES) ABOVE THE UTILITY PIPE. BRING UP THE BACKFILL EVENLY ON BOTH SIDES OF

THE PIPE FOR THE FULL LENGTH OF THE PIPE. TAKE CARE TO INSURE THOROUGH COMPACTION

OF THE FILL UNDER THE HAUNCHES OF THE PIPE.

FILL THE REMAINDER OF THE TRENCH WITH OFFSITE SATISFACTORY MATERIAL AND COMPACT TO

95% STANDARD PROCTOR DENSITY.

AFTER THE DROP INLET MANHOLE HAS BEEN CONSTRUCTED AND THE CONCRETE HAS BEEN

ALLOWED TO CURE FOR A MINIMUM OF SEVEN DAYS PLACE BACKFILL SUCH THAT DAMAGE DOES

NOT OCCUR DUE TO THE SHOCK OF THE FALLING SOIL. DEPOSIT BACKFILL MATERIAL EVENLY ON

ALL SIDES AND COMPACT TO 95% STANDARD PROCTOR DENSITY IN 300mm LIFTS.
