NOTES:
1. SEE PLANS FOR NUMBER OF CONDUITS TO BE PROVIDED WHERE DUCTS ARE UNDER
FULL STRENGTH PAVEMENT. WHERE TWO OR MORE CONDUITS ARE INSTALLED IN ONE
TRENCH, PROVIDE PLASTIC CONDUIT SPACERS AT 5' OC LONGITUDINALLY TO ENSURE
UNIFORM SPACING BETWEEN CONDUITS. ENSURE SPACERS ARE SECURED IN TRENCH
TO PREVENT MISALIGNMENT. CONDUITS MAY BE SPACED VERTICALLY OR HORIZONTALLY.
SPACING BETWEEN CONDUITS SHALL BE 3" MINIMUM WITH A 3" THICKNESS OF CONCRETE
SURROUNDING THE GROUP OF CONDUITS AS SHOWN. PROVIDE MINIMUM CONDUIT SLOPE
OF 0.5 PERCENT WHERE POSSIBLE.
2. ENSURE COUPLINGS OF ADJACENT CONDUITS ARE STAGGERED A MINIMUM OF 12" APART
FOR CONDUITS 2" DIAMETER OR SMALLER AND 24" APART FOR CONDUITS LARGER THAN
2" DIAMETER.
3. ENSURE ALL EMPTY DUCTS OVER 15' IN LENGTH ARE PROVIDED WITH A 200 LB. TENSILE
STRENGTH POLYPROPYLENE PULL ROPE.
4. CONDUITS MAY BE PLACED IN A SINGLE LAYER WHEN NECESSARY TO MEET VERTICAL
CLEARANCES.
