GENERAL NOTES:
1. FOUNDATION SHALL BE CLASS "A" CEMENT CONCRETE MASONY.
2. REINFORCEMENT SHALL BE A.S.T.M. A615- GR.60.
3. BOLT CIRCLE AND ANCHOR BOLTS TO BE PROVIDED BY THE CONTRACTOR.THE ANCHOR
BOLTS SHALL BE SUPPLIED WITH A TEMPLATE FOR SETTING THE BOLTS AND NECESSARY
BOLT PROJECTIONS.
4. PROVIDE FOR ELECTRICAL CONDUIT AS REQUIRED:
5. EXCAVATION SHALL BE BY THE AUGER METHOD TO THE NEAT LINES OF
THE OUTSIDE DIMENSION OF THE FOUNDATION WITHOUT DISTURBING THE SOIL'
AROUND AND BELOW THE PROPOSED FOUNDATION BOTTOM. ALTERNATE METHODS
OF EXCAVATION MAY BE SUBMITTED FOR APPROVAL IF THEY MEET THE
REQUIREMENTS LISTED IN THE GENERAL NOTES OF SHEETS 3 &4 OF THE
SPAN WIRE ASSEMBLY FOUNDATION DETAILS AND DESIGN CHARTS.
6. IF THE SOIL IS DISTURBED OR REMOVED BEYOND THE NEAT LINES OF THE
OUTSIDE DIMENSION OF THE FOUNDATION AS SPECIFIED, IT SHALL BE REPLACED
WITH CONCRETE. ANY ADDITIONAL COST FOR THE CONCRETE SHALL BE PAID FOR '
BY THE CONTRACTOR.
7. DETERMINATION OF EXISTING SOIL CONDITIONS SHALL BE MADE BY THE
DESIGN ENGINEER.
8. VERTICAL REINFORCEMENT BARS ARE TO BE EVENLY SPACED IN FOUNDATION AS SHOWN,
9. THE SMALLEST DIAMETER FOUNDATION SHALL BE USED THAT WILL MEET THE MOMENT 1'
REQUIREMENT AND BE AT LEAST 16" GREATER IN DIAMETER THAN THE BOLT CIRCLE DIAMETER.
10, IF A POOR SOIL OR LEDGE IS ENCOUNTERED (I.E., ONE WHICH DOES NOT APPLY TO THE DESIGN
CHARTS SHOWN ON THIS SHEET ), AN ALTERNATIVE DESIGN SHALL _BE DEVELOPED BY THE
DESIGN ENGINEER. DECISIONS MADE IN NOTES #7 & #10 SHALL BE SUBMITTED TO THE M.D.P.W.'
FOR APPROVAL . IF UTILITIES OR OTHER UNDERGROUND OBSTRUCTIONS ARE ENCOUNTERED,
THE CONTRACTOR SHALL BACKFILL THE AREA TO ITS ORIGINAL CONDITION UNTIL AN ALTERNATE
DESIGN HAS BEEN PROVIDED BY THE DESIGN ENGINEER.
11. THE FOUNDATIONS SHOWN ON THIS DRAWING ARE FOR A 35 -FOOT CANTILEVERED TYPE I I
MAST ARM CARRYING A THREE WAY, THREE SECTION, TWELVE INCH (12 ") LENS TRAFFIC SIGNAL
HOUSING FIXED AT THE END OF THE ARM, AND A ONE WAY, THREE SECTION, TWELVE INCH (12 ")
LENS TRAFFIC SIGNAL FIXED TWELVE FEET (12') AWAY, AND ANOTHER ONE -WAY, THREE SECTION
TWELVE INCH (12 ") LENS TRAFFIC SIGNAL FIXED TWELVE FEET (12') AWAY FROM THAT.
