DOCUMENTS AND AS REQUIRED BY PERMITS. GRADE SIDE SLOPES, SHOULDER AREAS AND DISTURBED VEGETATED AREAS TO A MAXIMUM SLOPE OF 3
HORIZONTAL TO 1 VERTICAL (3H:1V), WHERE POSSIBLE. PROVIDE BIODEGRADABLE EROSION CONTROL BLANKETS TO PREVENT EROSION WHERE SLOPES
ARE STEEPER THAN 3H:1V.

8.MAINTAIN AN ADDITIONAL SUPPLY OF EROSION CONTROL MEASURES ON-SITE FOR EMERGENCY REPAIRS.
9.STORE FUEL, OIL, PAINT, OR OTHER HAZARDOUS MATERIALS IN A SECONDARY CONTAINER AND REMOVE TO A SECURE LOCKED AND COVERED AREA

REINFORCEMENT
1.DETAILING, FABRICATION, AND ERECTION OF REINFORCEMENT, UNLESS OTHERWISE NOTED, SHALL
CONFORM TO ACI "BUILDING CODE REQUIREMENTS FOR REINFORCED CONCRETE (ACI 318)" AND ACI
"MANUAL OF STANDARD PRACTICE FOR DETAILING REINFORCED CONCRETE STRUCTURES (ACI 315)",
LATEST EDITION.
2.STEEL REINFORCEMENT UNLESS OTHERWISE SHOWN SHALL CONFORM TO ASTM A615 GRADE 60 MINIMUM
(YIELD STRENGTH - 60,000 PSI).
3.THE CONCRETE PROTECTIVE COVERING FOR REINFORCEMENT SHALL BE 3 INCHES FOR CAST-IN-PLACE
CONCRETE CAST AGAINST EARTH, OR EXPOSED TO WATER OR WEATHER AND 1 1/2 INCHES IF
CAST-IN-PLACE IS NOT CAST AGAINST EARTH, OR EXPOSED TO WATER OR WEATHER, UNLESS OTHERWISE
SHOWN.
4.WHERE REINFORCEMENT IS CALLED FOR IN SECTION, REINFORCEMENT IS CONSIDERED TYPICAL
WHEREVER THE SECTION APPLIES.
5.REINFORCEMENT SHALL BE CONTINUOUS THROUGH ALL CONSTRUCTION JOINTS UNLESS OTHERWISE
INDICATED ON THE DRAWINGS.
6.REINFORCEMENT SHALL BE SET BEFORE PLACING CONCRETE. SETTING ANY REINFORCEMENT INTO WET
CONCRETE IS PROHIBITED.
FOUNDATIONS
1.NO CONCRETE SHALL BE PLACED IN WATER OR ON FROZEN GROUND.
2.BOTTOM OF FOUNDATION ELEVATIONS GIVEN ON DRAWINGS ARE TO BE CONSIDERED MINIMUM DEPTHS.
CONTRACTOR SHALL HAVE FURTHER EXCAVATION AS REQUIRED TO REACH FIRM BEARING SURFACE AS
DETERMINED BY ENGINEER.
3.REMOVE UNSUITABLE MATERIAL AND REPLACE WITH MATERIAL AS DIRECTED BY ENGINEER.
4.FROZEN MATERIAL MAY NOT BE USED AS BACKFILL.
CONCRETE
1.CONCRETE WORK SHALL CONFORM TO THE LATEST EDITIONS OF THE BUILDING CODE REQUIREMENTS FOR REINFORCED
CONCRETE (ACI 318), AND SPECIFICATIONS FOR STRUCTURAL CONCRETE FOR BUILDING (ACI 301.
2.CONCRETE SHALL BE NORMAL WEIGHT CONCRETE AND SHALL HAVE A COMPRESSIVE STRENGTH OF 4,500 PSI AT 28 DAYS, SHALL
BE AIR ENTRAINED BETWEEN 4.5 AND 7.5 PERCENT, SHALL HAVE MAXIMUM WATER/CEMENT RATIO OF 0.45, AND SHALL HAVE A
TOTAL CEMENTITIOUS MATERIAL IN THE MIX BETWEEN 635 LBS (MIN) AND 658 LBS (MAX) PER CUBIC YARD.
3.CONCRETE MATERIALS:
3.1.PORTLAND CEMENT: TYPE II, MEETING REQUIREMENTS OF ASTM C150
3.2.FLY ASH: CLASS F CONFORMING TO ASTM C989
3.3.GROUND GRANULATED BLAST SLAG: CONFORMING TO ASTM C989
3.4.FINE AGGREGATE: NATURAL SAND CONFORMING TO ASTM C33 WITH A FINENESS MODULUS = 2.75 (PLUS/MINUS 0.25)
3.5.COARSE AGGREGATE: 3/4" PROCESSED STONE CONFORMING TO ASTM C33
3.6.WATER: SHALL BE CLEAN, POTABLE
3.7.MID-RANGE WATER REDUCING AGENT: CONFORMING TO ASTM C494 TYPE A
3.8.HIGH-RANGE WATER REDUCING AGENT: CONFORMING TO ASTM C494 TYPE F
3.9.AIR-ENTRAINING AGENT: CONFORMING TO ASTM C260
4.CONCRETE SLAB SHALL BE CAST SO THAT THE SLAB THICKNESS IS AT NO POINT LESS THAN THAT INDICATED ON THE DRAWINGS.
5.CONCRETE SHALL BE PLACED WITHOUT HORIZONTAL CONSTRUCTION JOINTS EXCEPT WHERE SHOWN OR NOTED.
6.ALL CONCRETE SHALL BE CURED IMMEDIATELY AFTER FINISHING IN ACCORDANCE WITH THE FOLLOWING REQUIREMENTS: CURING
SHALL BE ACCOMPLISHED BY A CONTINUOUS SOAKING PROCESS SUCH AS THE USE OF SOAKER HOSE OR SPRINKLERS, OR BY USE
OF PLASTIC ROLL MATERIALS TO COVER THE CONCRETE, WHICH SHALL BE THOROUGHLY WETTED AT LEAST ONCE A DAY OR MORE
OFTEN AS REQUIRED IN VERY HOT WEATHER. SUCH PLASTIC SHALL BE PLACED AS SOON AS POSSIBLE AFTER FINISHING OF
CONCRETE AS IS PROPER SO THAT SCARRING OF THE SURFACE WILL NOT OCCUR. PLASTIC SHALL BE HELD IN PLACE ON THE
SURFACE OF THE CONCRETE IN SUCH A MANNER AND MEANS AS WILL NOT ALLOW IT TO BE BLOWN OFF OR OTHERWISE
DISLODGED FROM THE CONCRETE SURFACE. CURING PROCEDURES SHALL BE MAINTAINED CONTINUOUSLY FOR A PERIOD OF AT
LEAST 7 DAYS.
7.CONCRETE SHALL NOT BE ALLOWED TO FLOW HORIZONTALLY OVER DISTANCES EXCEEDING 10 FEET OR DROPPED VERTICALLY
OVER 6 FEET.
8.THOROUGHLY CONSOLIDATE EACH LAYER OF CONCRETE BY RODDING AND VIBRATING USING INTERNAL TYPE MECHANICAL
VIBRATOR.
9.IMMEDIATELY AFTER THE END OF THE WET CURE PERIOD, REMOVE FROM TIES AND PATCH ALL TIE-HOLES, RAT HOLES AND OTHER
SURFACE VOIDS WITH A NON-METALLIC, NON-SHRINK GROUT, WHICH MOST NEARLY MATCHES THE COLOR AND TEXTURE OF THE
CONCRETE SURFACE. ALL PROTRUSIONS SHALL BE GROUND SMOOTH WITH AN APPROVED MECHANICAL GRINDER.
10.COLD WEATHER CONDITIONS SHALL BE IMPLEMENTED IN ACCORDANCE WITH ACI 306.1-90 WHEN FOR MORE THAN THREE
SUCCESSIVE DAYS THE AVERAGE DAILY OUTDOOR TEMPERATURE DROPS BELOW 40°F.
11.DURING COLD WEATHER CONCRETE PROCEDURES, THE CONCRETE TEMPERATURE AT THE TIME OF PLACEMENT SHALL BE
