COVER SHEET

THE PROJECT SITE IS LOCATED NEAR THE ROAD RIGHT OF WAY

AT 1025-1075 CREST VALLEY DRIVE

SCOPE OF WORK:

THE STORM SEWER AT 1025-1075 CREST VALLEY DRIVE IS COMPOSED OF AN 84" DIAMETER CULVERT, AN 84"

BRICK HEADWALL, AND AN 18" CORRUGATED METAL STORM SEWER PIPE THAT DAYLIGHTS AT THE BRICK

HEADWALL.

THE 84" CORRUGATED METAL PIPE CULVERT HAS EXTENSIVE INVERT CORROSION AND DETERIORATED

CONNECTION RINGS. THE BRICK HEADWALL IS CRACKED, UNDERMINED AND SETTLED. THE 18" CMP IS

DETERIORATED DUE TO EXTENSIVE CORROSION.

THIS PROJECT AIMS TO RESOLVE THE DETERIORATION AND SETLEMENT PROBLEMS BY REHABILITATION OF THE

PIPE CULVERT, REPLACING THE BRICK HEADWALL WITH A REINFORCED CAST IN PLACE CONCRETE HEADWALL, AND REPLACING THE 18" CMP WITH AN 18" REINFORCED CONCRETE PIPE.

ADJACENT TO EXISTING STRUCTURES AND FACILITIES.

6. THE CONTRACTOR SHALL CHECK AND VERIFY ALL DIMENSIONS AND GRADE CONDITIONS (BOTH NEW

AND EXISTING), REPORTING ANY DISCREPANCIES TO THE ENGINEER PRIOR TO ORDERING MATERIALS

OR PROCEEDING WITH ANY PHASE OF THE WORK.

7. REFER TO CIVIL DRAWINGS FOR BEDDING BELOW THE HEADWALL.

8. CONTRACTOR SHALL CONTROL SITE GROUNDWATER AND/OR SURFACE WATER BY ALL MEANS

NECESSARY TO MAINTAIN A WATER LEVEL A MINIMUM 1 FEET BELOW FOUNDATION SUB-GRADE SO AS

TO NOT DAMAGE FOUNDATION EXCAVATIONS. THE BASE OF ALL FOUNDATION EXCAVATIONS SHOULD

BE FREE OF ALL WATER AND LOOSE SOIL PRIOR TO PLACING CONCRETE. ANY SUB-GRADE SOILS WHICH

HAVE BEEN WEAKENED DUE TO SATURATION OR DISTURBANCE SHALL BE RE-COMPACTED OR

REMOVED AND REPLACED WITH STRUCTURAL FILL AS DIRECTED BY THE PROJECT ENGINEER.

9. LOOSE OR SOFT SOILS SHALL BE CLEANED FROM FOUNDATION EXCAVATION BOTTOMS PRIOR TO

PLACING OF CONCRETE. SUB-GRADES NEEDING UNDERCUTTING SHALL BE BACKFILLED TO THE

ORIGINAL SUB-GRADE ELEVATION WITH COMPACTED FILL MATERIAL UNLESS DIRECTED OTHERWISE BY

THE ENGINEER. THE OVER-EXCAVATED AREA SHALL EXTEND A MINIMUM OF 1 FOOT BEYOND THE

EDGES OF THE STRUCTURE BASE SLAB OR FOOTING.

10. CONCRETE SLAB SHOULD BE PLACED AS SOON AS POSSIBLE AFTER EXCAVATIONS ARE MADE. IF THE

BEARING SOILS ARE SOFTENED BY SURFACE WATER INTRUSION OR EXPOSURE, THEN THE SOFTENED

SOILS MUST BE REMOVED FROM THE FOUNDATION EXCAVATION BOTTOM IMMEDIATELY PRIOR TO

PLACING OF CONCRETE. IF THE EXCAVATION MUST REMAIN OPEN OVERNIGHT, OR IF RAINFALL IS

IMMINENT WHILE THE BEARING SOILS ARE EXPOSED, THEN A 2- TO 3-INCH-THICK LAYER OF LEAN

CONCRETE (500 PSI MINIMUM STRENGTH) SHALL BE PLACED ON THE BEARING SOILS BEFORE THE

PLACEMENT OF REINFORCING STEEL. THE SUB-GRADE SHALL BE EXCAVATED AS REQUIRED TO

ACCEPT THE LEAN CONCRETE SO THAT THE INTENDED BOTTOM OF FOUNDATION ELEVATION IS NOT

CHANGED.

11. THE HEADWALL SLAB SHALL BE PLACED IN ONE CAST, NO HORIZONTAL JOINTS ARE PERMITTED.

12. ALL EXCAVATIONS SHALL CONFORM TO APPLICABLE OSHA REGULATIONS.

13. UNLESS NOTED OTHERWISE, ALL CONCRETE WORK, DETAILING, FABRICATION, AND PLACING OF

REINFORCING AND CONCRETE FOR THE HEADWALL STRUCTURE SHALL BE GOVERNED BY THE LATEST

REVISIONS OF: · ACI 301 "SPECIFICATIONS FOR STRUCTURAL CONCRETE". · ACI 306 AND ACI 305 FOR

COLD AND HOT WEATHER CONCRETING. · ACI 318 BUILDING CODE REQUIREMENTS FOR STRUCTURAL

CONCRETE. · CRSI RECOMMENDED PRACTICE OF PLACING REINFORCING BARS.

14. ALL CONCRETE WORK SHALL MEET GDOT STANDARD SPECIFICATION SECTION 500 EXCEPT WHERE

NOTED OTHERWISE ON THE CONSTRUCTION DRAWINGS. IF A CONFLICT EXISTS BETWEEN THE

DRAWINGS AND GDOT SPECIFICATIONS, THE MORE STRINGENT SHALL APPLY.

15. ALL CONCRETE SHALL BE NORMAL WEIGHT GDOT CLASS A AIR-ENTRAINED WITH A MAXIMUM UNIT

WEIGHT OF 150 POUNDS PER CUBIC FOOT AND SHALL HAVE A MINIMUM 28 DAY COMPRESSIVE

STRENGTH OF 3,000 PSI.

16. PROVIDE A 3/4" CHAMFER AT ALL EXPOSED CONCRETE CORNERS.

17. UNLESS NOTED OTHERWISE, REINFORCING STEEL SHALL CONFORM TO ASTM A 615, AND SHALL BE

GRADE 60.

18. CULVERT REINFORCING LAP SPLICES SHALL BE PER GDOT STANDARD 2324. REINFORCING BAR HOOK

DIMENSIONS, AND ALL OTHER REINFORCING BAR LAP SPLICES SHALL BE CLASS "B" TENSION LAPS AND

SHALL BE AS REQUIRED PER THE SCHEDULE ON CULVERT DRAWING.

· GDOT Section 805 - Rip Rap and Curbing Stone

· GSWCC 2016 Edition - Appendix C - Rip Rap

· GDOT Section 881 - Fabrics

1. Site preparation:

Streambanks shall be prepared for rip-rap installation by clearing any existing rocks and plants and creating a smooth sloped surface and compacted. The slope and location of final graded streambanks shall be according to the project construction drawings.

2. Geotextile Fabric

The geotextile fabric shall be placed over the graded and compacted sloped streambanks according to the detail provided on construction drawings. US

670 geotextile is recommended and meets the AASHTO M-288-06 requirements for Permanent Erosion Control & Subsurface Drainage.

SEDIMENT & EROSION CONTROL NOTES

AND TREE PROTECTION DETAIL

EROSION, SEDIMENTATION, AND POLLUTION CONTROL

NOTES

PRIOR TO LAND-DISTURBING ACTIVITIES, THE CONTRACTOR SHALL SCHEDULE A

PRE-CONSTRUCTION MEETING WITH THE AREA EROSION CONTROL INSPECTOR.

THE ESCAPE OF SEDIMENT FROM THE SITE SHALL BE PREVENTED BY THE

INSTALLATION OF EROSION AND SEDIMENT CONTROL MEASURES AND PRACTICES

PRIOR TO LAND DISTURBING ACTIVITIES.

EROSION CONTROL MEASURES WILL BE MAINTAINED AT ALL TIMES. IF FULL

IMPLEMENTATION OF THE APPROVED PLAN DOES NOT PROVIDE FOR EFFECTIVE

EROSION CONTROL, ADDITIONAL EROSION AND SEDIMENT CONTROL MEASURES

SHALL BE IMPLEMENTED TO CONTROL OR TREAT THE SEDIMENT SOURCE.

ANY DISTURBED AREA LEFT EXPOSED FOR A PERIOD GREATER THAN 14 DAYS

SHALL BE STABILIZED WITH MULCH OR TEMPORARY SEEDING.

ALL DISTURBED AREAS LEFT MULCHED AFTER 30 DAYS SHALL BE STABILIZED WITH

PERMANENT VEGETATION.

EROSION AND SEDIMENT CONTROL MEASURES SHALL BE INSPECTED AT LEAST

WEEKLY, AFTER EACH RAIN, AND REPAIRED AS NECESSARY.

ADDITIONAL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE INSTALLED IF

DETERMINED NECESSARY BY ON-SITE INSPECTION.

ALL SILT FENCES MUST BE TYPE C, WIRE BACKED, AND MEET THE REQUIREMENTS

OF SECTION 171-TEMPORARY SILT FENCE FOR THE GEORGIA DEPARTMENT OF

TRANSPORTATION, QUALIFIED PRODUCTS LIST #36.

ALL AMENDMENTS AND REVISIONS TO THE EROSION & SEDIMENT CONTROL PLANS

WHICH WILL HAVE A SIGNIFICANT EFFECT ON BEST MANAGEMENT PRACTICE (BMP)

WITH A HYDRAULIC COMPONENT MUST BE CERTIFIED BY THE DESIGN

PROFESSIONAL.

ALL TEMPORARY AND PERMANENT SEEDING MUST BE PERFORMED AT THE

APPROPRIATE SEASON. IN SUCH INSTANCES WHERE THE ESTABLISHMENT OF

VEGETATION IS INOPPORTUNE DUE TO SEASON OR DROUGHT, DISTURBED AREAS

SHALL BE TEMPORARILY STABILIZED USING 2”-4” OF MULCH (DS1). ADDITIONAL

PLANTINGS WILL BE NECESSARY IF A SUFFICIENT STAND OF GRASS FAILS TO GROW.

THE CITY'S DESIGNEE WILL VERIFY ADEQUATE VEGETATIVE COVER (100% COVER,

70% DENSITY) OF PERMANENT STABILIZATION (Ds3, Ds4).

SEDIMENT AND EROSION CONTROL MEASURES SHOULD BE CHECKED AFTER EACH

RAIN EVENT. EACH DEVICE IS TO BE MAINTAINED OR REPLACED IF SEDIMENT

ACCUMULATION HAS REACHED ONE HALF THE CAPACITY OF THE DEVICE.

CONTRACTOR SHALL INSPECT EROSION CONTROL MEASURES AT THE END OF EACH

WORKING DAY TO ENSURE MEASURES ARE FUNCTIONING PROPERLY.

FAILURE TO INSTALL, OPERATE, OR MAINTAIN ALL EROSION CONTROL MEASURES

WILL RESULT IN ALL CONSTRUCTION BEING STOPPED ON THE JOB UNTIL SUCH

MEASURES ARE CORRECTED BACK TO THE APPROVED EROSION CONTROL PLANS.

THE SITE CONTRACTOR WILL BE RESPONSIBLE FOR MAINTENANCE OF ALL EROSION

CONTROL MEASURES INCLUDING REPLACING OR REPAIRING ANY DAMAGED

DEVICES DUE TO ANY CONSTRUCTION ACTIVITY BY OTHERS.

DURING CONSTRUCTION, THE CONTRACTOR SHALL MAINTAIN CAREFUL

SCHEDULING AND PERFORMANCE TO ENSURE THAT LAND STRIPPED OF ITS

NATURAL GROUND COVER IS EXPOSED ONLY IN SMALL QUANTITIES AND
