21. NOTE TO CONTRACTORS
ONLY THE FOLLOWING MATERIALS ARE SUPPLIED BY THE REINFORCED EARTH COMPANY:
- PRECAST CONCRETE FACING PANELS
- SOIL REINFORCEMENTS
- BOLT SETS (FOR ATTACHING PANELS TO THE SOIL REINFORCEMENTS)
- BEARING BLOCKS
- RUBBER SHIMS
- FILTER CLOTH AND ADHESIVE (FOR PANEL JOINTS ONLY)
ANY OTHER MATERIALS CALLED FOR IN THE CONTRACT PLANS OR SPECIFICATIONS ARE TO BE SUPPLIED BY THE CONTRACTOR. ANY JOINT MATERIALS SHOWN AT THE INTERFACE OF PRECAST PANELS AND CASTIN-PLACE CONCRETE STRUCTURES ARE TO BE SUPPLIED BY THE ERECTION CONTRACTOR. ALL SANDBLASTING, PAINTING, SEALERS OR OTHER SPECIAL APPLIED COATINGS ARE ALSO SUPPLIED/INSTALLED BY THE CONTRACTOR IN THE FIELD FOLLOWING PANEL ERECTION.
22. THE REINFORCED EARTH COMPANY SUPPLIES PRECAST CONCRETE FACING PANELS AND ACCESSORIES TO BE USED IN CONJUNCTION WITH OTHER MATERIALS IN THE CONSTRUCTION OF THE REINFORCED EARTH RETAINING WALLS DETAILED HEREIN. THE CONSTRUCTION AND QUALITY CONTROL PROCEDURES MANUAL FURNISHED BY THE REINFORCED EARTH COMPANY IS INTENDED TO PROVIDE A GENERAL EXPLANATION OF THE SYSTEM. IT IS THE CONTRACTOR'S OBLIGATION TO DEVISE AND EXECUTE A PROJECT SPECIFIC ERECTION SEQUENCE, PANEL UNLOADING, HANDLING AND BRACING SYSTEM, AND FALL PROTECTION SYSTEM. THE BRACING SYSTEM SHOWN IN THE CONSTRUCTION AND QUALITY CONTROL PROCEDURES MANUAL IS GENERAL IN NATURE AND DOES NOT ACCOUNT FOR PROJECT SPECIFIC CRITERIA. COMPLIANCE WITH THE GUIDELINES IN THIS MANUAL DOES NOT RELIEVE THE CONTRACTOR OF ITS RESPONSIBILITY TO ADHERE TO THE PROJECT PLANS, SPECIFICATIONS AND CONTRACT DOCUMENTS OR COMPLIANCE WITH ALL FALL PROTECTION, SAFETY, LAWS, STANDARDS AND PROCEDURES AT THE JOBSITE. CONTRACTORS SHOULD TAKE SPECIAL PRECAUTIONS TO PREVENT THE PANELS FROM SHIFTING OR FALLING DURING THE ERECTION PROCESS.
23. THE DESIGN CONTAINED ON THESE DRAWINGS IS BASED ON INFORMATION PROVIDED BY THE OWNER. ON THE BASIS OF THIS INFORMATION, THE REINFORCED EARTH COMPANY IS RESPONSIBLE FOR INTERNAL STABILITY OF THE STRUCTURE ONLY. EXTERNAL STABILITY DESIGN INCLUDING FOUNDATION AND SLOPE STABILITY IS THE RESPONSIBILITY OF OTHERS.
24. THESE DRAWINGS ARE CERTIFIED WITH RESPECT TO THE INTERNAL STABILITY OF REINFORCED EARTH STRUCTURES ONLY.
25. THIS DRAWING CONTAINS INFORMATION PROPRIETARY TO THE REINFORCED EARTH COMPANY, AND IS BEING FURNISHED FOR THE USE IN CONNECTION WITH FOOT PROJECTS ONLY, AND THE INFORMATION CONTAINED HEREIN IS NOT TO BE TRANSMITTED TO ANY OTHER
ORGANIZATION UNLESS SPECIFICALLY AUTHORIZED IN WRITTING BY THE REINFORCED EARTH COMPANY. THE REINFORCED EARTH COMPANY IS EXCLUSIVE LICENSEE IN THE UNITED STATES UNDER PATENTS ISSUED TO HENRY VIDAL, AND THE FURNISHING OF THIS DRAWING DOES NOT CONSTITUTE AN EXPRESSED OR IMPLIED LICENSE UNDER THE VIDAL PATENTS.
THIS SYSTEM SHALL BE USED IN SLIGHTLY OR MODERATELY AGGRESSIVE ENVIRONMENTS ONLY.
CRUCIFORM AND SQUARE PANELS

DESIGN CRITERIA

DESIGN IS BASED ON THE ASSUMPTION THAT THE MATERIAL WITHIN THE
REINFORCED EARTH VOLUME, METHODS OF CONSTRUCTION AND QUALITY
OF PREFABRICATED MATERIALS SHALL CONFORM TO THE CONTRACTING
AGENCY'S TECHNICAL SPECIFICATIONS (SECTION 548) FOR REINFORCED
EARTH WALLS
12.
BACKFILL MATERIAL SHALL BE COMPACTED IN ACCORDANCE WITH SEC 548
TO A LEVEL OF 2"± ABOVE THE TIE STRIPS EMBEDDED IN THE PANELS.
INSTALLATION OF SOIL REINFORCEMENTS SHALL BE PERMITTED ONLY AFTER
PLACEMENT AND COMPACTION OF THE BACKFILL MATERIAL HAS REACHED
THE REQUIRED LEVEL.

13.
IF STRUCTURES IN EXCESS OF 20' IN HEIGHT OCCUR, THE FINISHED GRADE
2.
SOIL PARAMETERS:
SEE WALL CONTROL DRAWINGS FOR SOIL CHARACTERISTICS OF FOUNDATION
MATERIAL TO BE USED IN THE DESIGN OF THE WALL SYSTEM. THE
CONTRACTOR SHALL PROVIDE SOIL DESIGN PARAMETERS FOR BACKFILL
MATERIAL BASED ON THE ACTUAL SOIL CHARACTERISTICS UTILIZED AT

IN FRONT OF THE WALL SHALL BE PLACED AND COMPACTED BEFORE WALL
CONSTRUCTION EXCEEDS A HEIGHT OF 20'. FINISHED GRADE BACKFILL
SHALL BE COMPACTED TO 95% OF AASHTO T-180 UNLESS OTHERWISE
DIRECTED BY THE ENGINEER.

THE SITE. THE VALUES OF FRICTION ANGLE (0), COHESION ( c ) AND
TOTAL UNIT WEIGHT ( y ) SHALL BE PROVIDED IN THE SHOP DRAWINGS.
14.
IT IS THE CONTRACTOR'S RESPONSIBILITY TO DETERMINE THE LOCATION
OF ANY GUARDRAIL POSTS BEHIND THE REINFORCED EARTH PANELS PRIOR
TO PLACEMENT OF THE TOP LAYER OF SOIL REINFORCEMENTS. INDIVIDUAL
REINFORCEMENTS MAY BE SKEWED UP TO 15' TO AVOID THE POST LOCATIONS
3.
THE MAXIMUM APPLIED BEARING PRESSURE AT THE FOUNDATION LEVEL
IS AS SHOWN ON THE WALL ELEVATIONS FOR EACH DESIGN CASE.
IT IS THE RESPONSIBILITY OF THE OWNER TO DETERMINE THAT THIS
APPLIED BEARING PRESSURE IS ALLOWABLE FOR THAT LOCATION.

IF AUTHORIZED BY THE ENGINEER. ANY DAMAGE DONE TO THE
SOIL REINFORCEMENTS DUE TO THE INSTALLATION OF THE GUARDRAIL SHALL
BE REPAIRED BY THE CONTRACTOR AT THE CONTRACTOR'S EXPENSE.

15.
IF EXISTING OR FUTURE STRUCTURES, PIPES, FOUNDATIONS OR GUARDRAIL
4.
ANY UNSUITABLE FOUNDATION MATERIAL BELOW THE REINFORCED EARTH
VOLUME, AS DETERMINED BY THE ENGINEER, SHALL BE EXCAVATED AND
REPLACED WITH SUITABLE MATERIAL OR OTHERWISE STABILIZED AS
DIRECTED BY THE ENGINEER.

POSTS WHICH ARE WITHIN THE REINFORCED EARTH VOLUME INTERFERE
WITH THE NORMAL PLACEMENT OF SOIL REINFORCEMENTS AND SPECIFIC
DIRECTION HAS NOT BEEN PROVIDED ON THE PLANS, THE CONTRACTOR
SHALL NOTIFY THE ENGINEER TO DETERMINE WHAT COURSE OF
ACTION SHOULD BE TAKEN.
5.
REINFORCING STRIPS FOR REINFORCED EARTH WALLS SHALL BE 1 31/32"
WIDE AND 5/32" THICK, AND SHALL CONFORM TO THE PHYSICAL AND

MECHANICAL PROPERTIES OF ASTM A-572 GRADE 65. GALVANIZATION
SHALL BE APPLIED IN ACCORDANCE WITH ASTM A-123.
16.
TOP PANELS BENEATH COPING SHALL HAVE #4 DOWELS PROTRUDING
FROM THEIR TOP EDGE.

17.
FOR OTHER INFORMATION PERTAINING TO WALL CONSTRUCTION PLEASE
6.
HA LADDERS SHALL BE SUPPLIED BY THE REINFORCED EARTH COMPANY,
AND SHOP FABRICATED OF COLD DRAWN STEEL WIRE CONFORMING TO THE
PHYSICAL AND MECHANICAL PROPERTIES OF ASTM A-82. ALL WELDING

REFER TO THE REINFORCED EARTH CONSTRUCTION MANUAL.

SHALL BE IN ACCORDANCE WITH ASTM A-185. GALVANIZING FOR
PERMANENT WALL SYSTEMS SHALL CONFORM TO THE MINIMUM
REQUIREMENTS OF ASTM A-123 OR AASHTO M111 (2 OZ/SQ. FT.).
HA LADDER REINFORCEMENTS MAY BE USED ONLY ON WALLS WITH
HEIGHTS 20 FT OR LESS.
18.
THE CONTRACTOR IS RESPONSIBLE FOR GRADUALLY DEFLECTING UPPER
SOIL REINFORCEMENTS DOWNWARD TO AVOID CONFLICTS WITH PAVING AND
SUBGRADE PREPARATION. THE CONTRACTOR'S ATTENTION IS DIRECTED
ESPECIALLY TO SITUATIONS WHERE ROADWAY SUPERELEVATION AND/OR
SOIL MIXING ARE ANTICIPATED.
7. THE MINIMUM FACTORS OF SAFETY REQUIRED FOR DESIGN
OVERTURNING = 2.0
SLIDING = 1.5
INTERNAL PULLOUT = 1.5 (ALLOWABLE DEFORMATION = 0.75 INCH) BEARING CAPACITY = 2.5
OVERALL STABILITY = 1.5
STEEL SOIL REINFORCEMENT = 0.55Fy AT END OF DESIGN LIFE
AND 0.50 Fu AT NET SECTION OF BOLTED CONNECTION
MAXIMUM PULLOUT FACTOR f* (FOR SAND) = 1.5
(FOR LIMEROCK) = 2.0
WALL CONSTRUCTION
8. REINFORCED EARTH WALLS IN CURVES WILL FORM A SERIES OF SHORT CHORDS OF 4'-11" EACH TO MATCH DESIRED WALL ALIGNMENT.
MATERIALS NOTES
19. NOMINAL SOIL REINFORCEMENT LENGTHS
THE SOIL REINFORCEMENT LENGTHS SHOWN ON THE PLANS, MEASURED FROM BACK FACE OF PANEL, ARE THE NOMINAL LENGTHS REQUIRED BY CALCULATION. THE ACTUAL FABRICATED REINFORCEMENT LENGTHS ARE OFTEN LONGER (UP TO 6") DUE TO MANUFACTURING TOLERANCES. THE REQUIRED HORIZONTAL LIMIT OF GRANULAR BACKFILL IS EQUAL TO THE NOMINAL SOIL REINFORCEMENT LENGTH.
20. PANEL FINISH
THE PRECAST PANELS FOR THIS PROJECT SHALL HAVE A PLAIN STEEL FINISH UNLESS OTHERWISE SPECIFIED ON THE RETAINING WALL CONTROL PLANS.
9. FOR LOCATION AND ALIGNMENT OF REINFORCED EARTH WALLS, SEE RETAINING WALL CONTROL PLANS.
10. IF MANHOLES AND DROP INLETS ARE PRESENT, THEY SHALL BE LOCATED AS SHOWN ON WALL ELEVATIONS.
