GENERAL NOTES:GENERAL NOTES:
QUALITY ASSURANCE PROVISIONS:
1.WALL CONSTRUCTION SHALL BE SUPERVISED BY A QUALIFIED ENGINEER
OR TECHNICIAN TO VERIFY FIELD AND SITE SOIL CONDITIONS. IF THIS
WORK IS NOT PERFORMED BY THE SITE GEOTECHNICAL ENGINEER, A
QUALIFIED GEOTECHNICAL ENGINEER/TECHNICIAN SHALL BE CONSULTED
IN THOSE MATTERS PERTAINING TO THE SOIL CONDITIONS AND WALL
PERFORMANCE.
2.THE FOUNDATION SOILS AT THE BASE OF THE WALL SHALL BE INSPECTED
BY THE GEOTECHNICAL ENGINEER. ANY UNSUITABLE SOILS OR IMPROPERLY
COMPACTED EMBANKMENT MATERIAL SHALL BE REMOVED AND REPLACED
AS DIRECTED BY THE ENGINEER PRIOR TO WALL CONSTRUCTION TO
PROVIDE ADEQUATE BEARING CAPACITY AND MINIMIZE SETTLEMENT.
3.ALL WALL EXCAVATION AND RETAINED SOILS SHALL BE INSPECTED FOR
GROUNDWATER CONDITIONS. ANY ADDITIONAL DRAINAGE PROVISIONS
REQUIRED IN THE FIELD SHALL BE INCORPORATED INTO THE WALL
CONSTRUCTION AS DIRECTED BY THE GEOTECHNICAL ENGINEER.
4.WALL BACKFILL MATERIAL SHALL BE TESTED AND APPROVED BY THE
ENGINEER, MEETING THE MINIMUM REQUIREMENTS OF THE APPROVED
DESIGN PLANS OR SPECIFICATIONS.
5.ALL SOIL BACKFILL SHALL BE TESTED BY THE GEOTECHNICAL ENGINEER
FOR MOISTURE, DENSITY, AND COMPACTION PERIODICALLY (EVERY 2'
VERTICALLY, 100'-200' C/C) MEETING THE MINIMUM REQUIREMENTS OF THE
APPROVED DESIGN PLANS OR SPECIFICATIONS.
6.THE CONTRACTOR SHALL ESTABLISH AND MAINTAIN QUALITY CONTROL
FOR THE CONSTRUCTION OF THE WALL TO ASSURE COMPLIANCE WITH
CONTRACT REQUIREMENTS AND MAINTAIN RECORDS OF ITS QUALITY
CONTROL.
7.ALL WALL ELEVATIONS, GRADES, AND BACK SLOPE CONDITIONS SHALL BE
VERIFIED BY THE ENGINEER IN THE FIELD FOR CONFORMANCE WITH
APPROVED DESIGN PLANS. ANY REVISIONS TO THE STRUCTURE GEOMETRY
OR DESIGN CRITERIA SHALL REQUIRE DESIGN MODIFICATIONS PRIOR TO
PROCEEDING WITH CONSTRUCTION.

I hereby certify that this plan, specification, or report was prepared by
me or under my direct supervision and that I am a duly Licensed
Professional Engineer under the laws of the State of Minnesota.
DESIGN PROVISIONS:
1.THE FOLLOWING EFFECTIVE STRENGTH PARAMETERS WERE ASSUMED IN
THE PREPARATION OF THE STRUCTURAL CALCULATIONS FOR THE RECON
RETAINING WALL SYSTEM:
SOIL TYPES AND DESIGN PROPERTIES SHALL BE CONFIRMED BY THE SITE
GEOTECHNICAL ENGINEER PRIOR TO WALL CONSTRUCTION.
2.THE WALL IS DESIGNED TO SUPPORT THE FOLLOWING MAXIMUM
SURCHARGE LOADINGS AND GEOMETRY:
LIVE LOAD: NONE
DEAD LOAD: NONE
BACK SLOPE: 2H:1V
SEISMIC: NOT APPLICABLE
HYDROSTATIC: NOT APPLICABLE
3.THE FOUNDATION SOILS AT THE WALL LOCATIONS SHALL BE CAPABLE OF
SAFELY SUPPORTING THE MINIMUM APPLIED BEARING PRESSURE AS SHOWN
ON THE WALL PROFILES WITHOUT FAILURE OR EXCESSIVE SETTLEMENT.
LOCAL BEARING CAPACITY SHALL BE CONFIRMED BY THE SITE
GEOTECHNICAL ENGINEER AFTER FOUNDATION EXCAVATION AND PRIOR
TO WALL CONSTRUCTION.
4.DESIGN METHOD: NCMA
REFER TO PROJECT DESIGN CALCULATIONS FOR FACTORS OF SAFETY. IF
ONSITE GEOMETRY DIFFERS FROM THAT SHOWN IN THE CALCULATIONS
CDP SHALL BE CONTACTED AND A REDESIGN MAY BE NECESSARY.
