SITE _DEWATERING

— THE SITE IS TO BE CONSTANTLY DE-WATERED UNTIL THE GROUND
LEVEL SUSPENDED SLAB IS POURED.

— THE DESIGN AND INSTALLATION OF THE DEWATERING SYSTEM IS TO
BE BY A SPECIALIST CONTRACTOR.

—APPROX GROUND WATER TABLE OF 1.0m BELOW EXISTING GROUND
LEVEL. SEASONAL & TIDAL VARIATIONS NOT CONSIDERED

—GIVEN THE CLOSE PROXIMITY TO THE NOOSA RIVER, GROUNDWATER
LEVELS WILL VARY WITH TIDAL INFLUENCE AND PREVAILING WEATHER
CONDITIONS.

—EXTRACTED GROUNDWATER IS TO BE TREATED IN ACCORDANCE WITH
RECOMMENDATIONS PROVIDED IN A FUTURE DEWATERING MANAGEMENT
PLAN & SITE GEOTECHNICAL REPORT

— TREATED EXTRACTED GROUNDWATER IS TO BE DIRECTED TO COUNCIL
STORMWATER, FINAL OUTLET LOCATION TO BE APPROVED BY NOOSA
COUNCIL.

— PUMPING MUST NOT CAUSE NUISANCE FOR NIEGHBOURS. ENCLOSING
WITHIN A SOUND PROOF ENCLOSURE MUST BE CONSIDERED.

 

 

 

 

TEMPORARY CFA PILED RETAINING WALLS
— CFA PILED RETAINING WALL DESIGN AND INSTALLATION
BY A SPECIALIST CONTRACTOR

— DRIVING OF PILE WALLS NOT PERMITTED

— INSTALLATION OF GROUND ANCHORS INTO NEIGHBORING
PROPERTIES NOT PERMITTED WITHOUT OWNERS CONSENT
— ADDITIONAL MEASURES SUCH AS GROUTING THE JOINTS
IS RECOMMENDED TO REDUCE GROUNDWATER INFLOWS.

— PROVIDE GROUND MONITORING/VIBRATION CONTROL
DURING INSTALLATION.

— ESTABLISH SURVEY MONITORING POINTS ALONG PILED
WALL TO MONITOR WALL ALIGNMENT/ GROUND MOVEMENT

CONSTRUCTION NOTES

GENERAL:

1. DO NOT SCALE FROM THIS DRAWING.

2. ALL DIMENSIONS IN MILLIMETRES

3. SETTING OUT DIMENSIONS ARE TO BE OBTAINED FROM THE
ARCHITECTURAL DRAWINGS.

4. ANY DISCREPANCIES BETWEEN THESE DRAWING AND THE
ARCHITECTURAL DRAWINGS ARE TO BE REFERRED TO THE
ENGINEER IMMEDIATELY.

5. THE BUILDER IS RESPONSIBLE FOR LOCATING ALL EXISTING
SERVICES WITHIN AND ADJACENT THE ALLOTMENT AND SHALL
ENSURE THAT ALL NEW WORKS ARE IN ACCORDANCE WITH
THE ATTACHED CRITICAL DEPTH LINE DIAGRAM.

FILLING NOTES

—THE SITE IS TO BE SCRAPED CLEAR OF ALL ORGANIC
MATERIAL AND DEBRIS.

—THE SUBGRADE IS TO BE ROLLED WITH A VIBRATING STEEL
DRUM ROLLER TO ACHIEVE A MINIMUM RELATIVE FIELD
DENSITY OF 98%. THE COMPACTION IS TO BE SUFFICIENT TO
ACHIEVE A BLOW COUNT OF 7 BLOWS PER 300mm WITH AN
APPROVED PERTH SAND PENETROMETER FOR A DEPTH OF
1.0m BELOW EXCAVATED LEVEL. COPIES OF COMPACTION TEST
RESULTS SHALL BE PRESENTED TO SCG CONSULTING
ENGINEERS FOR APPROVAL.

—UNLESS NOTED OTHERWISE A MINIMUM BEARING CAPACITY
OF 100kPa SHOULD BE ACHIEVED WITHIN COMPACTED FILLING.
COMPACTION & BEARING CAPACITY TEST RESULTS MUST BE
PRESENTED TO SCG CONSULTING ENGINEERS FOR APPROVAL
PRIOR TO WORKS PROCEEDING.

—THE FILL MATERIAL CLEAN GRANULAR MATERIAL (I.E. SAND
TO A CLAYEY SAND IN ACCORDANCE WITH AS1726) BE FREE
OF ANY ORGANIC MATERIAL AND HAVE A CLAY CONTENT OF
LESS THAN 12% (PLASTICITY INDEX LESS THAN 25%, LINEAR
SHRINKAGE OF 15%). THE PROPOSED MATERIAL IS TO BE
INSPECTED BY SCG CONSULTING ENGINEERS PRIOR TO ITS
REMOVAL TO ENSURE ITS COMPATIBILITY.

—THE FILL IS TO BE PLACED AND COMPACTED IN
ACCORDANCE WITH AS3798-1996 TO A LEVEL SUFFICIENT TO
ACHIEVE A LEVEL 2 CERTIFICATION WITH A MINIMUM RELATIVE
FIELD DENSITY OF 98%. COPIES OF COMPACTION TEST
RESULTS SHALL BE PRESENTED TO SCG CONSULTING
ENGINEERS FOR APPROVAL.

FILLING AND COMPACTING ADJACENT EXISTING STRUCTURES
IS TO BE IN STRICT ACCORDANCE WITH THE ASSOCIATED
DETAILS AND SPECIFICATIONS.

—AREAS WHERE EXISTING STRUCTURES OR TREES ARE
REMOVED SHALL BE BACKFILLED WITH THE APPROVED FILL
MATERIAL COMPACTED IN ACCORDANCE WITH AS2870-1996 TO
ACHIEVE A MINIMUM RELATIVE FIELD DENSITY OF 987.

—ANY LOOSE OR SOFT MATERIAL UNCOVERED IN THE SITE
PREPARATION SHALL BE REMOVED AND REPLACED WITH THE
APPROVED FILL MATERIAL COMPACTED IN ACCORDANCE WITH
AS2870-1996 TO ACHIEVE A MINIMUM RELATIVE FIELD
DENSITY OF 98%.

—SITE DRAINAGE AND SILT PROTECTION MEASURES MUST BE
ISTALLED PRIOR TO CONSTRUCTION COMMENCING.
