EARTHWORKS NOTES
1. FOR GENERAL NOTES REFER DWG C01, WHICH IS TO BE REQUESTED AND VIEWED PRIOR TO COMMENCEMENT OF CONSTRUCTION IF NOT
EARTHWORK CUT/FILL VOLUMES: SUPPLIED.

2. FOR DETAILED GEOTECHNICAL INFORMATION, REFER GEOTECHNICAL INVESTIGATION REPORT BY TECTONIC. IT IS RECOMMENDED THAT THE
GEOTECHNICAL CONSULTANT BE CONTACTED TO CONFIRM THE SOIL CONDITIONS PRIOR TO EARTHWORKS COMMENCING.
TOTAL CUT: 778.66m³ 3. GRASS AND TOPSOIL SHALL BE STRIPPED TO A MINIMUM DEPTH OF 100MM OVER THE EXTENT OF THE WORKS UNLESS DIRECTED OTHERWISE
AND STOCKPILED WHERE REQUIRED FOR FILL OF LANDSCAPING AREAS. TOPSOIL MATERIALS MUST NOT BE USED IN STRUCTURAL FILL.
4. UNSUITABLE NATURAL MATERIALS SUCH AS SATURATED, LOOSE OR SOFT MATERIALS ENCOUNTERED SHOULD BE REMOVED DURING
TOTAL FILL: 1.64m³ SUBGRADE PREPARATION FOR BULK EARTHWORKS. ALL UNSUITABLE MATERIAL TO BE REMOVED FROM SITE AT CONTRACTORS EXPENSE.
5. COMPACTION OF THE EXPOSED SAND SUBGRADE REQUIRES SUBSTANTIAL VOLUMES OF WATER COMBINED WITH VIBRATORY COMPACTION
TEMPORARY SHORING AND/OR EQUIPMENT(E.G VIBRATING PLATE OR MINIMUM 4 TONNE VIBRATING SMOOTH DRUM ROLLER). CARE MUST BE TAKEN TO ENSURE THERE ARE
BALANCE: 777.02m³ CUT
BATTERS IN ACCORDANCE WITH NO IMPACTS ON SURROUNDING STRUCTURES. MATERIAL TO BE COMPACTED IN ACCORDANCE WITH GEOTECHNICAL REPORT AND AS1289.
6. TEMPORARY SWALE DRAINS TO BE PROVIDED ALONG CREST AND TOE OF ANY CUTS AND ABOVE FILL BATTERS GRADING DISCHARGE TO A
GEOTECHNICAL CONSULTANTS CONTROL POINT FOR DISCHARGE TO EXISTING STORMWATER INFRASTRUCTURE IN ROAD RESERVE.
SPECIFICATIONS 7. A MINIMUM 150MM THICK GRANULAR WORKING PLATFORM MAY BE REQUIRED ON SOIL SUBGRADES ALONG HAUL ROADS AND LAYDOWN AREAS
TO IMPROVE TRAFFICABILITY. SPECIFIC PLATFORM DESIGN WOULD BE REQUIRED PRIOR TO MOBILISATION AND TRAFFICKING OF ANY HEAVY
MOBILE PLANT ON THE SITE.
8. IMPORTED GENERAL FILL MATERIAL SHALL BE SUPPLIED AND COMPACTED WHERE UNSUITABLE NATURAL MATERIALS ARE LOCATED AND AS
OTHERWISE NECESSARY TO OBTAIN SUBGRADE/PLATFORM LEVEL. IMPORTED GENERAL FILL MATERIAL SHALL BE CLEAN GRADED MATERIAL
FREE OF ORGANIC MATTER AND STONES, WITH MAXIMUM PARTICLE SIZE OF 100mm AND CAPABLE OF BEING COMPACTED INTO COHERENT
FILLING TO THE SPECIFIED STANDARD. THE MATERIAL SHALL HAVE A MAXIMUM PLASTICITY INDEX OF 15%, A SHRINK-SWELL INDEX OF LESS
THAN OR EQUAL TO 1% AND A MINIMUM C.B.R. OF 10%.
9. ALL EARTHWORKS TO BE CARRIED OUT AT +/- 2% OPTIMUM MOISTURE CONTENT FOR STANDARD COMPACTION.
10. ANY PROPOSED RETAINING WALL WORKS MUST BE WHOLLY WITHIN THE PROPERTY BOUNDARY OF THE SUBJECT SITE, INCLUDING REAR OF
CH28.0 CH27.7 RETAINING WALL DRAINAGE INFRASTRUCTURE FOR RETAINING WALLS IN CUT. RETAINING WALLS ARE TO BE PREPARED IN ACCORDANCE WITH
STRUCTURAL ENGINEERS SPECIFICATIONS, AND IN CONFORMANCE WITH CONSTRUCTION REQUIREMENTS OF GEOTECHNICAL REPORT.
11. REFER ARCHITECT/LANDSCAPE ARCHITECT DRAWINGS FOR CONFIRMATION OF RETAINING WALL COLOUR AND FINISH.
12. ALL EARTHWORKS OPERATIONS SHALL BE CARRIED OUT WITH 'LEVEL 1' SOIL ENGINEERING SUPERVISION IN ACCORDANCE WITH APPENDIX B
OF AS 3798. THE NOMINATED GEOTECHNICAL TESTING AUTHORITY SHALL PROVIDE CERTIFICATION THAT ALL GENERAL EARTHWORKS

OF AT LEAST 75% IN ACCORDANCE WITH THE GEOTECHNICAL REPORT IN LAYERS OF 250MM LOOSE THICKNESS (PRIOR TO COMPACTION).
14. COMPACTION TESTING TO BE CARRIED OUT AT A MINIMUM OF TWO TESTS PER VERTICAL LIFT WHERE STRUCTURAL FILL HEIGHTS EXCEED
300MM IN ACCORDANCE WITH AS3798. CONTRACTOR TO UNDERTAKE ALL EARTHWORKS TESTING IN ACCORDANCE WITH GEOTECHNICAL
ENGINEER AND LOCAL AUTHORITY REQUIREMENTS.
15. FINISHED SURFACES TO ALL DISTURBED AREAS ARE TO BE TREATED IN ACCORDANCE WITH LANDSCAPE DRAWINGS.

18. CONTRACTOR TO ENSURE SUITABLE EROSION CONTROL MEASURES ARE INSTALLED INCLUDING BUT NOT LIMITED TO SHAKE DOWNS, SILT
FENCE ETC IN ACCORDANCE WITH EROSION AND SEDIMENT CONTROL PLAN.
19. ADEQUATE SAFETY FENCING/BARRIERS TO BE APPLIED TO ALL BATTERS OR RETAINING WALLS (TEMPORARY OR PERMANENT) AS PER
RELEVANT AUSTRALIAN STANDARDS AND LEGISLATION.
20. DUST CONTROL MEASURES ARE TO INCLUDE SPRAYING WATER ON UNPAVED ROADS, ACCESS TRACKS AND STOCKPILES AT A SUFFICIENT
LEVEL TO SUPPRESS DUST GENERATION. ADDITIONALLY CONTRACTORS ARE TO COVER OR ENCLOSE STOCKPILES WHERE REASONABLY
