-1.9 to -1.8 m 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,
-1.8 to -1.7 m INCLUDING REAR OF 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
-1.7 to -1.6 m REQUIREMENTS OF GEOTECHNICAL REPORT.
11. REFER ARCHITECT/LANDSCAPE ARCHITECT DRAWINGS FOR CONFIRMATION OF RETAINING WALL COLOUR AND FINISH.
-1.6 to -1.5 m
12. ALL EARTHWORKS OPERATIONS SHALL BE CARRIED OUT WITH 'LEVEL 1' SOIL ENGINEERING SUPERVISION IN ACCORDANCE
28.00m 27.99m 27.99m
-1.5 to -1.4 m
WITH APPENDIX B OF AS 3798. THE NOMINATED GEOTECHNICAL TESTING AUTHORITY SHALL PROVIDE CERTIFICATION THAT ALL
GENERAL EARTHWORKS OPERATIONS HAVE BEEN CARRIED OUT IN ACCORDANCE WITH THE DRAWINGS AND SPECIFICATIONS
-1.4 to -1.3 m
AND THE CONTROLLED FILL IS SUITABLE FOR PURPOSE TO THE REQUIRED BEARING CAPACITY UNDER THE
PLATFORM/STRUCTURES AS SPECIFIED BY THE GEOTECHNICAL REPORT.
-1.3 to -1.2 m 13. ALL EARTHWORKS FILL AND EXCAVATED AREAS SHALL BE COMPACTED TO 98% STANDARD MAXIMUM DRY DENSITY OR A DRY
DENSITY INDEX OF AT LEAST 75% IN ACCORDANCE WITH THE GEOTECHNICAL REPORT IN LAYERS OF 250MM LOOSE THICKNESS
-1.2 to -1.1 m (PRIOR TO COMPACTION).
14. COMPACTION TESTING TO BE CARRIED OUT AT A MINIMUM OF TWO TESTS PER VERTICAL LIFT WHERE STRUCTURAL FILL
-1.1 to -1.0 m HEIGHTS EXCEED 300MM IN ACCORDANCE WITH AS3798. CONTRACTOR TO UNDERTAKE ALL EARTHWORKS TESTING IN
ACCORDANCE WITH GEOTECHNICAL ENGINEER AND LOCAL AUTHORITY REQUIREMENTS.
