SUPERSEDEDApproved Plan OPW22-0123

Cut and fill as required to complete the works. Assumption that civil earthworks will provide finished levels +/-
150mm from required landscape levels. Refer to Civil documents to confirm provided finished levels.
Remove spoil and excess fill from site.

The Contractor will be required to achieve smooth even grading to landscape areas. The Contractor shall
allow to remove existing plant matter, debris, rubble or other loose materials likely to interfere with the new
work, and consolidate the filling to all resulting excavations. The Contractor is required to carry out final
trimming of the entire works of the grades. Any areas of discrepancy from the Drawings should be brought to
the attention of the Landscape Architect. Fine grading shall be undertaken with a tolerance of ± 25mm.

Spot levels take precedence over contour lines and ground profile lines.

The subgrade is to be compacted to 95% minimum dry density ratio (+ 0mm- 25mm of design levels) prior to
sub-base placement. Any areas of soft ground are to be excavated & replaced with suitable fill and
compacted to prevent subsidence. Provided that all areas are free draining, and no ponding of water occurs.
Subsoil drains to have minimum fall of 1:100.

Filling in layers approximately 150 mm thick compacted to 85% of the dry density ratio of the surrounding soil
as determined by AS 1289, to minimise slumping and further internal packing down. Corners and
intersections of planes shall be rounded gradual and curves generous. To grading from edgings, provide
horizontal shoulders, minimum width 500 mm, before any change of level.

Earth Mounds
Planting mounds shall be formed from topsoil to the depths as required. The profile shall be such that the
placement of topsoil, soil mix and mulch shall bring the mounds to the finished levels shown on the drawings.
Slopes to mounds shall be no greater than 1:3 unless otherwise shown on the drawings. Ensure existing
ground levels in locations of mounds are deep ripped 150mm prior to formation of mounds.

Rake over all mounds for smooth profile.

Filling in layers as stated above.


3.5.        SETTING OUT
Prior to commencing each stage of the Landscape works, set out alignments of all paths, walls and planting
must be inspected and approved by the Landscape Architect. This may include key set-out points for
pavement pattern.
