SITE CONDITIONS:

Vegetation: Grasses, large paim and shrubs,
Crossfall: 0.2m over allotment

Drainage: Front/rear. Poor,

Adjacent Constructian: Existing two storey mote! units.
Water Table: 1.2/1.5.

Remarks: This report should form the basis for a Preliminary site review which should be
augmented at a ater date. The site is located on the southem flank of Noosa River
and adjacant a remnant tidal inlet (Noosa Waters Estate) Load bearing structures
will be subject to significant settlements due to consolidation of underlying
ailuvial/marine sediments and clays The expected settiements and duration over
which they will occur should be consistent over the site due to the uniformity of sub-
soil types. Founding options for this site could include;- a stiffened raft designed to
tolerate substantial settiements or piled foundation system, To conclude the
appropriate foundation system, we would recommiend two static cone test bores to
depths of 9 metres with an additional borehole to the south-eastern alletment sectors
combined with a series of four additional dynamic cone penetrometer tests to 3.0
metres. Boreholes (3) revealed filling to depths ranging 0.6/0.9 metres.
Penetrometer values insitu fill material indicate poorfair consistencies, Remnant
(G1.) clay top-soil up to 0.3 metres thick with medium dense sands underlying, An
Clay/silt percentages increase, the bearing capacity and penetmmeter values
generally reduce to range from poorfairfmoderate consistencies, A
weaklyimoderately cemented layer approximately 0.3 metres thick wes encountered
at depths of 2.7 to 3.0 matres Sande below the minor Cemented layer were
generally fine grained and with significant clay/silt percentages. Claysy sands and
altuviel sandy clays were at further depth and extending to 5.8 metres. Sands above
the cemented layer had shell pieces insitu.
