1.0 INTRODUCTION
This report details the results of a geotechnical investigation carried out for a proposed unit development at
Lots 5 to 8, Settlers Cove, Serenity Close, Noosa Heads. The investigation was undertaken at the request of
Tate Professional Engineers Pty Ltd (Tate), the consulting engineers for the project, on behalf of the client
CBD Settlers Cove Pty Ltd.
Information supplied to us by Tate indicates that the proposed development comprises two and four level
structures of masonry construction, a pool and associated infrastructure. The four storey buildings will be
over single level, slab on ground basements. We are advised that stormwater disposal for the site will be via
Rapid Infiltration Pits (RIPs) which discharge through a permeable base no less than 2 m below the ground
surface.
This report summarises the results of the investigation and includes an assessment of slope stability
together with geotechnical recommendations regarding the design of earthworks, footings, retaining
structures and pavements.
2.0 SITE DESCRIPTION
Site is located at the western end of Serenity Close, Noosa Heads.
At the time of the investigation (Ref. Photograph 1 below), the proposed development area was covered by
grass and mulch with stands of vegetation. The ground surface sloped towards the south and south west at
angles of between about 5o to 8o. The ground slope increases (up to about 35º) in the southern and western
parts of the site within densely vegetated land down to Noosa Inlet.
The site layout, together with ground surface contours and photographs illustrating the site conditions at the
time of the investigation are shown on Figure No. 1.
3.0 METHOD OF INVESTIGATION
The investigation comprised a terrain assessment by a senior geotechnical engineer together with a
subsurface investigation by geotechnical personnel carried out between 29 to 31 October 2008. The
subsurface investigation comprised twenty boreholes (designated BH1 to BH20) drilled using a 4WD
mounted solid flight auger rig to depths of 6 m.
In-situ soil density was assessed by conducting dynamic cone penetrometer (DCP) tests from the ground
surface adjacent to each borehole and at various depths within the boreholes following augering (in order to
minimise the effect of rod friction on the test results).
Borehole locations are shown in Figure No. 1, Site Plan. Results of the fieldwork are presented in the
Reports of Boreholes in Appendix A, along with explanatory notes.
4.0 SUBSURFACE CONDITIONS
Available geological information1 indicates that the site is underlain by Quaternary (Pleistocene) age quartz
dune sand.
The subsurface conditions encountered in the boreholes generally comprised very loose to loose sand to
depths of between 0.4 m to 2.3 m, then dense sand to between about 2.7 m and 4.1 m depth, underlain by
medium dense to dense sand to the depth of investigation (ie. about 6 m).

LOTS 5 TO 8, SETTLERS COVE, SERENITY CLOSE, NOOSA Some fill comprising sandy gravel was encountered in borehole BH1 to 0.4 m below ground level (BGL). Silty sand was encountered in boreholes BH2, BH3 and BH14 to depths of between 0.4 m and 0.5 m BGL. Sandy gravel was encountered in borehole BH3 from the ground surface to 0.2 m BGL. Groundwater was not encountered in any of the boreholes at the time of the investigation. These results are similar to those from previous investigations on Lots 2 and 3, nearby (ref. Golder Reports 06682026(AA) and 97680045(B)). 5.0 COMMENTS AND RECOMMENDATIONS 5.1 Slope Stability The steep dune face in the northern part of the site is described as a ‘Sand Dune Problem Area’ in Noosa Council’s Planning Scheme. Details on the stability of the site have been provided in earlier geotechnical reports by Golder Associates for the ‘Settlers Cove’ development (Ref. 91680133). These previous reports indicate that the steep dune face is marginally stable. The existing steep slope of the dune face (up to about 35º) appears to be maintained at more than the normal angle of repose for loose sand (about 27º) by the mechanical binding action of the roots associated with the dense cover of vegetation. The edge of the development area, near the crest of the steep slope, corresponds to the Zone 1/Zone 2 boundary as defined in previous reports. Zone 1 includes all the steep dune face, plus a margin on the uphill side of the crest to allow for the unlikely event that three subsequent and effectively cumulative translational slide failures develop down the dune face. The remaining near level areas are Zone 2. In accordance with previous practice in the area, it is recommended that all structures are founded below a plane rising at 27º from the toe of the steep dune face (Ref. Figure No. 2). For this proposed development, the position and levels are such that relatively shallow foundations will be suitable. Provided the dune face is managed as detailed in earlier reports (eg. retain existing vegetation), it is our opinion that there is a Very Low to Low Risk of slope instability affecting the proposed development and that the development should not detrimentally affect the stability of the dune face. Subsurface disposal of stormwater via RIPs with outlets at least 2 m below the ground surface must not occur within 5 m of the crest of the dune face (ref. Figure No. 1). The risk assessment for this project has been carried out following the Australian Geomechanics Society (AGS) Guidelines for Landslide Risk Management (March 2007). Relative levels of risk and their implications are given in Table 1 below. December 2008 Report No. 087682058 002 Rev.1 2

Table 1: Stability Risk Levels
Risk Level Example Implications(1)
VH VERY HIGH RISK Unacceptable without treatment. Extensive detailed
investigation and research, planning and implementation
of treatment options essential to reduce risk to Low; may
be too expensive and not practical. Work likely to cost
more than value of property.
H HIGH RISK Unacceptable without treatment. Detailed investigation,
planning and implementation of treatment options required
to reduce risk to Low. Work would cost a substantial sum
in relation to the value of the property.
M MODERATE RISK May be tolerated in certain circumstances (subject to
regulators’ approval) but requires investigation, planning
and implementation of treatment options to reduce risk to
Low. Treatment options to reduce to Low risk should be
implemented as soon as practicable.
L LOW RISK Usually acceptable to regulators. Where treatment has
been required to reduce the risk to this level, ongoing
maintenance required.
VL VERY LOW RISK Acceptable. Manage by normal slope maintenance
procedures.
Note: (1) The implications for a particular situation are to be determined by all parties to the risk assessment and may
depend on the nature of the property at risk; these are only given as a general guide.
5.2 Earthworks
5.2.1 Excavation
We understand that the proposed earthworks for the development comprise cutting to depths of up to a
maximum of about 5 m for the basement car park. The toe of the excavation will be setback at least 5 m
from the side boundaries and a minimum of 8 m from the steep dune face. Such excavations should
encounter very loose to loose sand grading to medium dense sand that should be excavatable using
conventional earthmoving equipment.
The sands encountered at this site should stand unsupported at slopes of about 1V:2H in the short-term
provided that groundwater seepage is not encountered and batters are protected from erosion. Given the
boundary setbacks mentioned above, trimming of excavation batters should be achievable at the specified
slopes, however should temporary support be required we understand that sheet piles are the preferred
shoring method.
The use of sheet piles would require consideration of the impact from vibrations on adjacent structures and
underground services. It is recommended that pre-drilling be undertaken to prevent vibration impacts from
sheet piling. A dilapidation survey of adjoining structures and pavements should be carried out prior to sheet
piling. It would be prudent to conduct vibration monitoring, at least during the initial stages of sheet piling, to
confirm the vibration impacts.

LOTS 5 TO 8, SETTLERS COVE, SERENITY CLOSE, NOOSA Section 5.4 below provides advice and design parameters for retaining structures, however detailed design and construction advice should be obtained from a specialist contractor. This should include potential impact on adjacent buildings and services. Design drawings provided by Tate indicate that a ‘working platform’ comprising a minimum 150 mm thick layer of CBR15 material will be placed across the building area following bulk earthworks and compacted to 95% of the Maximum Standard Dry Density. Furthermore, the drawings indicate that assessment of the subgrade shall be carried out by DCP testing following construction of the working platform. 5.2.2 Filling The sand materials excavated from the site should be suitable for re-use as structural fill, provided any deleterious and/or organic materials are excluded. Fill should be compacted at moisture contents within the range of -2% to +1% of optimum moisture content for Standard Compaction. Select fill should have a maximum particle size of 100 mm for an uncompacted layer thickness of 200 mm and should be compacted by repeated rolling to achieve a dry density ratio of at least 95% of the Maximum Standard Dry Density for cohesive soils, or 75% Dry Density Index (DDI) for cohesionless soils. Further details for control and testing of fill are given in Australian Standard AS 3798-1996 "Guidelines on Earthworks for Commercial and Residential Developments". Our experience in similar ground conditions indicates that the achievement of 75% DDI in ‘clean’ dune sands will require the application of significant water and vibration, together with confinement of the layer under compaction. 5.3 Footings The results of our investigation indicate that medium dense (or denser) natural sands occur below about 0.4 m to 2.3 m depth across the site. Given the depth of the proposed basement excavation, such sands should occur across the building subgrade level following bulk earthworks. Conventional high level strip or pad footings may be used where there is a medium dense sand foundation. Strip or pad footings founded in the medium dense sand may be designed using an allowable bearing capacity of 200 kPa, with resultant settlements less than 25 mm. Golder Associates should carry out inspection and testing of the foundations during construction in order to confirm the allowable bearing capacity. All footings should found such that they are not adversely affected by any adjacent excavations batter slopes, trenches, or retaining walls that are not designed to support building loads. To minimise the potential for any adverse interaction effects, footings should found at least below a plane extending 1 m horizontally from the base of trenches/batter slopes/excavations/retaining walls, then rising up at 1V:2H, as illustrated in the following diagram.

If any soil conditions encountered during excavations or piling are found to differ from those noted in the
geotechnical investigation, Golder Associates should be notified immediately, and an inspection carried out
to determine if changes to design are required.
5.4 Retaining Structure Design
The design of any retention system for this site should be conducted with due consideration of embedded
depth below the excavation level (ie. cantilever for sheet piles), variability in stratigraphy over the anchor
embedment length and anticipated ground conditions. Temporary support design must also take into
account the position of adjoining building foundations and underground services. It would be necessary to
gain permission from adjacent site owners and Noosa Council to install anchors below ground level into
adjoining properties.
Retaining structure design may be carried out using a triangular pressure distribution applicable to the wall
type (ie. active pressures for a cantilever wall or at rest pressures for a propped/anchored wall) and based
on the parameters in Table 3. The values in Table 3 assume that the walls are fully drained and no
allowance is included for construction loading, adjacent foundation loadings, the effect of sloping ground, or
backfill compaction stresses.

5.5 Pavements
The design of pavements (flexible and rigid) is based upon the CBR value of the subgrade material. The
subgrade CBR may be obtained by i) laboratory soaked CBR tests, ii) correlations with DCP tests, and iii) the
Queensland Transport Pavement Design Manual – 1990 which provides presumptive insitu CBR values
based on soil type and site conditions.
At this site, the subgrade material is expected to be natural loose to medium dense silty sand/sand and/or
future fill. Section 5.3.3, Table 5.5 of the Queensland Transport Pavement Design Manual, suggests the
CBR values in Table 4 for various subgrade soil types and site conditions.
Table 3: Presumptive CBR Values
Subgrade Type Drainage conditions Presumptive CBR (%)
Silty Sand/Sand Poor 7
Good 10
For this site, we recommend that a preliminary design CBR of 10% be adopted for pavement design within
the anticipated subgrade. The subgrade CBR must be confirmed by DCP testing following earthworks
and/or excavation to subgrade level.
5.6 Drainage
Drainage should be designed to direct water away from building walls and footings. Waters collected from
hard surface (eg. terraces and paved areas) should be directed to the Council stormwater system along the
road frontage. Subsurface disposal of stormwater via RIPs with outlets at least 2 m below the ground
surface is not recommended within 5 m of the crest of the slopes in the western part of the site as shown on
Figure No. 1. The stormwater collection and disposal system should be designed by a hydraulic engineer.

Rapid penetration possible with little effort from the equipment used. M Medium resistance. Excavation/possible at an acceptable rate with moderate effort from the equipment used. H High resistance to penetration/excavation. Further penetration is possible at a slow rate and requires significant effort from the equipment. R Refusal or Practical Refusal. No further progress possible without the risk of damage or unacceptable wear to the digging implement or machine. These assessments are subjective and are dependent on many factors including the equipment power, weight, condition of excavation or drilling tools, and the experience of the operator. WATER Ww Water level at date shown <J Partial water loss Cc Water inflow <4 Complete water loss GROUNDWATER NOT The observation of groundwater, whether present or not, was not possible due to drilling OBSERVED water, surface seepage or cave in of the borehole/test pit. GROUNDWATER NOT The borehole/test pit was dry soon after excavation. However, groundwater could be ENCOUNTERED present in less permeable strata. Inflow may have been observed had the borehole/test pit been left open for a longer period.
