1. INTRODUCTION

Geotesta was engaged by The Bathla Group to conduct a geotechnical investigation at

137 South Street, Marsden Park, NSW 2765. The proposed development includes low

density residential developments.

The field work was carried out on 14 Aug 2019. This report presents the geotechnical

investigation results including sub-surface soil profile with interpreted geotechnical

properties of the assessed subsurface lithology, chemical analysis in relation to salinity

and aggressivity, site classification based on AS2870 and recommendations on the

design parameters of footing, founding depth, geotechnical parameters including

allowable bearing capacity of shallow footing/slab, shaft friction and end bearing of

deep foundations.

This assessment has been carried out in general accordance with the following

guidelines:

• Australian Standard (AS1726) 2017: Geotechnical Site Investigation

• Australian Standard (AS2870) 2011: Residential Slabs and Footings

• Australian Standard (AS) 3600 (2009), Concrete Structures

• Salinity Code of Practice March 2003 (Amended January 2004)

2. FIELD INVESTIGATION

The investigation involved drilling of a total of four (4) boreholes to the depth of four

meters or refusal and four (4) DCP tests beside the boreholes for the proposed

residential development at 137 South Street Marsden Park NSW 2765. The area

investigated is highlighted in Figure 1 within the red line.

A site plan showing the borehole and DCP test locations is presented in Figure 1.

Borehole drilling was undertaken using a drilling rig PIXY 41T. All boreholes were

drilled using solid flight augering method.

The soil profiles encountered in the boreholes were logged by a Geotechnical Engineer

from Geotesta in accordance with Australian Standard AS 1726-2017. All the field

observations are presented on the borehole logs attached in Appendix A.

3. FINDINGS

3.1 Site Details, Location and Topography

The investigation area is situated in 137 South Street, Marsden Park, NSW 2765. The

site under investigation is located on the south side of South Street and, approximately

50 km (by road) northwest of Sydney CBD. The site location is shown in Figure 1. The

proposed site is occupied by several sheds and one residential one-story dwelling. The

property slopes gently from west to east.

The proposed site is a mixture of residential land with sheds and unoccupied land.

The site is roughly rectangular shape with an area of approximately 9200 m2.

The site lies at an elevation of approximately 21.5 metres above sea level (ASL)

referenced to Australian Height Datum (AHD) (http://en-au.topographic-map.com).

The site is within the Blacktown City Council.

3.2 Geology

The geological origin of the soil profile was identified from our visual examination of

the soil samples, geotechnical experience, and reference to geological maps of the area.

The geological map of the area indicates that the site is underlain by shale,

carbonaceous, claystone, claystone laminate, fine to medium grained lithic sandstone,

rare coal and tuff of the Wianamatta Group (Pernrith, 1:100000 Geological Sheet, 9030).

3.4 Site Classification

After considering the area geology, the soil profile encountered in the bores; the site is

classified as CLASS ‘M’ with respect to foundation construction (Australian Standard

2870-2011 Residential Slabs and Footings). It is assumed that the founding depth is on

the natural ground.

It has been estimated that the Characteristic Surface Movement (ys) of the underlying

natural soil material will be in the range of 20-40mm provided the building site is

protected from “abnormal moisture conditions” and is drained as described in AS

2870.

It must be emphasized that the heave mentioned, and recommendations referred to in

this report are based solely on the observed soil profile observed at the time of the

investigation for this report, without taking into account any abnormal moisture

conditions as defined in AS2870 – 2011, Clause 1.3.3 that might be created thereafter.

With abnormal moisture conditions, distresses will occur and may result in “non-

acceptable probabilities of serviceability and safety of the building during its design

life,” as defined in AS2870-2011, Clause 1.3.1. If these distresses are not acceptable to

the builder, owner or other relevant parties then further fieldwork and revised footing

recommendations must be carried out.

3.5 Groundwater

Groundwater was not encountered in any of the boreholes.

3.6 Geotechnical Laboratory Testing

Three (3) representative soil samples were sent to Geotesta NATA accredited

laboratory for testing of index properties. The laboratory test results are summarised

in Table 2.

3.7 Laboratory Testing and Analysis–Salinity and Aggressivity

In addition to four boreholes drilled by drilling rig, six more boreholes were drilled by

hand auger to the maximum depth of 0.5m. A total of ten (10) soil samples were

submitted to Eurofin MGT Laboratory, a NATA accredited laboratory, for chemical

testings. The testings were carried out for salinity/aggresivity classification and to

assess exposure classification for the proposed development.

Sampling was targeted to achieve a representative coverage of site conditions in line

with assessed sub-surface profiles, proposed development, and the investigation

scope. Laboratory test certificates are presented in Appendix B.

Guidelines (Table 6.1), a multiplication factor of 14 and 9 were applied to sandy loam and clay loam 2Based on Table 6.2 of Department of Land and Water Conservation (2002) where ECe < 2dS/m = Non-

saline; ECe= 2-4dS/m = slightly saline; ECe = 4-8dS/m = moderately saline; ECe = 8-16dS/m = very saline;

ECe > 16dS/m = highly saline.

Referring to the above test results the site is considered non-saline to very saline.

3.10 Exposure Classifications for concrete in Saline and sulfate soils

The site soil is considered none-saline to very saline and Non-aggressive to mild-

aggressive to concrete. An exposure classification of A2 for concrete in saline soils and

an exposure classification of A2 for concrete and steel in sulphate soils should be

adopted for preliminary design of proposed concrete structures.

In addition to the saline soil management strategies to be required for this site, we

recommend design of new structures should consider the following minimum

requirements: • Limiting soil disturbance, such as cut and fill, so saline or sodic subsoils are not exposed,

or groundwater is not intercepted.

• Using exposure grade bricks/masonry below damp course or in retaining walls.

• Providing concrete strength and cover to steel reinforcing in accordance with AS 3600

(2009) and the exposure classifications outlined above.

• Limiting excess surface water infiltration into the soil by designing, installing and

maintaining appropriate stormwater drainage (gutters, downpipes, pits and pipes).

• Further assessment including laboratory testing, to improve characterisation of site

salinity conditions, particularly in proposed development areas, and assess potential

ensuing implications on the proposed development and mitigation requirements

4.2 Strip/Pad Footing System

It is recommended that an engineer designed strip/pad footing system for a Class M site be

used on this site except. We recommend that the designing engineer refer to AS2870-2011 to

ensure design compliance to this document.

The strip footings should be founded in the natural soil layer and penetrate through any fill

material, tree roots and founded at least 100mm into the recommended founding material. As

a guide with information obtained from the bores and DCP tests, the actual founding depth

for strip/pad footings at the test locations should be as follow:

The founding depth should be as stipulated above or to hard layer, whichever is encountered

first. It should be noted that the soil profile may vary across the site. The foundation depths

quoted in this report are measured from the surface during our testing and may vary

accordingly if any filling or excavation works are carried out. It is recommended that a

geotechnical engineer be engaged during footing excavation stage to confirm the founding

depth and founding material.

4.3 Slab on Ground

It is recommended that an engineer designed slab on ground footing system for a Class M site

be used on this site. We recommend that the designing engineer refer to AS2870-2011 to

ensure design compliance to this document.

The edge and load bearing beams for the slab footings should be founded in the natural soil

layer and penetrate through any fill material, tree roots and founded at least 100 mm into the

recommended founding material. As a guide with information obtained from the bores and

DCP tests the actual founding depth for edge and load bearing beams at the test locations

should be as follows:

It should be noted that the soil profile may vary across the site. The foundation depths quoted

in this report are measured from the surface during our testing and may vary accordingly if

any filling or excavation works are carried out. It is recommended that a geotechnical engineer

be engaged during footing excavation stage to confirm the founding depth and founding

material.

Slab panels and internal beams can be founded in the natural soil profile or in compacted

surface filling and/or as required in the design by engineering principles. Compacted filling

used to raise levels beneath panels must be placed and compacted as per specifications for

controlled or rolled fill.

Controlled fill is material that has been placed and compacted in layers by compaction

equipment within a defined moisture range to a defined density requirement. Except as

provided below, controlled fill shall be placed in accordance with AS 3798.

If more than 400mm of CLAY FILL or 800mm of SAND FILL, imported or site derived,

including existing FILL material, is required, then the slab must be designed as a suspended

slab and supported by a grid of beams founded through any fill material in accordance with

the above edge beam recommendations.

4.4 Bored Piers or Screw Piles

Bored piers or Screw piles can be used to support the proposed residential units. The

pier/pile foundation of the proposed structure is assumed to be a high redundancy

system and the intrinsic test factor (фtf) is assumed to be equal to basic geotechnical

strength reduction factor (фgb), in accordance to AS2159-2009. The overall design

average risk rating (ARR) is to be calculated by the designer and the corresponding

geotechnical strength reduction shall be adopted.

4.4.1 Pile Construction Considerations

Where necessary and appropriate, at contractor’s discretion, a temporary casing may be used

to prevent the pile excavation from collapsing. The inside of the casing must be clean and free

of any projections (such as weld backing bars) which could be an obstacle to the placing and

positioning of the reinforcement cage for the piles. Temporary casings may be left in place

provided that the minimum socket length is not cased and the minimum cover to

reinforcement is maintained. Where a casing is left in place, gaps between the casing and the

sides of excavations shall be filled with sand and compact the sand by flooding. In the case of

piles subject to high lateral loads (e.g. abutment piles and anchor pier piles), fill such gaps with

a cementitious grout containing fine aggregates proportioned to produce a pourable liquid

without segregation, with a compressive strength at 28 days not less than 10MPa when

sampled and tested to Test Method RMS T375. Cement used for the grout must conform to

Specification RMS 3211.

5. EXCAVATION, RETAINING WALL & LATERAL EARTH

PRESSURES

5.1 Temporary Cut Batter and Excavation

Excavation in the stiff to hard clay can be undertaken to 3m depth with 1V:2H batter.

The above recommendation assumes that there is no existing structure adjacent to the

excavation area. Even at the above cut batters it should be noted that following rainy

periods, some degree of fretting and minor slumping could be anticipated.

The batter slope angle is recommended subjected to the following measures:

• The batters should be protected against erosion

• Permanent batters should be drained

• Temporary batters shall not be left unsupported for more than 2 months without

further advice. Following heavy rains (raining more than 6 hours with the

intensity of greater than 15mm/day) should be inspected by a geotechnical

engineer.

• An offset distance of 1.5m from the batter crest should be maintained for the

loads.

Soft and Intermediate excavation condition is expected in clay and shale respectively.

The table below describes the excavation classes as per SANS 1200D.

Table 9: Excavation classes as per SANS 1200D

Excavation Class Description

Soft Excavation in material that can be efficiently removed by a back-acting excavator

of flywheel power approximately 0.10kW per millimetre of tined-bucket width,

without the use of pneumatic tools such as paving breakers

Intermediate Excavation in material that requires a back-acting excavator of flywheel power

exceeding 0.10 kW per millimetre of tined-bucket width or the use of pneumatic

tools before removal by equipment equivalent to that specified for soft excavation.

Hard Hard rock excavation shall be excavation in material (excluding boulder

excavation) that cannot be efficiently removed without blasting or wedging and

splitting.

5.2 Retaining Walls

Any proposed retaining walls at the site should be engineer designed adopting the

geotechnical parameters summarised in Table 5 above.

For construction methods which minimise deflection and where restraint is applied via struts,

bracings or anchors, the temporary or short-term lateral earth pressure distribution should be

approximated as a trapezoidal distribution behind the retaining wall. A maximum lateral earth


14

pressure of 8H kPa is obtained at a depth of 0.25H, and where H is the total depth of the

excavation to be retained. For basement walls where wall deflections are not critical, the

maximum lateral earth pressure may be reduced to 6H kPa.

It must be emphasised that where adjoining footings exist near the retaining walls, the “at rest”

earth pressures must be maintained, and the active design condition is not appropriate.

5.3 Basement Construction

In the event of rising ground water, under-slab drainage should be provided to the pit to

prevent hydrostatic build-up.

Preparation of the basement floor subgrade should consist of stripping to grade and proof

rolling the subgrade, ensuring that any localized soft spots are removed and made good with

clean granular filling compacted to a dry density not less than 98% of the maximum dry

density value determined by the Standard Compaction test in accordance with Australian

Standard AS1289 5.1.1 -2017.

Information about This Report

The report contains the results of Soil and water quality Assessment conducted for a specific

purpose and client. The results should not be used by other parties, or for other purposes, as

they may contain neither adequate nor appropriate information.

Test Hole Logging

The information on the test hole logs (boreholes, test pits, exposures etc.) is based on a visual

and tactile assessment, except at the discrete locations where test information is available (field

and/or laboratory results). The test hole logs include both factual data and inferred

information.

Groundwater

Unless otherwise indicated, the water levels presented on the test hole logs are the levels of

free water or seepage in the test hole recorded at the given time of measuring. The actual

groundwater level may differ from this recorded level depending on material permeability

(i.e. depending on response time of the measuring instrument). Further, variations of this level

could occur with time due to such effects as seasonal, environmental and tidal fluctuations or

construction activities. Confirmation of groundwater levels, pheratic surfaces or piezometric

pressures can only be made by appropriate instrumentation techniques and monitoring

programmes.

Interpretation of Results

The discussion or recommendations contained within this report normally are based on a site

evaluation from discrete test hole data. Generalised, idealised or inferred subsurface

conditions (including any geotechnical cross-sections) have been assumed or prepared by

interpolation and/or extrapolation of these data. As such these conditions are an interpretation

and must be considered as a guide only.

Change in Conditions

Local variations or anomalies in the generalised ground conditions do occur in the natural

environment, particularly between discrete test hole locations. Additionally, certain design or

construction procedures may have been assumed in assessing the soil-structure interaction

behaviour of the site. Furthermore, conditions may change at the site from those encountered

at the time of the geotechnical investigation through construction activities and constantly

changing natural forces.

Any change in design, in construction methods, or in ground conditions as noted during

construction, from those assumed or reported should be referred to GEOTESTA for

appropriate assessment and comment.

Reproduction of Reports

Where it is desired to reproduce the information contained in our geotechnical report, or other

technical information, for the inclusion in contract documents or engineering specification of

the subject development, such reproductions should include at least all of the relevant test

hole and test data, together with the appropriate standard description sheets and remarks

made in the written report of a factual or descriptive nature. Reports are the subject of

Sample HistoryWhere samples are submitted/analysed over several days, the last date of extraction and analysis is reported.A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However,no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results.

If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.

QC - Acceptance Criteria

QC Data General Comments

1. Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples follows guidelines delineated in the National Environment Protection (Assessment of Site

Contamination) Measure 1999, as amended May 2013 and are included in this QC report where applicable. Additional QC data may be available on request.

2. All soil/sediment/solid results are reported on a dry basis, unless otherwise stated.

3. All biota/food results are reported on a wet weight basis on the edible portion, unless otherwise stated.

4. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences.

5. Results are uncorrected for matrix spikes or surrogate recoveries except for PFAS compounds.

6. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise.

7. Samples were analysed on an 'as received' basis.

8. Information identified on this report with blue colour, indicates data provided by customer, that may have an impact on the results.

9. This report replaces any interim results previously issued.

Please refer to 'Sample Preservation and Container Guide' for holding times (QS3001).

For samples received on the last day of holding time, notification of testing requirements should have been received at least 6 hours prior to sample receipt deadlines as stated on the SRA.

If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues, suitably qualified results may still be reported.

Holding times apply from the date of sampling, therefore compliance to these may be outside the laboratory's control.

For VOCs containing vinyl chloride, styrene and 2-chloroethyl vinyl ether the holding time is 7 days however for all other VOCs such as BTEX or C6-10 TRH then the holding time is 14 days.

**NOTE: pH duplicates are reported as a range NOT as RPD

mg/kg: milligrams per kilogram mg/L: milligrams per litre ug/L: micrograms per litre

ppm: Parts per million ppb: Parts per billion %: Percentage

org/100mL: Organisms per 100 millilitres NTU: Nephelometric Turbidity Units MPN/100mL: Most Probable Number of organisms per 100 millilitres

Dry Where a moisture has been determined on a solid sample the result is expressed on a dry basis.

LOR Limit of Reporting.

SPIKE Addition of the analyte to the sample and reported as percentage recovery.

RPD Relative Percent Difference between two Duplicate pieces of analysis.

LCS Laboratory Control Sample - reported as percent recovery.

CRM Certified Reference Material - reported as percent recovery.

Method Blank In the case of solid samples these are performed on laboratory certified clean sands and in the case of water samples these are performed on de-ionised water.

Surr - Surrogate The addition of a like compound to the analyte target and reported as percentage recovery.

Duplicate A second piece of analysis from the same sample and reported in the same units as the result to show comparison.

CP Client Parent - QC was performed on samples pertaining to this report

NCP Non-Client Parent - QC performed on samples not pertaining to this report, QC is representative of the sequence or batch that client samples were analysed within.

TEQ Toxic Equivalency Quotient

RPD Duplicates: Global RPD Duplicates Acceptance Criteria is 30% however the following acceptance guidelines are equally applicable:

Results <10 times the LOR : No Limit

Results between 10-20 times the LOR : RPD must lie between 0-50%

Results >20 times the LOR : RPD must lie between 0-30%

Surrogate Recoveries: Recoveries must lie between 20-130% Phenols & 50-150% PFASs

PFAS field samples that contain surrogate recoveries in excess of the QC limit designated in QSM 5.3 where no positive PFAS results have been reported have been reviewed and no data was

affected.

WA DWER (n=10): PFBA, PFPeA, PFHxA, PFHpA, PFOA, PFBS, PFHxS, PFOS, 6:2 FTSA, 8:2 FTSA

1. Where a result is reported as a less than (<), higher than the nominated LOR, this is due to either matrix interference, extract dilution required due to interferences or contaminant levels within

the sample, high moisture content or insufficient sample provided.

2. Duplicate data shown within this report that states the word "BATCH" is a Batch Duplicate from outside of your sample batch, but within the laboratory sample batch at a 1:10 ratio. The Parent

and Duplicate data shown is not data from your samples.

3. Organochlorine Pesticide analysis - where reporting LCS data, Toxaphene & Chlordane are not added to the LCS.

4. Organochlorine Pesticide analysis - where reporting Spike data, Toxaphene is not added to the Spike.

5. Total Recoverable Hydrocarbons - where reporting Spike & LCS data, a single spike of commercial Hydrocarbon products in the range of C12-C30 is added and it's Total Recovery is reported

in the C10-C14 cell of the Report.

6. pH and Free Chlorine analysed in the laboratory - Analysis on this test must begin within 30 minutes of sampling.Therefore laboratory analysis is unlikely to be completed within holding time.

Analysis will begin as soon as possible after sample receipt.

7. Recovery Data (Spikes & Surrogates) - where chromatographic interference does not allow the determination of Recovery the term "INT" appears against that analyte.

8. Polychlorinated Biphenyls are spiked only using Aroclor 1260 in Matrix Spikes and LCS.

9. For Matrix Spikes and LCS results a dash " -" in the report means that the specific analyte was not added to the QC sample.

10. Duplicate RPDs are calculated from raw analytical data thus it is possible to have two sets of data.

Qualifier Codes/Comments

Code Description

N01F2 is determined by arithmetically subtracting the "naphthalene" value from the ">C10-C16" value. The naphthalene value used in this calculation is obtained from volatiles(Purge & Trap analysis).

N02

Where we have reported both volatile (P&T GCMS) and semivolatile (GCMS) naphthalene data, results may not be identical. Provided correct sample handling protocols havebeen followed, any observed differences in results are likely to be due to procedural differences within each methodology. Results determined by both techniques have passedall QAQC acceptance criteria, and are entirely technically valid.

N04F1 is determined by arithmetically subtracting the "Total BTEX" value from the "C6-C10" value. The "Total BTEX" value is obtained by summing the concentrations of BTEXanalytes. The "C6-C10" value is obtained by quantitating against a standard of mixed aromatic/aliphatic analytes.

N07Please note:- These two PAH isomers closely co-elute using the most contemporary analytical methods and both the reported concentration (and the TEQ) apply specifically tothe total of the two co-eluting PAHs
