Acid Sulfate Soils Letter
Proposed Residential Development
25 Wyuna Drive, Noosaville

At the request of SCG Engineering Holdings Pty Ltd (SCG)PTG Consulting (PTG) have reviewed Noosa
Council's request for information with respect to OPW24/0089 dated 29 July 2024 for the above-mentioned
address and provide response to the engineering related items.

Issue:
The submitted Geotechnical Investigation Report does not fully address the potential for acid
sulfate soils or groundwater and section 8 of the report provides preliminary comments only.

 

Information Required:
Provide an amended Geotechnical Investigation Report that includes site specific recommendations to
address/control the sites potential for acid sulfate soils (ASS) and groundwater.

Response:
The geotechnical investigation Report: PTG/00259 - 0001 - Revi dated 11 July 2024 was submitted which

includes preliminary ASS commentary though notes that based on the proposed level of disturbance, three
additional boreholes to 4 m depth are required to meet the requirements of the Queensland Acid Sulfate Soils
Technical Manual (QASSTM). The boreholes should be appropriately spread across the site.

Due to access restrictions on the site caused by the existing house, drilling rig access is not available to gain
an appropriate spread across the site. Additionally, hand auger equipment is not considered suitable due to
the depth required to be sampled. Therefore, it is recommended that the additional investigations be carried
out post demolition in order to appropriately meet the QASSTM requirements

We trust this information is satisfactory for your current needs. Should you have any questions, please feel
free to contact the undersigned.

Regards,

PTG Consulting
