Dear Sir

RE: GEOTECHNICAL INVESTIGATION —- PROPOSED RESIDENTIAL CONSTRUCTION
71 SEAVIEW TERRACE, SUNSHINE BEACH

1.0 INTRODUCTION

This report records the results of an investigation of the ground conditions on the site located
at the northern end of Seaview Terrace at Sunshine Beach which shares a common boundary
with the Noosa National Park.

The proposed residence is located on the upper slopes of the allotment, close to the western
boundary. It is of two living levels at RL44.0m (AHD) and RL39.5m, with gardens at about
these levels outside the living areas and a deck above at RL47.50m to RL50.0m.

Access from a Seaview Terrace laneway extension reaches the boundary at about RL50.0m
AHD. Benched excavations are proposed below the existing slope to form the building
platforms. The investigation aim is to define the ground conditions for the structure support
and for the support on the excavation lines.
Advice and recommendations relating to the following have been provided in this report:-

e Stability of cut banks and retaining wall design parameters

e Groundwater depths

e Load bearing ability of soils

e General earthworks recommendations

e Footings — shallow foundations or piling support (piling depth and piling type)

according to Australian standard AS 2159 — 1995 Piling Design and installation

Drilling and sampling on the site proceeded through 21 to 25" September 2009 with the
approval of the owner Mr A Slinger.

Reference has been made to a previous soil test, slope stability and footing report conducted
by SCG Consulting Engineers. Their report dated 24"" March 2009 [ref No. 19064(S)] refers.
