1 INTRODUCTION
Arcos Unit Group Pty Ltd (Arcos) was commissioned to undertake a geotechnical investigation for the
proposed residential development located 2/27 Ross Crescent, Sunshine Beach.
It is understood that the proposed development will comprise a new garage and guest pavilion (two-storey) as
well as a standalone home office. The two-storey addition will also include a lift. Bulk earthworks comprising
cuts of up to approximately 1.8 m are anticipated as part of the works.
This report outlines the results of the investigation, analysis, and interpretive reporting on the following items:
•   All factual information resulting from the investigation (investigation methodologies, desktop review, test
    location plans, bore logs);
•   Summary of subsurface conditions and adopted subsurface conditions including groundwater;
•   Earthworks and site preparation comments;
•   Foundation soil reactivity in accordance with AS2870;
•   Foundation options and design parameters;
•   Geotechnical retaining wall design parameters;
•   Slope stability assessment in accordance with AGS Guidelines; and
•   Construction constraints and risks (if any) from a geotechnical context.
This report can only be used and relied upon under our terms and conditions of engagement. The report cannot
be separated for any reason or redistributed without our written authority.



2 SITE DESCRIPTION
The site is located at 2/27 Ross Crescent, Sunshine Beach and is described as Lot 2 on GTP100987. The site
is broadly rectangular in shape and is occupied by an existing terraced dwelling. The terraces are supported
by a series of rock grouted and boulder retaining walls. The remainder of the site is moderately vegetated with
shrubbery and semi-mature trees measuring up to approximately 5-10 m high. Topographically, the site falls
towards the coastline in the east at grades at between 20˚ and 30˚.
