3.0 PROPOSED DEVELOPMENT a

 

We understand that a staged redevelopment of the existing surf club is proposed, which
is to involve the construction of a 3-storey extension to the east of the existing building, as
part of Stage 1. Stage 2 of the redevelopment is understood to consist of the replacement
of the existing building, which would be carried out at some later date.

It is understood that the ground level of the new extension (Stage 1 Construction) would
be set below the existing ground surface elevation on the northern side, requiring some
excavation. It is estimated that the Stage 1 works would require less than 1,000m? of
excavation.

4.0 G CHNICAL INVESTIGATION
4.1 Site Description —- , _

The existing Noosa Heads SLSC clubhouse is located on the northern/beach side of
Hastings Street, Noosa Heads.

At the time of the investigation the site was occupied by the existing surf clubhouse
building. A grassed and sandy beach area is located to the northern side of the clubhouse
and is separated from the beach by a concrete footpath. A small sand dune is located in
the area of proposed extensions to the east of the clubhouse and is vegetated with grass
and small trees/shrubs. The front of the site is occupied with footpath and carparking
areas along Hastings Street.

Subsurface conditions at the site were investigated by drilling and sampling a total of
three (3) boreholes, consisting of two (2) deep boreholes to depths of 15.0m (BH3) and
20.2m (BH1) for deep profiling to weathered rock for a deep foundation system and one
(1) shallow boreholes to a depth of 2.25m for acid sulfate soi! sampling. The fieldwork
was conducted over three separate days using a track mounted Hydrapower drilling rig
and a truck mounted Gemco HP7 drilling rig.

In-situ testing consisted of standard penetration tests - SPT (Test Method AS.1289 6.3.1)
and pocket penetrometer (PP) testing of undisturbed samples taken using 50mm
diameter thin-wall tubes.
