RFI - Attachment C - Civil Engineering Report

31 May 2019


The changes to Hoffman Drive have been addressed from a traffic perspective in the Traffic Impact
Assessment lodged under separate cover.
All external roadworks will be designed in accordance with Noosa Council and Austroads requirements.

The site’s access will be off the existing driveway within the easement for site access for staff, visitors
and service vehicles. A drop off bay will be constructed adjoining the existing driveway. Minor works to
the existing internal roadway will be required as a result of the development. The roadway changes have
been address in a Traffic Impact Assessment under separate cover.

The proposed internal on-grade and basement car parking layouts are depicted on the architectural
plans prepared by Thomson Adsett Architects attached in Appendix 1.

All loading bays and car parks will be constructed in accordance with the relevant Noosa Shire Council
and Australian Standards.


10         EARTHWORKS
A preliminary levels plan showing the proposed site levels for the on grade car park and building pad is
shown on MPN Plan 7662-DA03 attached in Appendix 3.

Earthworks will also be undertaken on site for the construction of the basement car parking.
Any shoring design for the proposed basement will be undertaken at the detail design stage of the
development. The shoring will be designed and RPEQ certified to ensure that the neighbouring buildings
are supported during both the construction phase and the operational phase. All shoring will be fully
contained within the development site.

An Acid Sulfate Soils investigation has been completed for the site and is lodged under separate cover.
The investigation noted that the high level soils are naturally slightly acidic with the underlying sandy
clays likely to be actual acid sulfate soils. The report provides a treatment requirement and
methodology which will be adhered to during the construction process.

The design and construction of earthworks will be in accordance with the recommendations of a
geotechnical report along with AS 3798 – Guidelines on Earthworks for Commercial and Residential
Developments. Any excavated material not suitable for fill will be removed from the site and disposed of
appropriately in an approved landfill.



11         ELECTRICITY AND TELECOMMUNICATIONS
The proposed development will be serviced for electricity and telecommunications services from the
existing underground and overhead infrastructure. The electrical and telecommunications services will
be extended into the site to provide the required level of service. All works will be undertaken in
accordance with the relevant authority’s requirements.

The existing Energex and NBN infrastructure in the vicinity of the site is shown on the Energex and NBN
DBYD Plans attached in Appendix 4.



12         GAS
There is no existing gas infrastructure in the vicinity of the site.
