5 ENGINEERING ASSESSMENT
5.1 General
An engineering assessment has been undertaken to address the servicing of the proposed
medical development at the corner of Goodchap Street & Val Crescent, Noosaville. The site
currently contains low density residential lots with five existing dwellings which are serviced by
water, sewer, electricity and telecommunications. Following receipt of information regarding
the existing infrastructure within the area, an engineering assessment has been undertaken to
address the servicing of the proposed development.


5.2 Earthworks
The existing residential dwellings will be removed prior to any earthworks being undertaken.
Following the removal of the existing buildings, preliminary earthworks will be undertaken to
provide a level building pad for the basement and ground level construction. All temporary
batters will be constructed a minimum 0.5m in from the property boundary with the maximum
batter slope of 1 in 1 unless otherwise noted in the Geotechnical Investigation to be completed
for detailed design.

The proposed earthworks over the subject site will be carried out under Level 1 geotechnical
supervision as per AS3798 – 2007 “Guidelines on earthworks for commercial and residential
developments”.

As part of the site is located below 5.0m AHD, an assessment of Acid Sulphate Soils (ASS) will be
included within the Geotechnical Investigation. If any ASS are encountered on site they will be
treated and disposed of in accordance with Noosa Council’s Planning Scheme and Best
Management Practice.

Refer to Appendix G for the Noosa Council ASS Overlay Mapping of the Noosaville region.


5.3 Erosion and Sediment Control
The siteworks will be generally contained within the property boundary with some works to be
undertaken within the verge of Goodchap Street in order to provide two driveway crossovers.
Some minor re-grading and excavation along the verge of Val Crescent will be undertaken to
provide an overland flow path from the basement level car park and for the construction of
new service connections.

Any sediment generated during the construction phase shall be dealt with in accordance with
an Erosion and Sediment Control Plan to be prepared by Morgan Consulting Engineers and kept
on site during the construction phase. Erosion and Sediment Control (ESC) Measures such as silt
fences, diversion drains, drainage structure protection and dust control (clearing) will be
implemented. Silt fences are to be erected along the boundary of the site and around the
construction area. These fences are to be cleaned by the contractor when the capacity is
reduced by 25%. Where possible, disturbance to the existing surface is to be limited to the
immediate work area.
