Safety in Design (SiD) means the integration of control measures as early as possible in the design process to eliminate or, if this is not reasonably practicable, minimise risks to health and safety throughout the life of the infrastructure being designed
The safe design of infrastructure will always be part of a wider set of design objectives, including practicability, aesthetics, cost and functionality. Sometimes these competing objectives need to be balanced in a manner that does not compromise the health and safety of those who work on or use the infrastructure over its life.
Safe design begins at the concept development phase of the infrastructure when making decisions about:
The design and its intended purpose
Materials to be used
Possible methods of construction, maintenance, operation, demolition or dismantling and disposal
What legislation, codes of practice and standards need to be considered and complied with.
For further guidance on Safety in Design requirements for electrical installations and equipment, see Sunshine Coast Council Safety in Design Management – Health and Safety Procedure.
Unless otherwise specified, current relevant Australian Standards are to be observed.
All equipment and materials used shall be new unless otherwise specified.
Works are to be carried out by suitably qualified professionals.

All contractors are to hold current licences required by the relevant authority.
The contractor is to provide a minimum warranty of 12 months for installation under normal working conditions (including plant) from the date of practical completion.
Should the installation or part thereof prove to be defective or fail to fulfil the requirements of this specification, the defective equipment shall be repaired or replaced by the contractor. Any associated costs are to be borne by the contractor.
Council reserves the right to extend the warranty period depending on the project.
See Section 15 Practical completion and defects liability for further guidance.
Measurements and dimensions are minimum requirements. Considerations for substitutions and replacements are to ensure the following:
Alternatives to documented products, methods or systems must be accompanied by sufficient information to permit evaluation prior to approval.
All variations or substitutions are to be approved by the Superintendent prior to commencement. If the substitution is for any reason other than unavailability, submit evidence that the substitution is:
Of net enhanced value to the project.
Consistent with the project drawings and is as effective as the identified item, detail or method.
Any non-preferred equipment must be reviewed by council prior to specification and/or commencement of installation. Failure to do so may result in rejection of equipment and rectification of defect.
Any specialist equipment required to maintain electrical installation, e.g. cherry picker, is to be included in the tender/construction cost. No variation will be accepted for equipment hire during the maintenance period.
A Safety Data Sheet (SDS), previously called a Material Safety Data Sheet, is a document containing important information about a hazardous chemical which may be identified as both a hazardous substance and/or a dangerous good. The SDS provides health and safety representatives, employers, self-employed persons and workers with the necessary information to safely manage the risk from hazardous substance exposure.
Council requires the following:
A current SDS be readily available in paper form for all substances that may be transported on a work vehicle and at sites where work is to be undertaken.

During their nesting/breeding period, turtles may be easily disturbed by light, noise and movement. This may cause confusion, disorientation and possible death for turtle hatchlings and nesting females.
Ultimately, nesting turtles will avoid beaches with light pollution. In order to conserve turtle nesting on the Sunshine Coast, light pollution in coastal areas should be minimised.
Lighting and other infrastructure must be installed to ensure minimal interference with potential turtle paths in known turtle nesting areas.
Turtle nesting occurs on all beaches in the Sunshine Coast area.
Typically, turtles will not nest from Mooloolaba to Maroochydore and the Kings Beach area due to existing light pollution.
Council will advise which beaches these are on a project dependent basis.
Any lighting within these zones must be turtle friendly. This includes:
Minimise use of white lights that emit ultraviolet light
Amber (550 nm - 700 nm as per EPA guidelines) or monochromatic light.
Light guards are to be installed to direct spill light away from turtle nesting areas.
Positioning lights so they face away from the beach.
Mount light fixtures as low as possible to minimise light spill.
Reduce the light footprint by using distribution types that illuminate along rather than across roadways.
For further guidance on turtle friendly lighting, see LIM Electrical.
