other designs of the same type of structure.
There may be multiple designers who are involved in the design of a structure and have the same duties, for example draftspersons, architects and engineers. A builder could also be considered to be a designer if they design a structure themselves or are involved in altering the design for a building, even after construction work has commenced.

Example 1 – A builder or subcontractor who alters or modifies a design without consulting the original or subsequent designer assumes the duties of a designer.

Any changes to the design of a structure may affect the health and safety of those who work on or use the structure and must be considered by the person altering or modifying a design.

If new or different health and safety risks are created, further calculations, analysis, testing or examination may be required, and a revised safety report may need to be prepared.

Consulting, co-operating and co-ordinating activities with other duty holders
The design process often occurs in various stages and involves different people who make financial, commercial, specialist or technical decisions over a design, for example, clients, architects, project managers and interior designers.
Such decisions may positively or negatively affect the safety of a building. In these circumstances, each party will have responsibility for health and safety in the design stage.
So far as is reasonably practicable, the duty holders involved must consult each other on the hazards and risks associated with the building and work together on appropriate design solutions. This would include a client co-operating with a designer in changing a design to address a health and safety risk identified in the design process.

Calculation, testing or examination
Designers of structures must carry out, or arrange the carrying out of, any calculations, analysis, testing or examination that may be necessary to ensure the safety of the design.
Depending on qualifications and experience, a designer may not always be aware of construction methods and processes to be applied in practice and should therefore seek feedback from builders about the safe 'buildability' of their design.
Other legislative provisions governing the design of buildings and structures in Australia include
the building laws in each jurisdiction and the National Construction Code of Australia (NCCA).
The Building Code of Australia (BCA) is part of the NCCA. In addition, there are technical and engineering guidelines and standards produced by other government agencies, Standards Australia and relevant professional bodies.
Providing information

Information on how the designer has designed the structure to be without risk to health and safety must be provided to anyone issued with the design documents. This includes the lifecycle of the structure from construction, maintenance, use and demolition at
