contract. A design working group was developed by the client, and included representatives of the client, state and territory governments and other external stakeholders.

Weekly meetings were held during the design stage to ensure that the design was both practical and safe to build and operate. An independent reviewer was engaged by the client to audit and certify all work performed by the design working group.

Monthly design reports were required, documenting (among other things) the safety aspects of the design. Members of the design working group were located on-site during the construction work and were able to be directly involved. All subcontractors were required to submit a safety plan describing how they would manage safety in the project. These plans were reviewed by the client, with input from the design and construct team.

Example 2: Construction Hazard Assessment Implication Review
A company managing a multi-million dollar construction project made design changes to improve safety after conducting a risk assessment using the CHAIR[1] (Construction Hazard Assessment Implication Review). They included:
    * corridors widened for safer access for movement of goods and people during construction which in turn aided the end users of the building
    * standard doors enlarged by 25 per cent to improve access for equipment
    * lighting repositioned to allow for easier/safer maintenance access
    * windows changed to a 'flip over' style for cleaning from within the building
    * air conditioners moved to ground level, with the ducts remaining in the originally planned position.

Example 3: Lightweight air distribution ductwork
The use of pre-insulated ductwork in a large nursing home project has assisted in the labour intensive installation process that took place in the congested roof spaces and ceiling cavities. The lightweight ductwork was only 15% of the weight of traditional sheet metal ductwork and could be easily handled by a single worker without the need for mechanical lifting equipment.
As the material was already insulated there was no need to for the ductwork to be lagged, as would have been the case with metal ductwork, resulting in a considerable saving in time and
in the need for workers to manipulate mineral fibre insulation in already congested spaces.

Eliminating the need for mineral fibre insulation also eliminated the possible introduction of fibres into the ducting system should there be a leakage in a joint. This also means that the ductwork could be located some 200mm higher in a false ceiling.

The reduced time taken in installation meant that fewer workers were required on-site and that they worked at height for a minimum amount of time.

Example 4: Use of 3 dimensional (3D) modelling as a tool for designers
A building designer had traditionally used sketches and 2D drawings
