scaffolds that require specific engineering designs, such as hung scaffolds, cantilevered scaffolds, loading platforms, birdcage scaffolds or scaffolds where the loads from one bay are transferred to the adjoining standards, eg spur scaffolds or scaffolds incorporating an access opening.There may be prefabricated modular steel scaffolding designs (component or site-specific configuration) that require specific erection methods. This guide covers the erecting, altering and dismantling of prefabricated steel modular scaffolding founded on the ground or another solid surface.įully decked scaffolds over 20 m in height may exceed the design strength of the system and the design should be verified by the manufacturer, supplier or an engineer competent in scaffold design. In such instances alternative safe work methods must be developed to provide an equivalent level of safety. If the work activity or building design prevents fully planked platforms at 2 m intervals, eg a façade or building profile that requires the working platforms to be more than 2 m intervals for the work to be carried out – a larger interval up to 3 m may be used.įor some applications the configurations of the structure or equipment for which the scaffolding is to be installed makes it not practicable to follow the principle of installing fully planked platforms at 2 or 3 m vertical intervals. The fully planked platforms are to remain in place until the scaffold is dismantled.

To minimise these risks, this guide requires scaffolders to install and work from fully planked platforms at vertical intervals of between 2 and 3 m (2 m where practicable), and to install guardrails and mid-rails in advance of the decking. There are risks associated with scaffolders falling through and from the scaffold. These concepts should be incorporated into scaffolding manufacturer or supplier information, and erectors’ safe work method statements. The concepts within this guide differ from traditional scaffold erection methods, which are no longer considered acceptable. However, ‘Appendix A – Scaffold design limitations’ only applies to prefabricated steel modular scaffolding. While steel is the dominant material used in the manufacture of prefabricated modular scaffolding, the concepts and procedures in this guide also apply to prefabricated modular scaffolds manufactured from other materials. The purpose of this guide is to provide guidance to the scaffolding industry to safely erect, alter and dismantle prefabricated steel modular scaffolding for commercial and residential buildings. Following this guide is a means to achieve such compliance.
Work health and safety regulations require the control of risk to health and safety. This guide has been developed in consultation with industry and provides practical guidance for those erecting, altering and dismantling scaffolding, and for principal contractors, employers, suppliers of scaffolds and others involved in using prefabricated steel modular scaffolding.
