For more information on this you should contact your local HSE office. Practice: Access and working scaffolds and special scaffold structures in steel BS 5973:1981. Until the release of the revised TG20 the HSE continue to allow scaffold to be built in accordance with BS 5973. Width of pavement/gangway outside hoarding/scaffolding. This is the reason for the 'limbo' situation. However, TG20 received a mixed response from the UK industry and as a result TG20 is being re-written and the new version is due for release sometime in 2008. TG20 is largely based on BS 5973 with extracts taken directly from the old code, it also uses permissible stress design method. Therefore the NASC (National Access and Scaffolding Confederation) released a technical guidance called TG20 which aimed to provide a good practice guide for the use of tube and fitting scaffolding whilst conforming to the requirements of BS EN 12811-1. PT Mitra Solusi Optimalindo concern to security aspects by following the provisions of regulations BS-5973: 1973 (British Standard) and AS / NZS 15 (Australian Standards) Tubular Systems Tubular scaffolding systems are highly flexible and can be adapted to nearly every type of complex structure.
The reason for this being that the new BS EN 12811-1 does not lend itself to the use of tube and fitting scaffolding (the majority of scaffolding in the UK is tube and fitting) and also uses a the limit state design method (BS 5973 uses permissible stress design method). 3) The recommended tightening torque range for both the anchor bolt and the coupler.
BS 5973 was the recommended code of practice for around 25 years, however since its withdrawal, and the introduction of BS EN 12811-1:2003, the UK industry has been in limbo. Further advice is contained in BS 5973 and NASC Technical Guidance Note TG4. The Provision and Use of Work Equipment Regulations (1993) also applies. All scaffolds are subject to certain minimum requirements set out in British Standard (BS) 5973 (Withdrawn by the BSI in 2004)- the Code of Practice for Access and Working Scaffolds and Special Scaffold Structures in Steel. National annex NC discusses the aspects of structural design by limit state covered by this standard, but not considered in BS 5973 (withdrawn).
