Although your configuration may meet all the criteria, our guidance is – What does your Customer want? TG20:08 is very specific and prescriptive in the requirements of scaffolds which can be erected without further design such as where they are, the wind load on them, a maximum of 2m bays, a maximum of 2m lifts and whether they are netted or sheeted etc. Unfortunately this has added to the confusion. In addition to this, it reproduces a number of design tables from which the intention is certain configurations of scaffold, if meeting the configuration arrangement, do not require any further design. TG20:08 attempts to interpret the requirements of BS and provides guidance notes for good practice in the design and erection of scaffolds. ‘TG20:08 A guide to good practice for Scaffolding with Tubes & Fittings’ is a document derived from ‘BS EN 12811 Temporary Works equipment – Scaffolds’ – the British Standard for the design and erection of scaffolds. Confusion arises from the existence of TG20 guidance documents and historical practice within the industry.
