Many free-standing scaffolding structures, such as access towers, major signboards, fences and enclosures, need to be anchored to the ground, primarily to resist wind forces. Whilst all structures requiring restraint via anchoring to the ground should be subject to a bespoke design produced by a competent engineer, the guidance considers different types of anchors available and typical indicative holding capacities, the possibility of disturbing underground services, the use of guys and scaffold tube restraint.

This guidance explains the differences between ‘supplementary’ and ‘check’ couplers and gives typical design applications where high coupler forces could be expected and where additional loadbearing capacity to connections may be required. It also contains guidance on coupler configurations and expected safe working loads (SWLs) where supplementary couplers are used. To ensure that SWL values are as accurate as possible, data provided within this document is based on practical testing rather than calculation. 2 pages
A temporary roof or building is a sheeted structure designed to protect the area inside from the effects of weather, dust, etc. This guide is intended to give design and construction information to the suppliers and erectors of temporary roofs and buildings and intended for use by contractors during the building process. 56 pages
When in use, scaffold boards are often subjected to harsh conditions and mistreatment and may deteriorate to such an extent that they become unsafe. To ensure that they remain in a safe and serviceable condition, they should be subjected to regular inspections/checks and where necessary repaired/refurbished to ensure that they remain fit for purpose. This document provides guidance on the inspection, care and maintenance of scaffold boards to maximise their operational service life. This guidance is available for pdf download only.
The TG20 Design Guide provides technical data, commentary, and source material for use by competent and suitably qualified scaffold designers in circumstances which are outside the scope of standard solutions provided in the TG20 Operational Guide and TG20 e-Guide software. NASC members can purchase 10 or more copies of the TG20:21 Design Guide book at the discounted rate of £25 per unit. To do so, please email sales@nasc.org.uk
