Intended predominantly for engineers and designers, this A4 sized 206-page document 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 TG20:13 Operational Guide and TG20:13 e-Guide software.

This guidance note is concerned with advice for the safe erection, use and dismantling of temporary suspended chutes intended for the conveyance of waste construction materials. The guidance covers chutes constructed of detachable sections made of metal or non-metallic material, attached to scaffolding.
BS2482:2009 defines both visual and machine strength grading standards for 38mm x 225mm boards supported at 1.2m spans and 63mm x 225mm boards supported at 2.5m spans; and machine strength grading standards only for 38mm x 225mm boards supported at 1.5m spans. This guidance is reviewed on the basis of removing A grade boards that should not exist. A visually graded board is still a BS2482 product and should be marked as such on the end band.
An A4 full-colour, brand new, 224-page guide containing detailed practical guidance for most common types of scaffolding supported by structural research and calculation. Guidance is provided for an expanded range of standard structures which includes independent scaffolding, interior birdcages, chimney stack scaffolds, loading bays, ladder-access towers, free-standing towers, lift shaft towers and putlog scaffolding. A range of TG20 ‘compliance sheets’ is included for these structures. (Price shown includes £6 Postage & Packaging)
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.
