TG20:13 Guide to Good Practice for Tube and Fitting Scaffolding was launched in February 2014, and replaced the previous guidance, TG20:08. TG20:13 was made up of four elements as detailed below.

The next version of TG20 is now launched. Further information about TG20:21 can be found here.

Use of TG20:21 was free of charge for three months from the date of launch (12th April 2021), for all users of TG20:13, and for longer for users who purchased in 2019, 2020 or 2021.

With the introduction of TG20:21, there was a ‘transition period’ to give the industry adequate time to adjust to the new requirements, in a planned and controlled way. Existing scaffolds constructed in compliance with TG20:13 and associated compliance sheets remained acceptable and did not require modification. TG20:13 compliance sheets were still valid and could continue to be used for the construction of new scaffolds for a few months.  TG20:13 was formally withdrawn, in favour of fully adopting TG20:21 on the 12th October 2021. Further information can be found here. 

Four elements of TG20:13

1. TG20:13 Operational Guide A full-colour, 224 page guide containing detailed practical guidance for most common types of scaffolding supported by structural research and calculations. Guidance was provided for an expanded range of structures which included independent scaffolding, interior birdcages, chimney stack scaffolds, loading bays, ladder-access towers, free-standing towers, lift shaft towers and putlog scaffolding.

2. TG20:13 Design Guide Intended predominantly for engineers and designers, this 206 page document provided technical data, commentary, and source material for use by competent and suitably qualified scaffold designers in circumstances which were outside the scope of standard solutions provided in the TG20:13 Operational Guide and TG20:13 e-Guide software.

3. TG20:13 e-Guide Designed for Mac, PC and tablet use, making it extremely easy to check scaffolds for TG20:13 compliance digitally, with user-friendly software which will facilitate printing and circulation of details of TG20:13 compliant structures by email.

4. TG20:13 User Guide A 32 page full colour pocket guide in A6 format, this document clearly summarised the requirements for compliant TG20:13 scaffolding and offered indispensable guidance to the scaffolding operative.
