Introduction

TG20 is a guide to good practice for tube & fittings scaffolds produced by the NASC. The latest version of this guidance TG20:21 builds on the previous version TG20:13. There are a number of differences between TG20:13 & TG20:21. Perhaps the biggest change is in the way the new guide is delivered. Previously TG20:13 was outlined in two physical books, the TG20:13 Operational Guide & the TG20:13 Design Guide. These were accompanied by the TG20:13 e-guide software for producing the TG20 compliance sheets, but the software was only licensed for use on one machine. For TG20:21 the Operational Guide, Design Guide & e-Guide software have all been incorporated into a subscription based online portal called the NASC e-Portal. This allows for several devices including computers, tablets & smart phones to access the guide with one subscription.

There are a number of changes within the guide itself & the e-Guide software has also been updated to allow TG20 compliance sheets for a wider range scaffolds. Below is a list of some of the changes that have been made. Although this list is not exhaustive, we have tried to include the most important changes. A full list of the changes are listed within TG20:21 itself.
