TG20:21 builds on TG20:13, the NASC’s innovative, user-friendly and widely-adopted eGuide software, which enables users to produce a wide range of standard scaffolding structures, without the need for bespoke design.

The latest version includes a number of revisions to make the process of producing compliant scaffolding – in accordance with the European standard BS EN 12811 – even simpler and a wider range of scaffolding types to make the software even more useful.

These additions include exterior birdcages, tube and fitting mobile towers, tube and fitting loading bays without beams and tied independent scaffolds with three inside boards.

TG20 compliance sheets will now be double-sided with an illustration and principal compliance criteria on the front side and detailed compliance criteria listed on the reverse in landscape format.

Users will be able to access TG20:21 – and the associated and updated Operational and Design guides – via a link from the NASC website using a unique serial number and login credentials rather than via a file download or CD.

The software will be available on an annual subscription basis, costing NASC members £75 per eGuide per year and non-members £300 per eGuide subscription per year. To ensure the transition for existing users from TG20:13 to TG20:21 is as fair as possible, there will be a short period of free use of the new software.

All TG20:13 users will have three months of TG20:21 free, while those that purchased TG20:13 in 2019 will receive nine months of the new software free. Those that purchased TG20:13 in 2020 and early 2021 will be entitled to use TG20:21 for free for 15 months before subscription fees apply.

NASC President Lynn Way said: “TG20:13 was a huge step forward for the scaffolding industry, revolutionising the way scaffolding contractors produce compliant layouts for day-to-day scaffolding and ensure their scaffolding projects are safe and conform to legal requirements. This tool has been widely adopted and appreciated by not only scaffolding contractors but also their clients, who have gained peace of mind that the scaffolding erected on their site is fully compliant and safe.

“TG20:21 is another step forward. The scope of TG20 been expanded and also further simplified – making it easier than ever to use and covering a broader range of scaffolding.

“On top of this, the TG20:21 suite will be accessible via a dedicated digital portal, again, making it much more user friendly. I’d like to thank all the NASC Committees that played a part in working on TG20:21 as well as our long-standing software developers CADS for their efforts in bringing it to life.

“Of course, the work doesn’t stop here and we’ll continue to innovate and improve in any way we can to make the scaffolding industry safer for all.”

TG20:21 will be supported by a comprehensive maintenance and development agreement, ensuring updates and improvements are made on a regular basis.
