New TG20:21 guidance set to launch in the spring

NASC’s eagerly-anticipated eGuide scaffolding design software update and expansion of TG20:21 will go on sale from March, it has been confirmed.

The latest updated version of TG20 builds on TG20:13, the NASC’s innovative, user-friendly and widely-adopted eGuide software, with a number of revisions to make the process of producing a compliant scaffolding design even simpler and additions to make the software even more useful.

As demonstrated at the trade body’s AGM in November 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.

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

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

NASC members will benefit most with a set price of £75 per eGuide subscription per year while non-members will need to part with £300 for the same subscription per year. A full price guide can be found here.

However, the scaffolding trade body has said that existing users transitioning from TG20:13 to TG20:21 will have 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 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 day-to-day scaffolding designs and ensure their scaffolding projects are safe and compliant.

“TG20:21 is another step forward. Not only has the scope of TG20 been expanded but it’s also been further simplified – making it easier than ever to use and covering a broader range of scaffold designs.

“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.”
