NASC TG20:13 Good Practice Guidance for Tube and Fitting Scaffolding Price Revision

Following a consultation exercise in the of summer 2016 an NASC working group was formed to review feedback and agree modifications and amendments to TG20:13 at time of next revision.

A consultation document was circulated to all NASC member companies and also to purchasers of TG20:13. Users and purchasers were invited to propose amendments to TG20:13 which they would like to see incorporated at time of next revision.

Suggested amendments included varying the number of boarded lifts, production of basic drawings and calculations, and increased leg load information.

It was also suggested that modifications might be made to the TG20 compliance sheet, for example incorporation of postcode, unique scaffold number and seasonal information.

The principal purpose of the consultation exercise was to enhance TG20 guidance with a view to improving safety and efficiency.

Unsurprisingly the exercise generated a considerable number of responses, many of which were quite detailed.

Working group meetings took place in September and November of 2016 to consider the merits of suggestions received, based on consolidated feedback prepared by the technical authors of TG20:13, CADS (Computer and Design Services Ltd).

A third working group meeting is scheduled in March 2017.

In the first instance the aim of the working group was to classify suggested amendments and modifications to TG20 on the basis of (1) desirability and (2) ease of implementation.

It was agreed that ‘quick wins’ should be incorporated to a software upgrade for issue free of charge to existing users of TG20:13.

It is envisaged that the software upgrade will be issued in the spring of 2017.

More substantive changes will then be agreed for incorporation to an updated version of TG20:13 at time of full review.

The timescale for full review has not been agreed. However it is unlikely that a fully updated version of TG20 will be published for at least two years.

Further to the above, and as TG20:13 has been widely adopted throughout the UK scaffolding industry and the wider construction sector both in the UK, and increasingly abroad, it has been agreed that now would be an appropriate time for NASC to announce a review of the existing TG20:13 publications pricing structure.

Accordingly it has been announced by the NASC that with effect from 1 March 2017 all TG20:13 publications will be half price, with the exception of the TG20:13 pocket user guide.

This price reduction will apply to NASC members and also to non members.

TG20:13 was originally launched in April 2014.
