NASC has updated its TG30 system scaffolding guidance to include a new range of birdcage configurations for cup, wedge and rosette systems.
The update expands the TG30 eGuide to cover 5 birdcage setups, including several configurations that NASC says were not previously available through TG30 or manufacturer user manuals.
Until now, contractors using these layouts would usually have needed a bespoke design.
NASC said the change is intended to reduce the time and cost involved in planning compliant birdcage scaffolds, while giving contractors a recognised route for standard solutions.
TG30 is NASC’s guidance suite for the safe design, supply and compliance of system scaffolding. It includes an Operational Guide, a Design Guide and an eGuide for generating compliance sheets.
All 3 are available through the NASC ePortal.
The new release covers freestanding birdcages, birdcages tied or butted in 1 direction, birdcages decked at the top 2 lifts, fully decked birdcages, and birdcages decked at the top lift with perimeter decking at all other lifts.
The configurations are available across cup, wedge and rosette systems.
NASC said the Operational Guide has also been updated to support the new configurations, giving users practical guidance alongside the new compliance sheets.
Mark Collinson, Head of Technical at NASC, said: “This update will make a genuine difference to scaffolding contractors working with system scaffolding.
“Many of these birdcage configurations were not previously covered anywhere, which meant bespoke design was the only option.
“Having them available as TG30 compliant solutions removes that burden, saves time and cost, and ensures contractors can proceed with confidence that they are working to the recognised industry standard.”
The full TG30 guidance suite and compliance sheets are available through the NASC ePortal.
