I'll be brief:
Housebuilders have scaffold up for a new build. Roof trusses arrive on site, waiting to be placed on the building. Truss racks are not constructed. They lean the roof trusses agains the scaffold. I disagree with the practice as its putting lateral stresses on the scaffold. Am I unduly concerned?

Unsure about the additional stress on the scaffold, however, would it not be safer to have these on the level to reduce the risk of them following?

Oops that should read falling not following.
Sorry

One or 2 against the scaffold is unlikely to make much difference, however a whole roof's worth of trusses would add significant lateral stresses to the scaffold.
As for laying them flat on the ground - do not do this, roof trusses must be stored vertically to avoid damaging them.
Ideally a specific scaffold frame should be erected to store them in the vertical and off the damp floor. the TRA provides guidance on the storage of roof trusses.

Hi A/B this is a frequent occurrence on sites with minimal space, generally the truss rack is erected next to/adjoining the scaffold scaffold may have additional bracing added if the trusses are particularly large/heavy.
In my experience this is an ideal position because the trusses can secured to the scaffold [blue rope usually] and can be lifted directly to the roof by crane when required, eliminating the need to move them around the site by forklift-as normally happens.

It's usually around 10 trusses against the scaffold.
I agree that one or two will not make much of a difference but 10 trusses on a scaffold that is loaded out for brickwork makes me nervous. My advice was to review the scaffold design and install additional bracing and ties as required.
Thanks for the replies.
