Scaffolding in The Modern Day
This European Standard specifies performance requirements and methods of structural and general design for access and working scaffolds. Requirements given are for scaffold structures that rely on the adjacent structures for stability. In general these requirements also apply to other types of working scaffolds.
The purpose of a working scaffold is to provide a safe place of work with safe access suitable for the work being done. This document sets out performance requirements for working scaffolds. These are substantially independent of the materials of which the scaffold is made. The standard is intended to be used as the basis for enquiry and design.
Thus the requirements of BS EN 12811-1. TG20 is largely based on BS 5973 with extracts taken directly from the old code, it also uses permissible stress design method. However, TG20 received a mixed response from the UK industry and as a result TG20 is being re-written and the new version is due for release sometime in 2008. This is the reason for the 'limbo' situation. Until the release of the revised TG20 the HSE continue to allow scaffold to be built in accordance with BS 5973.

Famous quotes containing the words scaffolding, modern and/or day:
“The scaffolding must be removed once the house is built.”
—Friedrich Nietzsche (1844–1900)
“Tried by a New England eye, or the more practical wisdom of modern times, they are the oracles of a race already in its dotage; but held up to the sky, which is the only impartial and incorruptible ordeal, they are of a piece with its depth and serenity, and I am assured that they will have a place and significance as long as there is a sky to test them by.”
—Henry David Thoreau (1817–1862)
“The fox, he felt, had never seen his past disposed of like a fall of water. He had never measured off his day in moments: another—another—another. But now, thrown down so deeply in himself, into the darkness of the well, surprised by pain and hunger, might he not revert to an earlier condition, regain capacities which formerly were useless to him, pass from animal to Henry, become human in his prison, X his days, count, wait, listen for another—another—another—another?”
—William Gass (b. 1924)
