Code of practice for temporary works procedures and the permissible stress design of falsework
Published By | Publication Date | Number of Pages |
BSI | 2011 | 228 |
This British Standard gives recommendations and guidance on the procedural controls to be applied to all aspects of temporary works in the construction industry. It also includes guidance on design, specification, construction, use and dismantling of falsework. This standard gives guidance on permissible stress design of falsework. This guidance is also applicable to the design of what is termed class A falsework1) in BS EN 12812:2004, the design of which is specifically excluded from BS EN 12812:2004.
Section 2 gives recommendations for the procedures required to ensure that temporary works are conceived, designed, specified, constructed, used and dismantled all in a safe and controlled manner.
Section 3 covers the design of temporary works and in particular the design of falsework and relevant formwork. In addition Section 3 covers: materials including material factors; loads and load factors; design of falsework, including both proprietary equipment and traditional scaffolding solutions; wind loading (reference to temporary and permanent stability) and reference to other British Standards for the design of structural steelwork, reinforced concrete and excavation support.
The structural design element in this standard is additional information necessary for the structural design of falsework. It can be used in conjunction with existing structural standards.
