Why should you use BS 5975 - Temporary works procedures?
BS 5975 on temporary works procedures gives recommendations and guidance on the procedural controls to be applied to all aspects of temporary works. It also includes guidance on design, specification, construction, use, and dismantling of falsework and guidance on permissible stress design of falsework. This guidance also applies to the design of what is termed “class A” falsework in BS EN 12812, the design of which is specifically excluded from BS EN 12812.
Section 1 of BS 5975 gives recommendations in relation to training and education.
Section 2 gives recommendations for the procedures required to ensure that temporary works are conceived, designed, specified, constructed, used, and dismantled in a safe and controlled manner suitable for all construction projects.
BS 5975 recognizes that more complex projects require more control measures and that additional client-specific procedures might be required on major infrastructure projects. Section 2 includes clauses on the roles of clients, permanent works designers, and construction management organizations.
Section 3 covers the design of temporary works and in particular the design of falsework and relevant formwork. It also covers:
- Materials including material factors
- Loads and load factors
- Design of falsework, including both proprietary equipment and traditional scaffolding solutions
- Wind loading (a 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.
What’s changed since the last update?
This edition revises Sections 1 and 2 of the 2011 version. The principal changes are:
Details about the procedures which clients, permanent works designers, and temporary works designers should adopt have been added.
BS 5975:2019 on temporary works procedures has been updated to take account of the Construction (Design and Management) Regulations 2015 (CDM), particularly in respect of the interface between the design of permanent works and the design of temporary works.
Terms and definitions have been updated.
The principal contractor’s temporary works coordinator (PC's TWC) retains overall responsibility for the temporary works on the site, but where another contractor manages their own temporary works within that site, they have their own procedures and appoint their own TWC.
