BS 5975: 2018 Draft for Public Consultation (September 2017)
Consultation document issued, 1.9.17
The British Standards Institution (BSI) has published a draft for public consultation (DPC) of BS 5795:2018, Code of practice for temporary works procedures and the permissible stress design of falsework. When finalised, and published subsequently, it will supersede BS 5975:2008+A1:2011.
The DPC is a revision of Sections 1 and 2 only of the existing standard. Section 3, on the permissible stress design of falsework, remains unchanged.
The following principal changes have been introduced:
1. There is more detail about the procedures that clients, permanent works designers and temporary works designers should adopt.
BS 5975 was always intended to be used by all organizations “involved in temporary works” and provided details of the procedure contractors should adopt, but lacked detail about the procedures that clients, permanent works designers and temporary works designers should adopt.
2. The terms and definitions have been updated to align with the CDM Regulations 2015 (CDM2015). Compliance with the CDM2015 has been incorporated, particularly in respect to the interface between the design of permanent works and the design of temporary works.
3. The role of assistant temporary works coordinator (TWC) has been introduced.
The Principal Contractor’s TWC retains overall responsibility for the temporary works on the site. The drafting committee understood that some organizations are using the temporary work supervisor (TWS) of sub-contractors to act as de-facto TWCs, but this is not now recommended. Only if the PC’s designated individual (DI) deems the contractor’s or sub-contractor’s procedures acceptable is the contractor or sub-contractor permitted to plan and manage its own temporary works and appoint an assistant TWC to do so.
4. Section 2 includes recommendations for designers on the likely partial safety factors to be used in limit state design of temporary works and on design considerations to be applied for all temporary works design.
