BS 5975 Temporary Works Changes - Overview

This guidance is to give a brief overview of BS 5975:2019 and the main differences from the previous revision, which came into effect on 31st May 2020.

British Standards

British Standards (BS) is a code of practice and takes the form of guidance and recommendations.

Do organisations have to "legally" comply with British Standards?

HSE states: - Normally the use of standards is voluntary and they do not impose legal responsibilities. However, in some cases legislation may "call-up" a specific standard effectively giving it legal force...

Compliance with a British Standard does not confer immunity from legal obligations.

Main Changes

  • Detailed procedures included for all organisations including Clients
  • Responsibilities and duties listed for duty holders
  • Updated Terms and Conditions
  • Takes CDM 2015 into account
  • Clarifies responsibilities where Client appoints a sub-contractor
  • Traceability of responsibility to Directors
  • Allows multiple Temporary Works Co-ordinator's (TWC) to be used on site
  • Added an execution risk process
  • Listed the requirements for the Temporary Works (TW) register
  • Requires an effective system for checking both design and implementation
  • Requires organisations to check the competence of the organisations they employ to carry out the temporary works
  • Principle Designers to have a TW procedure
  • Requires TW Implementation Plan to include an inspection and test plan

General Information
The description of Temporary Works remains as:
Engineered solution to support or protect existing structure or permanent works during construction, or support item of plant or equipment, or the vertical sides or slopes of an excavation during construction or to provide access.

But now specific examples are identified:

  • Hoardings, haul roads, fencing and stairs
  • Supporting/restraining plant, materials or equipment
  • Supports and slopes to excavations and diversions to water courses
  • Safe working platforms
  • Measures to control noise, dust, debris, fume air quality, ground water, site discharges
  • Protection or support to services
  • Facilitating testing (e.g. pressure testing pipes, pile testing)

All organisations involved in a project which is likely to have Temporary Works are to have a procedure outlining how duties are discharged (not just the organisation carrying out the Temporary Works but the organisations employing them as well)

A design brief should be prepared, except for very low risk Temporary Works, by the site team and issued by the Temporary Works Co-ordinator to the temporary Works Designer and if the design check category has not been specified the Temporary Works Co-ordinator and Temporary Works Designer can confirm the category.
