BS 8560:2012 pdf download.Code of practice for the design of buildings incorporating safe work at height.
3.6 Production information: pre-construction stage
The fundamental principles of the aesthetic, structural and dimensional design of the building should have been agreed by this stage and only minor changes should be undertaken- At this stage the following should be prepared and finalized for tender a) detailed information for the construction phase;
b) risk management documentation (pre.construction information);
C) information for options on temporary fall protection systems (e.g. Figure 2, Key 13 and 14) where unusual and significant work at height is required.
NOTE 1 Where the shape/form of the building design demands unusual or specific requirements of the temporary works and access systems, the design team might need to have a greater input into its design.
NOTE 2 The main contractor and specialist subcontractors are usually responsible for designing temporary works, including access and fall protection for the safety of those working on the temporary works.
The information provided by specialists should be analysed and integrated into the design.
NOTE 3 If detailed specialist contractor information is not available at this stage, this can result in late changes after contract appointments are signed causing disruption to the procurement process.
3.7 Tender
3.7.1 Tender documentation
At this stage tender documentation should be prepared in sufficient detail to enable tenders to be obtained for the project. Preconstruction information should be included to enable tenderers to make allowance for temporary works, protection and safety measures.
Where there are unusual work at height hazards that present significant risks, relevant information should be provided and highlighted in the tender documents and drawings
NOTE 1 Significant risks are not necessarily those that involve the greatest risks but those including health and safety risks that are:
a) nor likely to be obvious to a competent contractor or other designers,
b) unusual;
c) likely to be difficult to manage.
A list of itemized health and safety critical items should be included in the invitation to tender documents. The itemized costs in the tender return should be used for assessment.
NOTE 2 It is recognized that including too much generic information in the tender documents is unhelpful.
3.7.2 Tender appraisal
Potential contractors andlor specialists should be identified and evaluated. Returned tenders should be appraised and then recommendations should be made to the client by the design team on their suitability. Returned tender documents should be specifically analysed to identify how contractors address work at height issues. In the case of design and build this should include the appraisal of the design and build contractors proposals regarding any operational work at height requirements. Specific questions relating to work at height should be asked at contractor interviews, Alternative proposals for work at height submitted by contractors should be evaluated.
Any value engineering process should refer back to the recorded design decision and rationale to ensure that the work at height objectives have not been compromised.
3.8 Construction phase
The contractor should utilize the information provided by the design team about significant risks arising from the design to manage those risks during the construction phase.
Where significant design changes are proposed during the construction phase. these changes should be reviewed to take into account the impact on safe work at height. Where the contractor is responsible for completing the design, the contractor and specialists should provide detailed fabrication drawings or alternative designs as early as possible after being awarded the work. The design team should review and assess these against the detailed design to ensure that the objectives of the design, including sate work at height, are met.
On practical completion, information relevant to safe work at height practices for cLeaning and maintaining the building should be given to the owner/occupierluser of the building by the design team; this might include information providedldeveloped by specialist suppliers of equipment.
NOTE Typically this information is included in the health and safety file.
4 Communication
Designers should communicate their intentions with regard to the management of safety risks (as with other aspects of the design) to the rest of the design and construction team, using building information modelling (BIM) systems, drawings, sketches, written schedules and specifications in an agreed format.
Information should be provided in a format that is clear to the user and focuses on the significant health and safety risks present. This should be achieved by means of symbols and written annotations on project drawings (see Figure 7).
Generic, trade competency or trade interlace related and obvious health and safety risks should not be highlighted in this way unless the context makes them unusual. Residual significant risks should be highlighted on drawings to enable the contractor to plan for and manage these risks Where there is complexity, a more detailed register for coordinating health and safety risks, referenced to the drawings, should be used.
