Working platforms for tracked plant: good practice guide to the design, installation, maintenance and repair of ground-supported working platforms
On 1 June 2004, BRE published Working platforms for tracked plant: good practice guide to the design, installation, maintenance and repair of ground-supported working platforms (BR 470), written by Hilary Skinner.
Preparation of the guide was instigated by the Federation of Piling Specialists (FPS) as part of a drive to improve practices related to the use of piling and associated specialist plant. It was prepared by a BRE project team working under the direction of a steering group appointed by FPS.
Most ground-supported working platforms perform well; they are critical for plant stability, and safety is a vital issue. However, overturning of rigs has occurred more frequently than it should, and although incidents are relatively rare, fatalities have occurred.
The 52-page guide highlights important issues in the assessment, design, installation and maintenance of working platforms. Design calculations are given, together with worked examples for different subgrade properties.
However, it should be recognised that working platforms are subject to complex loading conditions and are difficult to design, requiring specialist advice. The guide is not intended to reduce the need for specialist designers, but rather to promote the implementation of minimum standards.
Its contents include:
- Site conditions.
- Operation, maintenance and repair.
- Appendix A: Design calculations.
- Appendix B: Determination of characteristic values of soil and geosynthetic parameters.
- Notation and abbreviations.
