The Federation of Piling Specialists (FPS) has published the latest edition of its Working Platform Certificate (WPC/4e), reinforcing a safety initiative that has played an important role in reducing tracked plant incidents for more than two decades.
Developed originally in partnership with the Health & Safety Executive (HSE), the Working Platform Certificate requires the Principal Contractor to confirm that platforms are properly designed, constructed, and maintained for the equipment operating on them. This simple but powerful intervention has transformed industry practice and is widely acknowledged as one of the FPS’s most important contributions to site safety. Since its introduction, the WPC has been credited with significantly reducing rig overturning accidents and has been recognised internationally as best practice.
The newly released guidance (July 2025) builds on this foundation by bringing additional clarity and detail to the requirements for design, verification, and ongoing maintenance. It introduces more comprehensive design data, including information on plant configuration, platform material, drainage provision, and geotextile reinforcement. It also places greater emphasis on sustainability by encouraging designs that are safe, efficient, and conscious of both cost and carbon. A revised inspection log has been incorporated, requiring weekly checks and recording of any repairs or reinstatement after events such as heavy rainfall, excavation or flooding, ensuring that platforms remain compliant throughout their working life.
Commenting on the update, Andy Heathcote, Technical Director at Keller and lead on the revision, said: “Working platforms remain the first line of defence against rig instability. This update ensures the Certificate not only reflects current best practice but also addresses emerging issues such as the performance of recycled aggregates, drainage and sustainability in design. It remains a vital tool in raising and maintaining safety standards across our sector.”
Malcolm O’Sullivan, FPS Chair said: “The FPS pioneered the Working Platform Certificate to embed accountability and competence in platform design and management. The updated guidance reinforces those principles, ensuring that safety remains at the heart of piling and geotechnical operations.”
The Working Platform Certificate (WPC/4e) and accompanying guidance are available now from the FPS website: https://www.fps.org.uk/guidance/working-platform-guidance/#accordion1
