The Federation of Piling Specialists (FPS) Technical Committee convened on 12th February 2025. Chaired by Jon Ball (RBL), the meeting covered a range of technical discussions, ongoing task groups, and industry updates, with participation from key representatives across the sector.
Key Updates and Actions:
- – Concrete Blowing Out Task Group – The task group focused on clearing concrete lines continues its work, with the latest quarterly meeting highlighting the absence of consensus on a universal solution. Ongoing research at Swansea University aims to determine whether aggregate interlock is the primary cause of blockages. Initial findings are expected within the next six months, offering further clarity on the issue.
- – Rigid Inclusions and B526 Code Developments – Feedback from FPS members has been incorporated into discussions at the B526 code meeting. The preferred approach remains under debate, with a key divergence on whether a material factor or resistance factor method should be adopted. While progress has been positive, FPS continues to monitor developments to safeguard industry interests.
- – CIRIA Chalk Code Working Group – Zoe Baldwin is leading FPS’s engagement with CIRIA on its piling guidance. The FPS has sponsored CIRIA’s work and additional volunteers are being sought to contribute, particularly those with expertise in pile design for chalk.
- – Tip Testing and Integrity Testing Guidance – Discussions on tip testing and data interpretation continue, with further trials needed to refine findings. A consolidated review of existing trials is planned to identify best practices and avoid duplication. Additionally, Chris Barker updated the committee on the EFFC-DFI Non-Destructive Testing guidance document. The FPS will play a role in developing evaluation criteria, ensuring alignment with European standards.
- – Continuing Professional Development (CPD) Initiatives – The FPS is considering reintroducing CPD sessions within Technical Committee meetings. Chris Barker proposed Tremie concrete as the first subject to be discussed, which was well received. Plans are also in place to make CPD sessions accessible via Teams to a wider audience, including the FPS Early Careers Group.
- – Debonding Foam and Best Practice Guidance – Concerns were raised regarding inconsistencies in site practices, particularly around lifting bands and debonding. FPS guidance is acknowledged as a solid foundation, but further clarity is needed. A proposal was made to create a focused guide to improve understanding among groundworkers and standardise best practices.
- – Innovate UK’s Green Concrete Initiative – The FPS is exploring participation in an initiative led by Innovate UK to encourage the adoption of low-carbon concrete. The programme aims to provide manufacturers with clear market demand signals to support production at scale. While the cost of green concrete remains a challenge, FPS members are being asked to quantify anticipated demand to assist with market development.
- – Eurocode 7 Revisions – Jon Ball provided an update on Eurocode 7 revisions, which introduce simplifications in design methodology. The revised code will transition from DA1C1 and DA1C2 approaches, adopting a single equivalent method. The FPS is monitoring the implementation timeline to ensure smooth adoption and clarity for members.
- – Working Group Progress – Cage Workability and Safe Lifting. Paul Wiltcher reported steady progress. Collaboration with associate members has been productive, and work is nearing completion. The group is expected to disband upon finalising the handbook.
- – Sustainability by Design – Dimitrios Selemetas presented a draft document outlining the FPS’s approach to sustainable design. Further refinement is planned.
- – Digital Data Sharing – Scott White reported that funding has been secured to trial a new digital mapping system for piling data. The initiative aims to improve data accessibility and support pile reuse. A spreadsheet-based data entry tool is currently in development, with the FPS positioned as the data custodian.
- – Micropile Execution Codes – While currently on hold, the FPS continues to monitor the development of micropile execution codes. Future action is expected once national annexes are finalised, with potential code mergers under discussion.
- – Working Platforms Task Group – Under new leadership, the Working Platforms TG is focusing on revising safety guidance and inspection protocols. The group will review FPS’s working platform certificate to align with EFFC guidance. A key priority is updating outdated research and ensuring clarity on best practice standards.
- – FPS Audit and Compliance – The FPS audit programme is progressing well, with a rapid completion rate. Key areas of focus include site safety compliance, lead engineer competency assessment, and mandatory carbon reporting. FPS is also aligning with Build UK’s Common Assessment Standard (CAS) to strengthen recognition of FPS-accredited contractors.
