How we word it

  • The calculation follows BR 470 (BRE 2004) Appendix A for cohesive and granular subgrades.
  • Results are subject to project-specific ground investigation and verified plant loads.
  • The emailed Official Design Pack is the design record — on-screen output is a draft.

Why this tool

Plant failures and overturns are often platform failures. This designer implements the BR 470 (Working Platforms for Tracked Plant) Appendix A method for cohesive and granular subgrades, with optional geosynthetic reinforcement — the same engine behind our standalone bre470pilingmatdesign.com.

  • Free, unlimited design calculations — try rigs and materials until it works
  • 23 pre-loaded Liebherr, Bauer and Soilmec rigs (EN 996 parameters)
  • Instant cross-section and plan drawings, risk assessment preview
  • Pay only for the official deliverables — a traditional consultancy design costs £500–£1,000 and takes weeks

What the £299.99 pack contains

  • Working platform design certificate with unique reference
  • Full calculation audit trail to BR 470 (BRE 2004)
  • Drawings with title blocks — cross-section & plan
  • Site-specific working platform risk assessment
  • Notes, limitations and inspection requirements (WPC, BS 5975:2024, CDM 2015)

Important

The design is valid only for the plant, loading and ground conditions entered. Verify ground conditions on site, and have a Working Platform Certificate (FPS format) signed before plant is accepted onto the platform. Slopes steeper than 1 in 10, unusual loading or poor ground need a bespoke assessment.
