At In House Design, we have a vast experience of scaffold design and detailing. We have worked on a large range of projects including small domestic dwellings through to multi-million pound scaffolds. We undertake commissions for the design of access, lifting, temporary support and shoring.

Our scaffold design services include;
  • Initial advice and feasibility studies
  • Tender designs
  • Scaffold design drawings
  • Scaffold design calculations
  • Design risk assessments
  • Independent design checking of 3rd party schemes
  • Independent site inspection of installed scaffold structures and reports
  • As-built surveys and record making
  • Structural frame analysis
  • Scaffold collapse investigation & Expert Witness
  • Temporary props and shores

When is a scaffold design required?

The Health & Safety Executive Scaffold checklist states - “Unless a scaffold is a basic configuration described in recognised guidance e.g. NASC Technical Guidance TG20 for tube and fitting scaffolds or manufacturers' guidance for system scaffolds, the scaffold should be designed by calculation, by a competent person, to ensure it will have adequate strength and stability”

The checklist also lists the Scaffold structures that need to be designed;

  1. Dead Shores
  2. Flying shores
  3. Raking shores
  4. Cantilevered scaffolds
  5. Truss-out Scaffolds
  6. Access Birdcages
  7. Façade retention
  8. Access scaffolds with more than the 2 working lifts allowed with TG20 'Basic Scaffolds'
  9. Buttressed free-standing scaffolds
  10. Temporary roofs and temporary buildings
  11. Support scaffolds
  12. Loading Bays founded on the ground
  13. Mobile and static towers outside base/height limitations
  14. Free standing scaffolds outside base/height Limitations
  15. Temporary ramps and elevated roadways
  16. Staircases and fire escapes

  20. Offshore scaffolds outside Offshore Contractors Association (OCA) handbook
  21. Pedestrian footbridges or walkways
  22. Slung and Suspended scaffolds
  23. Protection fans, Nets and Pavement Frames
