Continuous Accessible Path of TravelIn the past wall setouts on plans were based on stud frame to stud frame. With the implementation of AS1428.1-2009 Building Designers will need to carefully review setouts as the minimum spaces nominated must me unobstructed.

Typical obstructions include (but not limited to)

  • Skirtings & coved skirtings over 15mm radius
  • Architraves
  • Fire hose reels
  • Shelves,
  • Signage

This will mean where minimum widths are nominated ie a corridor of 1220mm may need stud offsets of 1276mmmm (1220mm + 20mm (2 x 10mm plasterboard), + 36mm (2 x 18mm skirtings).

Corridor widths, latch & hinge clearances, sanitary facilities etc will all be affected.
