Practical Hoarding Doorways

Door opening requirements, offset uprights & head height calculations

Doorway Requirements

Installing a doorway in a Practical Hoarding requires a Doorway Frame to be constructed within the on-site-built frame. The doorway frame provides structural support above and around the door opening.

Offset Upright Requirement

All doorways in NXGN hoardings use inward-hinged doors — they open into the works area, away from the public. This requires Offset Uprights at the doorway to ensure:

  • The door can open fully inward without hitting weight blocks
  • Weight blocks are positioned behind the hoarding line, clear of the swing arc
  • The doorway remains unobstructed for safe passage

Door Head Height Calculation

The door head height for Practical Hoardings is calculated using the same formula as Panel Hoardings:

Formula: Door Head Height (DHH) = Panel Height − Door Opening Height

For example, with a 2400mm tall hoarding and a 2040mm door opening, the door head height is 360mm.

Construction Sequence

  1. Mark the doorway position on the top and bottom plates
  2. Install opening studs (DOST) at each side of the doorway
  3. Construct the doorway frame above the opening
  4. Fix skin around the doorway — see Skin Fixing Specification
  5. Install offset uprights at the doorway
  6. Hang the door — see Hanging Doors
