What it is Filled

A vertical building element that encloses or divides space, and may carry loads, resist weather, separate fire compartments and reduce sound.

Why it exists Filled

Let an agent describe walls by role (load-bearing or not), construction, performance and position, which decide what may be changed and what rules apply.

Distinguishing features Filled

  • Vertical, unlike floors and roofs
  • Load-bearing and non-load-bearing walls have different rules
  • External walls must resist weather and heat loss
  • Party walls carry legal rights and duties

What robots and AI may and may not do Filled

Must not

  • Remove or cut a wall that may be load-bearing without an engineer's assessment.
  • Breach a fire-separating wall without restoring its rating.
  • Fit combustible cladding or insulation where the rules forbid it.

Only with a human decision

  • Any structural alteration of a wall.
  • Building or demolishing a boundary wall shared with neighbours.

May

  • Report cracks, damp and damage on walls it is authorized to inspect.
  • Record a wall's construction and fire rating from building documents.

Moral aspects Filled

  • Walls protect people from fire and weather; cutting corners has cost many lives.
  • Shared walls involve neighbours' rights.

Who is affected

  • Occupants
  • Neighbours
  • Firefighters

Owners Filled

Steward

The owner of the building; the building control authority approves structural work.

related

  • building - building element
  • room - rooms are enclosed by walls
  • building code - structure, fire, energy
  • free-standing wall or fortification - boundary and defensive walls are related

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.wall-q2547819
  • Wikidata: Q2547819 (https://www.wikidata.org/wiki/Q2547819)

Direct properties not applicable Not applicable

  • thickness: 75-600 mm - stud partitions thin, solid masonry thick
  • thermal transmittance: 0.15-2.0 W/m2K - new external walls low
  • sound reduction: 30-60 dB

Plane INF: no invented physical properties.

Recognition optional Filled

  • Vertical plane dividing or enclosing space
  • Thickness and material hint at whether it is load-bearing, but only a survey confirms
  • Party walls separate neighbouring properties
  • A vertical surface of plaster, brick, stone, timber or cladding, with openings for doors and windows.

Capabilities and actions required Filled

  • build it, from masonry, concrete, timber or steel studs
  • alter or remove it, which may need structural and legal approval
  • fix things to it, depending on its construction
  • insulate or repair it

Hazards and failure modes required Filled

  • Removing a load-bearing wall without support
  • Damp and condensation
  • Cracking from movement
  • Combustible cladding on external walls

Standards and interfaces required Filled

  • Building codes on structure, fire and energy performance
  • Party wall legislation, such as the Party Wall etc. Act 1996 in England and Wales
  • Eurocode 6 masonry design

Context of use required Filled

  • Enclosing buildings, dividing rooms, carrying loads and separating properties.
  • load-bearing and non-load-bearing
  • external, internal, party, retaining
  • by construction: masonry, concrete, timber frame, metal stud, infill
  • religious and cultural walls such as a qibla wall

Sources Filled

  1. Wikidata item Q2547819: wall - identity and sense of the item
  2. Wikipedia (de): Wand (Bauteil) - general description of the item

Open questions

  • Should wall types be separate entries?
  • How should load-bearing status be recorded and verified?
  • Is the Wikidata plane for this entry correct, given it sits under media?
