Q. 18 Material of the external walls
42. The type of construction materials used for wall construction will be recorded on the based on the statements of the owners, of the administrators or of the building's tenants (or based on the personal examination of the enumerators).
Codes used:
Code 1 - Reinforced concrete, pre-cast concrete panels or steel skeleton framed concrete: for construction executed using sliding forms, as well as for buildings having prefabricated panels with reinforced concrete. Also, buildings constructed with steel skeleton frame (concrete pillars and beams), having exterior walls built from brick masonry, stone masonry, light-weight building slabs, or substitutes will be included in this category.
Codes 2 and 3 - Brick or stone masonry or substitutes: according to the type of materials used to execute the dividing panels between the floors (or between the ground level and the garret, in the case of one floor buildings): reinforced concrete (code 2), or wood (code 3). By "exterior walls executed using brick substitutes," walls made by using perforated bricks (with hollows), ceramic and concrete blocks, light-weight building slabs, etc.; therefore these buildings will also be coded 2 or 3, depending on the kind of material used to make the panel; curved red bricks and metal reinforcement panels have to be bonded to the reinforced concrete panels and will be coded 2.
Code 4 - Wood, logs, poles: when the exterior walls of the building are made from these materials.
Code 5 - Saplings plastered with wet clay, adobe or other materials: include those buildings using saplings plastered with wet clay, adobe, other materials (Wood Pressed Panels, rolled mud bricks, wattle, twigs, reeds, etc.).
For dwellings having the outer walls built using different materials (stone, wood, bricks, adobe, etc.), only the material having the largest proportion will be recorded. When the materials are used in equal proportion, the less resistant will be recorded.
