Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle building materials by type, performance, standards, environmental impact and hazards.

Any material used for construction, such as timber, stone, brick, concrete, steel, glass and insulation, including manufactured construction products.

What it is for: Constructing and maintaining buildings and infrastructure.

It can be select materials for a design; check performance declarations; estimate embodied carbon; reuse or recycle them.

Distinguishing features

Used in construction

Natural or manufactured

Performance declared under standards

Some legacy materials are hazardous

What it looks like

Blocks, boards, sheets, bars, aggregates and panels.

Physical character

concrete compressive strength: 20-50 MPa - common grades

timber density: 350-750 kg/m3 - softwoods to hardwoods

How it is recognised

CE or UKCA marking with declaration of performance

Product data sheets

Wooden buildings are made of materials but are not materials

Drafted structure

Bundle to layer to finding to question, as the second pass will find it: 4 bundles · 8 layers · 8 findings · 16 questions.

Type Which material.

Type decides use.

Kind

Masonry, timber, steel.

Kind

Material type.

  1. What material is it? definition
  2. Is it structural or non-structural? definition

Performance

Declared values.

Performance

Declared performance.

  1. What are its declared strength, fire and thermal values? measurement
  2. From which declaration of performance? provenance
Compliance Standards.

Compliance is required.

Marking

CE or UKCA.

Marking

Product marking.

  1. Is it marked under the applicable regulation? provenance
  2. Which harmonised standard? provenance

Fire

Reaction to fire.

Fire

Fire classification.

  1. What is its reaction to fire class? measurement
  2. Is it permitted in this use and height? boundary
Environment Carbon and reuse.

Materials carry impacts.

Embodied carbon

EPD.

Carbon

Embodied carbon.

  1. What is its embodied carbon per unit? measurement
  2. From which environmental product declaration? provenance

Reuse

End of life.

Reuse

Reuse and recycling.

  1. Can it be reused or recycled? action
  2. Is there a take-back scheme? action
Hazards Health and safety.

Some materials harm health.

Legacy

Asbestos and lead.

Legacy

Legacy hazards.

  1. Could the existing building contain asbestos or lead paint? boundary
  2. Who should survey it? action

Handling

Dust and weight.

Handling

Safe handling.

  1. What protection is needed when cutting or handling it? action
  2. Which safety data sheet applies? provenance

What the second pass must settle

  • Should each material be a separate entry?
  • How should declarations of performance be linked?
  • How should embodied carbon data be recorded?
