The engine links 4 of the inputs it tracks to construction: Steel, Aluminium, Copper & wiring, Timber & furniture.

The engine records which lines of business consume each input it tracks, by UK SIC code. These are the inputs it links to the SIC codes in this industry. It is an industry-level inference, not a claim about any one business.

Steel (SIC 41201, 41202, 42110, 42130)
Aluminium (SIC 41201, 41202)
Copper & wiring (SIC 43210)
Timber & furniture (SIC 41201, 41202, 43320)

Costs most businesses share

How this analysis was produced

Data sources: Office for National Statistics: UK Standard Industrial Classification of economic activities (UK SIC 2007); Atri engine: its input taxonomy, indexed analyses and the public track record
What the AI did: No AI wrote this page. It is assembled automatically from the engine: the inputs its taxonomy links to these SIC codes, the indexed analyses on them (each written by an AI model, with its own disclosure) and the graded track record.
Checked automatically: only indexed analyses are listed; no hit rate under 30 graded calls.
What people did: People mapped each input to the SIC codes of the industries that consume it. No person reviews this page before it changes.
