Accident cost as a share of contract sum (Singapore building contractors)

What it is. 0.25% of contract sum, insured (0.15%) plus uninsured (0.1%) accident cost.

Sample. A questionnaire survey of Singapore building contractors, 2011. Read from the paper's own abstract; the sample size is not stated there.

What it is not. Singapore building work, not Australian civil, and contractors' own survey estimates rather than cost records. The full paper has not been read, so the sample size is unconfirmed. A weak Indian study found about 0.48% accident loss; the often-quoted '7.9% to 15%' comes from 1990s US data that could not be verified and is excluded.

History

• 2026-09-25 Previously read only as a search snippet (secondary, unverified). Now read from the paper's own abstract, which confirms the 0.25% and adds the insured and uninsured split. A survey of contractors' own estimates grades moderate under METHOD.md Section 4. The title and industry (building, F41) are corrected from the abstract.
