How sources are chosen and recorded: sourcing policy.
Municipal lives for conveying (D10)
9 municipalities in Ontario and British Columbia state a life for conveying as a whole, in 9 distinct tables: 20–35 years, median 20. These come from capital asset policies: accounting lives, used for amortization. They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. The dashed line is the median. Policies that copy the same table count once.

Open questions
- Only one source so far: HUD planning lives for US multifamily housing. Canadian and observed sources are needed.
- Elevator tasks come from NAVFAC MO-118 (1988), which restates the elevator code tests of its time; check them against the current ASME A17.1 and local requirements.
