Elevator, sprinkler and roof useful life in municipal policies
What 12 municipalities in Ontario and British Columbia state in 12 published asset management plans and capital asset policies, component by component, beside the library's sourced entry. Every life links to the page it comes from.
These are lives municipalities assume: amortization periods in capital asset policies (accounting lives) and replacement forecasts in asset management plans (planning lives). None is a measured age at replacement. Policies that copy one shared table count once.
