in London, ON·counted·1 all time
Construction activity at a school site, typically showing scaffolding, barriers, heavy equipment, or unfinished buildings.
Counted, not streamed: School Construction has no time series, so it is read as a footprint across places. All-time count by city.
Things that physically exist: street furniture, signs, buildings. All-time counts.
