The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Estimated: Wikipedia's[3] infobox and CTBUH give completion as September 2020 without a day, so the month's last day stands in. The tower had topped out earlier, in June 2020.
Opened primary project source for sourced buildout metrics and project timeline; researched 2026-10-29.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
