I understand your Engineer point of view, but below those are the terms definied here in ssp: (Those definitions is what i follow
(regardless i am engineer and designer) independent what is done under ground of foundations and its huge costs, that we do not see growing up above street level)
On main page of this search form
http://skyscraperpage.com/diagrams/ passing the mouse above the status definitions you will see:
Built: Structure currently exists. Construction is complete and structure has potencial for use. Structures undergoing renovation remain on this category.
Construction: Structure is currently under-construction. Structural components are permanently assembled on-site. Excavation does not count as construction.
On-hold: [sub-item of construction] Construction had begun at one point but has now stopped. This is a sub category of construction.
Proposed: Structure is planned to be built and construction has not yet begun. Includes both structures which have been approved by local authorities and those which have not (we do not have distinct 'approved' category).
Stale-Proposal: The last news we have heard is that the structure was proposed but we have not heard any status updates for two years. After no news for five years a structure can be set as cancelled. This is a sub-category of Proposed which we use so that Proposals which drop from the news because they are most likely cancelled do not continue appearing in the standard diagrams.
Cancelled: Structure was at one proposed but has been cancelled by it's developer.
Destroyed: Structure at one time existed but no longer does. Includes structures which have been demolished, dismantled, imploded, destroyed in a terrorist act, destroyed by accident ,etc.
Vision: Structure's design is intended as an architectural vision only and is not to be built in it's current form. Vision structures do not get cancelled like proposed structures can.
Fantasy: Structure is a creation of our illustrators.
But i understand that the term 'Broken Ground' is controversal, cause what is done inside earth can not really be used for another goal of only a positive sky-direction useful building, cause we do not have a definition of 'negative' building going inside earth to the magma direction yet, as for 'building definition itself' all constructions normally goes higher from streets. This is common term of skyscraper we understand here. For more references see please
http://en.wikipedia.org/wiki/Skyscraper independent of huge foundation engineers point of view
(there is huge work underground for tunnels, stations, water drainage, bridges and whatever, that we don't include here, obvioussly) whether we here see only the 'Design' and 'Highest' or 'High' definitions aspect above the waterline (street) and visible to everyone.
I hope then closing this discussion, because this has nothing to do with the wonderful huge work for the 3D-Modeller here in this thread thema. It is ok in his model cause it was the tallest structure thought for the city already proposed there, that i hope one day to be really built. So it is a good reference to be kept. And sinceresly, this is REALLY OFF TOPIC.
