There are many timelines on projects.
The most basic are:
Announcement
Ground Breaking
Topping out - completion of structural steel
Enclosure
Construction completion
Commissioning
Acceptance
Large facility construction is typically done from ground breaking to Construction completion in 19 months. After completion, there is a defined period of commissioning until the project is accepted with a warranty period thereafter.
I would argue that Announcement is not part of the construction time line, it is purely a Marketing decision and can be anywhere during the construction process.
