replacement initiated
The identity of a structure on a site gives way to that of its replacement structure on the same site.
Replacement of a structure is initiated at the moment when the identity of one structure on the site is replaced with the identity of the next structure on the same site replacing it.
The event records the transition between the old structure and its successor on the site. It is distinct from merely announcing an intention to redevelop the property.
The replacement is another structure, rather than a tenant change or a change of use within the same structure. The site remains the common location of the successive structures.
