That describes a project receiving pyramid facing stones quarried from white Tufa limestone.

But I doubt there is any indication whether this was for maintenance work, or original construction.

Pharaohs were always embarking on patch-up and upgrade projects on ancient stuff, and tagging everything they touched with their personal cartouches (often having their predecessors' chiseled out, first). So it is very hard to know who really built what, or when. The Sphinx is officially ascribed to a Pharaoh who leaned a stela on it bragging about maintenance work he had ordered (a thing there are also a lot of).

But they never tagged pyramids.
