Hi. I personally would use building=construction only for the building that get's constructed currently, as it's the building key. Even a small area around that belongs to the construction site is landuse=construction, but building=construction (as it's no building).
But if I knew the buildings outline, I would tag it as building=construction as it's easy to change the value later. regards Peter Am 06.07.2013 03:26, schrieb L.
