The common areas take the load
Every item entering the building passes through the entry, the lift and one corridor, on trolleys, repeatedly, over one or two days. That produces scuffed lift car walls, marked door frames at every turn, floor soil tracked from a street or a loading area, and packaging debris along the whole route. None of it happens inside the new tenancy, which is where people assume the mess will be. The mess is on the route rather than in the tenancy, which is where people expect it.
So the effort moves to that route for the duration and detail work elsewhere waits a cycle. That is a decision made with the building contact rather than unilaterally, because other tenants notice a reduction and will attribute it to declining service unless somebody tells them there is a move-in and the common areas are being prioritised. Other tenants will attribute a reduction to declining service unless somebody tells them otherwise.
