The line that scopes usually leave unstated
A scope saying that glass is included appears comprehensive and is not. Ground-level and internal glazing within safe reach is one proposition; anything requiring elevated work platforms, rope access or scaffolding is another entirely, with different equipment, different planning and a different order of cost. Leaving the boundary unstated means the routine work gradually covers less of the building than anybody realises. The gap is invisible from inside and obvious from the street.
Stating a reachable height fixes it. Everything below is routine and priced accordingly. Everything above is identified as periodic work with its own frequency and price, which the committee approves separately. Owners then know that the upper glazing is a planned item on a cycle rather than something that was supposed to be happening weekly and evidently was not. A planned item on a cycle is a very different thing from a service quietly not happening.
