An unmentioned area is assumed to be covered
Committees reading a cleaning scope naturally assume that anything not excluded is included. That assumption is harmless for a corridor and consequential for a switch room. Where a scope says nothing at all, an owner walking past an untidy plant room concludes the contractor is not doing the job, when in fact the area was never within anyone's arrangement. The contractor then has no way of correcting an impression they never created.
Writing exclusions explicitly costs nothing and prevents that entirely. It also does something more useful: it prompts the committee to ask who does look after those areas, which in a surprising number of schemes turns out to be nobody. The exclusion list therefore serves as a small audit of the parts of common property that fall outside every arrangement the scheme holds. That is a useful thing for a committee to discover in a proposal rather than in an incident.
