Two populations, one lobby
Commercial occupiers judge an entry between about seven and six on weekdays. Residents judge it at every hour including weekends, and they carry a different set of concerns: parcels, prams, luggage, shopping and pets all pass through the same space. An office-hours cleaning pattern leaves the lobby at its worst precisely when the residential population is most present, which is Friday evening and Saturday. The two populations rarely conflict; they simply need the area to present well across a longer span than either alone would require.
The schedule therefore has to span more than a business week. That does not necessarily mean more attendance, but it does mean the attendance is placed differently: a weekend presentation visit, an evening check, and a lighter mid-week pattern often serves both populations better than five identical weekday services. Setting it out this way in the scope lets bidders price the actual requirement. Setting it out this way also lets the committee and the commercial tenants see what each part of the schedule is for.
