Access is the binding constraint
A workshop timetabled across most of the day and locked outside it has a very narrow real window. Assuming after-hours access without confirming who unlocks the building, whether an alarm is involved and whether that person is available on the scheduled evening is the most common reason a workshop scope is never delivered as written.
Establishing it takes one conversation with the business manager or facilities contact. The output is simple: who opens the space, on which evenings, what the alarm arrangement is, and who to call when it fails. Recording that in mobilisation is what turns a workshop from an aspirational line in a scope into an area that is actually serviced. Recording the arrangement in the proposal, with the contact named, is what allows a relief attendant to proceed without a series of phone calls.
