Equipment availability decides the scope
The order most scopes are written in is backwards. Areas are listed, a price is agreed, and only afterwards does anyone establish that reaching a particular section needs a boom that will not fit through the roller door or a lift the site does not own. The area is then dropped quietly and the client continues to believe it is covered.
Reversing the order is straightforward. Walk the areas, establish the access method for each, then decide what is included. Some areas will be reachable from a fixed walkway or a platform the site already has. Others will need equipment, which is a cost and a logistics question that belongs in the quote rather than in a surprise conversation later. Recording the access method against each area, before pricing, is what prevents an item entering the schedule that can never be completed.
