Start with how the building will actually be used
A new premises has an intended use rather than an observed one, and the two rarely match exactly. Tell providers how many people will occupy it, when, which entries they will use, where they will eat, and which areas will see visitors. That information substitutes for history and lets a provider reason about wear and traffic rather than pricing from area alone, which is the fallback when nothing else is available.
Be honest about the uncertainty. If occupancy will build over six months, say so, and ask how the schedule would adjust. A provider who proposes starting lighter and reviewing at a set point is thinking about your actual situation. One who proposes a full schedule from day one may be right, but should be able to explain why the building needs it before it is fully occupied.
