What to put in the pack
Start with an area list that a stranger could follow: level, room or zone name, approximate size or seat count, and floor finish. Add the task schedule underneath, with a frequency against each task rather than against the visit. Then set out the conditions that shape the work, including trading hours, service window, access method, waste route and any induction the site requires. Finally, state the format the response must take. Four pages is usually enough, and it saves far more time than it costs.
Resist the urge to describe your ideal outcome instead of the work. Aspirational language reads well and prices badly, because every bidder converts it into a different number of hours. Concrete lines produce concrete responses. If you genuinely do not know how often something should be done, say so and ask each provider to recommend a frequency with their reasoning, which turns an unknown into a comparison point rather than a hidden assumption buried inside the total.
