Decide what the structure has to handle every week
Equipment storage, trailer cover, barn use, work space, and mixed acreage support all pull the project in different directions. That first use-case note is what usually makes the next step more useful.
Know whether you need open cover, enclosure, or both
A lot of property owners are still deciding between a pole barn, more enclosed shop space, or a mix of both. Mentioning that early helps frame the quote around real tradeoffs instead of guesswork.
Site-readiness matters, even if it is rough
You do not need the site fully finished, but it helps to mention whether access is clear, placement is chosen, and slab or pad work still needs to be discussed.
