The reader is a group, not a person
A facility manager reading a quote brings context, compares it to what they know and asks a specific question. A committee brings none of that. Its members have different levels of interest, no shared reference point and no reason to have read the document closely before arriving. Anything requiring interpretation will not be interpreted; it will be deferred to the next meeting for clarification. Nothing about that is a criticism of committees; it is simply how group decisions work.
That changes what a good proposal looks like. Length works against it, technical detail works against it, and anything that requires the reader to hold several pages in their head at once works against it. What works is a short document where each area has a frequency and a price beside it, and where the decision being asked for is stated plainly at the front.
