It is often difficult to get faculty interested enough in a project to sit down with you to write a grant proposal, but they will turn out en masse and full of intense passion to defeat a proposal put forth by administration. Issues such as release time, new offices, larger class size, quality of students, etc., become stumbling blocks and tend to polarize faculty and administration. A grant writer must understand that these issues exist and find a way around them without making enemies of one side or the other. A friendly relationship with the faculty union rep and with each department and curriculum chair can go a long way toward alleviating potential troubling situations. A little subtle bribery can also alleviate potential stumbling blocks.
Many college administrators are lazy.
There is a school of thought among administrators that posits the view that the problem will go away or someone else will handle it if you don't do anything. Try to get an administrator to fill out a form, read an important document, meet a deadline, get a price on an item, give you some data they already have on hand, etc. I told you I needed it two weeks ago. I'll get to it right away. Some administrators hate each other.
