First provides information to build some build elements to regions prior to kick off. The information is tightly controlled and only enough to to build the selected elements. They do not release the entire field drawings prior to kick off. At least not for the last few years.

Disclaimer: My team has hosts a practice field. The people who build the region's field elements are not on my team & do not share any information with us prior to kick off. As it should be.
