How is the field surface attached to the floor?

How is the FRP surface attached to the carpeted floor that is underneath?

Hi GDC!!
We were wondering, for design purposes, if you had any further details about how the FRP sheets are attached at regional events. I have heard that the official drawings are 3 long 50 foot sheets, but also that maybe they will be 4 x 8 sheets... Is there any definites at this point? (Basically, are the way in which they are attached going to cause a change in the friction in those areas, or is it negligible?)
Also, for the carpet border around the field, are the FRP sheets sunk into the carpet so that there is no edge from the sheets to the carpet, or is there a lip? (Although I think this will probably be less then 1/4" anyways, so mostly negligible)
We have talked to one of the field assembly people for the Seattle Regional, and he does not know yet how it will work, so we though we would ask.

Thank you!

How will the 3 long sheets of FRP be secured?

Will they be taped together with the gaffers tape mentioned in "2009 Arena Layout and Markings.pdf" ?

Will they be secured to the carpet in any way?

We are building a practice field and would like to emulate the actual field as much as possible.

For the competition fields, the Regolith will be made from three 8-foot by 50-foot rolls of the FRP surface material. The rolls will be taped in place to hold them in position on the underlying carpet. Edges of the FRP surface material will be taped down and the seams between the three pieces will be taped together with fiberglass tape with a friction characteristic similar to the FRP material. This will be done to prevent uneven edges/seams from "catching a wheel" during the game.
