<SG11> Robots may not intentionally grasp, grapple or attach to any Field Elements…

Okay, so obviously you need to grasp a Skyrise section in order to build your Skyrise, but once it is built, is it considered a Field Element? Or can your robot grasp and grapple and attach itself to the Skyrise tower once it is assembled?

Yes, this is legal.
