[RPG] Are there any rules for building demolition

The following two (rather official looking) articles from the old 3.5 archives at Wizards.com provide a quite in-depth look at (the rules for) aerial combat. If you haven't checked them yet, they seem to be an excellent starting point:

There are the grapple rules from Races of War:

Advanced combat is a somewhat disingenuous name, as it implies that these rules are more complex than the "basic" rules found in the PHB. In truth, some of them are and some are not. Mostly, we look at these rules as a revision of the existing rules to make them more useful to players and DMs. In part that means taking incomprehensible portions of the combat system (grapple, for example), and cutting them down into discrete actions people can actually use without a half-hour argument. Partly this means taking basic combat actions and making sure that they have a valid purpose at all levels of play.

...

Grapple is collectively 3 separate maneuvers that all fall under the super-heading of "grappling". Any grapple attempt provokes an attack of opportunity unless your attack has the edge.

These three manoeuvres are: grab on, Hold down, and lift. When combined with the Tome of Battle manoeuvres that provide for some fairly judo/akido like moves, you should have a fairly straightforward martial arts system. You may also want to look at the Tome of Tactics (homebrew) or the Cthonic Serpent homebrew school or 8 more lesser disciplines. They all offer "grapple" mechanics or powers that should, if synergized, offer an appropriate milieu for your wrestler.
