Usage
Despite having narrow associations, "Dealer" may be a term used synonymously. "Constructor" appeared before in the piece "Construction" by Teodora Stepančić, a music game published in Synzine magazine #4 where apart from activities like "blindfolding" or "swapping instruments" Constructors were also tasked with manipulating cue-cards (which "theoretically" might intrude in Conductor's competences ;) ).
An overlap of roles is obviously not a problem in practice, but for designing the experience, it's worth keeping in mind that the relation between full-fledged Constructors and Players is not communicative in nature. When Constructors are given a lot of freedom the relation tends toward socially awkward and needs attention in testing especially for casual games. When Constructors are given specific tasks, this might soon get uninteresting for them and often this role should be best taken over by organizers of the meeting or other "crew".
Apart from obvious shuffling and dealing cards, in games with physical constraints like Houdini Exercise by Cornelius Cardew…
Improvise on your instruments with your hands tied behind your back.
… it would be Constructors' task to provide restraints. Players might also interact with this role similarly to Puppets like in a game from improvisational theatre: http://improvencyclopedia.org/games//Puppets.html
