Metal Deck on wood floor joists

[dcceecy]

It's a renovation of a bathroom.

The design will be light-weight concrete (reinforced with WWF) on metal deck (9/16", 22 GA) supported by wood floor joists (2x @ 16" OC).

Usually the metal deck is attached to steel joists, but here the deck is fastened to wood joists. any suggestiions on how to fasten the metal deck to wood joists?

there is a 3 ft crawl space under floor joists.

Thanks.

Screws? Could you use plywood and gypcrete topping instead? That's pretty common.

Just nail it in. 22 GA is really thin.

Never, but never question engineer's judgment

Screw it, otherwise you will get TERRIBLE squeaks, like fingernails on a chalkboard.
