Hello Kathy,
Not that specifically, no. As a matter of fact, I have used structural steel stud framing for some Single Family Residential from time to time: on a house of my own in Florida, and for a structural engineer who was a client of mine in Pennsylvania; that is under construction right now.
However, I have recently read, as a CEU, that wood stud framing can be taken to taller heights than ever imagined before. I still have grave concerns about that in terms of fire, mold, rot and infestation.
About contractors suggesting changes in materials to owners, this happens all the time. It is usually started by the Client. They get shocked by the pricetag of their project when it bids (no matter how reasonable that might be), then go to the low bidder and tell them they'll give them the job if they can cut out several tens of thousands of dollars or even hundreds of thousands of dollars, or more. Then, the contractor, wanting the job, proceeds to see where he or she can cut and hack into the project to comply with the owner's request.
In the process, many things can suffer, particularly interdependent features in the design that might not work properly after willy-nilly hacking. But this happens all the time.
To try to help circumvent this in my own practice, several years ago I implemented a Base Bid + Owner Optional Upgrade approach. This puts all the most economical methods of constructing the project (within reason) into the Base Bid Package, then lists up to 10 Options (Add Alternates) that have may of the goodies. In this manner, on the Come to Jesus day (Bid day), hopefully the client at least sees the Base Bid as a reasonable number and has a viable project. Then, he or she looks at the Options like an ala-carte dessert menu, and can see what they might want to sweeten the project. This is more of a pleasant additive approach, rather than a cutting approach (which is always more painful psychologically). This approach requires more work on the part of the Architect to plan these options and construct the specifications properly, which is where this information is usually located, along with the Bid Forms.

Many of you know I am working on a research project for the Steel Framing Industry Association. In recent telephone focus groups, we've learned that it is not uncommon for contractors to ask either owners or their agents to switch materials. The example we've heard is that some contractors will lobby for wood framing instead of light gauge steel framing in mid-rise commercial buildings. Has that happened to you?
