Architecture - Steel Beam in Basement

I am building a new house in Saskatoon SK. It will be a 1000 sq foot bi-level. I want to avoid teleposts at almost any cost. I work in the steel industry so I can get a beam at a very resonable cost but I don't know what size to get. I would not want one that is wider than 14" (just to ensure descent headroom) but I don't care how heavy it is. Can sombody please tell me whether it be by their knowledge or experience what size of beam I should get eg 14 @53. The span will be at the most 35'

Hi Ianms,

For your own safety (and your family's), let me explain some issues, starting with the building codes
As we all know, there is a building code, but each state / province has its own version / adaptation. An Architect, Engineer, etc must elaborate the interpretation / application of the Building codes, calculation of structures and foundations, for each project, etc. Not only for the technical understanding of these issues, but for the liability.
An advice regarding a technical subject (something basic as the beam dimension and independent if you are paid for this advice or not) implies liability.
Structures / materials are quite different depending the characteristics of the project, load, soil / topography, wind conditions and seismic calculations.
Certainly, dimensioning a beam is not a DIY task :)

Can sombody please tell me whether it be by their knowledge or experience what size of beam I should get eg 14 @53

can't do that because i can't interpolate the loading conditions without either seeing it for myself or looking at a full set of plans. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

what that gives you is a starting point and ultimately you would need to get it verified by an engineer. that would be a decent size piece of steel, comparitively.
