   This would mean that your max joist length would be about 12 ft span....correct?

   And I do not remember ever seeing any I-Joist listing smaller than 9"(+/_) listed in any manufacturer's spec sheets.

   Gene,

   So what's the problem with going with a slightly deeper I-joist?  Are you trying to match existing conditions?

   By the way, I saw a drawing you posted regarding a truss design.  What program was used to create the drawing?

   I use Cadkey 97, a fully-functional 3D mechanical design package.  Pretty much the same features as AutoCad.  If I was going to do residential design work regularly, I would buy one of the newer pieces of software.  Chief Architect comes to mind.  Here is a rendering of a version of my deckframe, sitting atop main floor structural and walls.  Disregard the second copy, as I mistakenly loaded the file twice.  Regarding the I-joist issue, I think I will redesign using light-duty 9-1/2" I-joists spaced at 19.2".

   Nice picture. Don't forget to layout your plumbing drops.............(-:

   I think there were initially 7.5" I'joists and beams out there. But they never caught on - Not enough demand. So I don't think you're likely to find any now.

   BTW - On your drawing, it looks like you've got some awfully long cantilevers at the corners of the building. Make sure you check out the I-joist specs if you're doing cantilevers.Q: How many Microsoft phone help technicians does it take to change a light bulb?A: Please hold, your call is important to us.

   Boss,

   Your right about the 7-1/2" I J's, I used them about 8 years ago for a garage ceiling on a house that I framed.

   I haven't seen them since.

   Boss as I'm typing to you right now the lumber yard just called me, he's saying a company called Jager Industries might have them. I'll try this website.

   The website is jagerind, but that just redirects you to;

   http://www.jager.ca/

   CORRECTION that leads to their home building division.

   Here is the link to their engineered wood products.

   Gene,

   You may want to call Nascor in Calgary. They manufactur a 5 1/2" and 7 1/2" I-joist that is incorporated into their all panels. Not sure if they would just well you the I-joist. (800)792-9555 or (403) 243-8919.

          the only serious cantilever seems to be in the front left corner where it looks like he has a footing for a post?

   Those front two corners have columns under them.  16 x 16 stone ones, sitting atop piers.  The flush beams shown at the far end are bearing walls, and it is one of the places where I could use full length 27 footers, if I can find a 7-1/2" I joist.

   Thanks for the reply, Gene.  Drawings look great as usual.
