Hello everyone,this is my first post but I have been a long time reader on these forums.I am building a ICF home.I am at the point where the walls are up,the roof is on framing is(done).The origional framer contracted a complete framing package including basement stairs.At the point that the concrete contractor came to do the basement floor and the garage floor,they started to set there elevations,the framer who also did the ICF came to me and stated that he wanted to leave and presented me with a bill for the work he had done minus amounts for what he felt the incomplete parts were worth to him.I asked him what the problem was and he stated simply"we have someplace else to go"I felt that the amounts were greatly under estimated and not including the cost of finding someone else to do a smaller part of the over all project.So I refused to pay him until I found these costs.I have since had a framing inspection and found that the stairwell opening was not long enough not enough headroom,and there are 41 floor trusses that are out of plumb by a 1/2 to 15/16 of an inch.I would like to know where I could find tolerances for the installation of Paralell Chord Trusses they are 16 inches deep.The truss manufacturer sems to be a dead end as they have tolerances for 12"-1/4" 24"-1/2".There are many other problems but I would like to start here.

First off 15/16 out of plumb in 16" is a huge amount. Is it a random amount of tilt on each one or is it all in the same direction? IE is it wracking? Is the truss mounted on the top or on the bottom flange? I asume the sub floor is on already? Is it screwed, nailed or screwed and glued. Is there interior framing on top of the subfloor? Is ther any lateral bracing of the trusses? Eric

Thankyou for your response,they are random all over the place 15/16,7/8,3/4,5/8,1/2,3/8,1/4,and 1/8.Out of 96 trusses there are 5 that are plumb.And I believe that was just luck.They are setting in Watkins hangers on the ICF walls the other end on beams and 2x8 material.They are glued and screwed to the subfloor and the framing is on top.

Yes the latteral bracing is in.

Acceptable tolerance is d/50. In your case that would be 16/50 or about 1/4". See page 25 of attached link (page 11 in the document) http://www.sbcindustry.com/docs/06_BCSI_booklet_FINAL.pdf

Well, You are not moving the Watkins hangers, and the floor is glued and screwed so you are not in a good situation with a reasonable way to backtrack and fix. More questions 1. Were the watkins hangers into the ICF plumb and level to begin with? 2 How wavy is the resulting floor? 3 does the roof bear only on the outside walls or are some of the interior walls on the first floor load bearing? I would set a rotating laser level in the center of the structure on the first floor and measure how level the floor is. IF the floor is flat enough, I would be pissed but I might accept what is in place. I figure you have limited options. The first is find a structural engineer and get his opinion on the integrity of it. My guess is it is ok in a structural sense but I would go for a more competent opinion. YOu may have to add additional lateral bracing. The cheapest solution is to live with it. The other option is to tear out the interior structure and start again. IF you don't have to pull off the roof you can likely salvage the interior walls. the floor and the trusses would need to be replaced. IF they were glued and screwed together I don't think you can salvage them without alot of effort. If you were doing it it yourself and had the time, I think you oculd salvage the trusses. Eric

Thankyou,you have been of great help I have the publication you linked me to in my hands.I did not realize the formula part it comes out to .320 less than 3/8 but more than 5/16.The house is ICF all the way up to roofline and there are no load bearing interior walls.A few days before this framer quit the building inspector came to inspect the septic system,at this visit he made a walk thru of the house and forced the framer to comply with some issues with the roof trusses at that time.I believe he knew of these other issues and that is why he wanted to get the money and run.Thanks agian 50cal

I will set up a laser and check the floor.

You might be able to furr it in some way to level it out.  By doing this you won't be messing with the attachment points and risking the structural integrity of the trusses.
