The funny part about this framing inspection was that the AHJ was just leaving as I was coming in after he just approved the frame. He was outside talking when I came out of the crawlspace to show him this photo. Needless to say he had to get his paperwork out again.

That's one of the funniest/stupidest things I've seen in a while. Haven't seen you around lately - hope it's because you just have so much work! (Used to see your posts over at the ASHI site a couple of years ago - I'm not there anymore.)

I see that crap fairly often. The builders always respond with, "Wood shims are to code."

"Dimensional wood shims," I have to tell them.

The wood shim allows you to adjust the main beam for settlement as the house gets older. I will look for and try to post a photo of the one I have that used a car jack for the same adjustment.

And you are guaranteed settlement if you concentrate the load of that girder on the side of a wedge-shaped shim with a bearing surface about 1.5" X 1/4". In fact, you'll be lucky if the shim doesn't squirt out the side due to the load. It doesn't even appear to be tacked in place.

And that doesn't even address the unsupported joint on the girder. Why is it so hard to throw full length scrap lumber on top of a pier to spread the load? This kind of crap is why I got disgusted with building homes.

While the shims are problem, I'm more concerned about the beam splice without any support.

The issue is a splice with no support and lack of adequate support on each side of the splice. Since they are using wood, a minimum of 1-3/4" would be required on each side of the splice. We are an IRC state and this was new construction.

Jeff,

Can you refrence the 1 3/4" bearing from the IRC. I know the NJ edition is a 'modifed' IRC, but I can't find it in the NJ edition.

I was told a wood beam splice 'may not' require any support if it was designed and constructed that way; obviously, your picture is not that type of a splice.

NJ IRC

R502.6 Bearing. The ends of each joist, beam or girder shall have not less than 1.5 inches of bearing on wood....


A splice is really not 'the end'. Beam splices and supports should be designed by an arch or an PE.

Of course in older homes, as long as a post/column is supporting a splice, it's aceptable.

I once had another inspector say a top plate is not required on a lally column; this was after he missed that fact and the column had cut into the beam about 3/4 inch.

1.5 inches not 1-3/4 like I stated. I recently used an LVL that required 1-3/4" end bearing and I just had a brain fart.

The beam must be continuous and where there is a splice, it must be supported.
