I haven't figured out what you've got there. I see a Weyerhauser microlam, and then your red dot. Not sure what the stuff between those two are. It actually looks a gap. What's up with the microlam, is it supporting those joists?
Yes it was a manufactured house. Here are some additional pictures. The first picture shows the support beam before the house was set. That is the support beam in the first pictures. To the back of the house there are support posts every 8'. The beam was used so in the front of the house we would not need a support post.I'm trying to figure out why you've got what looks like a double rimboard in the middle of your house sitting on a flat 2x10 that is supported by flat 2x6 shims spaced at 4 ft oc over the central beam. Is this one of those manufactured houses that comes in two halves that are joined together on-site?
Sorry to sound ignorant but what is a "rim joist"? So you are saying that the bottom of the prefab should have been sat right on the microlam (center beam)?Important question: is the joint between the two sides sitting directly over that microlam? In other words, are the shims supporting both rim joists?
Also, I would have a real problem with this, if this was my house. Somebody didn't do a good job. No reason for a 3-1/2" gap between the top of the microlam and the bottom of the prefab structure. Somebody screwed up. Did it pass inspection?
The beam is in the middle and it supports both both sections of the house. I know that much. The angle of the picture makes it hard to tell that.Build, the inspection is not for the hole, it is because that is a lame way to connect the floor system together over a bearing beam. The Inspector would be from the Building Department to OK the building for final occupancy. The mess you have would not pass inspection. To back fill an 8' basement without bracing inside as they did is not to the minimum safety code. Without braces, the fresh concrete walls could easily crack from all the dirt (clay) compacted from the bobcat).

The beam appears to be about a foot in the wrong location. It looks like it's only holding up this side (picture side). What is holding up the other side of the mod's floor? Another beam? Be safe, G
Good catch.To back fill an 8' basement without bracing inside as they did is not to the minimum safety code. Without braces, the fresh concrete walls could easily crack from all the dirt (clay) compacted from the bobcat).

This is my humble opinion, but I don't think the building inspector will want to bless a hole there if he ever knew the company that manufactured the structure told you to call the inspector for his blessing. I think the inspector will want something from the company saying it's ok to make a hole through the marriage line there. The inspectors in my area wouldn't make that call. (Put it this way, I had to write a letter last week and seal it with my stamp to bless a contractor's idea to go from 1/2"x3.75" wedge anchors to 5/8"x7" chem anchors - obviously a safe bet, but the inspector wanted zero liability.)If a home inspector can't tell us if it is safe to make the holes in the joists then who should we contact?
