Timber Condition for Structural Application

[psychedomination]

Hi there, I am working on a project, where the client would like to hang an exhaust hood from the timber floor joists.

I've done a capacity check of the timber floor joists and they are fine for this application (the hood is only 450lbs and this will be spread between 2 joists).

However, when I went to the site, I noticed that one of the joists (not one that will be used structurally) has some splitting at the bottom. I'm not sure if the other joists have this issue but latent.

Judging from these photos, do these timber joists look suitable to structurally support an exhaust hood?

I'll try to visit the site tomorrow to inspect them a bit more but is there something I should do on site to verify their adequacy? Any concerns I should be focusing on?

The joists are 2x12

N.B the joist with the notch in it won't be used structurally and nor should the one with the evident splitting on the underside. Mainly concerned about the condition of the rest.

I don't know much about timber, but that all looks quite mouldy. Mould alone is probably no problem, but there could be some dampness issue down there?

To me, the joists look like they're in reasonably good shape.

Places where a nail or screw caused a chip or splinter locally shouldn't be a problem. There is one joist, however, that looks like it is a little more than localized. That's the one I'd be concerned about. Could there be a termite issue? Hard to tell from the pictures.

I agree with the other gents. I'm not concerned about splitting but would definitely be concerned if we're seeing mold here.

Other than the mold, which should be remediated regardless, visually the joists look okay. I would break out the phillips head screw driver and probe for soft spots.
