Potential Floor Joist Issue in 2 floor garage

[mbga9pgf]

We have recently purchased a home with a lovely, recently constructed 2 floor garage (games room upstairs).


Anyways, it looks exceptionally well finished, good roof, velux windows etc. However, my grandfather pointed out that the floor joists for the upstairs floor are not "joined" using typical metal plates and bolts, instead, are joined mid-span with that thin steel corrugated punched plate (metal gusset?) that is more typically used in the a frames of the roof. I will try and get pics, fortunately, there isvery little in the way of loading upstairs so not too concerned. However, if I wanted to sort this (if it is indeed a problem), I take it stall plates bolted to join the joists would be the way forward?

I think I know what you're referring to and I was on a job where the builder (who did a runner with the clients' money) joined floor joists in the middle. I went up onto the first floor, stuck to the sides but it was too late... the first floor gave way and I very nearly fell through with it!!!

Joist spans are there for a reason.
