Thanks everyone for your input.
@XR250 TBH I did not even notice the bolt specification until you pointed out. This is a steel supplier, and they specified their typical bolt type. I only specified sizes through email, and they prepared drawings. Good point, I will pay more attention next time...
I specified one bolt ledger to support this steel stringer, since there is not enough space to add another bolt (8" min distance reqd. at brick wall).
The steel stringer is also supported on the LVL beam through bolts. GC did not want to add bent plate to bear on it since they didn't want to...
It's a 4 story above grade; so, IBC. Open front structure never really worked for any of our projects so far. Arch wants open space; they don't give us any interior stacked wall to help us. On other hand, GC always complains why we did not use wood wall instead of moment frame. So stuck...
I know what you mean. But we still have to compete with them for projects. If even bigger companies don't really ask them for much, it is difficult to convince clients why we actually need them. The argument yesterday turned how I dont't know how make the structure optimal just using wood...
They are all individual owners. No HOA or any collective organization; they can modify or even completely raze as they like. So, it's the individual structure. It is designed as individual.
Not sure how others get away with it. I have checked someone else's calculation for similar case of wood...
I am not very familiar with residential buildings and wood construction (only been working in this area for 3 years, so forgive me if the answer is so obvious). This is what I have done for a single-family row house rear and one-story addition (20'x50'). For the short side, there is not really...
Thanks Celt83. The owner is willing to make it right as long as they don't claim anything excessive for business loss in their restaurant or make absurd demands.
The contractor had pictures of it just hanging in the air before razing the two story wood building. My crude guess is that it was...
Thanks everyone for the input.
I am going to stop updating on this post since I feel like I gave out too much info than originally intended and it is likely going into legal dispute.
Just so I don't leave everyone on a cliffhanger, here are a few pieces of information came out of the meeting:
GC...
I do agree with your points. Thanks for giving me bullets to use during the meeting.
But again, I do not believe the contractor removed the support. The contractor is a well-known and highly skilled one; I was very surprised they even took this small project. Likely the client had a connection...
I am just assuming for the sake of staying calm.
Properly poor choice of words, I meant to say it's not a dangerous condition created by our contractor. I believe it is a pre-existing dangerous condition that just got exposed.
We don't have the privilege of leaving space between buildings...
Yes, understood. I am not saying the current condition is enough. Agreed that it needs to be supported /reinforced. But I think it has been like this for so many years, so likely not a dangerous condition (hopefully overdesigned joists). Big assumption: the contractor did not remove some steel...
Thanks dik
Oh my bad, I just saw a general discussion forum and clicked on it to write the post in a hurry before my lunch.
The way I see it (of course I will get more insight after the site visit), they likely added an additional bearing plate at the masonry wall to install it; probably...
During the demolition of the wood building to prepare for a new podium construction, the GC discovered that a steel joist from the neighboring building was encroaching into our property.
It appears the joist with bearing plate just hanging in the air. My guess is it was fabricated to a wrong...
Thanks kipfoot. I believe they have already started working on it. That is a good idea; but not sure if we have enough space to provide a base plate to connect the HSS to wood beam below.
Thank you for reading my post! I appreciate your time.
