- Big D Builders, Inc. has seven OHSA citations and has been fined tens of thousands of dollars over the past decade on projects across the Treasure Valley.
I'm a heavy equipment operator and run most heavy equipment... except cranes. I have always avoided crane training. Too dangerous for me.
I have built shelf roads in mountains, I'm not afraid of heights, just afraid of cranes. One small miscalculation can end in tragedy. A little too much wind, a wrong weight calculation.
Everyone is always in a hurry. Being in a hurry and cranes do not mix.
I'm going to go out on a limb and suggest that nearly any major construction company that has been in business for some time is likely to have had a few OSHA violations over the years. The question is whether they learn from their mistakes or keep making the same mistakes over and over again? (Yes, I know that someone will jump in here and mention some particular company that has never had an OSHA citation, but that is the exception, not the rule.)
Killed 10% of the crew, unreal!
No expert here but looks like the plates welded to base of the column broke and some of the bolts snapped, could it be possible that girders started moving like flags due to the wind?
Lots of things are possible. What isn't clear is whether the damage you are seeing was the cause, or the effect, of the collapse. OSHA has been on-scene since just after it happened.
Looks like the welds held up to me
@@TheRealScooterGuy The one picture close of the base plate had a faulty weld. part of the weld cracked and snaped clean. Torn steel is jagged. only the last quater of the weld looks to be torn.
@@Herecomesthethruth There is something called the heat affected zone in welding. The crysltal structure next to the weld becomes extremely brittle. Using to much heat creates Martensite(strong but brittle) in the heat affected zone. If the structure move a little in the wronge dirrection it just snaps. You can have a strong weld but a weak pillar.
Bet they didn’t have x bracing in walls and roof during construction couldn’t handle wind
Sure it did you can visually see it.that obviously wasn't the issue
Bracing...??? How would bracing have stopped this collapse...??? It's a span failure, not a longitudinal failure. I see plenty of inter-beam bracing in the footage, & that's almost certainly why the entire building collapsed as one. 🙄
Union or non union contractor?how competent were these iron workers?
Idaho is a "right to work" state, which means that the unions have no teeth. Only governmental employees have decent unions (police, firefighters, teachers). So odds are, there were no unions involved here.
Just a mention, The huge hangar at Lakehurst N.J. was built in 1921.Still standing after a hundred years.🤔
Inland crane service and big D, looks like an accident waiting to happen…
If OSHA had all these violations why were they allowed to go ahead and keep building.????
People complain about OSHA, don't follow the rules, and then someone dies.
OSHA guide lines are written in blood.
LOOK AT THAT TWISTED MESS.ITS TO THIN.RECYCLED METAL.TIN? NO WONDER IT FELL DOWN.
Sounds like workers should have vern cleared during lift
Hire union trades workers!
Blah-blah-blah...All you union boys said exactly the same about the Hard Rock Hotel collapse in New Orleans, & the court trial jury late last year found the non-union contractor was NOT to blame...
OSHA violations did not cause the collapse. Terrible engineering, not to have side supports, to keep the beams from buckling sideways in the middle of the span. Engineers may be smart, but have no common sense at all.
Are you familiar with pre-engineered metal buildings ? I am. From what I see the main frames were standing. The secondary framing is standing. Large, clear span structures have been built for many many years, and the engineering is solid and reliable at the end of the day, You will find most likely it is not the steel, it is not the engineering and that it was human error in the field.
@@craigwheeler2057 I tend to agree with you but to not have sideways support is a problem. Major support. Was the lack of support causes by engineering or contractors? Who is responsible for that?
The collapse looks inward. Could it have been a cantilever connection?
@@Sarconthewolf the main frames are the sideways support. It is not uncommon to have a rigid bearing frame and a open end wall for a hanger building. It could be that the end wall will have sliding doors that had not been framed at the time of the collapse. The roof purlins & wall girts appear to be substantial enough to keep the main frame stable.
Based on the inward collapse from the center could be from several factors. To early to speculate from my vantage point.
@@craigwheeler2057 I agree, but couldn't they have a, temporary brace, say going from the ground, on a 45% angle, to the top of the beam, to stop any movement in the center? That to me would have prevented the side buckling that is so obvious. But, I could be wrong and I'll wait to find out the cause.
manufacturing is back to USA !!!
You mean Israel. USA is owned by Israel.
