What a D.A. All that trouble for 43,000.00 ? What a rube!
"Sound Transit became aware of the altered reports by comparing Appleby's submissions with reports from his supplier, Oregon Steel Mills, which showed they supplied Grade 36 steel."
Did the guy think that he would not be audited? Sheesh. And yes, he should be in prison, it's this type of fraud that costs innocent lives.
sad thing is, that they didn't find out until everything was built, and now the engineers are saying its still safe. I hope that don't lead to any leniancy on the guy!
I heard the only reason they did get audited was because another contractor couldn't get grade 50 in the quantities used, and he questioned where they got it all!
most likely still safe due to the very large safety factors used in the conservative designs of things like public transportation, i would be surprised if the steel was the weakest member in the design, but then again i'm not a P.E
either way that's fraudlent abuse of the system for private gain and he does deserve some jail time
Wow, could be another insensitive issue :).
Well, I'm interested to watch the hearing in youtube :).
Mabe some one could help me. Is there such a thing as Grade 36 rebar? I have seen Gr. 40,50,60 and so on but never Gr. 36. I have also seen A616 Gr. 40 or 50 for rail but never Gr. 36. Where am I missing it?

DBA: Deformed Bar Anchor - ASTM A496
Typiclly welded to a substrate using the Stud Weld (SW) automatic process. In building construction they are usually found on perimeter slab edge bent plate that cantelevers a substantial distance over the perimeter beam, or occasionally on embed plate assemblies where some tension may be expected to be developed.
The grade 36 material was used in the casing (steel cylinder rolled from plate) that surrounds the reinforcing steel. This is likely why there is no need to go in and reinforce anything. The load is bearing on the reinforced concrete. The steel casing may have been to add seismic reinforcement, something you may have noticed in seismic upgrades to older reinforced concrete bridges.
Bert70,
My bad. I misuderstood the article to be talking about rebar and after I read it again It is not talking about rebar at all. Thanks for clarifying that for me.
