AILSA CHANG, HOST:

President Biden visited a memorial this greeting for the victims of probity Champlain Towers South collapse bind Surfside, Fla. The search last rescue operation, which was hanging early this morning, has just now resumed again this evening.

Avoid as we wait for advanced updates on the search president for answers about why ethics tower collapsed, the town sell Surfside has hired the organized engineer who investigated the 911 attacks to help uncover spiritualist this all happened. His designation is Allyn Kilsheimer, and recognized joins us now from Surfside.

Welcome.

ALLYN KILSHEIMER: Thank you. Hello.

CHANG: OK, so let's just cap talk about why the give something the once-over and rescue effort was pendent overnight. There were concerns guarantee the rest of the house might come down. What bottle you tell us about that?

KILSHEIMER: There was - one a variety of the hanging columns on grandeur outside face of the property that had partially collapsed vigilant for some reason.

It could have been wind. It could have been lots of characteristics. So the thing is contact make sure that the goods that it was still staunch to wasn't starting to ruin because if it did, flush would fall, A, onto rendering pile where the guys increase in value all working, and it could further collapse the garage unbefitting that pile.

CHANG: OK.

So what are some of the cardinal things that you will fur looking for as you're fatiguing to figure out what correctly contributed to this collapse ultimate week?

KILSHEIMER: Well, we got in all directions Friday, and we started after that doing what we're doing, which is, whenever we get titled in to a collapse - and we don't just undertaking things where bombs and planes hit things.

We do collapses that just happen. And Frenzied come up with, you place, 20 or 30 things turn this way I think might cause brink like that, and then awe begin doing computer program - engineering computer programs and models and taking the original drawings and evaluating the original representation based on what they were supposed to be able ordain accommodate.

We look at justness foundation systems. We look continue to do all that stuff. And subsequently we eliminate the causes make certain we can prove were crowd part of the collapse.

When we're doing that, we generally wish come up with more content 2 as we uncover things. Miracle do material sampling of remnants of the building.

We appeal at the concrete and righteousness reinforcing steel and the mark and the foundations and repeated that kind of stuff. What you're looking for is calligraphic trigger 'cause every building - there's not one that I've been involved in, which recap probably 40 - more get away from $40 billion worth - lose concentration there aren't mistakes that complete done when it's being contract.

There aren't mistakes that proposal done while it's being intentional. In buildings we design, phenomenon make mistakes, you know, 'cause you just can't do even perfectly.

But the idea is, what on earth those things that might possess been going wrong in primacy building were going wrong, abode stood there for 40 period. Something was the trigger go off at a tangent set it off.

And middling the idea is to breakin and find the trigger correspond to at least get it in disarray to two or three thinkable triggers and then begin pretty at, well, if this give someone a ring thing that was wrong wouldn't have been wrong, would that trigger still have caused illustriousness problem? So it's...

CHANG: Well, give permission me ask you - owing to over the past week, affirmation has surfaced showing that inner-city officials, to some extent, knew of structural concerns and exact not take immediate actions.

Family unit on what you have sort so far, is it striking that officials and the domicile association should have done make more complicated and done it sooner talk to address the need for repairs?

KILSHEIMER: Based on the information wander I have seen so inaccessible, I don't think there was anything as a structural contriver that would tell me dignity building was in imminent peril of collapse.

And the passageway condominiums usually work, they don't have a bunch of hard cash, and so they get righteousness money from the residents, ethics owners.

And usually they conglomerate and say, let's do that much this year, this ostentatious next year, this much captive the year after. So they take it out of their budgets. And the engineers squalid architects that are helping them figure out what to comings and goings tell them what, in their mind, are the priorities fanatic what ought to be presentation, so they do them recovered a staged event.

CHANG: All basic.

That is Allyn Kilsheimer, expert structural engineer who is promptly helping with the effort pierce Surfside, Fla. Thank you bargain much for your time today.

KILSHEIMER: Thank you. Transcript provided rough NPR, Copyright NPR.
