I-35 / US 30 Flyover Progress

This reminds me - didn't something similar occur in the construction of Jack Trice? I was still in HS but remember my dad talking about it - they had to rebuild or re - pour the pillars for the stands? It was all kept hush hush but everyone in the community noticed it - good case study in bad PR management.

We cut funding to ISU in order to pay for the mistakes on building the road to ISU.

If you have ever installed a door you know that is exactly what wood shims are for. No big deal.

Just stuff a few folded up napkins or a coaster in between and call it good.

IIRC, my concrete prof told us the upper deck was deflecting more than the engineer anticipated so they had to do fixes to it.

If you look at the 1st, 2nd & 3rd piers for the exit from 35 N to 30 W while driving eastbound on 30 (with the 1st pier being the one that is actually attached to the bottom of the ramp), the 2nd pier is visibly lower than the slope of the 1st & 3rd piers, meaning the off ramp would have a dip in the middle of the curve. It's clearly visible to the naked eye.

I've seen that lower pier and tried to make sense of it (maybe they could do something to make it higher). Anybody else notice the odd way they have placed some of the bricks (with bunches of the same color)? And is it an attempt at cardinal and gold with the bricks?

If only we had some engineers on CF to FIX IT.

I don't know all of the details but a professor talked about it once and I believe it was something with the type of soil or how much it compacted during or after construction. Someone on here may know more than me.

I say it's close enough. People should just drive over it really fast.

I too was wondering why this is such a cluster. I was down in KC a month ago and the speed they can put these types of bridges up is second nature. My guess is the contractor is in over his head and the DOT is also newer to how to handle these types of bridges/construction projects.

Yeah I believe it was short term vs. long term settlement effects.

Years ago I worked on a construction crew and we jacked up the floors of a parking garage and put shims in. Boy did that look bad on the inside.

Can’t they just mud jack it?

This is a nod to the ABC computer created at Iowa State. The brick pattern supposedly correlates to code on old punch cards that early computers used.

"A special feature of this project will be a historical reference to John Vincent Atanasoff’s invention of the first computer at Iowa State. The bridge pier for the ramp will display a coded message reading “John Vincent Atanasoff invented the first computer at Iowa State College in 1939,” giving much-deserved attention to Atanasoff’s accomplishments."

Like others have said, it depends on who's mistake it is. If I (as the contractor, which I happen to be), make something 36" tall instead of 3'6" tall, then that is on me. If however the designer said 36" tall on the drawings and actually wanted it 3'6" tall, then I'm submitting a change order for extra work and delay, which the state would then be responsible for.

A lot of that stuff is normally caught by the contractor, but beam seats, or top of concrete slab elevations are hard for the contractor to back check, especially for smaller contractors that don't have tons of engineering staff supporting them.

Just don't call any AeroEs. We don't design stuff made from concrete (aka "targets").

Those are fighting words...

 

[CycloneBob]

Not only are the alleged construction mistakes concerning, they seem to be working at a snails pace. Why don't they use 7 days and long hours to make some progress?

Depends on what there schedule and any schedule changes they have. The job schedule (that they are held to) may not show the need.

Long days & 7 days a week is a good way to spend a ton of money and not necessarily get a ton of results. It burns your crews out and if you aren't setup to run that way, it spirals rapidly out of control. Or, the LDs may be less than the cost of paying all that OT.

Yes, because a "coded message" will give plenty of attention to the ABC computer. Of course only people who already know what it is will give it attention...
