Team Visits Quarry to Select Materials: #BuildKCI team members recently performed a stone inspection at the Phenix Quarry in southern Missouri. Polished limestone panels will be used as facing material for the west wall of the check-in hall in the New Terminal at

Context?

Guess the back wall of the headhouse is going to be limestone. I don't hate that decision and it's not the puke fake beige.

And locally sourced. A very high grade almost marble limestone from mines north of Springfield that had been abandoned for half a century recently reopened.

Yeah seems like a cool choice. Seems like the public doesn't get much insight into all this. The progress outreach has been pretty poor overall.

Use of local limestone for the head house was a choice announced long ago. I think it may even have been in the public open houses. I am 100% sure its been noted in city council presentations since 2018/2019.

I do remember that but I didn't take that as a final announcement given the level of VE that was expected. For example the fountain mentoned isn't going to be as described.

I wonder if the prefab concrete panels are recycled concrete from the old terminal?

Not a chance. Once the cement has cured it's done and can't be separated back into it's original materials.

They probably are using the old concrete for road base material and building up embankments and such.

It's not about making new concrete, it's about transport costs. It's like dirt, you don't buy dirt for a project, you buy the labor to move it. So reusing on site concrete as fill cuts two costs there.

This latest cold snap was perfect karma to that kind of shitty engineering and project scoping.

What are projects like this normally using for insulation in a climate like ours? Serious question, I'm honestly not familiar with the latest insulation techniques.

Hard to say for certain, as we don’t have up close pics, but that insulation material looks far more like mineral wool than it does standard fiberglass. It wouldn’t surprise me either, as mineral wool is regularly used in commercial applications far more than standard fiberglass.

Or Rock Wool

The picture on this site is a close match to the terminal picture.

What makes me think it's not fiberglass is the lack of fluffiness. The outer edge of fiberglass is always undefined so you don't get a straight edge. But that material has a sharp edge.

You are definitely correct in that. Those are the same product, same process to manufacture as mineral wool but a different material makeup, both have the same texture though. Regardless, significantly more efficient insulation than residential grade fiberglass for sure

I can't believe this site is still free!

Closed cell foam. Typically sprayed in application. Quicker, easier, and thousands of times more effective at the same or lower cost as any vintage product like rock wool or fiberglass.

Spray foam definitely isn't easier.

You can teach a 10-year-old how to install battens and if you mess up you remove the batten and put a different one in.

Spray foam requires a large up front preparation to protect outlets and you have to clean up mistakes after it hardens. You need to have some clue how to spray it properly accounting for layering depending on the product.

Even more important, you can't install it below a certain temperature in many cases. Some products it's 40 degrees and above air temperature.

It's possible they are using both.

I’m sure they know what they’re doing

We got ourselves a good old fashion insulation off!

A FAA rule change in the closing days of the Trump Admin will allow airports to use PFCs to pay for transit lines to them. KCI would be able to contribute to a LRT line to the airport based on % of airport ridership expected to use the line. However, I expect them to be tapped out when it comes to PFCs due to the new terminal. The next big change at FAA will be to increase the PFTs, which like the gas tax, have not increased in over 20 years.
