What a find THAT would be… !!!

[NFHale]

That makes a ton of sense… That’s why we build a building now and it’s falling apart in five years

[NFHale]

One wonders how many workers (probably slaves) died making that dome…. As well as other Roman structures, like the Colosseum, etc..

[central_va]

According to the article the skilled contractors were indentured or outright slaves and the unskilled workers were free citizens.

[NFHale]

Probably had a fairly large death toll during construction… Probably not on the same scale As the pyramids of Egypt… But still…

They didn’t care about lives, Free or otherwise

[central_va]

I doubt construction workers were mistreated.

[SunkenCiv]

I want one.

Better Roman houses had the conpluvium in the atrium, with the impluvium below to catch the rain running off the roof. Good design choice, other than in much colder climates. I wonder if the Pantheon's oculus was an analogous design choice.

Heh, if ya gotta. 😁🐟

Sorry. It’s on backorder

[ApplegateRanch]

So you used to drive I-84, past Boise, too?

[rlmorel]

Haha same thing there?

[Locomotive Breath]

The most modern rebar has an epoxy coating to keep the water from getting to it.

[ApplegateRanch]

Yes, it was. Years spent on about a 1-2 mile project, with several miles of cones & lane closures.

Rebuilding an interchange.

PoF “Down the rabbit hole I went”

Sunkenciv is wicked that way as instead of posting meaningless and inane articles, he posts deep and insightful articles and thoughtful comments!
I’ve been down rabbit holes after reading his posts too!
