Ac is 2022.

That is what I heard. Chiller lines are an issue right now. Going to take some time to figure it out.

It appears to be a gorgeous day in the Hill. Walt must agree, as he’s just taking in the view without moving a muscle.

Not just the chiller piping. There is no chiller to support.

Fellas let’s be careful what we write... my crafty 7-year old occasionally peeks at my phone.

oooof that’s a big L

Heat would not be dissipated by simply static open windows or doors, without the dome being pressurized thus forcing hot air out and replacement by intake of cooler air no cooling would be accomplished, and heat would continue to build up internally. They may have some alternate plan for this, I just have no idea what.

I would think this is only effective when the opening is at or near the top of the stack, this would not be the case in this building. The original design called for forced air exchange, and without that I do not buy that enough heat will be dissipated by temperature differentials, especially so when outdoor ambient is already very high, as it usually is in September for games, summertime forget it.
I assume they could repurpose the air handlers from dome support, to exhausting air from the building or with AC to going through the evaporator to chill the building.
Industrial chillers could be located inside or outside the building itself.

It's 2:40 on Thursday. A crew shows up in Walt's yard and the white crane is in operation, ( I should say he did a 180 and now is stopped). Whatever could they be up to? The white cranes op is in the cab and has just lowered the boom down closer to the box girder and spirals. C'mon boys do something! Now it's quitting time for a regular day and a crew of eight just walked across the yard and left for the day!? They must have been working on the far side away from the live cam?

Damn the bikini ads went away and now I'm getting ads on laminated Trusses.

waaaaaaiiiit a minute, Santa and Rudolph aren’t real?

Santa is real and he has the same wristwatch as my uncle!!!!

You know golf and football seasons are over with when several of us are stalking this thread for updates as if it were NSD with multiple coinflip situations for higher profile recruits.

While this is exciting as hell to see what the end product will look like, I'm already clamoring for spring camp updates.

Another day where seemingly nothing of substance happened. At least there were a lot of people walking around.

I saw some activity on what I believe is a hydraulic lever that controls the angle for spiral columns for the back stay yet to be installed in the middle of the western face of the building.

That might foreshadow installation of that back stay sometime soon.

Or maybe not. I remain surprised and perplexed by the lack of progress on the crown truss since what, before Christmas?

Me too, you can't ask for nicer weather in January than what we had today

They might have to make sure what's already installed is completed, stable, and able to take on weight before they install the rest. It's not as simple as it always appears to some of us.

If so that would indicate an unforeseen problem, would it not?

They actually took that hydraulic level off today. No idea why but going backwards can’t be good.

Hope to see positive movement tomorrow.

 

[Moontan]

If so that would indicate an unforeseen problem, would it not?

Not necessarily. Would be consistent with a “trust but verify” viewpoint. Something that’s done in software development organizations. A developer may claim that a bug is fixed but there will be plenty of tests performed (using various scenarios) to validate the fix.

 

[bnoro]

If so that would indicate an unforeseen problem, would it not?

I wouldn't say that at all. In a situation like this where you're building over an existing structure you want to exercise a good amount of caution to make sure the weight is properly distributed before the entire ring is complete.

The concept of the crown truss is that the forces pushing inwards are distributed amongst all the supports, but currently it is pretty much being distributed on what's currently up which is far more stress than when the project is completed.

All of that is true however before starting this project projections and calculations were done saying it should not be a problem, and projecting the crown truss would be done by end of January. It is becoming obvious that goal will not be achieved, now maybe adjustments to the schedule can be made to keep the project on track, but to me it suggests that they have run into some kind of problem(s), and wasting all these good weather days does suggest something is not going according to plan. Just my opinion.

"projecting the crown truss would be done by end of January"

We don't know what the actual timeframe was (as you said, it's your opinion), so why worry about it?

There may have been 20 workers providing crucial services on the crown truss all day, just because they aren't lifting anything doesn't mean that there wasn't any work done. Until a contractor or Pete Sala says we're behind, I think we can assume we're on schedule.

No not on that, that was the projected completion date of the crown truss. My opinion is they have some kind of problem. I do not know what and as I said they may be able to adjust to get back on track, KI think they logically left some wiggle room because most projects run into something unforeseen, we shall see.
When did I ever say I was worried? No skin off me. What is it they say about assuming?

I have to agree. Ther is no way those time frames are getting done at this pace. They’ll be lucky to have the crown down my mid summer working like this. Wonder is there is a shortage of material or its not coming in the correct order.

You are assuming there is a problem

 

[JRHEETER]

I’m going to assume there is a slight problem as it seems like everything has halted for the last week plus.

Could it be possible that “time with their families around the holidays” was scheduled too?
