Nice, but unnecessary with these big, but healthy trees.

Those limbs are rather large and brittle, with a less than adequately strong high tie point.

I'm soooooo confused, is it strong and healthy or weak and brittle. Again my point of how others talk jobs up.

A bit of a lesson for ya, bub.....
These are huge but relatively young and healthy black cottonwood. They grow much taller and faster than, say, a plains cottonwood. Their limbs are notorious for breaking off. Strength is very suspect, likely far less than with other cottonwood species. For instance, Norm's tree. If it were healthy, it looked like a walk in the park to rig out..the only thing that would make it challenging would have been the work zone being tight.
Now, both these cottonwood, especially the second tree in my photos, have a few very heavy upward trending limbs that would be very challenging to rig out whole. And, if one were to rig them in sections, using a high tie point, well, said high tie point would very likely not be strong enough to handle the load or swing. You'd have to do a secondary rig point right at the cut.....These techniques are VERY dicey with a huge brittle cottonwood. Health of the tree isn't the issue...of course, if it were dead or compromised, then, two cranes would be a given.
Further, in this state, many crane companies will not allow riding the ball, even if tied in above. So, because many of the limbs need to tied at or near the balance point (normal for craning anyhow) the company that's doing the work felt they would need a second crane just to rig the limbs. Well, as I said, they obviously didn't feel comfortable or didn't have climbers capable of rappeling out to rig the limbs. Which tells me a lot, as both myself and the other good rigger were confident we could rig the brush on the tree in question. Thus saving many many hours of road closure time... and $ to the city. (The other tree, though, has to be craned in total. No other option.)
So call me a whiner all you want....but that is how the job should have gone down...and, I'm thinking you would agree (and prolly would be up to the task!)...though I don't think You or DWH have experience with these trees.......and I pretty danged sure there are no tree species in this country that present this specific level of challenge---I'm not talking diseased, declining, or dead ones, now...but then, the risk level would also be off the charts as compared to most others.....naturally that's subjective, as there are many many different kinds of hazards that develop with declining trees.
Now, if ya wanna be civil, and polite, maybe we can continue....
if not....well I might exercise the IGGY button,,which would be a first on an arb board for me.....but, what fun would it be then
