I imagine there would have been an order of magnitude 'is this possible' engagement where the engineers said yes, it would need x, y and z and the architects then went about sketching what that might look like.

Maybe Holborn's real proposal was the arguing it caused along the way...

But how many hotels really need swathes of interior column-free space?
How big are these hotel rooms?

This is what they said about the columns

This steel diagrid-pattern exoskeleton serves a critical structural function — not only is it an aesthetic feature, but it also supports the tower itself, eliminating the need for internal structural columns aside from the elevator cores. By transferring the building’s weight to the exterior frame, the design significantly increases usable hotel floor space, enhancing overall efficiency.

“This gives you flexibility in the floor plate. If you wanted to put columns in, a building of this size would reduce your net to gross substantially. You wouldn’t be able to fit many hotel rooms,” Henriquez told Daily Hive Urbanized during the interview.

“If you look at some of the taller buildings in the world, their amount of usable space sometimes struggles. That’s why the exoskeleton is the answer for this because we wanted to make sure that we had all the elevators we needed to service the hotel, the public observation deck, and the conference centre, and then also at the same time provide some lobby area that isn’t filled with a gazillion columns.”

How skinny is this tower that it doesn't need any columns in between the elevator core and the exoskeleton?

You're free to make your judgement based on the initial proposal:

I think it's worth noting that only the northwest tower is proposed to have a concrete exoskeleton, you can see the support columns in the southeast towers.

The initial Daily Hive article said the exoskelton would be steel.

[officedweller]

I suppose that if they did have columns for a tower that tall, the thickness of the columns in the bottom part of the tower would far surpass the massively chunky columns at Shangri-La.

[jollyburger]

I wonder if the floor beams will be steel?

[VancouverOfTheFuture]

grrrr. i hate they arent closing that laneway down.

i hate they arent treating this as one massive property, with shared parking garage/entrance/loading, and instead doubling the amount of entrances for cars/trucks going across sidewalks.

so annoying.

[jollyburger]

Henriquez explained that they are unable to completely close the laneway; while most of the vehicle loading would occur within the underground facilities, the laneway — which includes a dedicated drop-off zone — is needed for the coach buses that can be expected for the substantial hotel and public observation deck attraction. As well, the laneway is required to service the retained 1926-built, eight-storey office building at 570 Dunsmuir St. — a small lot at the northwest corner of the city block that Holborn Group does not own, but would be orphaned by their project redeveloping the rest of the block.

I'm actually surprised that given the fact the laneway is remaining they're not planning on having the parkade entrances front onto the laneway.

[officedweller]

Could be that entering and exiting the laneway would be difficult for larger volumes, esp. since Georgia is so busy and 2 way.
For either Dunsmuir or Georgia, cars exiting the laneway would have to travel westwards.
Using Richards and Seymour, cars could go either north on Seymour or south on Richards and then turn west or east afterwards.
Presumably there would be the option underground which exit to use.

But they could have easily created an L-shaped lane with a wide enough radius for buses.
That would have closed off the Georgia frontage like Telus Garden did.

A recently completed drawing of mine. Severely complex to make, took me several days instead of several hours.

Building Page: https://skyscraperpage.com/cities/?buildingID=165343

Vancouver Diagram: https://skyscraperpage.com/diagrams/?searchID=109218413

Is that number of floors right?

[Metro-One]

Awesome! I was waiting for your handy work. All three towers will by far be Vancouver's tallest towers.

I'm curious as to why this one took you so much more time than the average tower drawing?

Great job!

Floor count is correct.

[jollyburger]

It's weird I was just looking at the model photos again and somewhere in the middle (~20) of the hotel tower they have over-height rooms which seem like the conference room floors. It's around 5 levels which matches the conference room levels but they said they were down near the bottom of the tower. And what seems like 15 levels of long term stay on the bottom.

I guess we'll see which group gets prioritized: long term stay or conference rooms

Well, it's rounded instead of squared off. It gets more narrow at the top and the bottom. The crown is a partial sphere. Then there is that pesky datagrid wrapping around the whole thing... On a 1 to 10 scale of drawing difficulty, it's a 10.
