I was down there Friday afternoon. That thing is REALLY loud.

They always are. I hear one - not this one as the one I hear has been working on and off for a couple of years now - far away from the harbour. Not sure where it is.

I like this rendering from the Queen's Marque website - http://queensmarque.com/. It looks impressive, and seems to be the only building in the downtown with power :). Everything else is blacked out.

Although Queen's Marque won't be extremely deep with 2 parking levels below ground, the excavation will cover a large area. I wonder if the dirt excavated will be used to create the piers? It would certainly speed the excavation if the excavated dirt could be dumped into the harbour as fill for the piers.

It would be great to see concrete footings poured by the end of the summer.

I think whatever is excavated will be trucked off site, I believe they have a containment cell in Bedford for the material from the harbour floor. Most of the waterfront is built on rubbish and is not suitable for building large structures on. Dexter has already trucked in a lot of engineered fill to build a solid base to drive the sheet pile coffer dam from. The boundaries of the sheet piles will probably show the limits of the concrete foundation, so I believe the piers will extend beyond this on piles.

Thanks for the information. It will interesting to watch this one being built.

So that sheet metal they're driving in is a coffer dam? How does that work? Are they driving it into earth? Or bedrock (is that possible)? And then I assume it holds out the water so they can pour concrete? Does it get removed at the end of construction, or is it just worked into the final construction?

it probably goes down to bedrock. will be tie anchored back as they dig down. that area is all fill and seabed, so likely pretty unstable. Someone told me that the Queens Marque parking garage is watertight, and would actually float without the building on top holding it down.

typically they cut it off a few feet down and leave it there.

Bishop's landing was done similarly and also water tight, I had heard they did a type of leakage test to ensure that no water would get in. I am impressed with how quickly the sheet pile went in. I think they have been working 6, maybe 7 days a week.

Large caissons are on site now, I could see them being the supports for the pier sections.

I heard a similar thing. And because of this it will take longer to build as they actually have to build two foundations. One that sits inside the other.

Some of the Queen's Marque construction can be seen on Nova Scotia webcams - https://www.novascotiawebcams.com/en...s/cable-wharf/

I'm sure many of you have seen these renderings but I had not so I thought I'd share...

I hadn't noticed this before, but I'm trying to make sense of the floorplates of the building in those (very detailed) renderings. From the North side, there appears to be only 7 floors above the base. From other elevations, there seems to be 9 floors above the base. The aerial view doesn't seem to indicate any floor discontinuity (eg. fewer taller commercial floors in one section, more shorter residential floors in another).

Thoughts?

Good observation. It really is that way. On the north side is office space with higher floor heights as shown in the floor plans - http://www.halifax.ca/boardscom/drc/...reet-8.2.1.pdf

Oh. Do the sections not connect through?

Looking at the floor plans, the north wing is physically connected but doesn't seem to provide access to the main (central) residential section, which is probably as planned (residential and office space separated).
