[Halifax] Nova Centre | 65-58-58 m | 16-15-14 fl | Completed - Page 224

The crawler needs to come down so that last bit of building can be built. They are just stacking them up there likely to get the crawler out of the way. They can adjust them later with 2 truck cranes (one on market and one on Sackville) the tower crane is placed to fit between them.

I am starting to doubt the September 2016 estimate for completing the convention centre. They will have to move two tower cranes before they can close the convention centre off from the elements. It makes me wonder if the tower cranes couldn't have been situated differently so the convention centre could be closed off and finished inside simultaneously with the tower and hotel being built.

Moving the roof girders past the tower crane with two truck cranes looks like it would be a very risky procedure. Do you know the weight of each of the girders in tons?

Perhaps once all the roof girders are lifted to the roof, they will then be able to use the crawler crane to move them past the tower crane (since the crawler crane won't have to tilt down as much). Kph06 seems to be very knowledgeable about cranes, do you see a way that they can position the roof trusses with the crawler crane?

The crawler needs to go away soon, so they can finish that side of the building. Its in the way. The original plan was to use 2x 200ton cranes to erect the last trusses once the crawler was gone. I suspect they are now stacking them, and will move them later.

They came 3 pieces a load on a pretty standard tri-axel flat bed trailer. My ignorant reading of NSDoT regs makes the maximum weight of any vehicle + load at 26 tonnes. That seems well within the capability of one of the road cranes, but actually manipulating the trusses up and around the tower crane could need some help. But maybe from the tower crane itself.

I guess a couple 200 ton cranes should handle the job. You posted a picture of this truck crane in the Roy thread - http://41.media.tumblr.com/e8346e6a9...leqro1_500.jpg; maybe it could do the job on its own?

That is a tricky situation they are in. I hadn't been watching the webcam that closely, but it will be interesting to see how they do it. Cherubini has a 300 ton mobile crane, there plenty around in the 200 ton range.

I just happened to watch the Nova Scotia webcams for a few minutes before going to work and saw them positioning a roof girder with the crawler crane and a mobile truck crane. Here are a few screen captures showing the sequence:

That is some tricky manoeuvring!

A good amount of scaffolding also came down today around the pointed part of the office building revealing a better idea of the shape of the floorplates on that side of the tower.

kph06 · #**4470** Posted **Aug 28, 2015, 12:25 PM**

Based on the webcam it looks like the crawler is coming apart today.

Great pics! Thanks!

The crawler crane is now gone - http://www.novascotiawebcams.com/en/...s/nova-centre/.

It is good to see the crawler crane gone since they can now finish the steel work and hopefully get the convention centre closed to the elements before the first snow storm comes in a few months. Does anyone know how they will temporarily close off the two tower crane openings? (maybe they will build temporary interior walls around the crane bases).

Ziobrop posted this picture on his Built Halifax tumblr page - http://novacenter.builthalifax.ca/ Is this exterior cladding? It would be great news if it is.

Those look like unitized curtain wall sections. Flynn may be getting ready to start installing

Interesting. Is Flynn the name of the contractor doing the curtain walls, if so, will they be doing the entire Nova Centre?

Jonovision · #**4476** Posted **Aug 30, 2015, 9:12 PM**

How come it looks so green?!

Yes Flynn is the contractor. But, they are not doing all of the project. The bottom 2-3 levels are being done by Royal Door. and I have heard there is one, maybe two others, doing the work on the hotel portion.

The whole facade isn't curtain wall so that makes sence. There is a lot of brick, and I would imagine other panel wall stuff.

I am looking so forward to finally finding out what hotel is going into this site!
