The quality of the other two company's is absolutely on par and they have proven it with projects like Kings Wharf and the Trillium and dozens of other great projects around HRM over the last 25 years. The choice is Ranks, yes, but if the choice was based on the perceived notion that there is a lack of ability with regard to the other two than Rank has, to their loss, been grossly miss informed.

Well, logically, its not about lack of ability or inability, it has much to do with the perception of who might do it best. Those are solid proofs of concept though, with Kings Wharf being stand out.

Trillium didn't rise that fast out of its hole, KW was impressive given the amount of foundation work.

Sometimes on sites like the trillium their are factors, out side of the control of the formworkersl that slow things down. I believe there was a lot of indecision and drainage issues that held things up in the hole. The consultant also made a massive error in floor elevation. That stopped construction for a number of weeks. Tillium was also 3 floors below street level with no lay down area. There was only 2 levels below grade at kings wharf. kings wharf also had massive lay down area for equipment and no busy streets and sidewalks to contend with.
KW did however have the tide to deal with until the footings were poured.
Well regardless of who does the Formwork for the nova centre it's a great project and I think it will be great for Halifax.

I'm guessing the rumors must be that Lead got it? I was wondering if those two newish Potain cranes were rentals or purchased on the expectation of getting a big job like the Nova Centre. Any idea who is doing the form work on TD?

Lead is doi g the Formwork on the TD. And those two new potains are not rentals they bought em. And lead will be doing the nova centre 99% sure. But Nova centre or not, Lead needed those cranes as their fleet was pretty much straight out of the Stone Age. Oh and Ellis don owns the luffer crane being used on the TD in case your wondering.

Interesting, I've noticed their equipment is showing its age, it doesn't seem like it gets touch up paint as much as some of the other company's cranes. I figured that luffing jib was here for just for that job, until we get more projects like that there would little need for one of the local companies to invest in one.

Glad to see you are back posting though, you've provided interesting technical answers on previous threads.

The Nova Centre is such a large excavation site that it made me wonder how it compares to other well known excavation sites. Here is the Nova Scotia Webcams view of the Nova Centre - http://www.novascotiawebcams.com/hal...struction.html

For comparison, the side by side comparison (image below) of the two former World Trade towers and Nova Centre seems to indicate that both World Trade towers could have fit on the Nova Centre site (in fact, almost four NY World Trade towers could fit).

Based on my measurements from Google Earth, the site to be excavated is 290 feet x 330 feet. Based on an average excavation depth of 50 feet that would work out to 4,785,000 cubic feet (178,000 cubic yards) of rocky fill. If the density of the excavated fill is similar to concrete (about 150 lb per cubic foot) then that would be 718,000,000 lb or about 360,000 tons of fill to be excavated.

Another comparison is to the recently completed Dallas Cowboys Stadium. It was about 14 acres, which was excavated to a maximum of 50 feet deep (I am not sure of the average depth, but based on pictures it appears to be less than 50 feet on average). Based on this link - http://www.constructionequipmentguid...e-Future/7849/ - 750,000 cubic yards of fill was removed for the Dallas Cowboys Stadium. So the Nova Centre is about 1/4 as much as the Dallas Cowboys Stadium excavation. In my opinion, the Nova Centre is certainly in the major leagues as far as excavation goes (I wonder how the Nova Centre excavation compares with the Scotia Square excavation?)

I just happened upon this video of blasting at the Nova Centre site, uploaded to YouTube by Mike Vavra .

I was surprised by the size of the blasts; I thought that the blasting would be numerous small blasts with little visual evidence at surface level.
