It will be interesting to see them push this 2nd tub girder over the Exhibition Hall towards Prince Street. Picture by Ziobrop - http://novacenter.builthalifax.ca/post/100672996893

"Police say a hammer drill worth $40,000 was removed from the corner of Market and Sackville streets some time between 5 p.m. on Friday and 8 a.m. on Monday. It happened across the street from the new Nova Centre construction site."
Don't they have any security at the Nova site? First the lads scaling the crane and now a big drill gone. What wit that?

Its actually one of those jackhammers that attach to the end of an excavator. I googled the part number since the police release made no sense.

Went to a great show at The Carleton last Thursday. I have to say that for my tastes I don't see what that barrier adds to the area. I would rather just see the construction site, but maybe that's just me.

I noticed yesterday that most of it has been removed

Probably for the best. A view of construction is far superior to an art barrier, IMHO.

This picture on Ziobrop's tumblr blog shows the 2nd tub girder after being moved along the concrete support ledge http://novacenter.builthalifax.ca/image/101423158238. Here is the Nova Scotia webcams link - http://www.novascotiawebcams.com/en/webcams/nova-centre/.

I have a few questions for anyone who has been watching the construction process:

1) It appears that they didn't finishing moving the 2nd tub girder, was there a problem (such as a tight fit, i.e. interference with the existing concrete structure) that delayed them, or is it just a very slow process?
2) What is the method of moving the tub girder, how is it pushed along the ledge? (does the crawler crane assist in the process?)
3) On the 2nd girder there is a steel grid along the top (almost ladder like) that isn't on the 1st girder, and I think they fabricated this structure on site. Does anyone know the purpose of the grid/ladder structure and why it isn't on the 1st girder?

The first two are slightly shorter.
They have a temporary piece on the end to allow them to move. They now need to remove that in 2 phases before pulling it into final position.

The girder is on Dollies and is pulled with 2 6ton chain pullers

The grid was fabricated off site and installed. I believe it simply supports the forming for the concrete deck. It needed to go on before being moved so the crane could position it. The first girder is staying in place and can b done later

Thanks for answering all my questions. It is amazing that only two 6 ton chain pullers are required to pull it, but I guess as long as they minimize the friction created by the dollies on the concrete ledge then not much force is required to pull it.

the art barrier was stupid, the city paid around 100,000 just to have it put in place. A art barrier would be good for something like the maple or the skye lot but not in this instance. I don't think the person making the decisions has the basic grasp of whats appropriate in each situation; most likely the councilor for the area.

Ah well, Halifax is apparently made of money. $100K for an art barrier that lasted a week, or for painting some lines on pavement to make a bike lane that nobody wants or uses.

Bike lanes costs $100k? Seriously? It's a line of paint Keith.

The view already looks more coherent with the buildings rising.

Is it just me, or has this development's actual construction gone really well?

One would think they would be cheap. But not here. You can look it up.

They cost about $20,000. I dunno where the five-year figure comes from--maybe the entire five year peninsular plan, projected to cost about that much. Compare with Toronto's Jarvis lane, which cost $86,000, or their Sherbiurne cycle track (a poorly executed separate lane) which cost 2.5 million, for some reason.

Vancouver is spending millions on separated lanes (which are well used in that city, partly thanks to the investment in creating a complete network.)

Calgary's new cycling strategy will cost $12.5 million.

It actually looks like Halifax is spending peanuts on cycle infrastructure. Maybe the problem isn't that we're spending too much, but spending too little.

too be honest Halifax is a bit of a crappy city for cycling, its really, really hilly.

this is one of my favorite places/ cities to bike around.

Which bike lane does no one want or use?

Keith P. · #**4199** Posted **Nov 2, 2014, 8:35 PM**

Only the lunatic zealot fringe will cycle to any extent here because of the hills and climate. We are spending way to much catering to the cycling lobby by putting in some very poorly thought-out lanes that are largely unused.

I'll give your kind regards to my wife , she bikes six months of the year from downtown Dartmouth over to Robie/University.
