Miscellany Toronto Photographs: Then and Now

(Does anyone know why The Esplanade doesn't link up with Mill Street?)

This question was posted in 2011.
If it hasn't yet been answered, perhaps this 1894 view may explain the unconnected Esplanade and Mill St.

[QUOTE If it hasn't yet been answered, perhaps this 1894 view may explain the unconnected Esplanade and Mill St./QUOTE]

Yes, it never was connected and, in my opinion, that's a good thing. The Esplanade is a residential street (as is Mill these days) and it would really not be suitable for through traffic. Front Street is only about 300 metres away to the north and Lake Shore Blvd is no further away to the south. Not everything needs to be on a grid!

CN Tower - Slipform Rising - June 26 1973 to final completion on February 22 1974

February 22 2014 marks the 40th anniversary of the last bucket of concrete poured to complete the CN Tower's main shaft on February 22 1974 at 7:32am in pea-soup fog after a night of cold and driving rain. The process had started on June 26 1973 (please refer to the previous pictorial collages).

Slipform Rising - July 1973 to Feb 1974.jpg


Refer to the following link for the home page of all CN Tower construction anniversary collages: http://www.flickr.com/photos/40744368@N04/sets/72157632200955200

Among those on hand at the 1464ft level, of the last remaining portions of the wood & steel slipform, were Sir Norman MacMillan (Chairman & President of CN Rail), Donald Macdonald (Minister of Energy, Mines and Resources), Bud Andrews (CN Tower Project Manager), Malachy Grant (Director of Design and Construction), Andre Jordan (Project Manager), Len Varey (Project Superintendent), Wally Kolodziej (Field Engineer), Maurice Grandmont, George Wilkes (safety boss), Marc Cummins (hoist engineer foreman) and Bob Feltman. Deck supervisors were Mike Burr, Keith Solomon and Mark Varey.

For the record, the following are the height of the slipform over its upwards travels: Aug 21 - 340ft, Aug 28 - 430ft, Sept 4 - 505ft, Sept 18 - 680ft, Sept 24 - 785ft, Oct 3 - 875ft, Oct 15 - 1002ft, Oct 24 - 1078ft, Nov 14 - 1122ft, Nov 29 - 1168ft, Dec 4 1973 = 1201ft, Jan 8 1974 - 1245ft and Feb 22 1974 - 1464ft.

As some trivia for old CN Tower personnel, the name "Susie" (of the wooden pin-up girl bolted to the side of the tower's main crane) came about from a lady called Susan at Sika Chemicals who held an interest with asking questions about the CN Tower.

--------------

The slipform was used to create the concrete shaft from the foundation all the way to the 1464ft level, being jacked up one inch every 5mins. The slipform was designed, engineered and put into operation by Doug Sumner, P.Eng.

The slipform is a wooden form of 2 parallel walls using 4ft high plywood. Construction workers cross-tied rebar into the empty portion of the form, poured concrete into the wooden form, jacked the form upward, and repeated until the entire shaft was completed. The entire slipform structure, and its jacking mechanism, sat on steel rods placed within the curing concrete walls. Concrete is lifted from trucks on the ground to the slipform using a fairly simple and effective cable-hoist system, transferred to human transported wheel barrels on the top platform, and then poured into holes located on the top platform which route the concrete down flexible and moveable "funnels" to the second level where workers hand pour the concrete into the wooden forms.

The slipform had 3 main levels: the top level deck was where the workers carted the concrete via wheel barrels to the holes in the upper desk. The mid-level deck was where the concrete dropped down via a chute into the wooden forms (as seen in the lower-left image above). The lower-level outside and inside decks were where the cured concrete was manually finished off with troweling.

Upwards of 50 men would work in each shift, both on the slipform and on the ground as support personnel. There were 3 shifts per day allowing for continuous concrete pouring for 14 months, except for several weeks due to strikes. No work was done on weekends due to the cost of overtime. Work was done in rain, sleet and snow, regardless of the weather. Note: as a common myth and misconception, the entire shaft was not poured in one continuous run until completed – strikes by workers and weekends would bring the work to a halt.

Special jacks would be used to pull the ends of the slipform structure inward (to make the legs taper) and also to squeeze the concrete forms narrower to make for walls that got narrower as the tower raised up. In total there were about 50 hydraulic jacks used on the main slipform. As the slipform became more narrow, the steel and wood would be cut off from the ends and lowered to the ground by crane, such that most of the slipform was gone by the time the legs were completed at the 1464ft level. The middle part of the slip form, used to create the "hexagonal core" remained unchanged from the ground level all the way up to the completed 1464ft Space Deck level.

This Feb 22 2014 collage took many months of preparation and execution, including the interviews of Doug Sumner (the tower's primary engineer, who provided most of the photos seen in this collage), Bryan Hunt (the tower's purchasing manager, who kindly provided the photo of the Topping Off Ceremony - scanning by Jack Hayward) and Graham Bezant (who took the iconic Feb 22 1973 shot of the tower from a bucket hanging from the crane). Interviews, photo scanning, photo cleanup, research & writing, Photoshop layout and media communications + relations by RC Lansdale.

This history and that Flickr album is pretty compelling stuff, lansd. Thank you for putting it all together. Funny, I've only been up that thing twice. :)

Then.

1954-ish.

[1954 is the year given by the Toronto Archives when this picture was created as a 'record'.]

We're looking at the SW corner of Queen and York - note the street signs. The Ontario Supreme Court building is going up.

There aren't many pictures online -that I can find - of this handsome mid century legal building. Here is a glance of it in this picture [right hand side, with the flags] taken on January 17, 1979.

Now. That's the Canadian Opera Company's Four Seasons Centre for the Performing Arts.
