That was quite the over-the-top review for such blandness. She even compares the planters and little plaza to the side to "Santiago Calatrava's soaring atrium." Is she looking at the same building I am?

And it may be nitpicking, but LEED Gold isn't "at the vanguard of green". The whole thing reads like an ad for WZMH.

That really was an over-the-top review. She must be getting paid by Brookfield.
In any event, the blue fences have been moved to enclose the BA2 footprint and the new plaza is now fully accessible.

Arnell Plaza is now open
Aside from the entrances to PATH, Arnell Plaza is now open. It's a nice spot. I'll grab some pictures today.

Preserving the past at Bay-Adelaide Centre in Toronto
Cheaper to disassemble, restore off site
September 25, 2009
Preserving the façade of the Bay-Adelaide Centre required disassembling the stones and restoring it off site.
DON PROCTER, correspondent
Restoring historic masonry building facades can be a daunting task.
Just ask Sam Trigila, vice-president of Clifford Restoration Ltd., a leading restoration contractor which has collaborated with major architects and engineers on the lion’s share of façade rehabilitations in Toronto as well as many in Canada over the past few decades.
Trigila will also tell you that no two historic masonry façade projects are alike.
It is usually easier to disassemble a façade and restore it off-site than it is to do the work in-situ. It is also more economical because the cost of shoring a façade can add 30 to 50 per cent to the contract price. Still, he says it is preferable to leave facades in-situ.
“It is the right thing to do from a heritage perspective,†he says.
Restoration in-situ wasn’t an option on two of the contractor’s current projects in Toronto. One is the Bishop’s Block, a 180-year-old brick and stone building featuring five Georgian rowhouses that will be partially retained and incorporated into the 65-storey Shangri-La hotel/condo rising on University Ave. in downtown Toronto.
A second storey wall of the Georgian building had a “bow†of eight inches that left the structure in danger of collapsing so the contractor disassembled the entire building. Roughly 95 per cent of the original bricks were saved.
The contractor recently wrapped up one of its largest masonry/concrete façade projects in years — the north and east facades of the National Building, an 83-year-old 11-storey commercial tower integrated into the new 51-storey Bay- Adelaide Centre West in downtown Toronto. Like the Bishop’s Block, it had to be disassembled and restored off-site.
The National Building’s façade was deemed important because the building was part of a series of early 20th century commercial buildings on Bay St. that gave a stretch of the street the nickname the “Bay Street Canyon.â€
Most of the old building’s masonry brick was beyond repair as a result of weathering years of structural movement. One corner of the building’s foundation had settled two inches, causing extensive damage to the masonry façade, points out Trigila. A series of cracks ran up the building, including one extending almost eight storeys.
The two remaining façades consist of a two-storey crown and two-storey base of Tyndall stone (from a quarry in Manitoba) with a seven floor buff brick shaft accented by precast concrete sills, lintels and spandrel panels.
Trigila says over the years the building saw a patchwork of repairs — many of which contributed to its deteriorating condition. While much of the Tyndall stone was repairable, many of the bricks were beyond help.
Because so few bricks were salvageable, identical-looking new ones were made by I-XL Brick of Medicine Hat, Alta.
The building’s spandrel panels and lintels were comprised of precast concrete pieces – many of which were poor condition. They were replicated with molds of the originals.
However, the new precast elements are air-entrained, the old ones were not. Exposure to repeated freeze-thaw cycles caused extensive damage to many of the original precast elements. Air entrainment induces bubbles into the cast stone so when moisture freezes it fills the air bubbles rather than damages the stone, explains Trigila. Other preventative measures included replacing all the corrosion-prone original “standard steel†anchors that tied the masonry facades to the concrete structure with corrosion-resistant stainless steel anchor ties.
About 94 per cent of the original stone was repaired. Making the repairs blend into the original was “tricky and labour intensive†because Tyndall stone has an unusual mottled two-tone surface that is difficult to replicate, explains Trigila.
At the building’s base is a six-inch deep banding of Andosite stone and lead flashing to prevent salt used to melt winter ice from leaching into the Tyndall stone and causing extensive damage over the long term.
Trigila says to ensure that future repairs are done correctly to the facades, Clifford Restoration has provided the owner and heritage architect with a manual on the materials, methods and catalogue drawings of the entire restoration process.
“It ensures that future generations will know precisely what has been done and what repairs would be most appropriate,†he says.

its a nice tidy space... though it strikes me that some sort of larger than life sculpture would look good where that rectangle of grass is. Also, I look forward to seeing the plaza enclosed by buildings on all 4 sides!

An Oldenburg would add so much to that space. Another Kapoor might also fit equally well.
In reality though, a patch of grass it is and a patch of grass it will remain.

A water feature would be welcome too (would compliment Cloud Garden).
And who is "Arnell"? I must have missed the post on who the square has been named after. Thanks.
