I guess the TTC/City of Toronto have never learned to be, the Boss,
..where is the inspection when these things are happening

Most of the work I've seen has involved excavating the existing track bed completely, often down to native soil.
It's easy enough to screw up by a few centimetres doing construction layout. I am surprised it doesn't happen more often. Sometimes it's as simple as misreading an off-set on the stake. I've seen that land a sewer on the wrong angle before ... oops. Though that was a greenfield site, with more similarities to Leslie than the typical rebuild.

Hilarious. Please explain to me how an inspector is expected to inspect thousands of points to ensure that the layout is 100% correct at every single location on every single job. At that point, the inspector might as well do all of the layout themselves, and then they wouldn't be inspecting anything else, and we would have to hire another inspector to do the inspections.I guess the TTC/City of Toronto have never learned to be, the Boss,

True.
On the other hand, I was suprised at how much concrete was sticking out of the ground when I was standing at Queen/Leslie a couple of weeks ago. And looking at the photos currently Steve Munro's site ... it does look high -
Though hindsight is 20/20 ... and perhaps that's about when they did start noticing something seemed amiss.

The key word here is concrete. You noticed the error after the concrete was placed. When it's too late.
It's not as easy to notice an error in formwork placement as it is to eyeball concrete after forms are stripped.

And before anyone accuses me of making excuses for the contractor. Let me be clear. I'm not. They made an error, admitted it, and I'm sure they will face the penalty for that. Should they miss any deadlines, then the TTC should hold them to account as outlined in the contract.
But beyond that, unless the contractor is undeniably incompetent, there is really nothing to see here, as this sort of thing happens on all sorts of projects. And it isn't necessarily an indictment of the competence of either the TTC or the contractor. I can't think of one project in the last few decades, whether it be municipal, provincial, federal, private business, hospital, residential developer, residential homeowner or whatever, union and non-union, that I've worked on and not seen someone make a mistake. It happens.

Sounds like another oops surveyor mess like St Clair here. What got built wrong? Was it the trunk line or the U track frame?
I have miss things doing inspection on site to the point it either pointed out to me, miss all together or I see it at some future visit.

Just curious, wouldn't it be easier to put down more sand/gravel and raise the level of the road, than to tear up the tracks and re-lay them? In the photos it looks as though the road hasn't been surfaced yet. If the measurements were made at the end and the track is level with the road at the ends, then raising the centre sections as needed should interface correctly with the connecting road sections.

That would make the road higher than the surrounding land, screwing up drainage, and also the ramp to the nearby condo.
That was essentially Option 3 listed in http://stevemunro.ca/2015/05/28/another-delay-for-leslie-street/

May 24 and more up on site now.
You can see the green roof, but hard to get a good shot of it. Haven't try the east end yet.
The last remaining section of the tracks from Leslie to the yard could be done this week. This will allow the building of the north traffic lane as well the new sidewalk. Once done, the the southbound lane and sidewalk can be finish off.

Thanks for the update. Cool to see it slowly come together.

My neighbour is a TTC electrician who works near the Barns, and he told me the other day that this building has been sinking. Has this been noticed as a problem? Or is he just embellishing?

Could be either. All buildings settle. Many are designed to take this into account (known as superelevating a structure). Sometimes they settle too much.
