This is more like road rather than building construction but here's a view of the Cogswell area in Halifax. The dirt-covered and grassy areas will be development parcels.
In the foreground there is a sewage treatment plant built by the city in the 2000's. Seems like a pretty big planning fail as it's now occupying a prominent site downtown. Back in those days there wasn't really a sense that this much development was coming or that high density buildings could be built there.
