God help us when they start Bloomfield, St. Pats Quinpool and St. Pat's A.

I’d add Design Build Solutions (Shannex subsidiary) to the list of speedy builders. The Parkland at the Commons was fast, and their other sites, which there are many of, are using different techniques to put up buildings quick.
Dexel, Southwest, Design Build Solutions all do well at keeping the exterior envelope close to the concrete structure, I find that’s a good indicator of efficiency. Concrete takes 28 days to reach compressive strength, so the exterior is usual four floors down from the one they are pouring. Once the temporary jacking is removed, the floor can be closed in. A floor a week seems to be reasonable progress around here for a building.
There’s a few builders around that seem to wait till the concrete is done or mostly done to start closing the structure in, leading to longer build times. The Elevation on Robie was like that.
