On which construction sites have you been recently?

A year ago when I was working in construction, I remember for a standard home at least:

Planning (architects), demolition workers, excavation, foundation builders, bricklayers/concrete builders, plumbers, electricians, woodworkers, window workers, fireplace/chimney builders, painters, inner decoration guys, telecom/smarthome engineers. On one single home site. Oh, and add for at least the "big and dirty" parts of building a house at least two or three trucks with drivers.

But, of course, the companies did rarely work at the same time.
