The Dirt Formerly Known as "The Hill"

I realize I am way behind in updating you about the hill. I so profusely apologize. I think, well, (choking up) I just couldn't bear the heartbreak of describing it.

So, yep, the hill is now almost flat. There are 2 big Komat'su excavators working literally 12 hours a day to churn, move, and transport dirt to the dump trucks, a mammoth crane/drilling do-hicky placing LONG steel beams into the ground, a constant stream of dump trucks which have quite the system of honking at one another to communicate - one honk to "move forward, your first bin is full" and two honks to say "you're full of dirt, move along" - ALL frickin' day long - and probably 30 workers running up and down the dirt mounds, spraying concrete into the beams, and yelling at pedestrians, "what about the sign "SIDEWALK CLOSED" did you not understand?!?"

Interesting to see how much faster this build is going (for a private developer) than the new county office building across the street went, or the new police station down the street went. They have a much smaller space, but have much more equipment, people, and work longer hours. My theory:

1) Government has to go with the lowest bidder.
2) Lowest Bidders have to do something to make their bids lower, like maybe utilize fewer people and equipment and thus take longer to accomplish the same results
3) Private developers sweeten the pot with incentives to finish early.

Can you negate the null hypothesis?
