One of our neighbors in NYC had some issues last nite with their construction. It's sort of a cofferdam constructed of secant piles and liner walls.

Anyway, say you have a 80 foot by 60 foot excavation, forty feet below sea level and directly adjacent to the Hudson river. If the water rises at 1 inch per 1 minute and 20 seconds, how many gallons per hour does that equal?

The sad part is that there are TWO excavators down there.

Big pump for that much lift

I bet it'll take longer to drain it than it did to fill it.

Nothing a little money can't fix. After all, it's only money...

The mantra of construction, when behind, throw money at the problem until it goes away.

Steve Wynn was quoted as saying, I can get more money, but we can't buy more time.

Looks like someone forgot to fill the fuel tank on the pump.

They'll just paste 100 dollar bills to the wall until it stops leaking.

This is a paraphrase of what a grading foreman told me late in the year on a mass grading project when I said maybe the rain will shut us down. He said, "They'll lay down 100 dollar bills to get in here if necessary" meaning they would use lime treatment and temporary agg base roads so the work could continue.
