This has been an incredibly strenuous task. As I'm a statistics nut, I did some calculations.
| Work Description | Pounds Lifted | Running Total |

All told, we used 96 deck blocks, each of which weigh 45 pounds. I would estimate that we
picked up and moved each deck block about six times in all -- sometimes for lengthy "carrying"
trips from their stacking place, sometimes just shifting them about. So that's lifting a total
of 25,920 pounds, or almost 13 tons, over the course of three weeks. Or 576 repetitions of 45
pound weight lifts. | 25,920 | 25,920 |
Then there's the lumber: we had 78 2x6x16, 42 2x6x12 boards. The delivery people just tossed
them into our yard like matchsticks, and then we had to lift each and every one to restack
them so they wouldn't warp, and THEN we of course had to lift each piece of wood at least
one additional time, generally more than that, to place them properly. So, let's say that
each board was lifted 2.5 times.
Each 2x6x16 = .1667ft x .5 ft x 16ft = 1.33 cubic feet
1.33 * 78 = 103.74 cubic feet
Each 2x6x12 is .1667ft x .5ft x 12ft = 1 cubic foot
1 * 42 = 42 cubic feet
Pine weighs 520 kg/m cubed, or 32.4 pounds per cubic feet (re
Adonis Timber Group), so:
(103.74 + 42) * 32.4 * 2.5 = 11,805 pounds lifted.

Before that, we brought in our OWN wood for the 4x12 deck, which took 14 8' and 3 12 foot, or:
9 deckblocks x 45pounds x 3 lifts = 1215 pounds

Board Weight:
1 * 3 = 3 cubic foot
.6668 * 14 = 9.3352 cubic feet:
(3 + 9.3352) * 32.4 * 3 lifts each = 1,198.98 pounds

Now, we also had miscellaneous lifting, like a couple of bags
of QuikCrete and pea gravel, and then there's the drilling of (72*16)+32=1184
screws for the largest deck, (36*10)+32=392 screws for the 'eating
deck', and (32*8)+24=280 screws for the smallest utility deck.
I don't have figured in at all the
foot/weight of moving all that dirt. For one thing, I can't
seem to find a good constant to use for the weight of dirt. I
know the volume of the dirt is pretty substantial, but I just
can't figure out how to determine the weight. If you have
suggestions, let me know!

| We got our 'last' round of rocks to finish off the standing ledge at the
end of the pond, for the eventual bridge over the eventual stream, and for the steps through the back yard.
