What’s the cost of excavating around the house perimeter?
我打算对我的1950年代牧场风格的房屋进行改造，以增强空气密封并增加墙壁的R值。我打算在房屋外部增加4英寸的刚性泡沫。计划的一部分是将泡沫降低到地下室墙的基础上。
My question is this: What is a reasonable price to pay for excavating a trench, 6 to 8 feet deep by 2 feet wide, around the house? I have about 100 feet of basement wall that needs to be excavated. Can you give a $/linear foot cost?
谢谢。

Jhoin,
To determine the cost, contact three excavation contractors and obtain bids. Choose your contractor based on their reputation or their bid. That's your cost.
According to my out-of-date (2000) Repair and Remodeling Cost Date book from R.S. Means, the mobilization cost for small equipment delivered on a flatbed trailer is $435, and the cost to dig an 8 inch wide trench, 24 inches deep, is $1.32 per lineal foot. (I know these dimensions are different from your proposed trench.) The cost to excavate a trench by hand with a pick and shovel (for depths up to 6 feet deep) is $37.50 per cubic yard in light soil and $74.50 per cubic yard in heavy soil.
Martin, I would hesitate to throw numbers like that out there. There's just too much variation based on region, site conditions, etc.
David,
That's why I advised Jhoin to get three bids and choose one. As I said, "that's your cost."
I never claimed that the numbers from the R.S Means book represent the cost for Jhoin to excavate. All I wrote was, "These are some numbers from my out-of-date book," and I clearly noted that the numbers referred to different types of excavation than Jhoin is considering.
“合理”在情人眼中。
Martin,
So, since I have a 100 ft x 6 ft x 2 ft (1600 ft^3 ~ 60 cubic yards) trench to dig, I should expect the prices to be in the range of $2685 for light soil to $4905 for heavy soil (inclusive of the small equipment delivery charge). My first quote is for $6160 which by the 2000 numbers is high. I think I'll get some more estimates.

Jhoin,
Ignore Martin's numbers - they are meaningless, because they are for a different kind of trenching and excavation than you have in mind, they are not adjusted for regional variance, and they are way out of date (prices have increased as much as 50% in the last ten years).
If you're going to get other estimates, find a contractor who has a good mini-tracked excavator. A small machine, with a turntable base and a small bucket can often do this kind of work with less disruption, more precision and at less cost.
