A rolling offset is generally an offset requiring a change in 2 directions. Eg. A horizontal offset and a vertical change in elevation. There is additional information required to answer the question. What is the angle of the fittings being used for offset? 15 deg. 30. 45? What is the change in elevation?
If this is a flat (no change in elevation offset) using 45 deg., the offset dimension (7') is multiplied by 1.4142 which is the secant and cosecant of 45 deg.
The result 7 ' x 1.4142 = 9'-10 13/16"
Again, this result is for a flat run of pipe. If we have a rolling offset with a change in elevation of say 1'. We can use the Pythagorean theorem (A2 +B2 = C2)
The result would be (1')2 + (9'-10 13/16")2 = 98.99812 sq. ft.
The square root of 98.99812 is 9'-11 3/8"

well in the upc code it says to be 1 foot away horizontal and 1 foot away vertical up or below either pipe. For mains in the street most engineers like to have a separation of 3 or more feet.
10" tubes require .55 cubic feet per running foot of "tube" length.
Please - , first define your size ! -You have given a decimal figure, but of what, - -an inch, a foot, an orange,a candy bar ? ?If it is 0.393700 of an inch, then I would use a 3/8 or 10mm wrench.
A foot valve is something that you eat with your foot
There are many variables to this answer. What is the cost of forming and pouring? The labor cost of finishing as well as screeding. What is the cost of the product? Are there any other added costs? (this could include anything from pumping to fiber strands for strength) What slope would you have to have the concrete poured at.....you get the idea....sometime you can just consult your contractor and get HIS price per foot to complete your project. To figure the exact cost would require a lot more information. Contractors in your area could probably give you a "ballpark" figure if that would be close enough for you.
