Math for 1000 sq.ft ranchers inside and out walls is 195 feet ( not including the footings )

Im not sure on the concrete mix at the moment using the Self Consolidating Concrete Interior Columns and Slabs mix its 50 MPa @ 56 days costs 225 m3 , Im still working on the total but it seems like $7300 bucks

Im trying this again this time using a ICF manufacturer method

6.25” WALLS
STEP 1: Take the square footage of all wall area and subtract the square footage of all window and door openings.
STEP 2: Multiply by 0.521ft (the width of the cavity) to get the cubic feet of concrete required

STEP 3: Divide by 27cf to determine the yards of concrete required (or divide by 35.32 to determine meters required)
Example: 1845sf of wall area minus 322sf of window and door are equals 1523sf of net wall area. 1523sf times 0.521ft equals 793cf divided by 27cf per yard equals 29.4 yards of concrete Or divide 793cf by 35.32 for meters required. In this case, 22.5.


With a 1000sq.ft rancher inside wall included it works out to 46 m3

$225 m3 x 46 m3 = $10,350

It sounds too good to be true.I'll price the footings roof and forms tomorrow
