Materials List Revisited

[gteacher]

Glen: my numbers for cals:

Slab = 5 x 5 x .1 = 2.5 m
Footer = 18.6 x .45 x .35 = 2.9295
Chamfer = 18.4 x (.1 x .1)/2 = .092
Ledge = 19.44 x .172 x .14 = .468
Total = 5.053 exact

I believe the wall insulation is coming from the gap material, noted as insulation gap. If you change this material wall insulation changes accordingly.

However, attached is a similar plan using slab walls which is definitely wrong. Also, can’t figure out why chief added wall, ceiling and floor insulation on a all concrete structure and where its coming from?
