Block Size and Estimating

Submitted by Pilgrim (not verified) on Fri, 06/11/2009 - 22:15

We have 420 LF of 8' tall walls and an estimate of 12,285 blocks with 85% solid
if the blocks cover 216 cm2 per block, Not sure of the dimensions of the blocks
that this machine makes.
Ok thanks for any info you can give me.

Hi Geoffrey,
How are you? I hope all is well there.
I have a couple of questions for you.
1. If I have a 500 sq ft house that has 2 rooms that are 10'x15' and one common area that people sit in. How many bricks
would I need for that, if the ceilings are 8' ceilings?
Can you give me a simply formula to figure out how many sq.ft a block will cover. or better yet, how many blocks do you need for 100 square feet, it will be easy for me to figure from there I think

There are many ways to count blocks needed for a building. The wall area cannot be calculated from the floor area of a building. We need to know the total perimeter of the walls and the openings [doors and windows]. The place to start is a drawing or set of drawings. Rhino blocks [a more colorful name for ICEBs] are designed in metric, it’s easiest to do the drawings in meters or centimeters.
A 10’ x 15’ room might end up 3 meters [10 blocks] by 4.5 meters [15 blocks].
This is 150 sq ft, or 13.5 sq m
Having 2 rooms of 150 sqft leaves a 200 sqft area for a 500 sq ft house.
From the plan view [the view from the top] you can measure the length of the walls in meters and in blocks.
An 8’ foot high wall is about 2.4 meters.
Take the total perimeter of the walls [in blocks] and multiply it by the height [in blocks] then subtract out the openings [doors and windows].
