Hi all - how to quantify blocks for single and double leaf block construction?

[Irish Rover]

Hi everyone,

 

I'm a bricklayer who's back on the trowel after several years away from the game and I must say I'm finding it tough. The physical side of it is fine (after a few hard weeks mind) but it's the information / theory side I'm finding most difficult. Even the bonding of blockwork (blockwork so far has been 80% of my work) I find a bit difficult being truthful.

 

Has anybody had any similar experiences? How did they find it? Did you feel like I do sometimes, like your serving your time all over again? ?

 

Would anybody recommend any literature for me to read?

 

Also, regards to quantifying blocks - how would you do it? Lets say I was asked to build a block (440 x 215 x 100) on edge shed and they sent me the dimensions of the slab that they wanted it built on

 

• Do I just add the length and width of the proposed building, multiply this figure by 2 and then multiply that figure by how many courses high it is going? 

            I then deduct the door and window from this figure. 

 

• Now if they now wanted to change the spec of the shed to cavity work with a 100mm inner leaf, 100mm cavity and a 100mm outer leaf how would I calculate how many blocks they would need for the outer leaf?

 

This is probably a really basic question but I just cant get me head around it! ?

 

Genuine thanks for anybody who replies.

 

Cheers,

IR.

Single skin 10 blocks per square metre, double skin 20 blocks per square metre.

 

Deduct the areas of large openings, but don't bother about smaller ones.

That works if you measure the length and width in blocks.

Thank you all for your input. Greatly appreciated.
