What's a reasonable days work for a bricky in terms of number of blocks layed (medium density 18" x 9" x 4" concrete) ? This is curtain walling in a barn 'lean to' filling in between existing rsj uprights so very little cutting involved. Total job is only 450 blocks maxium and I'm trying to estimate how many days labour to cost in.
Up here the going rate is =A30.50 a block.That`s for the brickie to lay them only,you also need a labourer to mix the compo,lay it at his hand and stack the blocks so that he picks them up and lays them without stretching. He will only be able to build about four courses at a time or it all sags.
The RSJ flange may be 6mm or so. This puts the line a long way from the work. I made up some grooved hardwood blocks and used cramps to trap the line and force it to line up with the inside edge. Moving the line takes time.
I guess this is single storey work so too low for bandstands but too high to finish the job from the floor. Creating a suitable platform takes time.
Working under a roof is not easy as you either can't stand upright or you can't reach the last few courses.
The top course will all need cutting.
I'm no brickie and it took me a week to build a partition wall 35'0 wide in three bays 16'0 eaves and a pitched roof at 15deg. There was lots of cutting! Blocks 150 wide.
There are limits to how many courses you can lay a day to prevent the joints squeezing out. I recall it being about 16 for bricks but I have no idea for blocks.
The OP mentions "medium density" rather than lightweight, so the advantages don't apply. Those lightweight blocks may be thermally good news but for solidity they are pants IMHO
I'm a superintendent for the largest commercial masonry firm in the Southeast USA. We build high rises in major cities. Our niche is different than what you are asking, but 150 block per day per mason is reasonable.
You're in luck, Andrew Mawson asked that very question 8 years ago and someone finally replied last month, your news server should still have the answer available :-P
