Tips/hints for constructing the floor:

The method statement states that taking two days to mix concrete with a concrete mixer on-site is not feasible. ReadyMix concrete must therefore be used. Cement trucks can notionally deliver 6m³ of concrete per delivery.

Use the following productivity outputs and factors for your calculations:

Productivity outputs table
Activity	Labour	Hours	Unit
Filling excavated material into wheel barrows, wheeling and depositing less than 50m away	1 general worker	1,25	Hrs per m
Spreading and levelling, filling in 150mm	1 general worker	0,5	Hrs per m
Compacting in layers	1 general worker	2	Hrs per m
Placing of concrete, strike off and cure	1 general worker	4	Hrs per m
Allowances		Percent
Shrinkage of fill material		11 %
Wastage of fill material		5%
Wastage of ReadyMix concrete		5%
