Calculating a Bricklayer’s Rate of Work

This material was developed by the KSSP and HMP Liverpool as part of their Key Skills Support Programme development project.



Prestige Design & Build, employ three Bricklayers. Each work 40 hours per week - and have a different rate / pace of working and laying bricks.
The ‘cost conscious’ Site Manager works rigidly to the programme of work – and wants to calculate how many bricks each of the Bricklayers lay in 1 week. He records how many bricks each Bricklayer lays over a period of 1 hour – and obtains the following results: -
Bricklayer 1 - lays 113 bricks in 1 hour

Bricklayer 2 - lays 106 bricks in 1 hour

Bricklayer 3 - lays 103 bricks in 1 hour


It might not appear that way at this point, but from the information the Site Manager has – he can calculate: -




  • How many bricks each lay over an 8-hour day?




  • How many bricks each lay over a 40-hour week?




  • W
    hether the job will be completed on time?


Let’s have a look at how the Site Manager calculates their rate / pace of work




Name

Amount of Bricks

Time


Bricklayer 1

113

1 hour

Bricklayer 2

106

1 hour

Bricklayer 3

103

1 hour

From the information the Site Manager would simply multiply (x) the amount of

bricks laid in 1 hour by 8 hours – and then by 40 hours.


Name

Bricks laid in 1 hour

Bricks laid in 1 hour x 8 hours

Bricks laid in 1 hour x 40 hours

Bricklayer 1

113

904

4520

Bricklayer 2

106

848

4240

Bricklayer 3

103

824

4120



The information can now be used by the Site Manager, to see if the Brickwork will be completed on time.

One example (using a chart or line graph), could be to compare, each Bricklayers output per week.
Another example may be: If the job is to construct a large factory – with say 90,000 bricks – he can calculate how long it will take the 3 Bricklayers to lay 90,000 bricks – and then compare it to the programme of work (which, is just a plan of how long the whole job should take from start to finish – with each activity separately indicated).

The information could then be showed at the next Site Meeting – perhaps in the form of a line graph. The Line Graph could be used to see if the Bricklayers are on target at the end of each week.
