The results showed that the mean energy expenditure of bricklaying was 1.5l/min of oxygen (7.23Kcal/min, using a conversion factor of 4.82) which classified bricklaying as “heavy work”. A rest allowance of 64.45% (38.67 minutes rest for 60 minutes work duration) was calculated.
It was concluded that there is a need to redesign the work content of the aforementioned occupation in order to reduce excessive strain on the workers, which in turn will increase productivity.
