Wall panels of 1.5 sq m area were built by one bricklayer and two assistants using both conventional brick and block masonry systems with different construction methods, to assess the relative productivity of the different systems. Work was classified as direct, indirect and non-contributory, and utilisation of time by each team member was determined using the work sampling technique. Compared with conventional brick, a productivity enhancement of 80-120% was achieved using dry-stacked masonry, and 60-90% for thin-jointed and mortar-bedded interlocking-block masonry. 15 refs.
