ABSTRACT
This chapter deals with aspects of bricklaying on site that are often left to chance or left to others. In reality, poorly prepared and presented material will hamper the achievement of good quality work, and it is in the best interest of the craftsperson to see that materials are correctly stored and handled before they are used. The quantities of bricks and mortar given in the tables are based on calculation. In practice, allowance must be made for handling and wastage. Bricks are made mainly from natural materials deposited at different times, often in layers having very different physical qualities. Supervisors and bricklayers are responsible for implementing management policies for safe, careful and efficient handling, storage and protection on site in order to avoid waste of time, as well as materials. Modern tunnel kilns are continuously monitored and controlled to minimise differences in firing temperatures from one part of a kiln to another, and from time to time.
