Applying automated methods to the building of brickwork houses means savings in both time and cost. In principle, two different methods compete with each other: “Robots on sitei and “factory prefabrication of wall elements”. However, prefabrication has already proved its advantages with a number of different manufacturers, where robots on site have not yet succeeded beyond the prototype stage. This article describes a new flexible computer program, for the planning and manufacturing of wall elements, incorporating CAD interface possibilities. The program developed is a completely object orientated Microsoft Windows application which adopts a modular concept, thereby allowing adaptation or inclusion of the modules to other applications. The existence of such a program is regarded as a very important requirement for masonry automation.
