A computerized system to schedule high-rise building construction has been developed using line-of-balance technology assisted by an expert system. A review of the recent literature on the techniques available for scheduling and controlling construction projects of a repetitive nature shows that Gantt charts are inadequate, and that there are serious problems with using network methods in such circumstances. There is evidence that the construction of high rise buildings has a decidedly repetitive nature but differs in some respects from other repetitive projects such as pipelines or pavement construction. Two new concepts have been introduced into line-of-balance methodology to accommodate the special conditions encountered in high rise building construction. These two concepts, namely ’flexible’ unit networks and ’multi-level’ LOB diagrams have been coded into a scheduling module (’Lobplans’). A series of databases have been compiled regarding the productivity of resources. An expert system module (Lobex) has been developed to facilitate decision-making at network generation level. The scheduling module, the databases, and the expert system have been organized into an integrated system (Chriss) by means of communication and command routines that interface between the modules and the user input. A 16-storey building project has been used in testing Chriss’ performance. The integrated system proved to be user friendly and reliable.
