Modelling of the Building Process in Construction Planning and Management Using I.T.

The paper describes the main principles and results of the integrated cost estimation and project management microcomputer system developed in the last years on the base of the spatial, technological and time analysis of the building process with use of the methodology of the construction technology design. This expert system is based on quick modelling of the building process by use of typical network diagrams, which are prepared in advance, created by an original construction technology network diagram method. The typical network diagrams can be modified according to the spatial conditions of a certain building and to the amount of construction works and materials. Thanks to the database of construction processes and to the typical network diagrams the model of the building process including the cost assessment can be made about 50 times quicker than by use of current cost estimation or project management systems, quality assurance checklists, environmental plans and plans of the safety at work included.
