ABSTRACT
When projects are to be undertaken it is necessary
to visualize all the operations of the project, arrange
these operations in their proper sequence, achieve
confidence that every participant of the building
process (the owner, the architect and the contractor)
understands each of his tasks, acquires the know-
how andmeans necessary to perform them and feels
convinced that the method chosen for performing
all tasks is the most progressive and economical.
Thus all projects have to be efficiently planned at
the investor’s (owner’s), architect’s and contrac-
tor’s sides. In the planning and design stage of the
project several specific problemsmust be solved and
many points of view have to be taken into this deci-
sion process. A lot of these questions can be effi-
ciently solved by creating of a computer model of
the building process of the project. The model must
be based on the construction technology and cost
analysis and must reflect all technical, technologi-
cal and economical features. One of the significant
questions is the utility of the project, too.
