Other research approaches concentrate on the determination of
dependencies between construction processes. Construction processes
are linked with typed building components by storing them
as status variables. Following this approach, construction processes
are described by their prerequisites and results. The assignment of
a specific building component to a typed building component is
performed manually. On this basis a proposal for the sequence of
construction processes is calculated using relational algebra. This
sequence serves as a basis for the determination of a concrete construction
schedule by a project manager. The aim of this procedure
is to improve the accuracy and quality of construction schedules
based on predefined algorithms [11].
