ABSTRACT
The usual way of shortening the time scale is
by increasing productivity, that is, by completing
each function as efficiently as possible and starting
each new phase immediately upon completion of
the preceding phase. Everything is done in proper
order and no time is wasted. This is working faster.
Another way of saving total project time would be
by shortening of the overall project duration. This
can be achieved by overlapping some of the func-
tions, doing two things at the same time. Hence,
this would be accomplished by starting a new
phase of work where possible before the preceding
phase is fully completed. Time saved by concur-
rent work will accumulate and appear at the end
of the construction period in the form of early
overall project completion. Organizing the project
to produce early completion by the technique of
overlapping time scheduling is the essence of fast
track construction (Thomas et al. 2002).
