A construction manager tries to complete a construction project within its duration and budget using
available resources. Schedule networks such as Bar-chart and CPM(critical path method) are used to finish
the project within the duration. A survey shows that small contractors prefer Microsoft Excel to commercial
time management softwares to manage construction time in their fields, because the Excel is useful to
control cost with schedule and few time management experts works in the small contractors. A college
produces talented graduates who are able to manage time of a construction project. But the quality and
quantity of college eduction for time management is insufficient. Another survey shows that majors in
Architectural engineering of local national universities have the curriculum for time management, and teach
mainly the theory of network scheduling and how to make the network schedule. The several majors have
classes for the theory and exercise of commercial time management softwares in several majors. It is
necessary to educate time management experts able to use Bar-chart and commercial time management
softwares for the small contractors.
