2. Explain how scheduling is used in the pre-
construction, construction, and post-
construction phases of a project.
Explain the configuration and uses of a bar
chart.
Explain the configuration and uses of a network
diagram.

3. • Scheduling is the process of listing a number of
duties or events in the sequence that they will
occur.
• It is a timetable, and it formulates the activities
that must be accomplished to reach a certain
goal or objective.
• Schedules establish the start, duration, and
completion date of a project or a task.

4. Partial occupancy – The practice of allowing the
owner to begin occupying the facility while
construction is still underway.
Bar chart (Gantt chart) – A simple diagram showing
project activities depicted as horizontal bars
arranged along a time line.
Network-based schedule – A more complex and
sophisticated project schedule depicting project
activities arranged in a network, representing the
logical relationships between activities.

6. Scheduling is critically important during the pre-
construction, construction, and post-
construction phases of a project.

7. While a project is still being designed, the owner needs
to know if the project can be completed on time. To
obtain project financing, the owner must generally
establish firm commitments with the end user of the
project. For example, in the case of a highway, the
owner (the government) makes a firm commitment
with the user (the public) to complete the highway
by a certain date. If the project is a commercial
shopping center, the owner makes a commitment
with private retail tenants that the facility will be
ready for occupancy at a specified time.

8. • A carefully prepared project schedule is the only
practical way to accurately predict whether the
required completion date is actually attainable. This
schedule must accurately identify all tasks required
to be completed on a project. It must determine the
duration of each task and place all tasks into a
correct, logical sequence.
• The scheduling process during the pre-construction
stage should be viewed as an opportunity to think
through all aspects of project planning, prior to the
actual construction. This process provides an
opportunity for all parties to visualize the process
and to make all necessary project coordination.

9. Project schedules are not only useful during the pre-
construction stage; they are also essential to the
successful coordination of day-to-day construction
activities. Material deliveries and the utilization of
equipment and people are all managed through
the schedule. As a project progresses, delays
inevitably occur. The project manager's job is to
deal effectively with these delays and to anticipate
them as much as possible. It is the intelligent
response to bad weather, failures, strikes, design
errors, or omissions that separates a well-
managed project from a poorly managed one.

10. As a project nears completion the end user of
the facility becomes more involved in the
construction process. Most projects require
testing and acceptance of equipment,
training of the people who will ultimately
use and maintain the equipment on the
project, and the correction of deficiencies
included in the project punchlist.

11. The bar chart, or Gantt chart, is graphically the
simplest of the scheduling methods.
The bar chart is frequently used in the planning
stage of a project by owners, designers, and
construction professionals to quickly
examine the overall timing on a project.

12. In its simplest form, the bar chart can depict a project
in terms of just three major activities (each
represented by a bar)—design, bid and award, and
construction. A somewhat more detailed bar chart,
representing seven activities (procure formwork,
mobilize, lay out footings, excavate footings, concrete
formwork, set base plates, and erect steel).
The Gantt chart effectively communicates the
following important facts about the project:
The planned overall length of the project
The planned duration of each project component
The calendar start and finish dates for each project phase

13. The most powerful tool for construction project
scheduling is the network schedule. A network
schedule depicts all of the work to be performed
on the project as a series of activities, each of
which is a well-defined item of work. Each
activity is assigned a duration (how long the
activity will take in hours, days, or weeks), and all
activities are connected together in a network
diagram that fully depicts the logical relationships
between activities.
