Schedule of Execution (SOE)

[ali hassan]

Schedule of Execution (SOE) definition:

It is a document representing the construction program and detailing
the relevant activities, dates, allocation of labor and plant
resources, etc.

The Contractor shall complete the work and services of the project to
be executed under the contract in accordance with the schedule of
execution.


Types of Schedule of Execution (SOE)
There are (2) different forms of Schedule of Execution as follow:

1- Tabular form.
2- Graphical form.


1- Tabular form: see fig.1

It is the simplest form used for presentation of schedule of
execution.


Example:


fig (1): simple Tabular form

The chart in Fig.1 indicates that site preparation will start before
the construction of pump house and it programmed to take (4) weeks and
then the construction of pump house will begin.

Tabular form Advantages:
This method has the advantage of being simple.
It is a convenient way to advise the Contractor of necessary material
delivery dates.
It can be used for a small-scale project.


Tabular form Disadvantages:
For a large-scale project this method will not be able to represent
all relevant activities of the project and In this case, graphical
form must to be used.



2- Graphical form : see fig.2

The graphical form is generally used because of ease in visualization.
The most widely used graphical presentation of schedule of execution
is the rectangular bar chart which sometimes called milestone bar
chart or Gantt chart


Graphical form Construction: see fig.2

the graphical form include (3) main parts as follows:

A horizontal axis representing the total time span of the project,
broken down into increments (days, weeks, or months).
A vertical axis representing the tasks that make up the project.
A graph area which contains horizontal bars for each task connecting
the period start and period ending symbols.



fig (2): Graphical form



Graphical form purposes:
It represents the phases and activities of a project, so they can be
understood by a wide audience all over the world.
It represents part of the triple constraints (cost, time and scope) of
projects, because they focus primarily on schedule management.
It usually used for top level reporting so management does not become
bogged down in the minutia of the project or projects.
It is used for monitoring a project's progress; it lets you see
immediately what should have been achieved at any point in time.

Graphical form Advantages:
It shows starting and completion dates for each item of work.
It indicates the items on which work must proceed concurrently
It indicates the items that overlap others and by how much.
It indicates the items that must be completed before work on others
can begin.
It can be used for comparing performance of work with that scheduled
by placing a bar above the schedule bar showing actual start and
completion dates.

Graphical form Disadvantages:
It does not represent the size of a project or the relative size of
work elements, therefore the magnitude of a behind-schedule condition
is easily miscommunicated.
When displaying a large number of works activity dependencies may
result in a unreadable chart.
Because the horizontal bars have a fixed height, they can misrepresent
resource ( team responsibilities) requirements of a project, which may
cause confusion especially in large projects.


Example : see fig.2

The chart in fig used for a Security and Access Control project. Tasks
are outlined in two sections. Each task uses a yellow triangle to
indicate the start date of the task and a green down triangle to
indicate the finish date of the task. Also shown on this schedule are
the responsible sub-contractors for the project (in the column labeled
R-E-S-P).



Schedule of Execution Terminology
Budget
A fiscal plan of operations for a given time period.
Baseline The project's original plan. Usually, the project's first set
of start and finish dates.
Dependencies
an essential concept that some activities are dependent on other
activities being completed first.
Milestone
An important event.
Resources
for team projects, it often helps to have an additional column
containing numbers or initials which identify who on the team is
responsible for the task.
Task List
The list of steps in a project.
Statement of Work (SOW)
A document describing the work to be done on the contract.
Status
the projects progress, the chart is updated by filling in the task's
bar to a length proportional to the amount of work finished.
Work Breakdown Structure (WBS)
A tree-like representation of the work to be done on a project. The
WBS graphically shows the division of work.
