A construction project, no matter how large or

small, is made up of many individual workitems that must be completed ..

commonly referred to as activities

The first step

is to identify the activities that must becompleted in order to complete the project.


8/20

Activities have five characteristics:

1. Activities consume time.

2. Activities usually consume resources.

(cure time is a example as an exception)

3. Activities have a definable start and

finish.

4. Activities are assignable.5. Activities are measurable.


9/20

Resource Availability

The key to estimating activity durations is

the availability of resources. These

resources include the following: Labor

Equipment

Material

Subcontractors


10/20

Activity Identification-Usually entails dividing the work upbased on one or more of the following criteria-

What work has to be done? HVAC Ductwork

Where will the work be accomplished? Each floor

Who will be responsible for performing the work? Trade

When will the work be performed? Rough-In/Finish How will the work be accomplished? Part needs crane


11/20

Activity Detail

Location- In different areas?

Type of resource- More than one trade?

Timing- At different times in the project? How?- Different resource for each activity?


12/20

Activity Detail

Why would it be broken down from large to

small activities?

By location

By who performs work

Sequence

A specific reason for proper planning

Level of Detail

Owner requirement

As needed to manage the project

Sequencing & Experience

No more than five day duration as a rule by manygeneral contractors

Type of work

Hour to day durations-we will use days-not partial

days always round up Project Requirements- will identify requirements in

project specifications


17/20

The Planning and Scheduling Process

Requires the following six (seven) steps:Evaluate Work Breakdown Structure

Identify project activities.

Estimate activity durations.Develop the project plan.

Schedule the project activities.

Implement the schedule.Review and analyze the schedule.


18/20

Identify project activities.

Breakdown and analyze the project.

Review the plans, specifications, general

conditions and contract requirements.

The result of this first step is the

identification of all activities that must be

performed in order to complete the project.


19/20

Activity Description

Consistent in format

A lot of information communicated in a

short description.

Common meaning/industry terms

Concise and unambiguous

Only so many spaces in system Different description for each activity


20/20

Activity IDs

Use Software Features & Use to

Read Activity Description

Some Specifications Specify ID

Style & Length

Maintain Consistency from

Schedule to Schedule!!!!!!!
