PROJECT

is defined as non-routine, nonrepetitive, one-off undertaking, normally with discrete time, financial and technical performance goals. It may also refer to a specific finite task to be accomplished.

2
New cards

PROJECT MANAGEMENT

Is the overall planning, control and coordination of the project from inception to completion aimed at meeting a client's requirements and ensuring completion on time, within cost and to require quality standards.

3
New cards

CONSTRUCTION MANAGEMENT

s an arrangement whereby the tasks of planning, designing, and constructing may be integrated by a project team

4
New cards

Construction planning

encompasses the initial phase of project management, where project objectives, requirements, and constraints are defined

5
New cards

site analysis, risk assessment, and the development of strategies to address potential challenges.

Key considerations in construction planning include

6
New cards

construction project scheduling

involves the creation of a detailed timeline that identifies when specific tasks and activities will be executed throughout the project lifecycle

7
New cards

Planning and scheduling

are both essential to construction management because without the right planning and scheduling, you can't ensure that your projects come in under budget or before their deadlines

8
New cards

• The specific work to be performed

• Estimates to be documented for tracking, and controlling the project

• Commitments that are planned, and agreed to by stakeholders

• Project assumptions and constraints

• The size of the project in terms of peso and resources

• Project schedule

• Project risks

The project planning activities and goals include defining

9
New cards

Why Planning and Scheduling Are Important in Construction Projects?

11
New cards

1. Establish a logical sequence of operations.

2. Do not exceed the capabilities of the resources that are available. 3. Provide for continuity of operations.

4. Start project controlling (or critical) activities early.

General Principle of Scheduling

12

1. Critical Path Method (CPM)

2. Precedence Diagramming Method (PDM)

3. Gantt Charts.

4. Program Evaluation Review Technique (PERT)

The Most Popular Construction Planning and Scheduling Methods

15
New cards

1. Critical Path Method (CPM)

network-based scheduling technique that first identifies the critical path of a project.

16
New cards

critical path i

is the longest sequence of activities that must be completed for the project to be finished on time.

17
New cards

2. Precedence Diagramming Method (PDM)

M is more flexible than CPM and can be used for projects of any size

18
New cards

Gantt Charts.

- can be used for projects of any size and are especially useful for large projects

are a type of bar chart that is popular in construction for their ability to show the relationships between activities

19
New cards

4. Program Evaluation Review Technique (PERT)

network-based scheduling technique that is similar to CPM and PDM.

- is a more complex scheduling technique and is best suited for large projects.

Why PERT/CPM?

26
New cards

PERT

Booz, Allen and Hamilton,

- āœ“The emphasis was on completing the program in the shortest possible time.

āœ“ Developed in the 1950s by the Navy Special Projects Office in cooperation with ____________ a management consulting firm to help create a business plan that would coordinate the thousands of contractors it had working on myriad projects.

27
New cards

M.R.Walker of E.I.Du Pont de Nemours & Co

J.E.Kelly Remington Rand

CPM was developed by 1957

28
New cards

CPM

was applied to the construction of a new chemical plant.

āœ“the emphasis was on the trade-off between the cost of the project and its overall completion time

29
New cards

NORMAL TIME

approximates the most likely time to finish an activity.

30
New cards

CRASH TIME

time that will be required if no cost is spared in reducing the project time

31
New cards

NORMAL COST

cost associated with finishing the project in the normal time

32
New cards

CRASH COST

- cost associated with doing the job on a crash basis to minimize completion time.

33
New cards

Program Evaluation Review Technique (PERT)

Suited for research and development projects which are generally nonrepetitious in nature and are therefore sometimes called once-through projects Duration time for activities is subject to uncertainty

34
New cards

Critical Path Method (CPM)

- Used to compute earliest and latest possible start time for each activit

Algorithm used for planning, scheduling, coordination, and control of activities in a project

35
