CYCLE

PROJECT LIFE CYCLE

- Period between the beginningor start and end or completion

of a project.

- Understanding of project life

cycle phases permits

managers to better control

resources to achieve goals.


3/31

3 Prentice Hall, 2002 1-3

lesson outcomes

students are able to:

Describe phases involved in

project life cycle.


4/31


REVISION

What is project? What is characteristics of project?

What is project management? What is elements in project management?

Projects Life Cycle?


5/31


QUIZ !!

Connect the nine circles below using no morethan four straight continuous lines, without

removing your pen/pencil from the paper.


6/31

Projects life-cycle phase:

Phase 1 : Concept (Pre-

construction)

Phase 2 : Planning & design

(Procurement)

Phase 3 : Execution

(Construction)

Phase 4 : Finish (Close-out)


7/31


Conceptual Design & Planning

Execution(Planning,

Scheduling,Monitoring &

Control)

Evaluation &Termination

The early stage of all

phases

Question must be

asked whether there

is any real need to

establish a project

Having two stages:

info gathering and

taking decisionSelect a team

members that will

answers to: What?

How? When?

Where? and What?

Baseline schedule,

budget, time and cost

managementIssues, risk,

reporting,

monitoring,

approvals,

communication etc

Celebrate project

10/31

PHASE 1 : CONCEPTUAL/ FEASIBILITY

STAGE

- Preliminary evaluation of an idea

(conceptual analysis, schematic design &

design development )

- Preliminary analysis of risk and impact

on time, cost and performance

requirement

- Technical & economic feasibility

- EIA


11/31

- Location?

- Supply of skills & productive workers?

- Available of raw material?

- Adequate sources of energy ( water, oil,ect)?

- Environment impact?

- Access to the most appropriate &

Economical form of transportation?


12/31


3. Characteristic of Project (cont.)Conceptual planning

Very important for the owner (e.g., big storechains)

During this stage the owner hires key consultants

including the designer and project manager, selects

the project site, and establish a conceptualestimate, schedule, and program

The owner must gather as much reliable

information as possible about the project The most important decision is to proceed with the

project or not


13/31

PHASE 2 : PLANNING & DESIGN

- Engineering & Design:

Preliminary

engineering and

design

Detail engineering

and design


14/31


3. Characteristic of Project (cont.)Design Development

Designing the main systems andcomponents of the project.

Good communication between owner,

designer, and construction manager iscritical during this stage because selections

during this design stage affect project

appearance, construction and cost.


15/31

Preliminary Engineering &

Design:

- Architectural concept

- Evaluation technology

- Process alternatives

- Size and capacity decision


16/31

Detail Engineering & Design:

- Involved the process of breaking

down, analysis the structure and its

element to comply to the standard ofsafety and performance

- Sets a working drawing


17/31

PHASE 3 :

EXECUTION/IMPLIMENTATION

-

Procurement

Construction


18/31

Procurement

- Contractor selection phase

- Involving 2 major activities

contracting Sub-contracting

- Single contracting

- The main

contractor handle

all sub-contracting

-Design-built project

- Contractor handle the

procurement

responsibility


19/31

Homework

- Discuss the methods used for

obtaining tenders.


20/31

Contract Document

Final preparation of the documents necessary for the bid

package such as the drawings, specifications, general

conditions, and bill of quantities

All documents need to be closely reviewed by theconstruction manager and appropriate owner personnel to

decrease conflicts, and changes

With the contract documents are almost complete;a detailed and complete cost estimate for the

project can be done Designing the main systems and

components of the project


21/31

The project formally transits from design into

construction

This stage begins with a public advertisement for allinterested bidders or an invitation for specific bidders

In fast-track projects, this phase overlaps with the design

phaseIf the project is phased, each work package will

be advertised and bid out individually

It is very important stage to select highly

qualified contractors. It is not wise to select

the under-bid contractors


22/31

Construction stage

- The stage where designers plans and specification arerealized into physical structures and facilities

- Involving organization and coordination of all

resources for the project including:

- labor

- materials

- equipment

- money

- method and technology


23/31

- Construction stage

Project mobilization phase

Mobilize all the equipment, resources etc

Project Operation Phase

Involved in Planning, scheduling &

Monitoring (cost, progress, documentation,

resources, quality & time)


24/31


Constructed according to construction drawing.


25/31


Constructed according to construction drawing.


26/31

PHASE 4 : CLOSURE/FINISH

Testing &

commissioning

Operation &Utilization


27/31

Testing & commissioning

- To see the system operate efficiently

- The activities involve mainly :

- Testing- Analyzing

- Correcting

- The major electrical & mechanical system

as a total system


28/31

Transition from design and construction to the actual use

of the constructed facility

In this stage, the management team must providedocumentation, shop drawings, as-built drawings, and

operation manuals to the owner organization (as-built

drawings are the original contract drawings adjusted to

reflect all the changes that occurred) Assessment of the project teams performance is crucial

in this stage for avoiding mistakes in the future.

Actual activity costs and durations should be recordedand compared with that was planned. This will serve as

the basis for the estimating and scheduling of future

projects
