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.

The early stage of all
phases
Question must be
asked whether there
is any real need to
establish a project
Having two stages:

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
-

- 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?

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

PHASE 2 : PLANNING & DESIGN
- Engineering & Design:
Preliminary
engineering and
design
Detail engineering
and design

14 Prentice Hall, 2002 1-14
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.

Preliminary Engineering &
Design:
- Architectural concept
- Evaluation technology
- Process alternatives
- Size and capacity decision
-
8/12/2019 Topic2- Project Life Cycle
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

PHASE 3 :
EXECUTION/IMPLIMENTATION
-
Procurement
Construction
-

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

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

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

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
-
8/12/2019 Topic2- Project Life Cycle

- 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)

Testing & commissioning
- To see the system operate efficiently
- The activities involve mainly :
- Testing- Analyzing
- Correcting
- The major electrical & mechanical system
as a total system

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
