Learning Outcomes

By the end of this topic, you should be able to: Identify the project life cycle in

construction industry Describe the activities involve in every

phases Identify parties involve in each phases

Definition of Project Life Cycle

The period between the START and END of a project.

A project is in a continual state of change as it progresses from its start, as a need by the owner, through design development and finally construction.

Refers to a logical sequence of activities to accomplish the project’s goals or objectives.

Class Activity... Jigsaw Group Project

Review each phase and identify the party that most likely would be involved in performing the work of the phase and the party whose work will be most influenced by the results of the phase.

Identify parties as one of the following: owner, consultant to the owner, designer, construction manager, construction contractor, project manager.

Phase 1 – Concept (Conceive) Phase 2 - Planning (Develop) Phase 3 – Execution (Execute) Phase 4 – Transfer (Finish)

Typical Construction Project Life Cycle

Construction Project Life Cycle

Phase 1 (Conceptual Phase) Begins with an idea, a perceived need, a

desire to improve or add to productive capacity of the wish for more efficient provision of some public service.

Decision: What sort of project delivery system to be used? How will the various parties be related? Will the owner engaged the design professional to

prepare plans and specifications and then contract separately with a construction contractor?

Will single entity be responsible for the entire project?

Phase 1 (Conceptual Phase) Decision:

Type of contract to be used with the contractor Will the contractor be paid a specified fixed price,

regardless of the actual quantities used in the project and regardless of the contractor’s actual costs?

Will the quantities of materials be measured and the contractor paid on the basis of those quantities and pre-agreed upon unit prices for each material?

Will the contractor be reimbursed for its actual costs, plus a fee, perhaps with an agreed-upon upper limit?

The basis upon which the design professional will be paid

Phase 2 (Planning & Design Phase)

The project is fully defined and made ready for contractor selection and deployment.

3 stages: 1st stage: Goal: to define the project’s objectives, consider

alternative ways to attain those objectives and ascertain whether the project is financially feasible. Develop project brief Investigate various sites Sought public input Prepare a preliminary cost estimate Identify funding sources

Phase 2 (Planning & Design Phase)

2nd stage: Use the results of planning efforts to develop

schematic diagrams showing the relationships among the various project components

Detailed design of the structural, electrical, other systems

3rd stage: Prepare contract documents for use in contractor

selection and installation work at the construction site

Prepare written contract conditions, technical specifications, and a set of other documents related to the process of selecting the contractor and finalizing the contract with the successful tenderer.

Phase 3 (Execution)

Contractor selection phase Owner decide: use open invitation or

certain contractors will be invited to submit offers

Contractors have to consider a number of factors in deciding whether they will make the effort to assemble a proposal for a particular project.

Submittal, opening and evaluation of tenders, the selection of the successful contractor and the finalization of the construction contract.

Phase 3 (Execution) Project mobilization phase

After the contractor is selected, a number of activities must be completed before installation work can begin at the project site.

Secure various bonds, licenses and insurances Prepare detailed program for the construction activities. Convert the cost estimate to a project budget Establish the system for tracking actual project costs Organize the worksite with provisions for temporary

buildings and services, access and delivery, storage areas and site security.

Initiate the process of obtaining materials and equipment to be incorporated into the project

Organize the arrangements for labour, the other essential resource

Phase 3 (Execution) Project operation phase

Involves 3 basic areas: Monitoring and control Resource management Documentation and communication

Monitoring and controlling Compare the actual schedule against project

programme Check the cost status Quality management Manage the work safely Minimize adverse environmental impacts

Phase 3 (Execution)

Project operation phase Resource management

Concern with assigning and supervising personnel

Assuring that the labour effort is sufficiently productive

Manage materials and plants Submit various special drawings and

samples to the owner for approval prior to installation.

Phase 4 (Transfer / Finish)

As the project nears completion, a number of special activities must take place before the contractor’s responsibilities can be considered complete.

Testing and startup tasks Final cleanup Inspections Remedial work Process of closing the construction office Terminate the staff’s employment

Phase 4 (Transfer / Finish)

A set of as-built drawings that include all changes made to the original design, operating manuals, warranties and a final report.

Transfer and archive project records Conduct some sort of project critics and

evaluation Operator training
