d) Characteristics of project

 

In general, the term 'construction project' refers to a high-value, time-bound, special construction mission with pre-determined performance objectives. Construction projects employ huge resources of men, materials and machines. The construction project mission is accomplished within complex project environments by putting together human and non-human resources to form a temporary organization (like the special mission task force of the army), headed by a project manager.

a.      Characteristics of project

A project has the following characteristics:

 

1.      Specific objectives

A project has clearly defined specific objectives. It is focused on end results. A project without objectives is unthinkable. Its output is measurable. The objectives are predetermined.

2.      Life Span

All projects have a life span. It has definite beginning and end. Projects cannot continue endlessly. A project is a one-time- only set of activities, it is a temporary endeavor. Its life span can be short or long depending on its nature and scope. It has a life cycle consisting of formulation, planning, implementation and termination phases.

3.      Constraints

All projects have constraints. A project operates within the constraints of time, cost and quality performance. It has a time schedule for various activities and a completion date as deadline. It has clearly laid down quality specifications. The scope and boundaries of a project are clearly delineated. Project schedule sets deadlines.

4.      Unique

Each project is different. No similar project do exist. Clearly, no two projects are exactly similar. Every project is unique in some elements. It consists of customized non-repetitive activities. It has a specific geographical location. It involves complex set of activities.

5.      Team Work

Projects work through team work. A project consists of multi-functional team. Team members are temporarily assigned from other functional departments and or required human resources from various disciplines with varied experiences are pulled together to form a temporary organization. The project manager is the leader of the team. He/She coordinates project activities. He/She builds and maintains a cohesive team. He achieves unity in diversity. He/She effectively manages conflicts. The manager is supported by a project team.

 

 

6.      Flexibility

Projects have flexibility. They are not rigid. A project operates in a dynamic environment. It needs flexibility to provide rapid response to changing environmental forces. The project complexity produces risks. Flexibility is essential to control and manage project risks at different stages of life cycle. Project risks can be related to time, costs, technology, scope and performance.

7.      Resource Integration

Projects consume and coordinate resources. A project integrates physical, financial, human information. It maintains appropriate interrelationships with them. Resource use is prioritized in disciplined way for optimization.

8.      Planning and Control

Projects work to a plan. A project requires effective and efficient planning and control systems. Standards are set for project activities through planning. They serve as yardsticks for measuring project performance. Actual performance is compared with standards to find out deviations. Corrective actions are taken to control deviations.

9.      Contracting and subcontracting

Most projects are contract-based. The project work is characterized by high level of contracting and subcontracting. Contracts can be of various types, such as lump- sum contract, unit price contract, negotiated cost plus fixed fee contract and turnkey contract. Proper contract planning, and management is the key to effective project management.

10.   Beneficiaries

All projects have beneficiaries. Beneficiaries are the ultimate users of the project outputs. They are the client of the project. A project has a specific group of beneficiaries. It should be focused on fulfilling or exceeding their requirements. Projects should clearly identify the needs of their beneficiaries
