In general, major construction works are time bound and employ huge resources of men, material and machines. They involve heavy investments, of million to billions of dollars. They require a high level of technology, and need an effective management of resources. The execution of major construction capital works is undertaken by projecting them, that is by organizing them into one or more construction project for implementation.
The term ‘construction project’ refers to a high value, time bound, special construction mission with predetermined performance objectives. The project mission is accomplished within complex project environments, by putting together human and non-human resources into a temporary organization (like a special mission task force in the army), headed by a project manager.

The project manager aims to achieve its mission by:
