The management of construction projects involves management skills as well as an understanding of the design and construction process. Construction projects have a specific set of objectives and constraints such as a required time frame for completion. Generally, project management is distinguished from the general management of corporations by the specific and finite nature of a project. The lifespan of the project is much more limited than the ongoing goals of corporate existences. Project management deals with managing material and human resources according to objectives of scope, cost, time, quality and participation satisfaction.
